6. Block diagram
The analog interface handles the modulation and demodulation of the analog signals
according to the Card Receiving mode, Reader/Writer mode and NFCIP-1 mode
communication scheme.
The RF level detector detects the presence of an external RF-field delivered by the
antenna to the RX pin.
The Data mode detector detects a MIFARE, FeliCa or NFCIP-1 mode in order to prepare
the internal receiver to demodulate signals, which are sent to the PN512.
The communication (S2C) interface provides digital signals to support communication for
transfer speeds above 424 kbit/s and digital signals to communicate to a secure IC.
The contactless UART manages the protocol requirements for the communication
protocols in cooperation with the host. The FIFO buffer ensures fast and convenient data
transfer to and from the host and the contactless UART and vice versa.
Various host interfaces are implemented to meet different customer requirements.

8. Functional description
The PN512 transmission module supports the Read/Write mode for
ISO/IEC 14443 A/MIFARE and ISO/IEC 14443 B using various transfer speeds and
modulation protocols.
PN512 transceiver IC supports the following operating modes:
• Reader/Writer mode supporting ISO/IEC 14443A/MIFARE and FeliCa scheme
• Card Operation mode supporting ISO/IEC 14443A/MIFARE and FeliCa scheme
• NFCIP-1 mode
The modes support different transfer speeds and modulation schemes. The following
chapters will explain the different modes in detail.
Note: All indicated modulation indices and modes in this chapter are system parameters.
This means that beside the IC settings a suitable antenna tuning is required to achieve the
optimum performance.
8.1 ISO/IEC 14443 A/MIFARE functionality

The PN512’s contactless UART and dedicated external host must manage the complete
ISO/IEC 14443 A/MIFARE protocol. Figure 8 shows the data coding and framing
according to ISO/IEC 14443 A/MIFARE.
The internal CRC coprocessor calculates the CRC value based on ISO/IEC 14443 A
part 3 and handles parity generation internally according to the transfer speed. Automatic
parity generation can be switched off using the ManualRCVReg register’s ParityDisable
bit.
8.2 ISO/IEC 14443 B functionality
The PN512 reader IC fully supports international standard ISO 14443 which includes
communication schemes ISO 14443 A and ISO 14443 B.
Refer to the ISO 14443 reference documents Identification cards - Contactless integrated
circuit cards - Proximity cards (parts 1 to 4).
Remark: NXP Semiconductors does not offer a software library to enable design-in of the
ISO 14443 B protocol.

8.3 FeliCa reader/writer functionality
The FeliCa mode is the general reader/writer to card communication scheme according to
the FeliCa specification. The following diagram describes the communication on a
physical level, the communication overview describes the physical parameters.
The contactless UART of PN512 and a dedicated external host controller are required to
handle the complete FeliCa protocol.
8.3.1 FeliCa framing and coding
To enable the FeliCa communication a 6 byte preamble (00h, 00h, 00h, 00h, 00h, 00h)
and 2 bytes Sync bytes (B2h, 4Dh) are sent to synchronize the receiver.
The following Len byte indicates the length of the sent data bytes plus the LEN byte itself.
The CRC calculation is done according to the FeliCa definitions with the MSB first.
To transmit data on the RF interface, the host controller has to send the Len- and databytes
to the PN512's FIFO-buffer. The preamble and the sync bytes are generated by the
PN512 automatically and must not be written to the FIFO by the host controller. The
PN512 performs internally the CRC calculation and adds the result to the data frame.
Example for FeliCa CRC Calculation:

8.4 NFCIP-1 mode
The NFCIP-1 communication differentiates between an active and a Passive
Communication mode.
• Active Communication mode means both the initiator and the target are using their
own RF field to transmit data.
• Passive Communication mode means that the target answers to an initiator command
in a load modulation scheme. The initiator is active in terms of generating the RF field.
• Initiator: generates RF field at 13.56 MHz and starts the NFCIP-1 communication
• Target: responds to initiator command either in a load modulation scheme in Passive
Communication mode or using a self generated and self modulated RF field for Active
Communication mode.
In order to fully support the NFCIP-1 standard the PN512 supports the Active and Passive
Communication mode at the transfer speeds 106 kbit/s, 212 kbit/s and 424 kbit/s as
defined in the NFCIP-1 standard.

8.4.3 NFCIP-1 framing and coding
The NFCIP-1 framing and coding in Active and Passive Communication mode is defined
in the NFCIP-1 standard.
8.4.4 NFCIP-1 protocol support
The NFCIP-1 protocol is not completely described in this document. For detailed
explanation of the protocol refer to the NFCIP-1 standard. However the datalink layer is
according to the following policy:
• Speed shall not be changed while continuum data exchange in a transaction.
• Transaction includes initialization and anticollision methods and data exchange (in
continuous way, meaning no interruption by another transaction).
In order not to disturb current infrastructure based on 13.56 MHz general rules to start
NFCIP-1 communication are defined in the following way.
1. Per default NFCIP-1 device is in Target mode meaning its RF field is switched off.
2. The RF level detector is active.
3. Only if application requires the NFCIP-1 device shall switch to Initiator mode.
4. Initiator shall only switch on its RF field if no external RF field is detected by RF Level
detector during a time of TIDT.
5. The initiator performs initialization according to the selected mode.

r/w read and write These bits can be written and read by the -Controller. Since they
are used only for control means, there content is not influenced by
internal state machines, e.g. the PageSelect-Register may be
written and read by the -Controller. It will also be read by internal
state machines, but never changed by them.
dy dynamic These bits can be written and read by the -Controller.
Nevertheless, they may also be written automatically by internal
state machines, e.g. the Command-Register changes its value
automatically after the execution of the actual command.
r read only These registers hold bits, which value is determined by internal
states only, e.g. the CRCReady bit can not be written from
external but shows internal states.
w write only Reading these registers returns always ZERO.
RFU - These registers are reserved for future use.
In case of a PN512 Version version 2.0 (VersionReg = 82h) a
read access to these registers returns always the value “0”.
Nevertheless this is not guaranteed for future chips versions
where the value is undefined. In case of a write access, it is
recommended to write always the value “0”.

10. Digital interfaces
10.1 Automatic microcontroller interface detection
The PN512 supports direct interfacing of hosts using SPI, I2C-bus or serial UART
interfaces. The PN512 resets its interface and checks the current host interface type
automatically after performing a power-on or hard reset. The PN512 identifies the host
interface by sensing the logic levels on the control pins after the reset phase. This is done
using a combination of fixed pin connections. Table 141 shows the different connection
configurations.

10.2 Serial Peripheral Interface
A serial peripheral interface (SPI compatible) is supported to enable high-speed
communication to the host. The interface can handle data speeds up to 10 Mbit/s. When
communicating with a host, the PN512 acts as a slave, receiving data from the external
host for register settings, sending and receiving data relevant for RF interface
communication.
An interface compatible with SPI enables high-speed serial communication between the
PN512 and a microcontroller. The implemented interface is in accordance with the SPI
standard.
The timing specification is given in Section 26.1 on page 117.
The PN512 acts as a slave during SPI communication. The SPI clock signal SCK must be
generated by the master. Data communication from the master to the slave uses the
MOSI line. The MISO line is used to send data from the PN512 to the master.
Data bytes on both MOSI and MISO lines are sent with the MSB first. Data on both MOSI
and MISO lines must be stable on the rising edge of the clock and can be changed on the
falling edge. Data is provided by the PN512 on the falling clock edge and is stable during
the rising clock edge.
10.2.1 SPI read data
Reading data using SPI requires the byte order shown in Table 143 to be used. It is
possible to read out up to n-data bytes.
The first byte sent defines both the mode and the address.
[1] X = Do not care.
Remark: The MSB must be sent first.
10.2.2 SPI write data
To write data to the PN512 using SPI requires the byte order shown in Table 144. It is
possible to write up to n data bytes by only sending one address byte.

Remark: The MSB must be sent first.
10.2.3 SPI address byte
The address byte has to meet the following format.
The MSB of the first byte defines the mode used. To read data from the PN512 the MSB is
set to logic 1. To write data to the PN512 the MSB must be set to logic 0. Bits 6 to 1 define
the address and the LSB is set to logic 0.
10.3 UART interface
10.3.1 Connection to a host
Remark: Signals DTRQ and MX can be disabled by clearing TestPinEnReg register’s
RS232LineEn bit.
10.3.2 Selectable UART transfer speeds
The internal UART interface is compatible with an RS232 serial interface.
The default transfer speed is 9.6 kBd. To change the transfer speed, the host controller
must write a value for the new transfer speed to the SerialSpeedReg register. Bits
BR_T0[2:0] and BR_T1[4:0] define the factors for setting the transfer speed in the
SerialSpeedReg register.
The BR_T0[2:0] and BR_T1[4:0] settings are described in Table 10. Examples of different
transfer speeds and the relevant register settings are given in Table 11.

The MSB of the first byte sets the mode used. To read data from the PN512, the MSB is
set to logic 1. To write data to the PN512 the MSB is set to logic 0. Bit 6 is reserved for
future use, and bits 5 to 0 define the address; see Table 151.
10.4 I2C Bus Interface
An I2C-bus (Inter-IC) interface is supported to enable a low-cost, low pin count serial bus
interface to the host. The I2C-bus interface is implemented according to
NXP Semiconductors’ I
2C-bus interface specification, rev. 2.1, January 2000. The
interface can only act in Slave mode. Therefore the PN512 does not implement clock
generation or access arbitration.
The PN512 can act either as a slave receiver or slave transmitter in Standard mode, Fast
mode and High-speed mode.
SDA is a bidirectional line connected to a positive supply voltage using a current source or
a pull-up resistor. Both SDA and SCL lines are set HIGH when data is not transmitted. The
PN512 has a 3-state output stage to perform the wired-AND function. Data on the I2C-bus
can be transferred at data rates of up to 100 kBd in Standard mode, up to 400 kBd in Fast
mode or up to 3.4 Mbit/s in High-speed mode.
If the I2C-bus interface is selected, spike suppression is activated on lines SCL and SDA
as defined in the I2C-bus interface specification.
See Table 171 on page 117 for timing requirements.

10.4.1 Data validity
Data on the SDA line must be stable during the HIGH clock period. The HIGH or LOW
state of the data line must only change when the clock signal on SCL is LOW.
10.4.2 START and STOP conditions
To manage the data transfer on the I2C-bus, unique START (S) and STOP (P) conditions
are defined.
• A START condition is defined with a HIGH-to-LOW transition on the SDA line while
SCL is HIGH.
• A STOP condition is defined with a LOW-to-HIGH transition on the SDA line while
SCL is HIGH.
The I2C-bus master always generates the START and STOP conditions. The bus is busy
after the START condition. The bus is free again a certain time after the STOP condition.
The bus stays busy if a repeated START (Sr) is generated instead of a STOP condition.
The START (S) and repeated START (Sr) conditions are functionally identical. Therefore,
S is used as a generic term to represent both the START (S) and repeated START (Sr)
conditions.
10.4.3 Byte format
Each byte must be followed by an acknowledge bit. Data is transferred with the MSB first;
see Figure 22. The number of transmitted bytes during one data transfer is unrestricted
but must meet the read/write cycle format.

10.4.4 Acknowledge
An acknowledge must be sent at the end of one data byte. The acknowledge-related clock
pulse is generated by the master. The transmitter of data, either master or slave, releases
the SDA line (HIGH) during the acknowledge clock pulse. The receiver pulls down the
SDA line during the acknowledge clock pulse so that it remains stable LOW during the
HIGH period of this clock pulse.
The master can then generate either a STOP (P) condition to stop the transfer or a
repeated START (Sr) condition to start a new transfer.
A master-receiver indicates the end of data to the slave-transmitter by not generating an
acknowledge on the last byte that was clocked out by the slave. The slave-transmitter
releases the data line to allow the master to generate a STOP (P) or repeated START (Sr)
condition.

10.4.5 7-Bit addressing
During the I2C-bus address procedure, the first byte after the START condition is used to
determine which slave will be selected by the master.
Several address numbers are reserved. During device configuration, the designer must
ensure that collisions with these reserved addresses cannot occur. Check the I
2C-bus
specification for a complete list of reserved addresses.
The I2C-bus address specification is dependent on the definition of pin EA. Immediately
after releasing pin NRSTPD or after a power-on reset, the device defines the I2C-bus
address according to pin EA.
If pin EA is set LOW, the upper 4 bits of the device bus address are reserved by
NXP Semiconductors and set to 0101b for all PN512 devices. The remaining 3 bits
(ADR_0, ADR_1, ADR_2) of the slave address can be freely configured by the customer
to prevent collisions with other I2C-bus devices.
If pin EA is set HIGH, ADR_0 to ADR_5 can be completely specified at the external pins
according to Table 141 on page 69. ADR_6 is always set to logic 0.
In both modes, the external address coding is latched immediately after releasing the
reset condition. Further changes at the used pins are not taken into consideration.
Depending on the external wiring, the I2C-bus address pins can be used for test signal
outputs.
10.4.6 Register write access
To write data from the host controller using the I2C-bus to a specific register in the PN512
the following frame format must be used.
• The first byte of a frame indicates the device address according to the I2C-bus rules.
• The second byte indicates the register address followed by up to n-data bytes.
In one frame all data bytes are written to the same register address. This enables fast
FIFO buffer access. The Read/Write (R/W) bit is set to logic 0.

To read out data from a specific register address in the PN512, the host controller must
use the following procedure:
• Firstly, a write access to the specific register address must be performed as indicated
in the frame that follows
• The first byte of a frame indicates the device address according to the I2C-bus rules
• The second byte indicates the register address. No data bytes are added
• The Read/Write bit is 0
After the write access, read access can start. The host sends the device address of the
PN512. In response, the PN512 sends the content of the read access register. In one
frame all data bytes can be read from the same register address. This enables fast FIFO
buffer access or register polling.
The Read/Write (R/W) bit is set to logic 1.

10.4.8 High-speed mode
In High-speed mode (HS mode), the device can transfer information at data rates of up to
3.4 Mbit/s, while remaining fully downward-compatible with Fast or Standard mode
(F/S mode) for bidirectional communication in a mixed-speed bus system.
10.4.9 High-speed transfer
To achieve data rates of up to 3.4 Mbit/s the following improvements have been made to
I
2C-bus operation.
• The inputs of the device in HS mode incorporate spike suppression, a Schmitt trigger
on the SDA and SCL inputs and different timing constants when compared to
F/S mode
• The output buffers of the device in HS mode incorporate slope control of the falling
edges of the SDA and SCL signals with different fall times compared to F/S mode
10.4.10 Serial data transfer format in HS mode
The HS mode serial data transfer format meets the Standard mode I2C-bus specification.
HS mode can only start after all of the following conditions (all of which are in F/S mode):
1. START condition (S)
2. 8-bit master code (00001XXXb)
3. Not-acknowledge bit (A)
When HS mode starts, the active master sends a repeated START condition (Sr) followed
by a 7-bit slave address with a R/W bit address and receives an acknowledge bit (A) from
the selected PN512.
Data transfer continues in HS mode after the next repeated START (Sr), only switching
back to F/S mode after a STOP condition (P). To reduce the overhead of the master code,
a master links a number of HS mode transfers, separated by repeated START conditions
(Sr).

10.4.11 Switching between F/S mode and HS mode
After reset and initialization, the PN512 is in Fast mode (which is in effect F/S mode as
Fast mode is downward-compatible with Standard mode). The connected PN512
recognizes the “S 00001XXX A” sequence and switches its internal circuitry from the Fast
mode setting to the HS mode setting.
The following actions are taken:
1. Adapt the SDA and SCL input filters according to the spike suppression requirement
in HS mode.
2. Adapt the slope control of the SDA output stages.
It is possible for system configurations that do not have other I2C-bus devices involved in
the communication to switch to HS mode permanently. This is implemented by setting
Status2Reg register’s I2CForceHS bit to logic 1. In permanent HS mode, the master code
is not required to be sent. This is not defined in the specification and must only be used
when no other devices are connected on the bus. In addition, spikes on the I2C-bus lines
must be avoided because of the reduced spike suppression.
10.4.12 PN512 at lower speed modes
PN512 is fully downward-compatible and can be connected to an F/S mode I2C-bus
system. The device stays in F/S mode and communicates at F/S mode speeds because a
master code is not transmitted in this configuration.
11. 8-bit parallel interface
The PN512 supports two different types of 8-bit parallel interfaces, Intel and Motorola
compatible modes.
11.1 Overview of supported host controller interfaces
The PN512 supports direct interfacing to various -Controllers. The following table shows

12. Analog interface and contactless UART
12.1 General
The integrated contactless UART supports the external host online with framing and error
checking of the protocol requirements up to 848 kBd. An external circuit can be connected
to the communication interface pins MFIN and MFOUT to modulate and demodulate the
data.
The contactless UART handles the protocol requirements for the communication
protocols in cooperation with the host. Protocol handling generates bit and byte-oriented
framing. In addition, it handles error detection such as parity and CRC, based on the
various supported contactless communication protocols.
Remark: The size and tuning of the antenna and the power supply voltage have an
important impact on the achievable operating distance.
12.2 TX driver
The signal on pins TX1 and TX2 is the 13.56 MHz energy carrier modulated by an
envelope signal. It can be used to drive an antenna directly using a few passive
components for matching and filtering; see Section 15 on page 96. The signal on pins TX1
and TX2 can be configured using the TxControlReg register; see Section 9.2.2.5 on
page 40.
The modulation index can be set by adjusting the impedance of the drivers. The
impedance of the p-driver can be configured using registers CWGsPReg and
ModGsPReg. The impedance of the n-driver can be configured using the GsNReg
register. The modulation index also depends on the antenna design and tuning.
The TxModeReg and TxSelReg registers control the data rate and framing during
transmission and the antenna driver setting to support the different requirements at the
different modes and transfer speeds.

The sensitivity of the RF level detector is adjustable in a 4-bit range using the bits RFLevel
in register RFCfgReg. The sensitivity itself depends on the antenna configuration and
tuning.
Possible sensitivity levels at the RX pin are listed in the Table 154.
To increase the sensitivity of the RF level detector an amplifier can be activated by setting
the bit RFLevelAmp in register RFCfgReg to 1.
Remark: During soft Power-down mode the RF level detector amplifier is automatically
switched off to ensure that the power consumption is less than 10 A at 3 V.
Remark: With typical antennas lower sensitivity levels can provoke misleading results
because of intrinsic noise in the environment.
Note: It is recommended to use the bit RFLevelAmp only with higher RF level settings.
12.4 Data mode detector
The Data mode detector gives the possibility to detect received signals according to the
ISO/IEC 14443A/MIFARE, FeliCa or NFCIP-1 schemes at the standard transfer speeds
for 106 kbit, 212 kbit and 424 kbit in order to prepare the internal receiver in a fast and
convenient way for further data processing.
The Data mode detector can only be activated by the AutoColl command. The mode
detector resets, when no external RF field is detected by the RF level detector. The Data
mode detector could be switched off during the AutoColl command by setting bit
ModeDetOff in register ModeReg to 1.

12.5 Serial data switch
Two main blocks are implemented in the PN512. The digital block comprises the state
machines, encoder/decoder logic. The analog block comprises the modulator and
antenna drivers, the receiver and amplifiers. The interface between these two blocks can
be configured in the way, that the interfacing signals may be routed to the pins SIGIN and
SIGOUT. SIGIN is capable of processing digital NFC signals on transfer speeds above
424 kbit. The SIGOUT pin can provide a digital signal that can be used with an additional
external circuit to generate transfer speeds above 424 kbit (including 106, 212 and
424 kbit). Furthermore SIGOUT and SIGIN can be used to enable the S2C interface in the
card SAM mode to emulate a card functionality with the PN512 and a secure IC. A secure
IC can be the SmartMX smart card controller IC.
This topology allows the analog block of the PN512 to be connected to the digital block of
another device.
The serial signal switch is controlled by the TxSelReg and RxSelReg registers.
Figure 29 shows the serial data switch for TX1 and TX2.
12.6 S2C interface support
The S2C provides the possibility to directly connect a secure IC to the PN512 in order act
as a contactless smart card IC via the PN512. The interfacing signals can be routed to the
pins SIGIN and SIGOUT. SIGIN can receive either a digital FeliCa or digitized
ISO/IEC 14443A signal sent by the secure IC. The SIGOUT pin can provide a digital
signal and a clock to communicate to the secure IC. A secure IC can be the smart card IC
provided by NXP Semiconductors.
The PN512 has an extra supply pin (SVDD and PVSS as Ground line) for the SIGIN and
SIGOUT pads.
Figure 31 outlines possible ways of communications via the PN512 to the secure IC.

Configured in the Secure Access Mode the host controller can directly communicate to
the Secure IC via SIGIN/SIGOUT. In this mode the PN512 generates the RF clock and
performs the communication on the SIGOUT line. To enable the Secure Access module
mode the clock has to be derived by the internal oscillator of the PN512, see bits
SAMClockSel in register TestSel1Reg.
Configured in Contactless Card mode the secure IC can act as contactless smart card IC
via the PN512. In this mode the signal on the SIGOUT line is provided by the external RF
field of the external reader/writer. To enable the Contactless Card mode the clock derived
by the external RF field has to be used.
The configuration of the S2C interface differs for the FeliCa and MIFARE scheme as
outlined in the following chapters.

12.6.1 Signal shape for Felica S2C interface support
The FeliCa secure IC is connected to the PN512 via the pins SIGOUT and SIGIN.
The signal at SIGOUT contains the information of the 13.56 MHz clock and the digitized
demodulated signal. The clock and the demodulated signal is combined by using the
logical function exclusive or.
To ensure that this signal is free of spikes, the demodulated signal is digitally filtered first.
The time delay for that digital filtering is in the range of one bit length. The demodulated
signal changes only at a positive edge of the clock.
The register TxSelReg controls the setting at SIGOUT.
The answer of the FeliCa SAM is transferred from SIGIN directly to the antenna driver.
The modulation is done according to the register settings of the antenna drivers.
The clock is switched to AUX1 or AUX2 (see AnalogSelAux).
Note: A HIGH signal on AUX1 and AUX2 has the same level as AVDD. A HIGH signal at
SIGOUT has the same level as SVDD. Alternatively it is possible to use pin D0 as clock
output if a serial interface is used. The HIGH level at D0 is the same as PVDD.
Note: The signal on the antenna is shown in principle only. In reality the waveform is
sinusoidal.

12.6.2 Waveform shape for ISO/IEC 14443A and MIFARE S2C support
The secure IC, e.g. the SmartMX is connected to the PN512 via the pins SIGOUT and
SIGIN.
The waveform shape at SIGOUT is a digital 13.56 MHz Miller coded signal with levels
between PVSS and PVDD derived out of the external 13.56 MHz carrier signal in case of
the Contactless Card mode or internally generated in terms of Secure Access mode.
The register TxSelReg controls the setting at SIGOUT.
Note: The clock settings for the Secure Access mode and the Contactless Card mode
differ, refer to the description of the bits SAMClockSel in register TestSel1Reg.
The signal at SIGIN is a digital Manchester coded signal according to the requirements of
the ISO/IEC 14443A with the subcarrier frequency of 847.5 kHz generated by the secure
IC.

12.7 Hardware support for FeliCa and NFC polling
12.7.1 Polling sequence functionality for initiator
1. Timer: The PN512 has a timer, which can be programmed in a way that it generates
an interrupt at the end of each timeslot, or if required an interrupt is generated at the
end of the last timeslot.
2. The receiver can be configured in a way to receive continuously. In this mode it can
receive any number of packets. The receiver is ready to receive the next packet
directly after the last packet has been received. This mode is active by setting the bit
RxMultiple in register RxModeReg to 1 and has to be stopped by software.
3. The internal UART adds one byte to the end of every received packet, before it is
transferred into the FIFO-buffer. This byte indicates if the received byte packet is
correct (see register ErrReg). The first byte of each packet contains the length byte of
the packet.
4. The length of one packet is 18 or 20 bytes (+ 1 byte Error-Info). The FIFO has a
length of 64 bytes. This means three packets can be stored in the FIFO at the same
time. If more than three packets are expected, the host controller has to empty the
FIFO, before the FIFO is filled completely. In case of a FIFO-overflow data is lost (See
bit BufferOvfl in register ErrorReg).
12.7.2 Polling sequence functionality for target
1. The host controller has to configure the PN512 with the correct polling response
parameters for the polling command.
2. To activate the automatic polling in Target mode, the AutoColl Command has to be
activated.
3. The PN512 receives the polling command send out by an initiator and answers with
the polling response. The timeslot is selected automatically (The timeslot itself is
randomly generated, but in the range 0 to TSN, which is defined by the Polling
command). The PN512 compares the system code, stored in byte 17 and 18 of the
Config Command with the system code received by the polling command of an
initiator. If the system code is equal, the PN512 answers according to the configured
polling response. The system code FF (hex) acts as a wildcard for the system code
bytes, i.e. a target of a system code 1234 (hex) answers to the polling command with
one of the following system codes 1234 (hex), 12FF (hex), FF34 (hex) or FFFF (hex).
If the system code does not match no answer is sent back by the PN512.
If a valid command is received by the PN512, which is not a Polling command, no
answer is sent back and the command AutoColl is stopped. The received packet is
stored in the FIFO.PN512 All information provided in this document is subject to legal disclaimers. © NXP B.V. 2013. All rights reserved.

DataLenMin in register FelNFC1Reg defines the minimum length of the accepted packet
length. This register is six bit long. Each bit represents a length of four bytes.
DataLenMax in register FelNFC2Reg defines the maximum length of the accepted
package. This register is six bit long. Each bit represents a length of four bytes. If set to
logic 1 this limit is ignored. If the length is not in the supposed range, the packet is not
transferred to the FIFO and receiving is kept active.
Example 1:
• DataLenMin = 4
– The length shall be greater or equal 16.
• DataLenMax = 5
– The length shall be smaller than 20. Valid area: 16, 17, 18, 19
Example 2:
• DataLenMin = 9
– The length shall be greater or equal 36.
• DataLenMax = 0
– The length shall be smaller than 256. Valid area: 36 to 255
12.7.4 CRC coprocessor
The following CRC coprocessor parameters can be configured:
• The CRC preset value can be either 0000h, 6363h, A671h or FFFFh depending on
the ModeReg register’s CRCPreset[1:0] bits setting
• The CRC polynomial for the 16-bit CRC is fixed to x16 + x12 + x5 + 1
• The CRCResultReg register indicates the result of the CRC calculation. This register
is split into two 8-bit registers representing the higher and lower bytes.
• The ModeReg register’s MSBFirst bit indicates that data will be loaded with the MSB
first.

13. FIFO buffer
An 8 64 bit FIFO buffer is used in the PN512. It buffers the input and output data stream
between the host and the PN512’s internal state machine. This makes it possible to
manage data streams up to 64 bytes long without the need to take timing constraints into
account.
13.1 Accessing the FIFO buffer
The FIFO buffer input and output data bus is connected to the FIFODataReg register.
Writing to this register stores one byte in the FIFO buffer and increments the internal FIFO
buffer write pointer. Reading from this register shows the FIFO buffer contents stored in
the FIFO buffer read pointer and decrements the FIFO buffer read pointer. The distance
between the write and read pointer can be obtained by reading the FIFOLevelReg
register.
When the microcontroller starts a command, the PN512 can, while the command is in
progress, access the FIFO buffer according to that command. Only one FIFO buffer has
been implemented which can be used for input and output. The microcontroller must
ensure that there are not any unintentional FIFO buffer accesses.
13.2 Controlling the FIFO buffer
The FIFO buffer pointers can be reset by setting FIFOLevelReg register’s FlushBuffer bit
to logic 1. Consequently, the FIFOLevel[6:0] bits are all set to logic 0 and the ErrorReg
register’s BufferOvfl bit is cleared. The bytes stored in the FIFO buffer are no longer
accessible allowing the FIFO buffer to be filled with another 64 bytes.
13.3 FIFO buffer status information
The host can get the following FIFO buffer status information:
• Number of bytes stored in the FIFO buffer: FIFOLevelReg register’s FIFOLevel[6:0]
• FIFO buffer almost full warning: Status1Reg register’s HiAlert bit
• FIFO buffer almost empty warning: Status1Reg register’s LoAlert bit
• FIFO buffer overflow warning: ErrorReg register’s BufferOvfl bit. The BufferOvfl bit
can only be cleared by setting the FIFOLevelReg register’s FlushBuffer bit.
The PN512 can generate an interrupt signal when:
• ComIEnReg register’s LoAlertIEn bit is set to logic 1. It activates pin IRQ when
Status1Reg register’s LoAlert bit changes to logic 1.
• ComIEnReg register’s HiAlertIEn bit is set to logic 1. It activates pin IRQ when
Status1Reg register’s HiAlert bit changes to logic 1.
If the maximum number of WaterLevel bytes (as set in the WaterLevelReg register) or less
are stored in the FIFO buffer, the HiAlert bit is set to logic 1. It is generated according to
Equation 3:

If the number of WaterLevel bytes (as set in the WaterLevelReg register) or less are
stored in the FIFO buffer, the LoAlert bit is set to logic 1. It is generated according to
Equation 4:
(4)
14. Interrupt request system
The PN512 indicates certain events by setting the Status1Reg register’s IRq bit and, if
activated, by pin IRQ. The signal on pin IRQ can be used to interrupt the host using its
interrupt handling capabilities. This allows the implementation of efficient host software.
14.1 Interrupt sources overview
Table 157 shows the available interrupt bits, the corresponding source and the condition
for its activation. The ComIrqReg register’s TimerIRq interrupt bit indicates an interrupt set
by the timer unit which is set when the timer decrements from 1 to 0.
The ComIrqReg register’s TxIRq bit indicates that the transmitter has finished. If the state
changes from sending data to transmitting the end of the frame pattern, the transmitter
unit automatically sets the interrupt bit. The CRC coprocessor sets the DivIrqReg
register’s CRCIRq bit after processing all the FIFO buffer data which is indicated by
CRCReady bit = 1.
The ComIrqReg register’s RxIRq bit indicates an interrupt when the end of the received
data is detected. The ComIrqReg register’s IdleIRq bit is set if a command finishes and
the Command[3:0] value in the CommandReg register changes to idle (see Table 158 on
page 101).
The ComIrqReg register’s HiAlertIRq bit is set to logic 1 when the Status1Reg register’s
HiAlert bit is set to logic 1 which means that the FIFO buffer has reached the level
indicated by the WaterLevel[5:0] bits.
The ComIrqReg register’s LoAlertIRq bit is set to logic 1 when the Status1Reg register’s
LoAlert bit is set to logic 1 which means that the FIFO buffer has reached the level
indicated by the WaterLevel[5:0] bits.
The ComIrqReg register’s ErrIRq bit indicates an error detected by the contactless UART
during send or receive. This is indicated when any bit is set to logic 1 in register ErrorReg.

15. Timer unit
A timer unit is implemented in the PN512. The external host controller may use this timer
to manage timing relevant tasks. The timer unit may be used in one of the following
configurations:
• Time-out counter
• Watch-dog counter
• Stop watch
• Programmable one-shot
• Periodical trigger
The timer unit can be used to measure the time interval between two events or to indicate
that a specific event occurred after a specific time. The timer can be triggered by events
which will be explained in the following, but the timer itself does not influence any internal
event (e.g. A time-out during data reception does not influence the reception process
automatically). Furthermore, several timer related bits are set and these bits can be used
to generate an interrupt.
Timer
The timer has an input clock of 13.56 MHz (derived from the 27.12 MHz quartz). The timer
consists of two stages: 1 prescaler and 1 counter.
The prescaler is a 12-bit counter. The reload value for TPrescaler can be defined between
0 and 4095 in register TModeReg and TPrescalerReg.
The reload value for the counter is defined by 16 bits in a range of 0 to 65535 in the
register TReloadReg.
The current value of the timer is indicated by the register TCounterValReg.
If the counter reaches 0 an interrupt will be generated automatically indicated by setting
the TimerIRq bit in the register CommonIRqReg. If enabled, this event can be indicated on
the IRQ line. The bit TimerIRq can be set and reset by the host controller. Depending on
the configuration the timer will stop at 0 or restart with the value from register
TReloadReg.
The status of the timer is indicated by bit TRunning in register Status1Reg.
The timer can be manually started by TStartNow in register ControlReg or manually
stopped by TStopNow in register ControlReg.
Furthermore the timer can be activated automatically by setting the bit TAuto in the
register TModeReg to fulfill dedicated protocol requirements automatically.
The time delay of a timer stage is the reload value +1.
The definition of total time is: t = ((TPrescaler*2+1)*TReload+1)/13.56MHz or if
TPrescaleEven bit is set: t = ((TPrescaler*2+2)*TReload+1)/13.56MHz
Maximum time: TPrescaler = 4095,TReloadVal = 65535
=> (2*4095 +2)*65536/13.56 MHz = 39.59 s

To indicate 25 us it is required to count 339 clock cycles. This means the value for
TPrescaler has to be set to TPrescaler = 169.The timer has now an input clock of 25 us.

16. Power reduction modes
16.1 Hard power-down
Hard power-down is enabled when pin NRSTPD is LOW. This turns off all internal current
sinks including the oscillator. All digital input buffers are separated from the input pins and
clamped internally (except pin NRSTPD). The output pins are frozen at either a HIGH or
LOW level.
16.2 Soft power-down mode
Soft Power-down mode is entered immediately after the CommandReg register’s
PowerDown bit is set to logic 1. All internal current sinks are switched off, including the
oscillator buffer. However, the digital input buffers are not separated from the input pins
and keep their functionality. The digital output pins do not change their state.
During soft power-down, all register values, the FIFO buffer content and the configuration
keep their current contents.
After setting the PowerDown bit to logic 0, it takes 1024 clocks until the Soft power-down
mode is exited indicated by the PowerDown bit. Setting it to logic 0 does not immediately
clear it. It is cleared automatically by the PN512 when Soft power-down mode is exited.
Remark: If the internal oscillator is used, you must take into account that it is supplied by
pin AVDD and it will take a certain time (tosc) until the oscillator is stable and the clock
cycles can be detected by the internal logic. It is recommended for the serial UART, to first
send the value 55h to the PN512. The oscillator must be stable for further access to the
registers. To ensure this, perform a read access to address 0 until the PN512 answers to
the last read command with the register content of address 0. This indicates that the
PN512 is ready.
16.3 Transmitter power-down mode
The Transmitter Power-down mode switches off the internal antenna drivers thereby,
turning off the RF field. Transmitter power-down mode is entered by setting either the
TxControlReg register’s Tx1RFEn bit or Tx2RFEn bit to logic 0.PN512 All information provided in this document is subject to legal disclaimers. © NXP B.V. 2013. All rights reserved.

17. Oscillator circuitry
The clock applied to the PN512 provides a time basis for the synchronous system’s
encoder and decoder. The stability of the clock frequency, therefore, is an important factor
for correct operation. To obtain optimum performance, clock jitter must be reduced as
much as possible. This is best achieved using the internal oscillator buffer with the
recommended circuitry.
If an external clock source is used, the clock signal must be applied to pin OSCIN. In this
case, special care must be taken with the clock duty cycle and clock jitter and the clock
quality must be verified.
18. Reset and oscillator start-up time
18.1 Reset timing requirements
The reset signal is filtered by a hysteresis circuit and a spike filter before it enters the
digital circuit. The spike filter rejects signals shorter than 10 ns. In order to perform a reset,
the signal must be LOW for at least 100 ns.
18.2 Oscillator start-up time
If the PN512 has been set to a Power-down mode or is powered by a VDDX supply, the
start-up time for the PN512 depends on the oscillator used and is shown in Figure 36.
The time (tstartup) is the start-up time of the crystal oscillator circuit. The crystal oscillator
start-up time is defined by the crystal.
The time (td) is the internal delay time of the PN512 when the clock signal is stable before
the PN512 can be addressed.
The delay time is calculated by:
(5)
The time (tosc) is the sum of td and tstartup.

19. PN512 command set
The PN512 operation is determined by a state machine capable of performing a set of
commands. A command is executed by writing a command code (see Table 158) to the
CommandReg register.
Arguments and/or data necessary to process a command are exchanged via the FIFO
buffer.
19.1 General description
The PN512 operation is determined by a state machine capable of performing a set of
commands. A command is executed by writing a command code (see Table 158) to the
CommandReg register.
Arguments and/or data necessary to process a command are exchanged via the FIFO
buffer.
19.2 General behavior
• Each command that needs a data bit stream (or data byte stream) as an input
immediately processes any data in the FIFO buffer. An exception to this rule is the
Transceive command. Using this command, transmission is started with the
BitFramingReg register’s StartSend bit.
• Each command that needs a certain number of arguments, starts processing only
when it has received the correct number of arguments from the FIFO buffer.
• The FIFO buffer is not automatically cleared when commands start. This makes it
possible to write command arguments and/or the data bytes to the FIFO buffer and
then start the command.
• Each command can be interrupted by the host writing a new command code to the
CommandReg register, for example, the Idle command.

19.3.1.2 Config command
To use the automatic MIFARE Anticollision, FeliCa Polling and NFCID3 the data used for
these transactions has to be stored internally. All the following data have to be written to
the FIFO in this order:
SENS_RES (2 bytes); in order byte 0, byte 1
NFCID1 (3 Bytes); in order byte 0, byte 1, byte 2; the first NFCID1 byte is fixed to 08h and
the check byte is calculated automatically.
SEL_RES (1 Byte)
polling response (2 bytes (shall be 01h, FEh) + 6 bytes NFCID2 + 8 bytes Pad + 2 bytes
system code)
NFCID3 (1 byte)
In total 25 bytes are transferred into an internal buffer.
The complete NFCID3 is 10 bytes long and consists of the 3 NFCID1 bytes, the 6 NFCID2
bytes and the one NFCID3 byte which are listed above.
To read out this configuration the command Config with an empty FIFO-buffer has to be
started. In this case the 25 bytes are transferred from the internal buffer to the FIFO.

The PN512 has to be configured after each power up, before using the automatic
Anticollision/Polling function (AutoColl command). During a hard power down (reset pin)
this configuration remains unchanged.
This command terminates automatically when finished and the active command is idle.
19.3.1.3 Generate RandomID
This command generates a 10-byte random number which is initially stored in the internal
buffer. This then overwrites the 10 bytes in the internal 25-byte buffer. This command
automatically terminates when finished and the PN512 returns to Idle mode.
19.3.1.4 CalcCRC
The FIFO buffer content is transferred to the CRC coprocessor and the CRC calculation is
started. The calculation result is stored in the CRCResultReg register. The CRC
calculation is not limited to a dedicated number of bytes. The calculation is not stopped
when the FIFO buffer is empty during the data stream. The next byte written to the FIFO
buffer is added to the calculation.
The CRC preset value is controlled by the ModeReg register’s CRCPreset[1:0] bits. The
value is loaded in to the CRC coprocessor when the command starts.
This command must be terminated by writing a command to the CommandReg register,
such as, the Idle command.
If the AutoTestReg register’s SelfTest[3:0] bits are set correctly, the PN512 enters Self
Test mode. Starting the CalcCRC command initiates a digital self test. The result of the
self test is written to the FIFO buffer.
19.3.1.5 Transmit
The FIFO buffer content is immediately transmitted after starting this command. Before
transmitting the FIFO buffer content, all relevant registers must be set for data
transmission.
This command automatically terminates when the FIFO buffer is empty. It can be
terminated by another command written to the CommandReg register.
19.3.1.6 NoCmdChange
This command does not influence any running command in the CommandReg register. It
can be used to manipulate any bit except the CommandReg register Command[3:0] bits,
for example, the RcvOff bit or the PowerDown bit.
19.3.1.7 Receive
The PN512 activates the receiver path and waits for a data stream to be received. The
correct settings must be chosen before starting this command.
This command automatically terminates when the data stream ends. This is indicated
either by the end of frame pattern or by the length byte depending on the selected frame
type and speed.
Remark: If the RxModeReg register’s RxMultiple bit is set to logic 1, the Receive
command will not automatically terminate. It must be terminated by starting another
command in the CommandReg register.PN512 All information provided in this document is subject to legal disclaimers. © NXP B.V. 2013. All rights reserved.

19.3.1.8 Transceive
This command continuously repeats the transmission of data from the FIFO buffer and the
reception of data from the RF field. The first action is transmit and after transmission the
command is changed to receive a data stream.
Each transmit process must be started by setting the BitFramingReg register’s StartSend
bit to logic 1. This command must be cleared by writing any command to the
CommandReg register.
Remark: If the RxModeReg register’s RxMultiple bit is set to logic 1, the Transceive
command never leaves the receive state because this state cannot be cancelled
automatically.
19.3.1.9 AutoColl
This command automatically handles the MIFARE activation and the FeliCa polling in the
Card Operation mode. The bit Initiator in the register ControlReg has to be set to logic 0
for correct operation. During this command also the mode detector is active if not
deactivated by setting the bit ModeDetOff in the ModeReg register. After the mode
detector detects a mode, all the mode dependent registers are set according to the
received data. In case of no external RF field the command resets the internal state
machine and returns to the initial state but it will not be terminated. When the command
terminates the transceive command gets active.
During protocol processing the IRQ bits are not supported. Only the last received frame
will serve the IRQ’s. The treatment of the TxCRCEn and RxCRCEn bits is different to the
protocol. During ISO/IEC 14443A activation the enable bits are defined by the command
AutoColl. The changes cannot be observed at the register TXModeReg and RXModeReg.
After the Transceive command is active, the value of the register bit is relevant.
The FIFO will also receive the two CRC check bytes of the last command even if they
already checked and correct, if the state machine (Anticollision and Select routine) has to
not been executed and 106 kbit is detected.
During Felica activation the register bit is always relevant and is not overruled by the
command settings. This command can be cleared by software by writing any other
command to the CommandReg register, e.g. the idle command. Writing the same content
again to the CommandReg register resets the state machine.PN512 All information provided in this document is subject to legal disclaimers. © NXP B.V. 2013. All rights reserved.

19.3.1.10 MFAuthent
This command manages MIFARE authentication to enable a secure communication to
any MIFARE Mini, MIFARE 1K and MIFARE 4K card. The following data is written to the
FIFO buffer before the command can be activated:
• Authentication command code (60h, 61h)
• Block address
• Sector key byte 0
• Sector key byte 1
• Sector key byte 2
• Sector key byte 3
• Sector key byte 4
• Sector key byte 5
• Card serial number byte 0
• Card serial number byte 1
• Card serial number byte 2
• Card serial number byte 3
In total 12 bytes are written to the FIFO.
Remark: When the MFAuthent command is active all access to the FIFO buffer is
blocked. However, if there is access to the FIFO buffer, the ErrorReg register’s WrErr bit is
set.
This command automatically terminates when the MIFARE card is authenticated and the
Status2Reg register’s MFCrypto1On bit is set to logic 1.
This command does not terminate automatically if the card does not answer, so the timer
must be initialized to automatic mode. In this case, in addition to the IdleIRq bit, the
TimerIRq bit can be used as the termination criteria. During authentication processing, the
RxIRq bit and TxIRq bit are blocked. The Crypto1On bit is only valid after termination of
the MFAuthent command, either after processing the protocol or writing Idle to the
CommandReg register.
If an error occurs during authentication, the ErrorReg register’s ProtocolErr bit is set to
logic 1 and the Status2Reg register’s Crypto1On bit is set to logic 0.PN512 All information provided in this document is subject to legal disclaimers. © NXP B.V. 2013. All rights reserved.

Each signal can be switched to pin AUX1 or AUX2 by setting SelAux1 or SelAux2 in the
register AnalogTestReg.
Note: The DAC has a current output, it is recommended to use a 1 k pull-down
resistance at pins AUX1/AUX2.
20.4 PRBS
Enables the PRBS9 or PRBS15 sequence according to ITU-TO150. To start the
transmission of the defined datastream the command send has to be activated. The
preamble/Sync byte/start bit/parity bit are generated automatically depending on the
selected mode.
Note: All relevant register to transmit data have to be configured before entering PRBS
mode according ITU-TO150.
21. Errata sheet
This data sheet is describing the functionality for version 2.0 and the industrial version.
This chapter lists all differences from version 1.0 to version 2.0:
The value of the version in Section 9.2.4.8 is set to80h.

Only the default setting for the prescaler (see Section 15 “Timer unit” on page 96): t =
((TPreScaler*2+1)*TReload+1)/13,56 MHz is supported. As such only the formula fTimer =
13,56 MHz/(2*PreScaler+1) is applicable for the TPrescalerHigh in Table 100 “Description
of TModeReg bits” on page 57 and TPrescalerLo in Table 101 “TPrescalerReg register
(address 2Bh); reset value: 00h, 00000000b” on page 58. As there is no option for the
prescaler available, also the TPrescalEven is not available Section 9.2.2.10 on page 45.

Especially when using time slot protocols, it is needed that the error flag is copied into the
status information of the frame. When using the RxMultiple feature (see Section 9.2.2.4
on page 39) within version 1.0 the protocol error flag is not included in the status
information for the frame. In addition the CRCOk is copied instead of the CRCErr. This
can be a problem in frames without length information e.g. ISO/IEC 14443-B.
The version 1.0 does not accept a Type B EOF if there is no 1 bit after the series of 0 bits,
as such the configuration within Section 9.2.2.15 “TypeBReg” on page 50 bit 4 for
RxEOFReq does not exist. In addition the IC only has the possibility to select the
minimum or maximum timings for SOF/EOF generation defined in ISO/IEC14443B. As
such the configuration possible in version 2.0 through the EOFSOFAdjust bit (see Section
9.2.4.7 “AutoTestReg” on page 64) does not exist and the configuration is limited to only
setting minimum and maximum length according ISO/IEC 14443-B, see Section 9.2.2.15
“TypeBReg” on page 50, bit 4.

NXP Semiconductors MMBZxVCL; MMBZxVDL series
Double ESD protection diodes for transient overvoltage suppression
8. Application information
The MMBZxVCL series and the MMBZxVDL series are designed for the protection of up
to two unidirectional data or signal lines from the damage caused by ESD and surge
pulses. The devices may be used on lines where the signal polarities are either positive or
negative with respect to ground. The devices provide a surge capability of 40 W per line
for a 10/1000 µs waveform.
Circuit board layout and protection device placement
Circuit board layout is critical for the suppression of ESD, Electrical Fast Transient (EFT)
and surge transients. The following guidelines are recommended:
1. Place the devices as close to the input terminal or connector as possible.
2. The path length between the device and the protected line should be minimized.
3. Keep parallel signal paths to a minimum.
4. Avoid running protected conductors in parallel with unprotected conductors.
5. Minimize all Printed-Circuit Board (PCB) conductive loops including power and
ground loops.
6. Minimize the length of the transient return path to ground.
7. Avoid using shared transient return paths to a common ground point.
8. Ground planes should be used whenever possible. For multilayer PCBs, use ground
vias.
9. Test information
9.1 Quality information
This product has been qualified in accordance with the Automotive Electronics Council
(AEC) standard Q101 - Stress test qualification for discrete semiconductors, and is
suitable for use in automotive applications.

Integrated 4-, 6- and 8-channel passive filter network
Due to the optimized silicon dice and package design, all channels in a single package
show a very good matching performance as the insertion loss for a channel at the
package side (e.g. channel 1 to channel 16) is nearly identical with the center channels
(e.g. channel 4 to channel 13).

NXP Semiconductors IP4251/52/53/54-TTL
Integrated 4-, 6- and 8-channel passive filter network
6.2 Selection
The selection of one of the filter devices has to be performed depending on the maximum
clock frequency, driver strength, capacitive load of the sink, and also the maximum
applicable rise and fall times.
6.2.1 SDHC and MMC memory interface
The Secure Digital High Capacity (SDHC) memory card interface standard specification
and the Multi Media Card (MMC) (JESD 84A43) standard specification recommend a rise
and fall time of 25 % to 62.5 % (62.5 % to 25 % respectively) of 3 ns or less for the input
signal of the receiving interface side.
Assuming a typical capacitance of about 20 pF for the SDHC memory card itself, and
approximately 4 pF to 7 pF for the Printed-Circuit Board (PCB) and the card holder,
IP4252CZ12-6-TTL (6 channels, Rs(ch) = 40 Ω, Cch = 12 pF at Vbias(DC) = 2.5 V) is a
matching selection to filter and protect all relevant interface pins such as CLK, CMD, and
DAT0 to DAT3/CD. Please refer to Figure 7 for a general example of the implementation
of the device in an SDHC card interface.
In case additional channels such as write-protect or a mechanical card-detection switch
are used, the IP4252CZ16-8-TTL (8 channels, Rs(ch) = 40 Ω, Cch = 12 pF at
Vbias(DC) = 2.5 V) offers two additional channels.IP4251_52_53_54-TTL All information provided in this document is subject to legal disclaimers. © NXP B.V. 2011. All rights reserved.
Product data sheet Rev. 2 — 5 May 2011 10 of 18
NXP Semiconductors IP4251/52/53/54-TTL
Integrated 4-, 6- and 8-channel passive filter network
The capacitance values specified for the signal channels of the MMC interface differ from
the SDHC specification. The MMC card-side interface is specified to have an intrinsic
capacitance of 12 pF to 18 pF and the total channel is limited according to the
specification to 30 pF only. Therefore, any filter device capacitance is limited to a
maximum of up to 18 pF, including the card holder and PCB traces.
Please refer to Figure 8 for a general example of the implementation of the IP4252 in an
MMC interface application.

NXP Semiconductors IP4251/52/53/54-TTL
Integrated 4-, 6- and 8-channel passive filter network
To generate SDHC and MMC-compliant digital signals, the driver strength should not
significantly undercut 8 mA.
6.2.2 LCD interfaces, medium-speed interfaces
For digital interfaces such as LCD interfaces running at clock speeds between 10 MHz
and 25 MHz or more, IP4251, IP4252 or IP4254 can be used depending on the sink load,
clock speed, driver strength and rise and fall time requirements. Also the minimum
EMI filter requirements may be a decision-making factor.
6.2.3 Keypad, low-speed interfaces
Especially for lower-speed interfaces such as keypads, low-speed serial interfaces
(e.g. Recommended Standard (RS) 232) and low-speed control signals,
IP4253 (Rs(ch) = 200 Ω, Cch = 30 pF at Vbias(DC) = 2.5 V) offers a very robust
ESD protection and strong suppression of unwanted frequencies (EMI filtering).

ATtiny2313
The AVR core combines a rich instruction set with 32 general purpose working registers. All the
32 registers are directly connected to the Arithmetic Logic Unit (ALU), allowing two independent
registers to be accessed in one single instruction executed in one clock cycle. The resulting
architecture is more code efficient while achieving throughputs up to ten times faster than conventional
CISC microcontrollers.
The ATtiny2313 provides the following features: 2K bytes of In-System Programmable Flash,
128 bytes EEPROM, 128 bytes SRAM, 18 general purpose I/O lines, 32 general purpose working
registers, a single-wire Interface for On-chip Debugging, two flexible Timer/Counters with
compare modes, internal and external interrupts, a serial programmable USART, Universal
Serial Interface with Start Condition Detector, a programmable Watchdog Timer with internal
Oscillator, and three software selectable power saving modes. The Idle mode stops the CPU
while allowing the SRAM, Timer/Counters, and interrupt system to continue functioning. The
Power-down mode saves the register contents but freezes the Oscillator, disabling all other chip
functions until the next interrupt or hardware reset. In Standby mode, the crystal/resonator Oscillator
is running while the rest of the device is sleeping. This allows very fast start-up combined
with low-power consumption.
The device is manufactured using Atmel’s high density non-volatile memory technology. The
On-chip ISP Flash allows the program memory to be reprogrammed In-System through an SPI
serial interface, or by a conventional non-volatile memory programmer. By combining an 8-bit
RISC CPU with In-System Self-Programmable Flash on a monolithic chip, the Atmel ATtiny2313
is a powerful microcontroller that provides a highly flexible and cost effective solution to many
embedded control applications.
The ATtiny2313 AVR is supported with a full suite of program and system development tools
including: C Compilers, Macro Assemblers, Program Debugger/Simulators, In-Circuit Emulators,
and Evaluation kits.5

Pin Descriptions
VCC Digital supply voltage.
GND Ground.
Port A (PA2..PA0) Port A is a 3-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The
Port A output buffers have symmetrical drive characteristics with both high sink and source
capability. As inputs, Port A pins that are externally pulled low will source current if the pull-up
resistors are activated. The Port A pins are tri-stated when a reset condition becomes active,
even if the clock is not running.

53.
Port B (PB7..PB0) Port B is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The
Port B output buffers have symmetrical drive characteristics with both high sink and source
capability. As inputs, Port B pins that are externally pulled low will source current if the pull-up
resistors are activated. The Port B pins are tri-stated when a reset condition becomes active,
even if the clock is not running.
Port B also serves the functions of various special features of the ATtiny2313 as listed on page

Port D (PD6..PD0) Port D is a 7-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The
Port D output buffers have symmetrical drive characteristics with both high sink and source
capability. As inputs, Port D pins that are externally pulled low will source current if the pull-up
resistors are activated. The Port D pins are tri-stated when a reset condition becomes active,
even if the clock is not running.
Port D also serves the functions of various special features of the ATtiny2313 as listed on page
56.
RESET Reset input. A low level on this pin for longer than the minimum pulse length will generate a
reset, even if the clock is not running. The minimum pulse length is given in Table 15 on page
34. Shorter pulses are not guaranteed to generate a reset. The Reset Input is an alternate function
for PA2 and dW.
XTAL1 Input to the inverting Oscillator amplifier and input to the internal clock operating circuit. XTAL1
is an alternate function for PA0.
XTAL2 Output from the inverting Oscillator amplifier. XTAL2 is an alternate function for PA1.6

AVR CPU Core
Introduction This section discusses the AVR core architecture in general. The main function of the CPU core
is to ensure correct program execution. The CPU must therefore be able to access memories,
perform calculations, control peripherals, and handle interrupts.
Architectural
Overview
Figure 3. Block Diagram of the AVR Architecture
In order to maximize performance and parallelism, the AVR uses a Harvard architecture – with
separate memories and buses for program and data. Instructions in the program memory are
executed with a single level pipelining. While one instruction is being executed, the next instruction
is pre-fetched from the program memory. This concept enables instructions to be executed
in every clock cycle. The program memory is In-System Reprogrammable Flash memory.
The fast-access Register File contains 32 x 8-bit general purpose working registers with a single
clock cycle access time. This allows single-cycle Arithmetic Logic Unit (ALU) operation. In a typical
ALU operation, two operands are output from the Register File, the operation is executed,
and the result is stored back in the Register File – in one clock cycle.

ATtiny2313
Six of the 32 registers can be used as three 16-bit indirect address register pointers for Data
Space addressing – enabling efficient address calculations. One of the these address pointers
can also be used as an address pointer for look up tables in Flash program memory. These
added function registers are the 16-bit X-, Y-, and Z-register, described later in this section.
The ALU supports arithmetic and logic operations between registers or between a constant and
a register. Single register operations can also be executed in the ALU. After an arithmetic operation,
the Status Register is updated to reflect information about the result of the operation.
Program flow is provided by conditional and unconditional jump and call instructions, able to
directly address the whole address space. Most AVR instructions have a single 16-bit word format.
Every program memory address contains a 16- or 32-bit instruction.
During interrupts and subroutine calls, the return address Program Counter (PC) is stored on the
Stack. The Stack is effectively allocated in the general data SRAM, and consequently the Stack
size is only limited by the total SRAM size and the usage of the SRAM. All user programs must
initialize the SP in the Reset routine (before subroutines or interrupts are executed). The Stack
Pointer (SP) is read/write accessible in the I/O space. The data SRAM can easily be accessed
through the five different addressing modes supported in the AVR architecture.
The memory spaces in the AVR architecture are all linear and regular memory maps.
A flexible interrupt module has its control registers in the I/O space with an additional Global
Interrupt Enable bit in the Status Register. All interrupts have a separate Interrupt Vector in the
Interrupt Vector table. The interrupts have priority in accordance with their Interrupt Vector position.
The lower the Interrupt Vector address, the higher the priority.
The I/O memory space contains 64 addresses for CPU peripheral functions as Control Registers,
and other I/O functions. The I/O Memory can be accessed directly, or as the Data Space
locations following those of the Register File, 0x20 - 0x5F.
ALU – Arithmetic
Logic Unit
The high-performance AVR ALU operates in direct connection with all the 32 general purpose
working registers. Within a single clock cycle, arithmetic operations between general purpose
registers or between a register and an immediate are executed. The ALU operations are divided
into three main categories – arithmetic, logical, and bit-functions. Some implementations of the
architecture also provide a powerful multiplier supporting both signed/unsigned multiplication
and fractional format. See the “Instruction Set” section for a detailed description.
Status Register The Status Register contains information about the result of the most recently executed arithmetic
instruction. This information can be used for altering program flow in order to perform
conditional operations. Note that the Status Register is updated after all ALU operations, as
specified in the Instruction Set Reference. This will in many cases remove the need for using the
dedicated compare instructions, resulting in faster and more compact code.
The Status Register is not automatically stored when entering an interrupt routine and restored
when returning from an interrupt. This must be handled by software.9
2543L–AVR–08/10
ATtiny2313
The AVR Status Register – SREG – is defined as:
• Bit 7 – I: Global Interrupt Enable
The Global Interrupt Enable bit must be set for the interrupts to be enabled. The individual interrupt
enable control is then performed in separate control registers. If the Global Interrupt Enable
Register is cleared, none of the interrupts are enabled independent of the individual interrupt
enable settings. The I-bit is cleared by hardware after an interrupt has occurred, and is set by
the RETI instruction to enable subsequent interrupts. The I-bit can also be set and cleared by
the application with the SEI and CLI instructions, as described in the instruction set reference.
• Bit 6 – T: Bit Copy Storage
The Bit Copy instructions BLD (Bit LoaD) and BST (Bit STore) use the T-bit as source or destination
for the operated bit. A bit from a register in the Register File can be copied into T by the
BST instruction, and a bit in T can be copied into a bit in a register in the Register File by the
BLD instruction.
• Bit 5 – H: Half Carry Flag
The Half Carry Flag H indicates a Half Carry in some arithmetic operations. Half Carry Is useful
in BCD arithmetic. See the “Instruction Set Description” for detailed information.
• Bit 4 – S: Sign Bit, S = N ⊕ V
The S-bit is always an exclusive or between the negative flag N and the Two’s Complement
Overflow Flag V. See the “Instruction Set Description” for detailed information.
• Bit 3 – V: Two’s Complement Overflow Flag
The Two’s Complement Overflow Flag V supports two’s complement arithmetics. See the
“Instruction Set Description” for detailed information.
• Bit 2 – N: Negative Flag
The Negative Flag N indicates a negative result in an arithmetic or logic operation. See the

General Purpose
Register File
The Register File is optimized for the AVR Enhanced RISC instruction set. In order to achieve
the required performance and flexibility, the following input/output schemes are supported by the
Register File:
• One 8-bit output operand and one 8-bit result input
• Two 8-bit output operands and one 8-bit result input
• Two 8-bit output operands and one 16-bit result input
• One 16-bit output operand and one 16-bit result input
Figure 4 shows the structure of the 32 general purpose working registers in the CPU.

Figure 4. AVR CPU General Purpose Working Registers
Most of the instructions operating on the Register File have direct access to all registers, and
most of them are single cycle instructions.
As shown in Figure 4, each register is also assigned a data memory address, mapping them
directly into the first 32 locations of the user Data Space. Although not being physically implemented
as SRAM locations, this memory organization provides great flexibility in access of the
registers, as the X-, Y- and Z-pointer registers can be set to index any register in the file.
The X-register, Yregister,
and Z-register
The registers R26..R31 have some added functions to their general purpose usage. These registers
are 16-bit address pointers for indirect addressing of the data space. The three indirect
address registers X, Y, and Z are defined as described in Figure 5.
Figure 5. The X-, Y-, and Z-registers
In the different addressing modes these address registers have functions as fixed displacement,
automatic increment, and automatic decrement (see the instruction set reference for details).

Stack Pointer The Stack is mainly used for storing temporary data, for storing local variables and for storing
return addresses after interrupts and subroutine calls. The Stack Pointer Register always points
to the top of the Stack. Note that the Stack is implemented as growing from higher memory locations
to lower memory locations. This implies that a Stack PUSH command decreases the Stack
Pointer.
The Stack Pointer points to the data SRAM Stack area where the Subroutine and Interrupt
Stacks are located. This Stack space in the data SRAM must be defined by the program before
any subroutine calls are executed or interrupts are enabled. The Stack Pointer must be set to
point above 0x60. The Stack Pointer is decremented by one when data is pushed onto the Stack
with the PUSH instruction, and it is decremented by two when the return address is pushed onto
the Stack with subroutine call or interrupt. The Stack Pointer is incremented by one when data is
popped from the Stack with the POP instruction, and it is incremented by two when data is
popped from the Stack with return from subroutine RET or return from interrupt RETI.
The AVR Stack Pointer is implemented as two 8-bit registers in the I/O space. The number of
bits actually used is implementation dependent. Note that the data space in some implementations
of the AVR architecture is so small that only SPL is needed. In this case, the SPH Register
will not be present.
Instruction
Execution Timing
This section describes the general access timing concepts for instruction execution. The AVR
CPU is driven by the CPU clock clkCPU, directly generated from the selected clock source for the
chip. No internal clock division is used.
Figure 6 shows the parallel instruction fetches and instruction executions enabled by the Harvard
architecture and the fast-access Register File concept. This is the basic pipelining concept
to obtain up to 1 MIPS per MHz with the corresponding unique results for functions per cost,
functions per clocks, and functions per power-unit.
Figure 6. The Parallel Instruction Fetches and Instruction Executions
Figure 7 shows the internal timing concept for the Register File. In a single clock cycle an ALU
operation using two register operands is executed, and the result is stored back to the destination
register.

Reset and
Interrupt Handling
The AVR provides several different interrupt sources. These interrupts and the separate Reset
Vector each have a separate program vector in the program memory space. All interrupts are
assigned individual enable bits which must be written logic one together with the Global Interrupt
Enable bit in the Status Register in order to enable the interrupt.
The lowest addresses in the program memory space are by default defined as the Reset and
Interrupt Vectors. The complete list of vectors is shown in “Interrupts” on page 44. The list also
determines the priority levels of the different interrupts. The lower the address the higher is the
priority level. RESET has the highest priority, and next is INT0 – the External Interrupt Request
0. Refer to “Interrupts” on page 44 for more information.
When an interrupt occurs, the Global Interrupt Enable I-bit is cleared and all interrupts are disabled.
The user software can write logic one to the I-bit to enable nested interrupts. All enabled
interrupts can then interrupt the current interrupt routine. The I-bit is automatically set when a
Return from Interrupt instruction – RETI – is executed.
There are basically two types of interrupts. The first type is triggered by an event that sets the
interrupt flag. For these interrupts, the Program Counter is vectored to the actual Interrupt Vector
in order to execute the interrupt handling routine, and hardware clears the corresponding interrupt
flag. Interrupt flags can also be cleared by writing a logic one to the flag bit position(s) to be
cleared. If an interrupt condition occurs while the corresponding interrupt enable bit is cleared,
the interrupt flag will be set and remembered until the interrupt is enabled, or the flag is cleared
by software. Similarly, if one or more interrupt conditions occur while the Global Interrupt Enable
bit is cleared, the corresponding interrupt flag(s) will be set and remembered until the Global
Interrupt Enable bit is set, and will then be executed by order of priority.
The second type of interrupts will trigger as long as the interrupt condition is present. These
interrupts do not necessarily have interrupt flags. If the interrupt condition disappears before the
interrupt is enabled, the interrupt will not be triggered.
When the AVR exits from an interrupt, it will always return to the main program and execute one
more instruction before any pending interrupt is served.
Note that the Status Register is not automatically stored when entering an interrupt routine, nor
restored when returning from an interrupt routine. This must be handled by software.
When using the CLI instruction to disable interrupts, the interrupts will be immediately disabled.
No interrupt will be executed after the CLI instruction, even if it occurs simultaneously with the

CLI instruction. The following example shows how this can be used to avoid interrupts during the
timed EEPROM write sequence..
When using the SEI instruction to enable interrupts, the instruction following SEI will be executed
before any pending interrupts, as shown in this example.
Interrupt Response
Time
The interrupt execution response for all the enabled AVR interrupts is four clock cycles minimum.
After four clock cycles the program vector address for the actual interrupt handling routine
is executed. During this four clock cycle period, the Program Counter is pushed onto the Stack.
The vector is normally a jump to the interrupt routine, and this jump takes three clock cycles. If
an interrupt occurs during execution of a multi-cycle instruction, this instruction is completed
before the interrupt is served. If an interrupt occurs when the MCU is in sleep mode, the interrupt
execution response time is increased by four clock cycles. This increase comes in addition to the
start-up time from the selected sleep mode.
A return from an interrupt handling routine takes four clock cycles. During these four clock
cycles, the Program Counter (two bytes) is popped back from the Stack, the Stack Pointer is
incremented by two, and the I-bit in SREG is set.

I/O-Ports
Introduction All AVR ports have true Read-Modify-Write functionality when used as general digital I/O ports.
This means that the direction of one port pin can be changed without unintentionally changing
the direction of any other pin with the SBI and CBI instructions. The same applies when changing
drive value (if configured as output) or enabling/disabling of pull-up resistors (if configured as
input). Each output buffer has symmetrical drive characteristics with both high sink and source
capability. The pin driver is strong enough to drive LED displays directly. All port pins have individually
selectable pull-up resistors with a supply-voltage invariant resistance. All I/O pins have
protection diodes to both VCC and Ground as indicated in Figure 21. Refer to “Electrical Characteristics”
on page 177 for a complete list of parameters.
Figure 21. I/O Pin Equivalent Schematic
All registers and bit references in this section are written in general form. A lower case “x” represents
the numbering letter for the port, and a lower case “n” represents the bit number. However,
when using the register or bit defines in a program, the precise form must be used. For example,
PORTB3 for bit no. 3 in Port B, here documented generally as PORTxn. The physical I/O Registers
and bit locations are listed in “Register Description for I/O-Ports” on page 58.
Three I/O memory address locations are allocated for each port, one each for the Data Register
– PORTx, Data Direction Register – DDRx, and the Port Input Pins – PINx. The Port Input Pins
I/O location is read only, while the Data Register and the Data Direction Register are read/write.
However, writing a logic one to a bit in the PINx Register, will result in a toggle in the corresponding
bit in the Data Register. In addition, the Pull-up Disable – PUD bit in MCUCR disables the
pull-up function for all pins in all ports when set.
Using the I/O port as General Digital I/O is described in “Ports as General Digital I/O” on page
47. Most port pins are multiplexed with alternate functions for the peripheral features on the
device. How each alternate function interferes with the port pin is described in “Alternate Port
Functions” on page 51. Refer to the individual module sections for a full description of the alternate
functions.
Note that enabling the alternate function of some of the port pins does not affect the use of the
other pins in the port as general digital I/O.

Ports as General
Digital I/O
The ports are bi-directional I/O ports with optional internal pull-ups. Figure 22 shows a functional
description of one I/O-port pin, here generically called Pxn.
Figure 22. General Digital I/O(1)
Note: 1. WRx, WPx, WDx, RRx, RPx, and RDx are common to all pins within the same port. clkI/O,
SLEEP, and PUD are common to all ports.
Configuring the Pin Each port pin consists of three register bits: DDxn, PORTxn, and PINxn. As shown in “Register
Description for I/O-Ports” on page 58, the DDxn bits are accessed at the DDRx I/O address, the
PORTxn bits at the PORTx I/O address, and the PINxn bits at the PINx I/O address.
The DDxn bit in the DDRx Register selects the direction of this pin. If DDxn is written logic one,
Pxn is configured as an output pin. If DDxn is written logic zero, Pxn is configured as an input
pin.
If PORTxn is written logic one when the pin is configured as an input pin, the pull-up resistor is
activated. To switch the pull-up resistor off, PORTxn has to be written logic zero or the pin has to
be configured as an output pin. The port pins are tri-stated when reset condition becomes active,
even if no clocks are running.
If PORTxn is written logic one when the pin is configured as an output pin, the port pin is driven
high (one). If PORTxn is written logic zero when the pin is configured as an output pin, the port
pin is driven low (zero).
Toggling the Pin Writing a logic one to PINxn toggles the value of PORTxn, independent on the value of DDRxn.
Note that the SBI instruction can be used to toggle one single bit in a port.

Switching Between
Input and Output
When switching between tri-state ({DDxn, PORTxn} = 0b00) and output high ({DDxn, PORTxn}
= 0b11), an intermediate state with either pull-up enabled {DDxn, PORTxn} = 0b01) or output
low ({DDxn, PORTxn} = 0b10) must occur. Normally, the pull-up enabled state is fully acceptable,
as a high-impedant environment will not notice the difference between a strong high driver
and a pull-up. If this is not the case, the PUD bit in the MCUCR Register can be set to disable all
pull-ups in all ports.
Switching between input with pull-up and output low generates the same problem. The user
must use either the tri-state ({DDxn, PORTxn} = 0b00) or the output high state ({DDxn, PORTxn}
= 0b11) as an intermediate step.
Table 22 summarizes the control signals for the pin value.
Reading the Pin Value Independent of the setting of Data Direction bit DDxn, the port pin can be read through the
PINxn Register bit. As shown in Figure 22, the PINxn Register bit and the preceding latch constitute
a synchronizer. This is needed to avoid metastability if the physical pin changes value near
the edge of the internal clock, but it also introduces a delay. Figure 23 shows a timing diagram of
the synchronization when reading an externally applied pin value. The maximum and minimum
propagation delays are denoted tpd,max and tpd,min respectively.

Consider the clock period starting shortly after the first falling edge of the system clock. The latch
is closed when the clock is low, and goes transparent when the clock is high, as indicated by the
shaded region of the “SYNC LATCH” signal. The signal value is latched when the system clock
goes low. It is clocked into the PINxn Register at the succeeding positive clock edge. As indicated
by the two arrows tpd,max and tpd,min, a single signal transition on the pin will be delayed
between ½ and 1½ system clock period depending upon the time of assertion.
When reading back a software assigned pin value, a nop instruction must be inserted as indicated
in Figure 24. The out instruction sets the “SYNC LATCH” signal at the positive edge of the
clock. In this case, the delay tpd through the synchronizer is 1 system clock period.

The following code example shows how to set port B pins 0 and 1 high, 2 and 3 low, and define
the port pins from 4 to 7 as input with pull-ups assigned to port pins 6 and 7. The resulting pin
values are read back again, but as previously discussed, a nop instruction is included to be able
to read back the value recently assigned to some of the pins.
Note: 1. For the assembly program, two temporary registers are used to minimize the time from pullups
are set on pins 0, 1, 6, and 7, until the direction bits are correctly set, defining bit 2 and 3
as low and redefining bits 0 and 1 as strong high drivers.
Digital Input Enable
and Sleep Modes
As shown in Figure 22, the digital input signal can be clamped to ground at the input of the
Schmitt Trigger. The signal denoted SLEEP in the figure, is set by the MCU Sleep Controller in
Power-down mode, and Standby mode to avoid high power consumption if some input signals
are left floating, or have an analog signal level close to VCC/2.
SLEEP is overridden for port pins enabled as external interrupt pins. If the external interrupt
request is not enabled, SLEEP is active also for these pins. SLEEP is also overridden by various
other alternate functions as described in “Alternate Port Functions” on page 51.
If a logic high level (“one”) is present on an asynchronous external interrupt pin configured as
“Interrupt on Rising Edge, Falling Edge, or Any Logic Change on Pin” while the external interrupt
is not enabled, the corresponding External Interrupt Flag will be set when resuming from the
above mentioned Sleep mode, as the clamping in these sleep mode produces the requested
logic change.

ldi r16,(1< CSn2:0 > 1). The number of system clock
cycles from when the timer is enabled to the first count occurs can be from 1 to N+1 system
clock cycles, where N equals the prescaler divisor (8, 64, 256, or 1024).
It is possible to use the prescaler reset for synchronizing the Timer/Counter to program execution.
However, care must be taken if the other Timer/Counter that shares the same prescaler
also uses prescaling. A prescaler reset will affect the prescaler period for all Timer/Counters it is
connected to.
External Clock Source An external clock source applied to the T1/T0 pin can be used as Timer/Counter clock
(clkT1/clkT0). The T1/T0 pin is sampled once every system clock cycle by the pin synchronization
logic. The synchronized (sampled) signal is then passed through the edge detector. Figure 38
shows a functional equivalent block diagram of the T1/T0 synchronization and edge detector
logic. The registers are clocked at the positive edge of the internal system clock (clkI/O). The latch
is transparent in the high period of the internal system clock.
The edge detector generates one clkT1/clkT0 pulse for each positive (CSn2:0 = 7) or negative
(CSn2:0 = 6) edge it detects.
Figure 38. T1/T0 Pin Sampling
The synchronization and edge detector logic introduces a delay of 2.5 to 3.5 system clock cycles
from an edge has been applied to the T1/T0 pin to the counter is updated.
Enabling and disabling of the clock input must be done when T1/T0 has been stable for at least
one system clock cycle, otherwise it is a risk that a false Timer/Counter clock pulse is generated.
Each half period of the external clock applied must be longer than one system clock cycle to
ensure correct sampling. The external clock must be guaranteed to have less than half the system
clock frequency (fExtClk < fclk_I/O/2) given a 50/50% duty cycle. Since the edge detector uses
sampling, the maximum frequency of an external clock it can detect is half the sampling freTn_sync

quency (Nyquist sampling theorem). However, due to variation of the system clock frequency
and duty cycle caused by Oscillator source (crystal, resonator, and capacitors) tolerances, it is
recommended that maximum frequency of an external clock source is less than fclk_I/O/2.5.
An external clock source can not be prescaled.

16-bit
Timer/Counter1
The 16-bit Timer/Counter unit allows accurate program execution timing (event management),
wave generation, and signal timing measurement. The main features are:
• True 16-bit Design (i.e., Allows 16-bit PWM)
• Two independent Output Compare Units
• Double Buffered Output Compare Registers
• One Input Capture Unit
• Input Capture Noise Canceler
• Clear Timer on Compare Match (Auto Reload)
• Glitch-free, Phase Correct Pulse Width Modulator (PWM)
• Variable PWM Period
• Frequency Generator
• External Event Counter
• Four independent interrupt Sources (TOV1, OCF1A, OCF1B, and ICF1)
Overview Most register and bit references in this section are written in general form. A lower case “n”
replaces the Timer/Counter number, and a lower case “x” replaces the Output Compare unit
channel. However, when using the register or bit defines in a program, the precise form must be
used, i.e., TCNT1 for accessing Timer/Counter1 counter value and so on.
A simplified block diagram of the 16-bit Timer/Counter is shown in Figure 40. For the actual
placement of I/O pins, refer to “Pinout ATtiny2313” on page 2. CPU accessible I/O Registers,
including I/O bits and I/O pins, are shown in bold. The device-specific I/O Register and bit locations
are listed in the “16-bit Timer/Counter Register Description” on page 104.

Registers The Timer/Counter (TCNT1), Output Compare Registers (OCR1A/B), and Input Capture Register
(ICR1) are all 16-bit registers. Special procedures must be followed when accessing the 16-
bit registers. These procedures are described in the section “Accessing 16-bit Registers” on
page 84. The Timer/Counter Control Registers (TCCR1A/B) are 8-bit registers and have no CPU
access restrictions. Interrupt requests (abbreviated to Int.Req. in the figure) signals are all visible
in the Timer Interrupt Flag Register (TIFR). All interrupts are individually masked with the Timer
Interrupt Mask Register (TIMSK). TIFR and TIMSK are not shown in the figure.
The Timer/Counter can be clocked internally, via the prescaler, or by an external clock source on
the T1 pin. The Clock Select logic block controls which clock source and edge the Timer/Counter
uses to increment (or decrement) its value. The Timer/Counter is inactive when no clock source
is selected. The output from the Clock Select logic is referred to as the timer clock (clkT1).
The double buffered Output Compare Registers (OCR1A/B) are compared with the Timer/Counter
value at all time. The result of the compare can be used by the Waveform Generator to
generate a PWM or variable frequency output on the Output Compare pin (OC1A/B). See “Output
Compare Units” on page 90.. The compare match event will also set the Compare Match
Flag (OCF1A/B) which can be used to generate an Output Compare interrupt request.
The Input Capture Register can capture the Timer/Counter value at a given external (edge triggered)
event on either the Input Capture pin (ICP1) or on the Analog Comparator pins (See
“Analog Comparator” on page 149.) The Input Capture unit includes a digital filtering unit (Noise
Canceler) for reducing the chance of capturing noise spikes.
The TOP value, or maximum Timer/Counter value, can in some modes of operation be defined
by either the OCR1A Register, the ICR1 Register, or by a set of fixed values. When using
OCR1A as TOP value in a PWM mode, the OCR1A Register can not be used for generating a
PWM output. However, the TOP value will in this case be double buffered allowing the TOP
value to be changed in run time. If a fixed TOP value is required, the ICR1 Register can be used
as an alternative, freeing the OCR1A to be used as PWM output.
Definitions The following definitions are used extensively throughout the section:
Compatibility The 16-bit Timer/Counter has been updated and improved from previous versions of the 16-bit
AVR Timer/Counter. This 16-bit Timer/Counter is fully compatible with the earlier version
regarding:
• All 16-bit Timer/Counter related I/O Register address locations, including Timer Interrupt
Registers.
• Bit locations inside all 16-bit Timer/Counter Registers, including Timer Interrupt Registers.
• Interrupt Vectors.
The following control bits have changed name, but have same functionality and register location:
• PWM10 is changed to WGM10.
• PWM11 is changed to WGM11.
• CTC1 is changed to WGM12.
Table 42. Definitions
BOTTOM The counter reaches the BOTTOM when it becomes 0x0000.
MAX The counter reaches its MAXimum when it becomes 0xFFFF (decimal 65535).
TOP
The counter reaches the TOP when it becomes equal to the highest value in the
count sequence. The TOP value can be assigned to be one of the fixed values:
0x00FF, 0x01FF, or 0x03FF, or to the value stored in the OCR1A or ICR1 Register.
The assignment is dependent of the mode of operation.84
2543L–AVR–08/10
ATtiny2313
The following bits are added to the 16-bit Timer/Counter Control Registers:
• FOC1A and FOC1B are added to TCCR1A.
• WGM13 is added to TCCR1B.
The 16-bit Timer/Counter has improvements that will affect the compatibility in some special
cases.
Accessing 16-bit
Registers
The TCNT1, OCR1A/B, and ICR1 are 16-bit registers that can be accessed by the AVR CPU via
the 8-bit data bus. The 16-bit register must be byte accessed using two read or write operations.
Each 16-bit timer has a single 8-bit register for temporary storing of the high byte of the 16-bit
access. The same temporary register is shared between all 16-bit registers within each 16-bit
timer. Accessing the low byte triggers the 16-bit read or write operation. When the low byte of a
16-bit register is written by the CPU, the high byte stored in the temporary register, and the low
byte written are both copied into the 16-bit register in the same clock cycle. When the low byte of
a 16-bit register is read by the CPU, the high byte of the 16-bit register is copied into the temporary
register in the same clock cycle as the low byte is read.
Not all 16-bit accesses uses the temporary register for the high byte. Reading the OCR1A/B 16-
bit registers does not involve using the temporary register.
To do a 16-bit write, the high byte must be written before the low byte. For a 16-bit read, the low
byte must be read before the high byte.
The following code examples show how to access the 16-bit timer registers assuming that no
interrupts updates the temporary register. The same principle can be used directly for accessing
the OCR1A/B and ICR1 Registers. Note that when using “C”, the compiler handles the 16-bit
access.85

For I/O Registers located in extended I/O map, “IN”, “OUT”, “SBIS”, “SBIC”, “CBI”, and “SBI”
instructions must be replaced with instructions that allow access to extended I/O. Typically
“LDS” and “STS” combined with “SBRS”, “SBRC”, “SBR”, and “CBR”.
The assembly code example returns the TCNT1 value in the r17:r16 register pair.
It is important to notice that accessing 16-bit registers are atomic operations. If an interrupt
occurs between the two instructions accessing the 16-bit register, and the interrupt code
updates the temporary register by accessing the same or any other of the 16-bit timer registers,
then the result of the access outside the interrupt will be corrupted. Therefore, when both the
main code and the interrupt code update the temporary register, the main code must disable the
interrupts during the 16-bit access.

Timer/Counter
Clock Sources
The Timer/Counter can be clocked by an internal or an external clock source. The clock source
is selected by the Clock Select logic which is controlled by the Clock Select (CS12:0) bits
located in the Timer/Counter control Register B (TCCR1B). For details on clock sources and
prescaler, see “Timer/Counter0 and Timer/Counter1 Prescalers” on page 80.
Counter Unit The main part of the 16-bit Timer/Counter is the programmable 16-bit bi-directional counter unit.
Figure 41 shows a block diagram of the counter and its surroundings.
Figure 41. Counter Unit Block Diagram
Signal description (internal signals):
Count Increment or decrement TCNT1 by 1.
Direction Select between increment and decrement.
Clear Clear TCNT1 (set all bits to zero).
clkT1 Timer/Counter clock.
TOP Signalize that TCNT1 has reached maximum value.
BOTTOM Signalize that TCNT1 has reached minimum value (zero).
The 16-bit counter is mapped into two 8-bit I/O memory locations: Counter High (TCNT1H) containing
the upper eight bits of the counter, and Counter Low (TCNT1L) containing the lower eight
bits. The TCNT1H Register can only be indirectly accessed by the CPU. When the CPU does an
access to the TCNT1H I/O location, the CPU accesses the high byte temporary register (TEMP).
The temporary register is updated with the TCNT1H value when the TCNT1L is read, and
TCNT1H is updated with the temporary register value when TCNT1L is written. This allows the
CPU to read or write the entire 16-bit counter value within one clock cycle via the 8-bit data bus.
It is important to notice that there are special cases of writing to the TCNT1 Register when the
counter is counting that will give unpredictable results. The special cases are described in the
sections where they are of importance.
Depending on the mode of operation used, the counter is cleared, incremented, or decremented
at each timer clock (clkT1). The clkT1 can be generated from an external or internal clock source,
selected by the Clock Select bits (CS12:0). When no clock source is selected (CS12:0 = 0) the
timer is stopped. However, the TCNT1 value can be accessed by the CPU, independent of
whether clkT1 is present or not. A CPU write overrides (has priority over) all counter clear or
count operations.
The counting sequence is determined by the setting of the Waveform Generation mode bits
(WGM13:0) located in the Timer/Counter Control Registers A and B (TCCR1A and TCCR1B).
There are close connections between how the counter behaves (counts) and how waveforms
are generated on the Output Compare outputs OC1x. For more details about advanced counting
sequences and waveform generation, see “Modes of Operation” on page 94.

The Timer/Counter Overflow Flag (TOV1) is set according to the mode of operation selected by
the WGM13:0 bits. TOV1 can be used for generating a CPU interrupt.
Input Capture Unit The Timer/Counter incorporates an Input Capture unit that can capture external events and give
them a time-stamp indicating time of occurrence. The external signal indicating an event, or multiple
events, can be applied via the ICP1 pin or alternatively, via the analog-comparator unit. The
time-stamps can then be used to calculate frequency, duty-cycle, and other features of the signal
applied. Alternatively the time-stamps can be used for creating a log of the events.
The Input Capture unit is illustrated by the block diagram shown in Figure 42. The elements of
the block diagram that are not directly a part of the Input Capture unit are gray shaded. The
small “n” in register and bit names indicates the Timer/Counter number.
Figure 42. Input Capture Unit Block Diagram
When a change of the logic level (an event) occurs on the Input Capture pin (ICP1), alternatively
on the Analog Comparator output (ACO), and this change confirms to the setting of the edge
detector, a capture will be triggered. When a capture is triggered, the 16-bit value of the counter
(TCNT1) is written to the Input Capture Register (ICR1). The Input Capture Flag (ICF1) is set at
the same system clock as the TCNT1 value is copied into ICR1 Register. If enabled (ICIE1 = 1),
the Input Capture Flag generates an Input Capture interrupt. The ICF1 flag is automatically
cleared when the interrupt is executed. Alternatively the ICF1 flag can be cleared by software by
writing a logical one to its I/O bit location.
Reading the 16-bit value in the Input Capture Register (ICR1) is done by first reading the low
byte (ICR1L) and then the high byte (ICR1H). When the low byte is read the high byte is copied
into the high byte temporary register (TEMP). When the CPU reads the ICR1H I/O location it will
access the TEMP Register.
The ICR1 Register can only be written when using a Waveform Generation mode that utilizes
the ICR1 Register for defining the counter’s TOP value. In these cases the Waveform Generation
mode (WGM13:0) bits must be set before the TOP value can be written to the ICR1
Register. When writing the ICR1 Register the high byte must be written to the ICR1H I/O location
before the low byte is written to ICR1L.

on page 84.
Input Capture Trigger
Source
The main trigger source for the Input Capture unit is the Input Capture pin (ICP1).
Timer/Counter1 can alternatively use the Analog Comparator output as trigger source for the
Input Capture unit. The Analog Comparator is selected as trigger source by setting the Analog
Comparator Input Capture (ACIC) bit in the Analog Comparator Control and Status Register
(ACSR). Be aware that changing trigger source can trigger a capture. The Input Capture Flag
must therefore be cleared after the change.
Both the Input Capture pin (ICP1) and the Analog Comparator output (ACO) inputs are sampled
using the same technique as for the T1 pin (Figure 38 on page 80). The edge detector is also
identical. However, when the noise canceler is enabled, additional logic is inserted before the
edge detector, which increases the delay by four system clock cycles. Note that the input of the
noise canceler and edge detector is always enabled unless the Timer/Counter is set in a Waveform
Generation mode that uses ICR1 to define TOP.
An Input Capture can be triggered by software by controlling the port of the ICP1 pin.
Noise Canceler The noise canceler improves noise immunity by using a simple digital filtering scheme. The
noise canceler input is monitored over four samples, and all four must be equal for changing the
output that in turn is used by the edge detector.
The noise canceler is enabled by setting the Input Capture Noise Canceler (ICNC1) bit in
Timer/Counter Control Register B (TCCR1B). When enabled the noise canceler introduces additional
four system clock cycles of delay from a change applied to the input, to the update of the
ICR1 Register. The noise canceler uses the system clock and is therefore not affected by the
prescaler.
Using the Input
Capture Unit
The main challenge when using the Input Capture unit is to assign enough processor capacity
for handling the incoming events. The time between two events is critical. If the processor has
not read the captured value in the ICR1 Register before the next event occurs, the ICR1 will be
overwritten with a new value. In this case the result of the capture will be incorrect.
When using the Input Capture interrupt, the ICR1 Register should be read as early in the interrupt
handler routine as possible. Even though the Input Capture interrupt has relatively high
priority, the maximum interrupt response time is dependent on the maximum number of clock
cycles it takes to handle any of the other interrupt requests.
Using the Input Capture unit in any mode of operation when the TOP value (resolution) is
actively changed during operation, is not recommended.
Measurement of an external signal’s duty cycle requires that the trigger edge is changed after
each capture. Changing the edge sensing must be done as early as possible after the ICR1
Register has been read. After a change of the edge, the Input Capture Flag (ICF1) must be
cleared by software (writing a logical one to the I/O bit location). For measuring frequency only,
the clearing of the ICF1 flag is not required (if an interrupt handler is used).
Output Compare
Units
The 16-bit comparator continuously compares TCNT1 with the Output Compare Register
(OCR1x). If TCNT equals OCR1x the comparator signals a match. A match will set the Output
Compare Flag (OCF1x) at the next timer clock cycle. If enabled (OCIE1x = 1), the Output Compare
Flag generates an Output Compare interrupt. The OCF1x flag is automatically cleared
when the interrupt is executed. Alternatively the OCF1x flag can be cleared by software by writing
a logical one to its I/O bit location. The Waveform Generator uses the match signal to
generate an output according to operating mode set by the Waveform Generation mode
(WGM13:0) bits and Compare Output mode (COM1x1:0) bits. The TOP and BOTTOM signals91
2543L–AVR–08/10
ATtiny2313
are used by the Waveform Generator for handling the special cases of the extreme values in
some modes of operation (See “Modes of Operation” on page 94.)
A special feature of Output Compare unit A allows it to define the Timer/Counter TOP value (i.e.,
counter resolution). In addition to the counter resolution, the TOP value defines the period time
for waveforms generated by the Waveform Generator.
Figure 43 shows a block diagram of the Output Compare unit. The small “n” in the register and
bit names indicates the device number (n = 1 for Timer/Counter 1), and the “x” indicates Output
Compare unit (A/B). The elements of the block diagram that are not directly a part of the Output
Compare unit are gray shaded.
Figure 43. Output Compare Unit, Block Diagram
The OCR1x Register is double buffered when using any of the twelve Pulse Width Modulation
(PWM) modes. For the Normal and Clear Timer on Compare (CTC) modes of operation, the
double buffering is disabled. The double buffering synchronizes the update of the OCR1x Compare
Register to either TOP or BOTTOM of the counting sequence. The synchronization
prevents the occurrence of odd-length, non-symmetrical PWM pulses, thereby making the output
glitch-free.
The OCR1x Register access may seem complex, but this is not case. When the double buffering
is enabled, the CPU has access to the OCR1x Buffer Register, and if double buffering is disabled
the CPU will access the OCR1x directly. The content of the OCR1x (Buffer or Compare)
Register is only changed by a write operation (the Timer/Counter does not update this register
automatically as the TCNT1 and ICR1 Register). Therefore OCR1x is not read via the high byte
temporary register (TEMP). However, it is a good practice to read the low byte first as when
accessing other 16-bit registers. Writing the OCR1x Registers must be done via the TEMP Register
since the compare of all 16 bits is done continuously. The high byte (OCR1xH) has to be
written first. When the high byte I/O location is written by the CPU, the TEMP Register will be
updated by the value written. Then when the low byte (OCR1xL) is written to the lower eight bits,
the high byte will be copied into the upper 8-bits of either the OCR1x buffer or OCR1x Compare
Register in the same system clock cycle.

Force Output
Compare
In non-PWM Waveform Generation modes, the match output of the comparator can be forced by
writing a one to the Force Output Compare (FOC1x) bit. Forcing compare match will not set the
OCF1x flag or reload/clear the timer, but the OC1x pin will be updated as if a real compare
match had occurred (the COM11:0 bits settings define whether the OC1x pin is set, cleared or
toggled).
Compare Match
Blocking by TCNT1
Write
All CPU writes to the TCNT1 Register will block any compare match that occurs in the next timer
clock cycle, even when the timer is stopped. This feature allows OCR1x to be initialized to the
same value as TCNT1 without triggering an interrupt when the Timer/Counter clock is enabled.
Using the Output
Compare Unit
Since writing TCNT1 in any mode of operation will block all compare matches for one timer clock
cycle, there are risks involved when changing TCNT1 when using any of the Output Compare
channels, independent of whether the Timer/Counter is running or not. If the value written to
TCNT1 equals the OCR1x value, the compare match will be missed, resulting in incorrect waveform
generation. Do not write the TCNT1 equal to TOP in PWM modes with variable TOP
values. The compare match for the TOP will be ignored and the counter will continue to 0xFFFF.
Similarly, do not write the TCNT1 value equal to BOTTOM when the counter is downcounting.
The setup of the OC1x should be performed before setting the Data Direction Register for the
port pin to output. The easiest way of setting the OC1x value is to use the Force Output Compare
(FOC1x) strobe bits in Normal mode. The OC1x Register keeps its value even when
changing between Waveform Generation modes.
Be aware that the COM1x1:0 bits are not double buffered together with the compare value.
Changing the COM1x1:0 bits will take effect immediately.93
2543L–AVR–08/10
ATtiny2313
Compare Match
Output Unit
The Compare Output mode (COM1x1:0) bits have two functions. The Waveform Generator uses
the COM1x1:0 bits for defining the Output Compare (OC1x) state at the next compare match.
Secondly the COM1x1:0 bits control the OC1x pin output source. Figure 44 shows a simplified
schematic of the logic affected by the COM1x1:0 bit setting. The I/O Registers, I/O bits, and I/O
pins in the figure are shown in bold. Only the parts of the general I/O port control registers (DDR
and PORT) that are affected by the COM1x1:0 bits are shown. When referring to the OC1x
state, the reference is for the internal OC1x Register, not the OC1x pin. If a system reset occur,
the OC1x Register is reset to “0”.
Figure 44. Compare Match Output Unit, Schematic
The general I/O port function is overridden by the Output Compare (OC1x) from the Waveform
Generator if either of the COM1x1:0 bits are set. However, the OC1x pin direction (input or output)
is still controlled by the Data Direction Register (DDR) for the port pin. The Data Direction
Register bit for the OC1x pin (DDR_OC1x) must be set as output before the OC1x value is visible
on the pin. The port override function is generally independent of the Waveform Generation
mode, but there are some exceptions. Refer to Table 43, Table 44 and Table 45 for details.
The design of the Output Compare pin logic allows initialization of the OC1x state before the output
is enabled. Note that some COM1x1:0 bit settings are reserved for certain modes of
operation. See “16-bit Timer/Counter Register Description” on page 104.
The COM1x1:0 bits have no effect on the Input Capture unit.

Compare Output Mode
and Waveform
Generation
The Waveform Generator uses the COM1x1:0 bits differently in normal, CTC, and PWM modes.
For all modes, setting the COM1x1:0 = 0 tells the Waveform Generator that no action on the
OC1x Register is to be performed on the next compare match. For compare output actions in the
non-PWM modes refer to Table 43 on page 104. For fast PWM mode refer to Table 44 on page
104, and for phase correct and phase and frequency correct PWM refer to Table 45 on page
105.
A change of the COM1x1:0 bits state will have effect at the first compare match after the bits are
written. For non-PWM modes, the action can be forced to have immediate effect by using the
FOC1x strobe bits.
Modes of
Operation
The mode of operation, i.e., the behavior of the Timer/Counter and the Output Compare pins, is
defined by the combination of the Waveform Generation mode (WGM13:0) and Compare Output
mode (COM1x1:0) bits. The Compare Output mode bits do not affect the counting sequence,
while the Waveform Generation mode bits do. The COM1x1:0 bits control whether the PWM output
generated should be inverted or not (inverted or non-inverted PWM). For non-PWM modes
the COM1x1:0 bits control whether the output should be set, cleared or toggle at a compare
match (See “Compare Match Output Unit” on page 93.)
For detailed timing information refer to “Timer/Counter Timing Diagrams” on page 102.
Normal Mode The simplest mode of operation is the Normal mode (WGM13:0 = 0). In this mode the counting
direction is always up (incrementing), and no counter clear is performed. The counter simply
overruns when it passes its maximum 16-bit value (MAX = 0xFFFF) and then restarts from the
BOTTOM (0x0000). In normal operation the Timer/Counter Overflow Flag (TOV1) will be set in
the same timer clock cycle as the TCNT1 becomes zero. The TOV1 flag in this case behaves
like a 17th bit, except that it is only set, not cleared. However, combined with the timer overflow
interrupt that automatically clears the TOV1 flag, the timer resolution can be increased by software.
There are no special cases to consider in the Normal mode, a new counter value can be
written anytime.
The Input Capture unit is easy to use in Normal mode. However, observe that the maximum
interval between the external events must not exceed the resolution of the counter. If the interval
between events are too long, the timer overflow interrupt or the prescaler must be used to
extend the resolution for the capture unit.
The Output Compare units can be used to generate interrupts at some given time. Using the
Output Compare to generate waveforms in Normal mode is not recommended, since this will
occupy too much of the CPU time.
Clear Timer on
Compare Match (CTC)
Mode
In Clear Timer on Compare or CTC mode (WGM13:0 = 4 or 12), the OCR1A or ICR1 Register
are used to manipulate the counter resolution. In CTC mode the counter is cleared to zero when
the counter value (TCNT1) matches either the OCR1A (WGM13:0 = 4) or the ICR1 (WGM13:0 =
12). The OCR1A or ICR1 define the top value for the counter, hence also its resolution. This
mode allows greater control of the compare match output frequency. It also simplifies the operation
of counting external events.
The timing diagram for the CTC mode is shown in Figure 45 on page 95. The counter value
(TCNT1) increases until a compare match occurs with either OCR1A or ICR1, and then counter
(TCNT1) is cleared.95
2543L–AVR–08/10
ATtiny2313
Figure 45. CTC Mode, Timing Diagram
An interrupt can be generated at each time the counter value reaches the TOP value by either
using the OCF1A or ICF1 flag according to the register used to define the TOP value. If the interrupt
is enabled, the interrupt handler routine can be used for updating the TOP value. However,
changing the TOP to a value close to BOTTOM when the counter is running with none or a low
prescaler value must be done with care since the CTC mode does not have the double buffering
feature. If the new value written to OCR1A or ICR1 is lower than the current value of TCNT1, the
counter will miss the compare match. The counter will then have to count to its maximum value
(0xFFFF) and wrap around starting at 0x0000 before the compare match can occur. In many
cases this feature is not desirable. An alternative will then be to use the fast PWM mode using
OCR1A for defining TOP (WGM13:0 = 15) since the OCR1A then will be double buffered.
For generating a waveform output in CTC mode, the OCFA output can be set to toggle its logical
level on each compare match by setting the Compare Output mode bits to toggle mode
(COM1A1:0 = 1). The OCF1A value will not be visible on the port pin unless the data direction
for the pin is set to output (DDR_OCF1A = 1). The waveform generated will have a maximum
frequency of fOC1A = fclk_I/O/2 when OCR1A is set to zero (0x0000). The waveform frequency is
defined by the following equation:
The N variable represents the prescaler factor (1, 8, 64, 256, or 1024).
As for the Normal mode of operation, the TOV1 flag is set in the same timer clock cycle that the
counter counts from MAX to 0x0000.

Fast PWM Mode The fast Pulse Width Modulation or fast PWM mode (WGM13:0 = 5, 6, 7, 14, or 15) provides a
high frequency PWM waveform generation option. The fast PWM differs from the other PWM
options by its single-slope operation. The counter counts from BOTTOM to TOP then restarts
from BOTTOM. In non-inverting Compare Output mode, the Output Compare (OC1x) is set on
the compare match between TCNT1 and OCR1x, and cleared at TOP. In inverting Compare
Output mode output is cleared on compare match and set at TOP. Due to the single-slope operation,
the operating frequency of the fast PWM mode can be twice as high as the phase correct
and phase and frequency correct PWM modes that use dual-slope operation. This high frequency
makes the fast PWM mode well suited for power regulation, rectification, and DAC
applications. High frequency allows physically small sized external components (coils, capacitors),
hence reduces total system cost.
The PWM resolution for fast PWM can be fixed to 8-, 9-, or 10-bit, or defined by either ICR1 or
OCR1A. The minimum resolution allowed is 2-bit (ICR1 or OCR1A set to 0x0003), and the maximum
resolution is 16-bit (ICR1 or OCR1A set to MAX). The PWM resolution in bits can be
calculated by using the following equation:
In fast PWM mode the counter is incremented until the counter value matches either one of the
fixed values 0x00FF, 0x01FF, or 0x03FF (WGM13:0 = 5, 6, or 7), the value in ICR1 (WGM13:0 =
14), or the value in OCR1A (WGM13:0 = 15). The counter is then cleared at the following timer
clock cycle. The timing diagram for the fast PWM mode is shown in Figure 46. The figure shows
fast PWM mode when OCR1A or ICR1 is used to define TOP. The TCNT1 value is in the timing
diagram shown as a histogram for illustrating the single-slope operation. The diagram includes
non-inverted and inverted PWM outputs. The small horizontal line marks on the TCNT1 slopes
represent compare matches between OCR1x and TCNT1. The OC1x interrupt flag will be set
when a compare match occurs.
Figure 46. Fast PWM Mode, Timing Diagram
The Timer/Counter Overflow Flag (TOV1) is set each time the counter reaches TOP. In addition
the OCF1A or ICF1 flag is set at the same timer clock cycle as TOV1 is set when either OCR1A
or ICR1 is used for defining the TOP value. If one of the interrupts are enabled, the interrupt handler
routine can be used for updating the TOP and compare values.
When changing the TOP value the program must ensure that the new TOP value is higher or
equal to the value of all of the Compare Registers. If the TOP value is lower than any of the
Compare Registers, a compare match will never occur between the TCNT1 and the OCR1x.

Note that when using fixed TOP values the unused bits are masked to zero when any of the
OCR1x Registers are written.
The procedure for updating ICR1 differs from updating OCR1A when used for defining the TOP
value. The ICR1 Register is not double buffered. This means that if ICR1 is changed to a low
value when the counter is running with none or a low prescaler value, there is a risk that the new
ICR1 value written is lower than the current value of TCNT1. The result will then be that the
counter will miss the compare match at the TOP value. The counter will then have to count to the
MAX value (0xFFFF) and wrap around starting at 0x0000 before the compare match can occur.
The OCR1A Register however, is double buffered. This feature allows the OCR1A I/O location
to be written anytime. When the OCR1A I/O location is written the value written will be put into
the OCR1A Buffer Register. The OCR1A Compare Register will then be updated with the value
in the Buffer Register at the next timer clock cycle the TCNT1 matches TOP. The update is done
at the same timer clock cycle as the TCNT1 is cleared and the TOV1 flag is set.
Using the ICR1 Register for defining TOP works well when using fixed TOP values. By using
ICR1, the OCR1A Register is free to be used for generating a PWM output on OC1A. However,
if the base PWM frequency is actively changed (by changing the TOP value), using the OCR1A
as TOP is clearly a better choice due to its double buffer feature.
In fast PWM mode, the compare units allow generation of PWM waveforms on the OC1x pins.
Setting the COM1x1:0 bits to two will produce a non-inverted PWM and an inverted PWM output
can be generated by setting the COM1x1:0 to three (see Table 43 on page 104). The actual
OC1x value will only be visible on the port pin if the data direction for the port pin is set as output
(DDR_OC1x). The PWM waveform is generated by setting (or clearing) the OC1x Register at
the compare match between OCR1x and TCNT1, and clearing (or setting) the OC1x Register at
the timer clock cycle the counter is cleared (changes from TOP to BOTTOM).
The PWM frequency for the output can be calculated by the following equation:
The N variable represents the prescaler divider (1, 8, 64, 256, or 1024).
The extreme values for the OCR1x Register represents special cases when generating a PWM
waveform output in the fast PWM mode. If the OCR1x is set equal to BOTTOM (0x0000) the output
will be a narrow spike for each TOP+1 timer clock cycle. Setting the OCR1x equal to TOP
will result in a constant high or low output (depending on the polarity of the output set by the
COM1x1:0 bits.)
A frequency (with 50% duty cycle) waveform output in fast PWM mode can be achieved by setting
OCF1A to toggle its logical level on each compare match (COM1A1:0 = 1). The waveform
generated will have a maximum frequency of fOC1A = fclk_I/O/2 when OCR1A is set to zero
(0x0000). This feature is similar to the OCF1A toggle in CTC mode, except the double buffer
feature of the Output Compare unit is enabled in the fast PWM mode.

Phase Correct PWM
Mode
The phase correct Pulse Width Modulation or phase correct PWM mode (WGM13:0 = 1, 2, 3,
10, or 11) provides a high resolution phase correct PWM waveform generation option. The
phase correct PWM mode is, like the phase and frequency correct PWM mode, based on a dualslope
operation. The counter counts repeatedly from BOTTOM (0x0000) to TOP and then from
TOP to BOTTOM. In non-inverting Compare Output mode, the Output Compare (OC1x) is
cleared on the compare match between TCNT1 and OCR1x while upcounting, and set on the
compare match while downcounting. In inverting Output Compare mode, the operation is
inverted. The dual-slope operation has lower maximum operation frequency than single slope
operation. However, due to the symmetric feature of the dual-slope PWM modes, these modes
are preferred for motor control applications.
The PWM resolution for the phase correct PWM mode can be fixed to 8-, 9-, or 10-bit, or defined
by either ICR1 or OCR1A. The minimum resolution allowed is 2-bit (ICR1 or OCR1A set to
0x0003), and the maximum resolution is 16-bit (ICR1 or OCR1A set to MAX). The PWM resolution
in bits can be calculated by using the following equation:
In phase correct PWM mode the counter is incremented until the counter value matches either
one of the fixed values 0x00FF, 0x01FF, or 0x03FF (WGM13:0 = 1, 2, or 3), the value in ICR1
(WGM13:0 = 10), or the value in OCR1A (WGM13:0 = 11). The counter has then reached the
TOP and changes the count direction. The TCNT1 value will be equal to TOP for one timer clock
cycle. The timing diagram for the phase correct PWM mode is shown on Figure 47. The figure
shows phase correct PWM mode when OCR1A or ICR1 is used to define TOP. The TCNT1
value is in the timing diagram shown as a histogram for illustrating the dual-slope operation. The
diagram includes non-inverted and inverted PWM outputs. The small horizontal line marks on
the TCNT1 slopes represent compare matches between OCR1x and TCNT1. The OC1x interrupt
flag will be set when a compare match occurs.
Figure 47. Phase Correct PWM Mode, Timing Diagram
The Timer/Counter Overflow Flag (TOV1) is set each time the counter reaches BOTTOM. When
either OCR1A or ICR1 is used for defining the TOP value, the OCF1A or ICF1 flag is set accordingly
at the same timer clock cycle as the OCR1x Registers are updated with the double buffer

value (at TOP). The interrupt flags can be used to generate an interrupt each time the counter
reaches the TOP or BOTTOM value.
When changing the TOP value the program must ensure that the new TOP value is higher or
equal to the value of all of the Compare Registers. If the TOP value is lower than any of the
Compare Registers, a compare match will never occur between the TCNT1 and the OCR1x.
Note that when using fixed TOP values, the unused bits are masked to zero when any of the
OCR1x Registers are written. As the third period shown in Figure 47 illustrates, changing the
TOP actively while the Timer/Counter is running in the phase correct mode can result in an
unsymmetrical output. The reason for this can be found in the time of update of the OCR1x Register.
Since the OCR1x update occurs at TOP, the PWM period starts and ends at TOP. This
implies that the length of the falling slope is determined by the previous TOP value, while the
length of the rising slope is determined by the new TOP value. When these two values differ the
two slopes of the period will differ in length. The difference in length gives the unsymmetrical
result on the output.
It is recommended to use the phase and frequency correct mode instead of the phase correct
mode when changing the TOP value while the Timer/Counter is running. When using a static
TOP value there are practically no differences between the two modes of operation.
In phase correct PWM mode, the compare units allow generation of PWM waveforms on the
OC1x pins. Setting the COM1x1:0 bits to two will produce a non-inverted PWM and an inverted
PWM output can be generated by setting the COM1x1:0 to three (See Table 44 on page 104).
The actual OC1x value will only be visible on the port pin if the data direction for the port pin is
set as output (DDR_OC1x). The PWM waveform is generated by setting (or clearing) the OC1x
Register at the compare match between OCR1x and TCNT1 when the counter increments, and
clearing (or setting) the OC1x Register at compare match between OCR1x and TCNT1 when
the counter decrements. The PWM frequency for the output when using phase correct PWM can
be calculated by the following equation:
The N variable represents the prescaler divider (1, 8, 64, 256, or 1024).
The extreme values for the OCR1x Register represent special cases when generating a PWM
waveform output in the phase correct PWM mode. If the OCR1x is set equal to BOTTOM the
output will be continuously low and if set equal to TOP the output will be continuously high for
non-inverted PWM mode. For inverted PWM the output will have the opposite logic values.

Phase and Frequency
Correct PWM Mode
The phase and frequency correct Pulse Width Modulation, or phase and frequency correct PWM
mode (WGM13:0 = 8 or 9) provides a high resolution phase and frequency correct PWM waveform
generation option. The phase and frequency correct PWM mode is, like the phase correct
PWM mode, based on a dual-slope operation. The counter counts repeatedly from BOTTOM
(0x0000) to TOP and then from TOP to BOTTOM. In non-inverting Compare Output mode, the
Output Compare (OC1x) is cleared on the compare match between TCNT1 and OCR1x while
upcounting, and set on the compare match while downcounting. In inverting Compare Output
mode, the operation is inverted. The dual-slope operation gives a lower maximum operation frequency
compared to the single-slope operation. However, due to the symmetric feature of the
dual-slope PWM modes, these modes are preferred for motor control applications.
The main difference between the phase correct, and the phase and frequency correct PWM
mode is the time the OCR1x Register is updated by the OCR1x Buffer Register, (see Figure 47
and Figure 48).
The PWM resolution for the phase and frequency correct PWM mode can be defined by either
ICR1 or OCR1A. The minimum resolution allowed is 2-bit (ICR1 or OCR1A set to 0x0003), and
the maximum resolution is 16-bit (ICR1 or OCR1A set to MAX). The PWM resolution in bits can
be calculated using the following equation:
In phase and frequency correct PWM mode the counter is incremented until the counter value
matches either the value in ICR1 (WGM13:0 = 8), or the value in OCR1A (WGM13:0 = 9). The
counter has then reached the TOP and changes the count direction. The TCNT1 value will be
equal to TOP for one timer clock cycle. The timing diagram for the phase correct and frequency
correct PWM mode is shown on Figure 48. The figure shows phase and frequency correct PWM
mode when OCR1A or ICR1 is used to define TOP. The TCNT1 value is in the timing diagram
shown as a histogram for illustrating the dual-slope operation. The diagram includes noninverted
and inverted PWM outputs. The small horizontal line marks on the TCNT1 slopes represent
compare matches between OCR1x and TCNT1. The OC1x interrupt flag will be set when a
compare match occurs.

The Timer/Counter Overflow Flag (TOV1) is set at the same timer clock cycle as the OCR1x
Registers are updated with the double buffer value (at BOTTOM). When either OCR1A or ICR1
is used for defining the TOP value, the OCF1A or ICF1 flag set when TCNT1 has reached TOP.
The interrupt flags can then be used to generate an interrupt each time the counter reaches the
TOP or BOTTOM value.
When changing the TOP value the program must ensure that the new TOP value is higher or
equal to the value of all of the Compare Registers. If the TOP value is lower than any of the
Compare Registers, a compare match will never occur between the TCNT1 and the OCR1x.
As Figure 48 shows the output generated is, in contrast to the phase correct mode, symmetrical
in all periods. Since the OCR1x Registers are updated at BOTTOM, the length of the rising and
the falling slopes will always be equal. This gives symmetrical output pulses and is therefore frequency
correct.
Using the ICR1 Register for defining TOP works well when using fixed TOP values. By using
ICR1, the OCR1A Register is free to be used for generating a PWM output on OC1A. However,
if the base PWM frequency is actively changed by changing the TOP value, using the OCR1A as
TOP is clearly a better choice due to its double buffer feature.
In phase and frequency correct PWM mode, the compare units allow generation of PWM waveforms
on the OC1x pins. Setting the COM1x1:0 bits to two will produce a non-inverted PWM and
an inverted PWM output can be generated by setting the COM1x1:0 to three (See Table 45 on
page 105). The actual OC1Fx value will only be visible on the port pin if the data direction for the
port pin is set as output (DDR_OCF1x). The PWM waveform is generated by setting (or clearing)
the OCF1x Register at the compare match between OCR1x and TCNT1 when the counter increments,
and clearing (or setting) the OCF1x Register at compare match between OCR1x and
TCNT1 when the counter decrements. The PWM frequency for the output when using phase
and frequency correct PWM can be calculated by the following equation:
The N variable represents the prescaler divider (1, 8, 64, 256, or 1024).
The extreme values for the OCR1x Register represents special cases when generating a PWM
waveform output in the phase correct PWM mode. If the OCR1x is set equal to BOTTOM the
output will be continuously low and if set equal to TOP the output will be set to high for noninverted
PWM mode. For inverted PWM the output will have the opposite logic values.

The Timer/Counter is a synchronous design and the timer clock (clkT1) is therefore shown as a
clock enable signal in the following figures. The figures include information on when interrupt
flags are set, and when the OCR1x Register is updated with the OCR1x buffer value (only for
modes utilizing double buffering). Figure 49 shows a timing diagram for the setting of OCF1x.

Figure 51 shows the count sequence close to TOP in various modes. When using phase and
frequency correct PWM mode the OCR1x Register is updated at BOTTOM. The timing diagrams
will be the same, but TOP should be replaced by BOTTOM, TOP-1 by BOTTOM+1 and so on.
The same renaming applies for modes that set the TOV1 flag at BOTTOM.

Control Register A –
TCCR1A
• Bit 7:6 – COM1A1:0: Compare Output Mode for Channel A
• Bit 5:4 – COM1B1:0: Compare Output Mode for Channel B
The COM1A1:0 and COM1B1:0 control the Output Compare pins (OC1A and OC1B respectively)
behavior. If one or both of the COM1A1:0 bits are written to one, the OC1A output
overrides the normal port functionality of the I/O pin it is connected to. If one or both of the
COM1B1:0 bit are written to one, the OC1B output overrides the normal port functionality of the
I/O pin it is connected to. However, note that the Data Direction Register (DDR) bit corresponding
to the OC1A or OC1B pin must be set in order to enable the output driver.
When the OC1A or OC1B is connected to the pin, the function of the COM1x1:0 bits is dependent
of the WGM13:0 bits setting. Table 43 shows the COM1x1:0 bit functionality when the
WGM13:0 bits are set to a Normal or a CTC mode (non-PWM).
Table 44 shows the COM1x1:0 bit functionality when the WGM13:0 bits are set to the fast PWM
mode.

generation to be used, see Table 46. Modes of operation supported by the Timer/Counter

Control Register B –
TCCR1B
• Bit 7 – ICNC1: Input Capture Noise Canceler
Setting this bit (to one) activates the Input Capture Noise Canceler. When the noise canceler is
activated, the input from the Input Capture pin (ICP1) is filtered. The filter function requires four
successive equal valued samples of the ICP1 pin for changing its output. The Input Capture is
therefore delayed by four Oscillator cycles when the noise canceler is enabled.
• Bit 6 – ICES1: Input Capture Edge Select
This bit selects which edge on the Input Capture pin (ICP1) that is used to trigger a capture
event. When the ICES1 bit is written to zero, a falling (negative) edge is used as trigger, and
when the ICES1 bit is written to one, a rising (positive) edge will trigger the capture.
When a capture is triggered according to the ICES1 setting, the counter value is copied into the
Input Capture Register (ICR1). The event will also set the Input Capture Flag (ICF1), and this
can be used to cause an Input Capture Interrupt, if this interrupt is enabled.
When the ICR1 is used as TOP value (see description of the WGM13:0 bits located in the
TCCR1A and the TCCR1B Register), the ICP1 is disconnected and consequently the Input Capture
function is disabled.
• Bit 5 – Reserved Bit
This bit is reserved for future use. For ensuring compatibility with future devices, this bit must be
written to zero when TCCR1B is written.
• Bit 4:3 – WGM13:2: Waveform Generation Mode
See TCCR1A Register description.
• Bit 2:0 – CS12:0: Clock Select
The three Clock Select bits select the clock source to be used by the Timer/Counter, see Figure
49 and Figure 50.
If external pin modes are used for the Timer/Counter1, transitions on the T1 pin will clock the
counter even if the pin is configured as an output. This feature allows software control of the
counting.

Control Register C –

• Bit 7 – FOC1A: Force Output Compare for Channel A
• Bit 6 – FOC1B: Force Output Compare for Channel B
The FOC1A/FOC1B bits are only active when the WGM13:0 bits specifies a non-PWM mode.
However, for ensuring compatibility with future devices, these bits must be set to zero when
TCCR1A is written when operating in a PWM mode. When writing a logical one to the
FOC1A/FOC1B bit, an immediate compare match is forced on the Waveform Generation unit.
The OC1A/OC1B output is changed according to its COM1x1:0 bits setting. Note that the
FOC1A/FOC1B bits are implemented as strobes. Therefore it is the value present in the
COM1x1:0 bits that determine the effect of the forced compare.
A FOC1A/FOC1B strobe will not generate any interrupt nor will it clear the timer in Clear Timer
on Compare match (CTC) mode using OCR1A as TOP.
The FOC1A/FOC1B bits are always read as zero.
Timer/Counter1 –
TCNT1H and TCNT1L
The two Timer/Counter I/O locations (TCNT1H and TCNT1L, combined TCNT1) give direct
access, both for read and for write operations, to the Timer/Counter unit 16-bit counter. To
ensure that both the high and low bytes are read and written simultaneously when the CPU
accesses these registers, the access is performed using an 8-bit temporary high byte register
(TEMP). This temporary register is shared by all the other 16-bit registers. See “Accessing 16-bit
Registers” on page 84.
Modifying the counter (TCNT1) while the counter is running introduces a risk of missing a compare
match between TCNT1 and one of the OCR1x Registers.
Writing to the TCNT1 Register blocks (removes) the compare match on the following timer clock
for all compare units.

Output Compare
Register 1 B -
OCR1BH and OCR1BL
The Output Compare Registers contain a 16-bit value that is continuously compared with the
counter value (TCNT1). A match can be used to generate an Output Compare interrupt, or to
generate a waveform output on the OC1x pin.
The Output Compare Registers are 16-bit in size. To ensure that both the high and low bytes are
written simultaneously when the CPU writes to these registers, the access is performed using an
8-bit temporary high byte register (TEMP). This temporary register is shared by all the other 16-
bit registers. See “Accessing 16-bit Registers” on page 84.
Input Capture Register
1 – ICR1H and ICR1L
The Input Capture is updated with the counter (TCNT1) value each time an event occurs on the
ICP1 pin (or optionally on the Analog Comparator output for Timer/Counter1). The Input Capture
can be used for defining the counter TOP value.
The Input Capture Register is 16-bit in size. To ensure that both the high and low bytes are read
simultaneously when the CPU accesses these registers, the access is performed using an 8-bit
temporary high byte register (TEMP). This temporary register is shared by all the other 16-bit
registers. See “Accessing 16-bit Registers” on page 84.

The dashed boxes in the block diagram separate the three main parts of the USART (listed from
the top): Clock Generator, Transmitter and Receiver. Control registers are shared by all units.
The Clock Generation logic consists of synchronization logic for external clock input used by
synchronous slave operation, and the baud rate generator. The XCK (Transfer Clock) pin is only
used by synchronous transfer mode. The Transmitter consists of a single write buffer, a serial
Shift Register, Parity Generator and Control logic for handling different serial frame formats. The
write buffer allows a continuous transfer of data without any delay between frames. The
Receiver is the most complex part of the USART module due to its clock and data recovery
units. The recovery units are used for asynchronous data reception. In addition to the recovery
units, the Receiver includes a Parity Checker, Control logic, a Shift Register and a two level
receive buffer (UDR). The Receiver supports the same frame formats as the Transmitter, and
can detect Frame Error, Data OverRun and Parity Errors.
AVR USART vs. AVR
UART – Compatibility
The USART is fully compatible with the AVR UART regarding:
• Bit locations inside all USART Registers.
• Baud Rate Generation.
• Transmitter Operation.
• Transmit Buffer Functionality.
• Receiver Operation.
However, the receive buffering has two improvements that will affect the compatibility in some
special cases:
• A second Buffer Register has been added. The two Buffer Registers operate as a circular
FIFO buffer. Therefore the UDR must only be read once for each incoming data! More
important is the fact that the error flags (FE and DOR) and the ninth data bit (RXB8) are
buffered with the data in the receive buffer. Therefore the status bits must always be read
before the UDR Register is read. Otherwise the error status will be lost since the buffer state
is lost.
• The Receiver Shift Register can now act as a third buffer level. This is done by allowing the
received data to remain in the serial Shift Register (see Figure 53) if the Buffer Registers are
full, until a new start bit is detected. The USART is therefore more resistant to Data OverRun
(DOR) error conditions.
The following control bits have changed name, but have same functionality and register location:
• CHR9 is changed to UCSZ2.
• OR is changed to DOR.
Clock Generation The Clock Generation logic generates the base clock for the Transmitter and Receiver. The
USART supports four modes of clock operation: Normal asynchronous, Double Speed asynchronous,
Master synchronous and Slave synchronous mode. The UMSEL bit in USART
Control and Status Register C (UCSRC) selects between asynchronous and synchronous operation.
Double Speed (asynchronous mode only) is controlled by the U2X found in the UCSRA
Register. When using synchronous mode (UMSEL = 1), the Data Direction Register for the XCK
pin (DDR_XCK) controls whether the clock source is internal (Master mode) or external (Slave
mode). The XCK pin is only active when using synchronous mode.
Figure 54 shows a block diagram of the clock generation logic.113

Internal Clock
Generation – The
Baud Rate Generator
Internal clock generation is used for the asynchronous and the synchronous master modes of
operation. The description in this section refers to Figure 54.
The USART Baud Rate Register (UBRR) and the down-counter connected to it function as a
programmable prescaler or baud rate generator. The down-counter, running at system clock
(fosc), is loaded with the UBRR value each time the counter has counted down to zero or when
the UBRRL Register is written. A clock is generated each time the counter reaches zero. This
clock is the baud rate generator clock output (= fosc/(UBRR+1)). The Transmitter divides the
baud rate generator clock output by 2, 8 or 16 depending on mode. The baud rate generator output
is used directly by the Receiver’s clock and data recovery units. However, the recovery units
use a state machine that uses 2, 8 or 16 states depending on mode set by the state of the
UMSEL, U2X and DDR_XCK bits.
Table 48 contains equations for calculating the baud rate (in bits per second) and for calculating
the UBRR value for each mode of operation using an internally generated clock source.
Note: 1. The baud rate is defined to be the transfer rate in bit per second (bps)

Double Speed
Operation (U2X)
The transfer rate can be doubled by setting the U2X bit in UCSRA. Setting this bit only has effect
for the asynchronous operation. Set this bit to zero when using synchronous operation.
Setting this bit will reduce the divisor of the baud rate divider from 16 to 8, effectively doubling
the transfer rate for asynchronous communication. Note however that the Receiver will in this
case only use half the number of samples (reduced from 16 to 8) for data sampling and clock
recovery, and therefore a more accurate baud rate setting and system clock are required when
this mode is used. For the Transmitter, there are no downsides.
External Clock External clocking is used by the synchronous slave modes of operation. The description in this
section refers to Figure 54 for details.
External clock input from the XCK pin is sampled by a synchronization register to minimize the
chance of meta-stability. The output from the synchronization register must then pass through
an edge detector before it can be used by the Transmitter and Receiver. This process introduces
a two CPU clock period delay and therefore the maximum external XCK clock frequency
is limited by the following equation:
Note that fosc depends on the stability of the system clock source. It is therefore recommended to
add some margin to avoid possible loss of data due to frequency variations.
Synchronous Clock
Operation
When synchronous mode is used (UMSEL = 1), the XCK pin will be used as either clock input
(Slave) or clock output (Master). The dependency between the clock edges and data sampling
or data change is the same. The basic principle is that data input (on RxD) is sampled at the
opposite XCK clock edge of the edge the data output (TxD) is changed.
Figure 55. Synchronous Mode XCK Timing.
The UCPOL bit UCRSC selects which XCK clock edge is used for data sampling and which is
used for data change. As Figure 55 shows, when UCPOL is zero the data will be changed at risf

ing XCK edge and sampled at falling XCK edge. If UCPOL is set, the data will be changed at
falling XCK edge and sampled at rising XCK edge.
Frame Formats A serial frame is defined to be one character of data bits with synchronization bits (start and stop
bits), and optionally a parity bit for error checking. The USART accepts all 30 combinations of
the following as valid frame formats:
• 1 start bit
• 5, 6, 7, 8, or 9 data bits
• no, even or odd parity bit
• 1 or 2 stop bits
A frame starts with the start bit followed by the least significant data bit. Then the next data bits,
up to a total of nine, are succeeding, ending with the most significant bit. If enabled, the parity bit
is inserted after the data bits, before the stop bits. When a complete frame is transmitted, it can
be directly followed by a new frame, or the communication line can be set to an idle (high) state.
Figure 56 illustrates the possible combinations of the frame formats. Bits inside brackets are
optional.
Figure 56. Frame Formats
St Start bit, always low.
(n) Data bits (0 to 8).
P Parity bit. Can be odd or even.
Sp Stop bit, always high.
IDLE No transfers on the communication line (RxD or TxD). An IDLE line must be
high.
The frame format used by the USART is set by the UCSZ2:0, UPM1:0 and USBS bits in UCSRB
and UCSRC. The Receiver and Transmitter use the same setting. Note that changing the setting
of any of these bits will corrupt all ongoing communication for both the Receiver and Transmitter.
The USART Character SiZe (UCSZ2:0) bits select the number of data bits in the frame. The
USART Parity mode (UPM1:0) bits enable and set the type of parity bit. The selection between
one or two stop bits is done by the USART Stop Bit Select (USBS) bit. The Receiver ignores the
second stop bit. An FE (Frame Error) will therefore only be detected in the cases where the first
stop bit is zero.
Parity Bit Calculation The parity bit is calculated by doing an exclusive-or of all the data bits. If odd parity is used, the
result of the exclusive or is inverted. The relation between the parity bit and data bits is as
follows:
Peven Parity bit using even parity
Podd Parity bit using odd parity

If used, the parity bit is located between the last data bit and first stop bit of a serial frame.
USART
Initialization
The USART has to be initialized before any communication can take place. The initialization process
normally consists of setting the baud rate, setting frame format and enabling the
Transmitter or the Receiver depending on the usage. For interrupt driven USART operation, the
Global Interrupt Flag should be cleared (and interrupts globally disabled) when doing the
initialization.
Before doing a re-initialization with changed baud rate or frame format, be sure that there are no
ongoing transmissions during the period the registers are changed. The TXC flag can be used to
check that the Transmitter has completed all transfers, and the RXC flag can be used to check
that there are no unread data in the receive buffer. Note that the TXC flag must be cleared
before each transmission (before UDR is written) if it is used for this purpose.
The following simple USART initialization code examples show one assembly and one C function
that are equal in functionality. The examples assume asynchronous operation using polling
(no interrupts enabled) and a fixed frame format. The baud rate is given as a function parameter.
For the assembly code, the baud rate parameter is assumed to be stored in the r17:r16
Registers.
Note: 1. The example code assumes that the part specific header file is included.
For I/O Registers located in extended I/O map, “IN”, “OUT”, “SBIS”, “SBIC”, “CBI”, and “SBI”
instructions must be replaced with instructions that allow access to extended I/O. Typically
“LDS” and “STS” combined with “SBRS”, “SBRC”, “SBR”, and “CBR”.
Assembly Code Example(1)
USART_Init:

ldi r16, (1<>8);
UBRRL = (unsigned char)baud;
/* Enable receiver and transmitter */
UCSRB = (1<> 1) & 0x01;
return ((resh << 8) | resl);

2543L–AVR–08/10
ATtiny2313
Note: 1. The example code assumes that the part specific header file is included.
For I/O Registers located in extended I/O map, “IN”, “OUT”, “SBIS”, “SBIC”, “CBI”, and “SBI”
instructions must be replaced with instructions that allow access to extended I/O. Typically
“LDS” and “STS” combined with “SBRS”, “SBRC”, “SBR”, and “CBR”.
The receive function example reads all the I/O Registers into the Register File before any computation
is done. This gives an optimal receive buffer utilization since the buffer location read will
be free to accept new data as early as possible.
Receive Compete Flag
and Interrupt
The USART Receiver has one flag that indicates the Receiver state.
The Receive Complete (RXC) flag indicates if there are unread data present in the receive buffer.
This flag is one when unread data exist in the receive buffer, and zero when the receive
buffer is empty (i.e., does not contain any unread data). If the Receiver is disabled (RXEN = 0),
the receive buffer will be flushed and consequently the RXC bit will become zero.
When the Receive Complete Interrupt Enable (RXCIE) in UCSRB is set, the USART Receive
Complete interrupt will be executed as long as the RXC flag is set (provided that global interrupts
are enabled). When interrupt-driven data reception is used, the receive complete routine
must read the received data from UDR in order to clear the RXC flag, otherwise a new interrupt
will occur once the interrupt routine terminates.
Receiver Error Flags The USART Receiver has three error flags: Frame Error (FE), Data OverRun (DOR) and Parity
Error (UPE). All can be accessed by reading UCSRA. Common for the error flags is that they are
located in the receive buffer together with the frame for which they indicate the error status. Due
to the buffering of the error flags, the UCSRA must be read before the receive buffer (UDR),
since reading the UDR I/O location changes the buffer read location. Another equality for the
error flags is that they can not be altered by software doing a write to the flag location. However,
all flags must be set to zero when the UCSRA is written for upward compatibility of future
USART implementations. None of the error flags can generate interrupts.
The Frame Error (FE) flag indicates the state of the first stop bit of the next readable frame
stored in the receive buffer. The FE flag is zero when the stop bit was correctly read (as one),
and the FE flag will be one when the stop bit was incorrect (zero). This flag can be used for
detecting out-of-sync conditions, detecting break conditions and protocol handling. The FE flag
is not affected by the setting of the USBS bit in UCSRC since the Receiver ignores all, except for
the first, stop bits. For compatibility with future devices, always set this bit to zero when writing to
UCSRA.
The Data OverRun (DOR) flag indicates data loss due to a receiver buffer full condition. A Data
OverRun occurs when the receive buffer is full (two characters), it is a new character waiting in
the Receive Shift Register, and a new start bit is detected. If the DOR flag is set there was one
or more serial frame lost between the frame last read from UDR, and the next frame read from
UDR. For compatibility with future devices, always write this bit to zero when writing to UCSRA.
The DOR flag is cleared when the frame received was successfully moved from the Shift Register
to the receive buffer.
The Parity Error (UPE) Flag indicates that the next frame in the receive buffer had a Parity Error
when received. If Parity Check is not enabled the UPE bit will always be read zero. For compatibility
with future devices, always set this bit to zero when writing to UCSRA. For more details see
“Parity Bit Calculation” on page 115 and “Parity Checker” on page 124.124
2543L–AVR–08/10
ATtiny2313
Parity Checker The Parity Checker is active when the high USART Parity mode (UPM1) bit is set. Type of Parity
Check to be performed (odd or even) is selected by the UPM0 bit. When enabled, the Parity
Checker calculates the parity of the data bits in incoming frames and compares the result with
the parity bit from the serial frame. The result of the check is stored in the receive buffer together
with the received data and stop bits. The Parity Error (UPE) flag can then be read by software to
check if the frame had a Parity Error.
The UPE bit is set if the next character that can be read from the receive buffer had a Parity
Error when received and the Parity Checking was enabled at that point (UPM1 = 1). This bit is
valid until the receive buffer (UDR) is read.
Disabling the Receiver In contrast to the Transmitter, disabling of the Receiver will be immediate. Data from ongoing
receptions will therefore be lost. When disabled (i.e., the RXEN is set to zero) the Receiver will
no longer override the normal function of the RxD port pin. The Receiver buffer FIFO will be
flushed when the Receiver is disabled. Remaining data in the buffer will be lost
Flushing the Receive
Buffer
The receiver buffer FIFO will be flushed when the Receiver is disabled, i.e., the buffer will be
emptied of its contents. Unread data will be lost. If the buffer has to be flushed during normal
operation, due to for instance an error condition, read the UDR I/O location until the RXC flag is
cleared. The following code example shows how to flush the receive buffer.
Note: 1. The example code assumes that the part specific header file is included.
For I/O Registers located in extended I/O map, “IN”, “OUT”, “SBIS”, “SBIC”, “CBI”, and “SBI”
instructions must be replaced with instructions that allow access to extended I/O. Typically
“LDS” and “STS” combined with “SBRS”, “SBRC”, “SBR”, and “CBR”.
Asynchronous
Data Reception
The USART includes a clock recovery and a data recovery unit for handling asynchronous data
reception. The clock recovery logic is used for synchronizing the internally generated baud rate
clock to the incoming asynchronous serial frames at the RxD pin. The data recovery logic samples
and low pass filters each incoming bit, thereby improving the noise immunity of the
Receiver. The asynchronous reception operational range depends on the accuracy of the internal
baud rate clock, the rate of the incoming frames, and the frame size in number of bits.

Serial Programming
Algorithm
When writing serial data to the ATtiny2313, data is clocked on the rising edge of SCK.
When reading data from the ATtiny2313, data is clocked on the falling edge of SCK. See Figure
79, Figure 80 and Table 79 for timing details.
To program and verify the ATtiny2313 in the serial programming mode, the following sequence
is recommended (See four byte instruction formats in Table 78 on page 174):
1. Power-up sequence:
Apply power between VCC and GND while RESET and SCK are set to “0”. In some systems,
the programmer can not guarantee that SCK is held low during power-up. In this
case, RESET must be given a positive pulse of at least two CPU clock cycles duration
after SCK has been set to “0”.
2. Wait for at least 20 ms and enable serial programming by sending the Programming
Enable serial instruction to pin MOSI.
3. The serial programming instructions will not work if the communication is out of synchronization.
When in sync. the second byte (0x53), will echo back when issuing the third
byte of the Programming Enable instruction. Whether the echo is correct or not, all four
bytes of the instruction must be transmitted. If the 0x53 did not echo back, give RESET a
positive pulse and issue a new Programming Enable command.
4. The Flash is programmed one page at a time. The memory page is loaded one byte at a
time by supplying the 4 LSB of the address and data together with the Load Program
Memory Page instruction. To ensure correct loading of the page, the data low byte must
be loaded before data high byte is applied for a given address. The Program Memory
Page is stored by loading the Write Program Memory Page instruction with the 6 MSB of
the address. If polling (RDY/BSY) is not used, the user must wait at least tWD_FLASH before
issuing the next page. (See Table 77 on page 174.) Accessing the serial programming
interface before the Flash write operation completes can result in incorrect programming.
5. A: The EEPROM array is programmed one byte at a time by supplying the address and
data together with the appropriate Write instruction. An EEPROM memory location is first
automatically erased before new data is written. If polling (RDY/BSY) is not used, the user
must wait at least tWD_EEPROM before issuing the next byte. (See Table 77 on page 174.)
In a chip erased device, no 0xFFs in the data file(s) need to be programmed.
B: The EEPROM array is programmed one page at a time. The Memory page is loaded
one byte at a time by supplying the 2 LSB of the address and data together with the Load
EEPROM Memory Page instruction. The EEPROM Memory Page is stored by loading
the Write EEPROM Memory Page Instruction with the 5 MSB of the address. When using
EEPROM page access only byte locations loaded with the Load EEPROM Memory Page
instruction is altered. The remaining locations remain unchanged. If polling (RDY/BSY) is
not used, the used must wait at least tWD_EEPROM before issuing the next page (See Table
77 on page 174). In a chip erased device, no 0xFF in the data file(s) need to be
programmed.
6. Any memory location can be verified by using the Read instruction which returns the content
at the selected address at serial output MISO.
7. At the end of the programming session, RESET can be set high to commence normal
operation.
8. Power-off sequence (if needed):
Set RESET to “1”.

Notes: 1. All DC Characteristics contained in this data sheet are based on simulation and characterization of other AVR microcontrollers
manufactured in the same process technology. These values are preliminary values representing design targets, and
will be updated after characterization of actual silicon.
2. Typical values at +25°C.
3. “Max” means the highest value where the pin is guaranteed to be read as low.
4. “Min” means the lowest value where the pin is guaranteed to be read as high.
5. Although each I/O port can sink more than the test conditions (10 mA at VCC = 5V, 5 mA at VCC = 3V) under steady state
conditions (non-transient), the following must be observed:
1] The sum of all IOL, for all ports, should not exceed 60 mA.
If IOL exceeds the test condition, VOL may exceed the related specification. Pins are not guaranteed to sink current greater
than the listed test condition.
6. Although each I/O port can source more than the test conditions (10 mA at VCC = 5V, 5 mA at VCC = 3V) under steady state
conditions (non-transient), the following must be observed:
1] The sum of all IOH, for all ports, should not exceed 60 mA.
If IOH exceeds the test condition, VOH may exceed the related specification. Pins are not guaranteed to source current
greater than the listed test condition.

Maximum Speed
vs. VCC
Maximum frequency is dependent on VCC. As shown in Figure 82 and Figure 83, the Maximum
Frequency vs. VCC curve is linear between 1.8V < VCC < 2.7V and between 2.7V < VCC < 4.5V.

Typical
Characteristics
The following charts show typical behavior. These figures are not tested during manufacturing.
All current consumption measurements are performed with all I/O pins configured as inputs and
with internal pull-ups enabled. A sine wave generator with rail-to-rail output is used as clock
source.
The power consumption in Power-down mode is independent of clock selection.
The current consumption is a function of several factors such as: operating voltage, operating
frequency, loading of I/O pins, switching rate of I/O pins, code executed and ambient temperature.
The dominating factors are operating voltage and frequency.
The current drawn from capacitive loaded pins may be estimated (for one pin) as CL*VCC*f where
CL = load capacitance, VCC = operating voltage and f = average switching frequency of I/O pin.
The parts are characterized at frequencies higher than test limits. Parts are not guaranteed to
function properly at frequencies higher than the ordering code indicates.
The difference between current consumption in Power-down mode with Watchdog Timer
enabled and Power-down mode with Watchdog Timer disabled represents the differential current
drawn by the Watchdog Timer.

Note: 1. For compatibility with future devices, reserved bits should be written to zero if accessed. Reserved I/O memory addresses
should never be written.
2. I/O Registers within the address range 0x00 - 0x1F are directly bit-accessible using the SBI and CBI instructions. In these
registers, the value of single bits can be checked by using the SBIS and SBIC instructions.
3. Some of the status flags are cleared by writing a logical one to them. Note that, unlike most other AVRs, the CBI and SBI
instructions will only operate on the specified bit, and can therefore be used on registers containing such status flags. The
CBI and SBI instructions work with registers 0x00 to 0x1F only.
4. When using the I/O specific commands IN and OUT, the I/O addresses 0x00 - 0x3F must be used. When addressing I/O
Registers as data space using LD and ST instructions, 0x20 must be added to these addresses. 213

Errata The revision in this section refers to the revision of the ATtiny2313 device.
ATtiny2313 Rev C No known errata
ATtiny2313 Rev B • Wrong values read after Erase Only operation
• Parallel Programming does not work
• Watchdog Timer Interrupt disabled
• EEPROM can not be written below 1.9 volts
1. Wrong values read after Erase Only operation
At supply voltages below 2.7 V, an EEPROM location that is erased by the Erase Only operation
may read as programmed (0x00).
Problem Fix/Workaround
If it is necessary to read an EEPROM location after Erase Only, use an Atomic Write operation
with 0xFF as data in order to erase a location. In any case, the Write Only operation can
be used as intended. Thus no special considerations are needed as long as the erased location
is not read before it is programmed.
2. Parallel Programming does not work
Parallel Programming is not functioning correctly. Because of this, reprogramming of the
device is impossible if one of the following modes are selected:
– In-System Programming disabled (SPIEN unprogrammed)
– Reset Disabled (RSTDISBL programmed)
Problem Fix/Workaround
Serial Programming is still working correctly. By avoiding the two modes above, the device
can be reprogrammed serially.
3. Watchdog Timer Interrupt disabled
If the watchdog timer interrupt flag is not cleared before a new timeout occurs, the watchdog
will be disabled, and the interrupt flag will automatically be cleared. This is only applicable in
interrupt only mode. If the Watchdog is configured to reset the device in the watchdog timeout
following an interrupt, the device works correctly.
Problem fix / Workaround
Make sure there is enough time to always service the first timeout event before a new
watchdog timeout occurs. This is done by selecting a long enough time-out period.
4. EEPROM can not be written below 1.9 volts
Writing the EEPROM at VCC below 1.9 volts might fail.
Problem fix / Workaround
Do not write the EEPROM when VCC is below 1.9 volts.

1 Introduction
This application note describes how to implement a sensorless commutation of
BLDC motors with the ATAVRMC320 development kit.
The ATmega32M1 is equipped with integrated peripherals that reduce the number
of external components required in a BLDC application. The ATmega32M1 is
suitable for sensorless commutation and for commutation with Hall sensors as well,
but this application note focuses on the sensorless commutation.
The AVR928 Application Note describes the theory of the sensorless control
method and must be carefully read first.

2.2 MC300 jumper settings
Table 2-1. ATAVRMC300 jumpers setting for sensorless control
Designator Setting Function
J2 none provide +5V to supply the ATAVRMC310 board
On ATAVRMC300, Vm and Vin connectors can be supplied from the same +12V/7A
power supply. Nevertheless a separate +12V/1A can also be used to supply the Vin
(processor supply voltage).
2.3 Power-supply
This firmware example has been configured according to a power-supply Vm=12V.
This power-supply must be able to provide up to 4A output current.
2.4 Motor
The BLDC motor provided inside MC320 and MC300 Motor Control Kit has the
following characteristics:
Manufacturer : TECMOTION
Number of phases : 3
Number of poles : 8 (4 pairs)
Rated voltage : 24V
Rated speed : 4000 rpm
Rated torque : 62.5 Nm
Torque constant : 35 Nm/A = k_tau4 AVR172
8306B-AVR-05/10
Line to Line Resistance : 1.8 ohm = R
Back EMF : 3.66 V/Krpm = k_e
Peak current : 5.4A
As Vm=12V, the rated speed will be 2000 rpm.
2.5 ATmega32M1 Configuration
ATmega32M1 must be programmed to run at 16MHz using PLL (set corresponding
Fuse bits).
The CKDIV8 fuse must be disabled.
Extended/High/Low Fuses configurations are : FF/DF/F3
2.6 Technical Advices
2.6.1 Disconnecting the BLDC Motor
The BLDC motor must not be disconnected while it is running or while its coils carry
current. It is allowed to disconnect a BLDC motor if the PWM duty cycle is 0% and the
rotor is at rest so that no current is driven through the coils. Be careful, when stopping
the power supply or PWM, a BLDC motor with a high moment of inertia is able to run
for a relatively long time.
2.6.2 Ground and Power Wirings
One design its own board has to take care of the ground wiring and power wiring. The
power supply of the processor and additional signal conditioning components (e.g.
additional fast comparators, operational amplifiers, …) has to be decoupled from the
motor power supply. The ground connection has to be of low resistance and low
inductance to prevent against voltage drop and noise due to high currents. A ground
plane within a multi layer PCB is recommended for proper operation.
3 Firmware
The example firmware is based on the Sensorless method described in AVR928
Application Note.
It is operating in sensorless mode using the ATmega32M1 internal comparators. Hall
sensor wires of the BLDC motor of the kit can remain unconnected.
The source file directory embeds an html documentation which can be opened
through the readme.html file.
The theory of the different tasks has been detailed in AVR928. The application to
ATmega32M1 is detailed in following sections.
3.1 Main Flow chart
The firmware main flowchart is described below : AVR172
5
8306B-AVR-05/10
Figure 2. Main flow chart
The tasks are scheduled thanks to the g_tick produced each 1.024ms with Timer0. 6 AVR172
8306B-AVR-05/10
3.2 MS_ALIGN phase
The ALIGN phase forces the motor at a specific position. The time of this phase is
controlled with ALIGN_TIME constant which is the ru_period_counter initial value
(200 for MC310 motor).
3.3 RAMP_UP phase
The ramp-up charateristics (duty-cycles and times) are stored in two tables:
• ramp_up_duty_table[] : which provides the duty_cycle of the step
• ramp_up_time_table[] : which provides the length of the step (ru_step_length)
These two tables are specific to the motor and the application.
The scanning of the step sequences and the monitoring of the step length are
achieved thanks to three independant counters :
- ru_step_length_cntr : which counts the commutation time (up to ru_step_length
variable)
- ru_period_counter : which counts the step length (up to RAMP_UP_PERIOD
constant)
- ramp_up_index : which counts the step numbers (up to
RAMP_UP_INDEX_MAX constant)
The figure below provides a waveform of steps timing :
Figure 3. Steps timing AVR172
7
8306B-AVR-05/10
3.3.1 Time of steps
The step time is RAMP_UP_PERIOD = 50ms.
3.3.2 Number of steps
The parameter : RAMP_UP_INDEX_MAX = 9, defines 10 steps ramp up.
3.3.3 Parameters tables
In firmware example, the tables have been defined according to the characteristics of
the motor provided in the kit (see parameters in 2.4 Motor section) :
ramp_up_time_table[] = {26,23,20,17,14,11,8,5,3,2,2};
ramp_up_duty_table[] = {122,124,126,129,131,133,135,137,140,143,145};
3.3.4 Sp1/pwm1
The usual parameters described in AVR928 Application Note are:
• Pwm1 = 50%
• Sp1 = Sp_max/60
The parameters defined with MC310 Tecmotion motor are:
• Pwm1 = 48% (= 122/256)
• Sp1 :
Sp1 is defined thanks to the initialization value of ru_step_length :
ru_step_length = RAMP_UP_STEP_MAX = 40
This variable determines one commutation each 40ms.
So an electrical rotation time is 120ms. As the motor has 4 pairs of poles, the
mechanical rotation time is 480ms. So the rotation speed is 60/0.48 = 125 rpm.
So Sp1 = Sp_max/32.
The second value of ru_step_length is 26 in the time table. It defines the following
commutation time.
3.3.5 Sp2/pwm2
The theorical parameters described in AVR928 Application Note are:
• Pwm2 = 60%
• Sp2 = Sp_max/6 = Sp1 / 10
The parameters defined with Tecmotion motor are:
• Pwm2 = 57% (= 145/256)
• Sp2 :
Sp2 is defined thanks to the last value of ru_step_length : 2
This variable determines one commutation each 4ms.
So an electrical rotation time is 12ms. As the motor has 4 pairs of poles, the
mechanical rotation time is 48ms. So the rotation speed is 60/0.048 = 1250 rpm.
So Sp2 = Sp_max/3.2. 8 AVR172
8306B-AVR-05/10
This confirms also the usual ratio = 10 between Sp1 and Sp2 which is defined in
AVR498 Application Note.
3.4 LAST_RAMP_UP phase
To avoid a shorten last step, this phase monitors the last ramp-up step to guarantee it
is ended properly before running in closed loop.
3.5 RUNNING Phase
3.5.1 Closed-loop block diagram
The Running phase is a sensorless closed loop which block diagram is following :
Figure 4. Closed-loop block diagram AVR172

8306B-AVR-05/10
3.5.2 Running flowchart
The flowchart is following :
Figure 5. Closed-loop flowchart
•
Motor_state is kept equal to MS_RUNNING
mci_set_ref_speed() function updates the speed setpoint according to the
potentiometer adjustment or the speed command received on serial transmission.
In mc_regulation_loop() function, duty_cycle_reference is the duty_cycle variable
which controls the PWM generator. This variable is the result of following functions :
• In OPEN_LOOP:
mci_set_ref_speed() function
• In SPEED_LOOP: 10 AVR172
8306B-AVR-05/10
mc_control_speed(2*mci_get_ref_speed())
duty-cycle_reference is calculated from ref_speed and from
monitored mci_get_measured_speed()
measured_speed = (KSPEED * 4) / mci_measured_period
with mci_measured_period calculated in the Interrupt vector of
Analog Comparator 1. This interrupt uses Timer 0 to compute the
period.
• In CURRENT_LOOP :
mc_control_current(mc_get_potentiometer_value()
3.5.3 Sensorless Detection and Commutation Management
The analog comparators 0, 1 and 2 are used to detect the zero crossing of the U, V
and W phases.
The timer 1 is used to monitor the time between two consecutive zero crossings. This
time corresponds to one sector of the electrical rotation of the motor. It equals 60° of
the entire electrical period of the motor.
When a zero crossing event occurs, the timer 1 value is stored. Then this value is
divided by 2 (providing the 30° time) and loaded into the Compare A register of timer
1. Then this value is added to the half of itself to provide the 45° time and loaded into
the Compare B register of timer 1.
The timer 1 compare A event occurs 30° after the zero crossing. It activates the next
commutation state and masks the zero crossing to avoid the discharge of the
inductance (demagnetization) pulse generated at the end of a step when the active
switches are released.
Due to the inductance of the motor coils, a voltage equals to -Ldi/dt is generated, the
demagnetization is done through the diodes of the power bridge.
The timer 1 compare B event releases the zero crossing mask : enables the
comparator n interrupt according to the motor_step variable. This Timer1 interrupt
provides the demagnetization mask delay. AVR172

• RDSR
The RDSR command reads status register data. After op-code of RDSR is input to SI, 8-cycle clock is input
to SCK. The SI value is invalid for this time. SO is output synchronously to a falling edge of SCK. In the
RDSR command, repeated reading of status register is enabled by sending SCK continuously before rising
of CS. RDSR command is applicable to “Up to 33 MHz operation”.
• WRSR
The WRSR command writes data to the nonvolatile memory bit of status register. After performing WRSR
op-code to a SI pin, 8 bits writing data is input. WEL (Write Enable Latch) is not able to be written with WRSR
command. A SI value correspondent to bit 1 is ignored. Bit 0 of the status register is fixed to “0” and cannot
be written. The SI value corresponding to bit 0 is ignored. The WP signal level shall be fixed before performing
the WRSR command, and do not change the WP signal level until the end of command sequence. WRSR
command is applicable to “Up to 33 MHz operation”.

• READ
The READ command reads FRAM memory cell array data. Arbitrary 16 bits address and op-code of READ
are input to SI. The 2-bit upper address bit is invalid. Then, 8-cycle clock is input to SCK. SO is output
synchronously to the falling edge of SCK. While reading, the SI value is invalid. When CS is risen, the READ
command is completed, but keeps on reading with automatic address increment which is enabled by continuously
sending clocks to SCK in unit of 8 cycles before CS rising. When it reaches the most significant
address, it rolls over to the starting address, and reading cycle keeps on infinitely. READ command is
applicable to “Up to 25 MHz operation”.
• WRITE
The WRITE command writes data to FRAM memory cell array. WRITE op-code, arbitrary 16 bits of address
and 8 bits of writing data are input to SI. The 2-bit upper address bit is invalid. When 8 bits of writing data is
input, data is written to FRAM memory cell array. Risen CS will terminate the WRITE command, but if you
continue sending the writing data for 8 bits each before CS rising, it is possible to continue writing with
automatic address increment. When it reaches the most significant address, it rolls over to the starting
address, and writing cycle can be continued infinitely. WRITE command is applicable to “Up to 33 MHz
operation”.

• FSTRD
The FSTRD command reads FRAM memory cell array data. Arbitrary 16 bits address and op-code of FSTRD
are input to SI followed by 8 bits dummy. The 2-bit upper address bit is invalid. Then, 8-cycle clock is input
to SCK. SO is output synchronously to the falling edge of SCK. While reading, the SI value is invalid. When
CS is risen, the FSTRD command is completed, but keeps on reading with automatic address increment
which is enabled by continuously sending clocks to SCK in unit of 8 cycles before CS rising. When it reaches
the most significant address, it rolls over to the starting address, and reading cycle keeps on infinitely.
FSTRD command is applicable to “Up to 33 MHz operation”.
• RDID
The RDID command reads fixed Device ID. After performing RDID op-code to SI, 32-cycle clock is input to
SCK. The SI value is invalid for this time. SO is output synchronously to a falling edge of SCK. The output
is in order of Manufacturer ID (8bit)/Continuation code (8bit)/Product ID (1st Byte)/Product ID (2nd Byte).
In the RDID command, SO holds the output state of the last bit after 32-bit Device ID output by continuously
sending SCK clock before CS is risen. RDID command is applicable to “Up to 33 MHz operation”.

■ BLOCK PROTECT
Writing protect block for WRITE command is configured by the value of BP0 and BP1 in the status register.
■ WRITING PROTECT
Writing operation of the WRITE command and the WRSR command are protected with the value of WEL,
WPEN, WP as shown in the table.
■ HOLD OPERATION
Hold status is retained without aborting a command if HOLD is the “L” level while CS is the “L” level. The
timing for starting and ending hold status depends on the SCK to be the “H” level or the “L” level when a
HOLD pin input is transited to the hold condition as shown in the diagram below. In case the HOLD pin
transited to “L” level when SCK is “L” level, return the HOLD pin to “H” level at SCK being “L” level. In the
same manner, in case the HOLD pin transited to “L” level when SCK is “H” level, return the HOLD pin to “H”
level at SCK being “H” level. Arbitrary command operation is interrupted in hold status, SCK and SI inputs
become don’t care. And, SO becomes High-Z while reading command (RDSR, READ) . If CS is rising during
hold status, a command is aborted. In case the command is aborted before its recognition, WEL holds the
value before transition to HOLD status.

NXP Semiconductors PESD5V0F1BL
Femtofarad bidirectional ESD protection diode
7. Application information
PESD5V0F1BL is designed for the protection of one bidirectional data or signal line from
the damage caused by ESD and surge pulses. The device may be used on lines where
the signal polarities are both, positive and negative with respect to ground.
Circuit board layout and protection device placement
Circuit board layout is critical for the suppression of ESD, Electrical Fast Transient (EFT)
and surge transients. The following guidelines are recommended:
1. Place the device as close to the input terminal or connector as possible.
2. The path length between the device and the protected line should be minimized.
3. Keep parallel signal paths to a minimum.
4. Avoid running protected conductors in parallel with unprotected conductors.
5. Minimize all Printed-Circuit Board (PCB) conductive loops including power and
ground loops.
6. Minimize the length of the transient return path to ground.
7. Avoid using shared transient return paths to a common ground point.
8. Ground planes should be used whenever possible. For multilayer PCBs, use ground
vias.
8. Test information
8.1 Quality information

DESCRIPTION
The SG3525A series of pulse width modulator integrated
circuits are designed to offer improved performance
and lowered external parts count when
used in designing all types of switching power supplies.
The on-chip + 5.1 V reference is trimmed to ±
1 % and the input common-mode range of the error
amplifier includes the reference voltage eliminating
external resistors. A sync input to the oscillator allows
multiple units to be slaved or a single unit to be
synchronized to an external system clock. A single
resistor between the CT and the discharge terminals
provide a wide range of dead time ad- justment.
These devices also feature built-in soft-start circuitry
with only an external timing capacitor required. A
shutdown terminal controls both the soft-start circuity
and the output stages, providing instantaneous
turn off through the PWM latch with pulsed shutdown,
as well as soft-start recycle with longer shutdown
commands. These functions are also controlled
by an undervoltage lockout which keeps the outputs
off and the soft-start capacitor discharged for
sub-normal input voltages. This lockout circuitry includes
approximately 500 mV of hysteresis for jitterfree
operation. Another feature of these PWM circuits
is a latch following the comparator. Once a
PWM pulses has been terminated for any reason,
the outputs will remain off for the duration of the period.
The latch is reset with each clock pulse. The
output stages are totem-pole designs capable of
sourcing or sinking in excess of 200 mA. The
SG3525A output stage features NOR logic, giving a
LOW output for an OFF state.

SHUTDOWN OPTIONS (see Block Diagram)
Since both the compensation and soft-start terminals
(Pins 9 and 8) have current source pull-ups,
either can readily accept a pull-down signal which
only has to sink a maximum of 100 mA to turn off the
outputs. This is subject to the added requirement of
discharging whatever external capacitance may be
attached to these pins.
An alternate approach is the use of the shutdown circuitry
of Pin 10 which has been improved to enhance
the available shutdown options. Activating
this circuit by applying a positive signal on Pin 10
performs two functions : the PWM latch is immediately
set providing the fastest turn-off signal to the
outputs ; and a 150 mA current sink begins to discharge
the external soft-start capacitor. If the shutdown
command is short, the PWM signal is terminated
without significant discharge of the soft-start
capacitor, thus, allowing, for example, a convenient
implementation of pulse-by-pulse current limiting.
Holding Pin 10 high for a longer duration, however,
will ultimately discharge this external capacitor, recycling
slow turn-on upon release.
Pin 10 should not be left floating as noise pickup
could conceivably interrupt normal operation.

Figure 10. Figure 11.
For single-ended supplies, the driver outputs are
grounded. The VC terminal is switched to ground by
the totem-pole source transistors on alternate oscillator
cycles.
In conventional push-pull bipolar designs, forward
base drive is controlled by R1 - R3. Rapid turn-off
times for the power devices are achieved with
speed-up capacitors C1 and C2.
The low source impedance of the output drivers provides
rapid charging of Power Mos input capacitance
while minimizing external components.
Low power transformers can be driven directly.
Automatic reset occurs during dead time, when both
ends of the primary winding are switched to ground.

Application note
1 kW dual stage DC-AC converter based on the STP160N75F3
Introduction
This application note provides design guidelines and performance characterization of the
STEVAL-ISV001V1 demonstration board.
This board implements a 1 kW dual stage DC-AC converter, suitable for use in batterypowered
uninterruptible power supplies (UPS) or photovoltaic (PV) standalone systems.
The converter is fed by a low DC input voltage varying from 20 V to 28 V, and is capable of
supplying up to 1 kW of output power on a single-phase AC load. These features are
possible thanks to a dual stage conversion topology that includes an efficient step-up pushpull
DC-DC converter, which produces a regulated high-voltage DC bus and a sinusoidal HBridge
PWM inverter to generate a 50 Hz, 230 Vrms output sine wave. Other key features of
the system proposed are high power density, high switching frequency and efficiency
greater than 90% over a wide output load range

1 System description
In a UPS system, as shown in Figure 2, a DC-AC converter is always used to convert the
DC power from the batteries to AC power used to supply the load. The basic scheme also
includes a battery pack, a battery charger which converts AC power from the grid into DC
power, and a transfer switch to supply the load from the mains or from the energy storage
elements if a line voltage drop or failure occurs.
Figure 2. Block diagram of an offline UPS system
Another application where a DC-AC converter is always required is shown in the block
diagram of Figure 3. In this case, the converter is part of a conversion scheme commonly
used in standalone photovoltaic systems. An additional DC-DC converter operates as a
battery charger while performing a maximum power point tracking algorithm (MPPT), which
is necessary to maximize the energy yield from the PV array. The battery pack is always
present to store energy when solar radiation is available and release it at night or during
hours of low insolation.
Figure 3. Possible use of a DC-AC converter in standalone PV conversion
A possible implementation of an isolated DC-AC converter, which can be successfully used
in both the above mentioned applications, is given in the block diagram of Figure 4. It
consists of three main sections:

The DC-DC section is a critical part of the converter design. In fact, the need for high overall
efficiency (close to 90% or higher) together with the specifications for continuous power
rating, low input voltage range leading to high input current, and the need for high switching
frequency to minimize weight and size of passive components, makes it a quite challenging
design.
Due to the constraints given by the specifications given in Table 1, few topology solutions
are suitable to meet the efficiency target. Actually, since the input voltage of the DC-AC
converter must be at least equal to 350 V, it is not feasible to use non-isolated DC-DC
converters. Moreover, the output power rating prevents the use of single switch topologies
such as the flyback and the forward. Among the remaining isolated topologies, the half
bridge and full bridge are more suitable for high DC input voltage applications and also
characterized by the added complexity of gate drive circuitry of the high side switches.
Due to such considerations, the push-pull represents the most suitable choice. This
topology features two transistors on the primary side and a center tapped high frequency
transformer, as shown in the step-up section in Figure 4. It is quite efficient at low input
voltage making it widely used in battery powered UPS applications. Both power devices are
ground referenced with consequent simple gate drive circuits. They are alternatively turned

on and off in order to transfer power to each primary of the center tapped transformer.
Contemporary conduction of both devices must be avoided by limiting the duty cycle value
of the constant frequency PWM modulator to less than 0.5. The PWM modulator should also
prevent unequal ON times for the driving signals since this would result in transformer
saturation caused by the "Flux Walking" phenomenon.
The basic operation is similar to a forward converter. In fact, when a primary switch is active,
the current flows through the rectifier diodes, charging the output inductor, while when both
the switches are off, the output inductor discharges. It is important to point out that the
operating frequency of the output inductor is twice the switching frequency.
A transformer reset circuit is not needed thanks to the bipolar flux operation, which also
means better transformer core utilization with respect to single-ended topologies.
The main disadvantage of the push-pull converter is the breakdown voltage of primary
power devices which has to be higher than twice the input voltage. In fact, when voltage is
applied to one of the two transformer primary windings by the conduction of a transistor, the
reflected voltage across the other primary winding puts the drain of the off state transistor at
twice the input voltage with respect to ground. This is the reason why push-pull converters
are not suitable for high input voltage applications.
For the above mentioned reasons, the voltage fed push-pull converter, shown in Figure 4, is
chosen to boost the input voltage from 24 V to a regulated 350 V, suitable for optimal
inverter operation. The high voltage conversion ratio can be achieved by proper transformer
turns ratio design, taking into account that the input to output voltage transfer function is
given by:
Equation 1
The duty cycle is set by a voltage mode PWM regulator (SG3525) to keep a constant output
DC bus voltage. This voltage is then converted into AC using a standard H-bridge converter
implemented with four ultrafast switching IGBTs in PowerMESH™ technology, switching at
16 kHz. The switching strategy, based on PWM sinusoidal modulation, is implemented on
an 8-bit ST7lite39 microcontroller unit. This allows the use of a simple LC circuit to obtain a
high quality sine wave in terms of harmonic content.
The power supply section consists of a buck-boost converter to produce a regulated 15 V
from a minimum input voltage of 4 V. The circuit can be simply implemented by means of a
L5973 device, characterized by an internal P-channel DMOS transistor and few external
components. In this way, it is possible to supply all the driving circuits and the PWM
modulator. A standard linear regulator, L7805, provides 5 V supply to the microcontroller
unit.

2 Design considerations
The basic operation of a voltage fed push-pull converter is shown in Figure 5, where
theoretical converter waveforms are highlighted. In practice, significant overvoltages across
devices M1, M2 and across the four rectifier diodes are observed in most cases due to the
leakage inductance of the high frequency transformer. As a consequence, the breakdown
voltage of primary devices must be greater than twice the input voltage, and the use of
snubbing and/or clamping circuits is often helpful.
Special attention has to be paid to transformer design, due to the difficulties in minimizing
the leakage inductance and implementing low-voltage high-current terminations. Moreover,
imbalance in the two primary inductance values must be avoided both by symmetrical
windings and proper printed circuit board (PCB) layout. While transformer construction
techniques guarantee good symmetry and low leakage inductance values, asymmetrical
layout due to inappropriate component placement can be the source of different PCB trace
inductances. Whatever the cause of a difference in peak current through the switching
elements, transformer saturation in voltage mode push-pull converters can occur in a few
switching cycles with catastrophic consequences.

Doc ID 14827 Rev 2 9/39
Starting from the specifications in Table 2, a step-by-step design procedure and some
design hints to obtain a symmetrical layout are given below.
A switching frequency of f = 100 kHz was chosen to minimize passive components size and
weight, then the following step-by-step calculation was done:
● Switching period:
Equation 2
● Maximum duty cycle
The theoretical maximum on time for each phase of the push-pull converter is:
Equation 3
Since deadtime has to be provided in order to avoid simultaneous device conduction, it is
better to choose the maximum duty cycle of each phase as:
Equation 4
This means a total deadtime of 1μs at maximum duty cycle, occurring for minimum input
voltage operation.

The Kg constant is related to the core geometrical parameters by the following equation:
Equation 32
where Wa is the core window area, Ac is the core cross sectional area and MLT is the mean
length per turn.
For example, choosing an E55/28/21 core with N27 ferrite, having
● Wa= 2.8 cm2
● Ac= 3.5 cm2
● MLT= 11.3 cm
the resulting Kg factor is:
● Kg= 0.91 cm2
which is then suitable for this application.
Once the core has been chosen, it is possible to calculate the number of primary turns as
follows:

The primary inductance value is:

Converter losses are distributed according to the graphic in Figure 6, where PCB trace
losses and control losses are not considered. What is important to note is that primary
switch conduction accounts for 36% of total DC-DC converter losses. This contribution can
be reduced by paralleling either two or three power devices. For example, by paralleling
three STP160N75F3s, a reduction in MOSFET conduction losses of 33% is achieved. Thus
MOSFET conduction losses account for 16% of total DC-DC converter losses, resulting in a

Because of the high power level involved with this design, the parasitic elements must be
reduced as much as possible. Proper operation of the push-pull converter can be assured
through geometrical symmetry of the PCB board. In fact, geometrical symmetry leads to
electrical symmetry, preventing a difference in the current values across the two primary
windings of the transformer which can be the cause of core saturation. The output stage of
the converter has also to be routed with a certain degree of symmetry even if in this case the
impact of unwanted parasitic elements is lower because of lower current values with respect
to the input stage. In Figure 8, Figure 9 and Figure 10, a symmetrical layout designed for the
application is shown.

To obtain geometrical symmetry the HF transformer has been placed at the center of the
board, which has been developed using double-sided, 140 μm FR-4 substrate with
135 x 185 mm size. In addition, this placement of the transformer is the most suitable since
it is the bulkiest part of the board. Both the primary and secondary AC current loops are
placed very close to the transformer in order to reduce their area and consequently their
parasitic inductances. For this reason the MOSFET and rectifier diodes lie at the edges of
the PCB. Input loop PCB traces show identical shapes to guarantee the same values of
resistance and parasitic inductance. Also the IGBTs of the inverter stage lie at one edge of
the board. This gives the advantage of using a single heat sink for each group of power
components. The output filter is placed on the right side of the transformer, between the
bridge rectifier and the inverter stage.
The power supply section lies on the left side of the transformer, simplifying the routing of
the 15 V bus dedicated to supply all the control circuitry.

3 Schematic description
The schematic of the converter is shown in Figure 11. Three MOSFETs are paralleled in
order to transfer power to each primary winding of the transformer. Both RC and RCD
networks can be connected between the drain and source of the MOSFETs to reduce the
overvoltages and voltage ringing caused by unclamped leakage inductance. The output of
the transformer is rectified by a full bridge of ultrafast soft-recovery diodes. An RCD network
is connected across the rectifier output to clamp the diode voltage to its steady state value
and recover the reverse recovery energy stored in the leakage inductance. This energy is
first transferred to the clamp capacitor and then partially diverted to the output through a
resistor.
The IGBT full bridge is connected to the output of the push-pull stage. Their control signals
are generated by an SG3525 voltage mode PWM modulator. Its internal clock, necessary to
generate the 100 kHz modulation, is set by an external RC network. The PWM output stage
is capable of sourcing or sinking up to 100 mA which can be enough to directly drive the
gate of the MOSFETs devices. The PWM controller power dissipation, given by the sum of
its own power consumption and the power needed to drive six STP160N75F3s at 100 kHz,
can be evaluated with the following equation:
Equation 67
where Vs and Is are the supply voltage and current.
Since this power dissipation would result in a high operating temperature of the IC, a totem
pole driving circuit has been used to handle the power losses and peak currents, achieving
a more favorable operating condition. This circuit was implemented by means of an NPNPNP
complementary pair of BJT transistors. The control and driver stage schematic is
shown in Figure 11.

4 Experimental results
Typical voltage and current waveforms of the DC-AC converter and the efficiency curves of
the push-pull DC-DC stage, measured at different input voltages, are shown below. In
particular, Figure 12 and Figure 13 show both input and output characteristic waveforms of
the DC-DC converter both in light load and full load condition.
The HF transformer leakage inductance, which is about 1% of the magnetizing inductance,
is the cause of severe ringing across the input and the output power devices. MOSFETs
voltage and current waveforms with and without the connection of a snubber network are
shown in Figure 14 and 15, while Figure 16 and 17 show the effect of the RCD clamp circuit
connected across the rectifier bridge output. In Figure 18 the current and the voltage across
one of the three parallel-connected MOSFETs, powering each of the two windings of the
transformer are shown, while in Figure 19 it is possible to observe the variation of the
inverter output voltage and current together with the DC-DC converter bus voltage. In
Figure 20, 21, 22, 23 and 24, the efficiency curves of the push-pull converter measured with
an RL load are given. A maximum efficiency above 93% has been measured at nominal
input voltage and 640 W output power. The minimum value of efficiency has been tested
under low load and maximum input voltage. In Figure 25, the efficiency of the whole board is
shown. The efficiency tests have been carried out connecting an RL load at the inverter

5 Conclusion
The theoretical analysis, design and implementation of a DC-AC converter, consisting of a
push-pull DC-DC stage and a full-bridge inverter circuit, have been evaluated. Due to the
use of the parallel connection of three STP160N75F3 MOSFETs the converter shows good
performance in terms of efficiency. Moreover the use of an ST7lite39 8-bit microcontroller
allows achieving simple control of the IGBTs used to implement the DC-AC stage. Any
additional feature, such as regulation of the AC output voltage or protection requirements,
can simply be achieved with firmware development.

Description
The L6384E is a high voltage gate driver,
manufactured with the BCD™ “offline”
technology, and able to drive a half-bridge of
power MOS or IGBT devices. The high-side
(floating) section is enabled to work with voltage
rail up to 600 V. Both device outputs can sink and
source 650 mA and 400 mA respectively and
cannot be simultaneously driven high thanks to an
integrated interlocking function. Further
prevention from outputs cross conduction is
guaranteed by the deadtime function, tunable by
the user through an external resistor connected to
the DT/SD pin.
The L6384E device has one input pin, one enable
pin (DT/SD) and two output pins, and guarantees
matched delays between low-side and high-side
sections, thus simplifying device's high frequency
operation. The logic inputs are CMOS/TTL
compatible to ease the interfacing with controlling
devices. The bootstrap diode is integrated inside
the device, allowing a more compact and reliable
solution.
The L6384E features the UVLO protection and
a voltage clamp on the VCC supply voltage. The
voltage clamp is typically around 15.6 V and is
useful in order to ensure a correct device
functioning in cases where VCC supply voltage is
ramped up too slowly or is subject to voltage
drops.
The device is available in a DIP-8 tube and SO-8
tube and tape and reel packaging options.

1 IN I Logic input: it is in phase with HVG and in opposition of phase with LVG. It is compatible
to VCC voltage. (Vil Max = 1.5 V, Vih Min = 3.6 V).
2 VCC P Supply input voltage: there is an internal clamp [typ. 15.6 V].
3 DT/SD I
High impedance pin with two functionalities. When pulled lower than Vdt (typ. 0.5 V), the
device is shut down. A voltage higher than Vdt sets the deadtime between the high-side
gate driver and low-side gate driver. The deadtime value can be set forcing a certain
voltage level on the pin or connecting a resistor between the pin 3 and ground. Care
must be taken to avoid below threshold spikes on the pin 3 that can cause undesired
shutdown of the IC. For this reason the connection of the components between the pin 3
and ground has to be as short as possible. This pin can not be left floating for the same
reason. The pin has not be pulled through a low impedance to VCC, because of the drop
on the current source that feeds Rdt. The operative range is: Vdt … 270 K Idt, that
allows a dt range of 0.4 - 3.1 s.
4 GND P Ground
5 LVG O
Low-side driver output: the output stage can deliver 400 mA source and 650 mA sink
(typ. values). The circuit guarantees 0.3 V max. on the pin (at Isink = 10 mA) with
VCC > 3 V and lower than the turn-on threshold. This allows to omit the bleeder resistor
connected between the gate and the source of the external MOSFET normally used to
hold the pin low; the gate driver ensures low impedance also in SD conditions.
6 Vout P High-side driver floating reference: layout care has to be taken to avoid below ground
spikes on this pin.
7 HVG O
High-side driver output: the output stage can deliver 400 mA source and 650 mA sink
(typ. values). The circuit guarantees 0.3 V max. between this pin and Vout
(at Isink = 10 mA) with VCC > 3 V and lower than the turn-on threshold. This allows to omit
the bleeder resistor connected between the gate and the source of the external MOSFET
normally used to hold the pin low; the gate driver ensures low impedance also in SD
conditions.
8 Vboot P
Bootstrap supply voltage: it is the high-side driver floating supply. The bootstrap capacitor
connected between this pin and the pin 6 can be fed by an internal structure named
“bootstrap driver” (a patented structure). This structure can replace the external
bootstrap diode.

Bootstrap driver L6384E

5 Bootstrap driver
A bootstrap circuitry is needed to supply the high voltage section. This function is normally
accomplished by a high voltage fast recovery diode (Figure 4 a). In the L6384E device
a patented integrated structure replaces the external diode. It is realized by a high voltage
DMOS, driven synchronously with the low-side driver (LVG), with a diode in series, as
shown in Figure 4 b. An internal charge pump (Figure 4 b) provides the DMOS driving
voltage. The diode connected in series to the DMOS has been added to avoid undesirable
turn-on.
CBOOT selection and charging
To choose the proper CBOOT value the external MOS can be seen as an equivalent
capacitor. This capacitor CEXT is related to the MOS total gate charge:
Equation 1
The ratio between the capacitors CEXT and CBOOT is proportional to the cyclical voltage loss.
It has to be:
CBOOT>>>CEXT
E.g.: if Qgate is 30 nC and Vgate is 10 V, CEXT is 3 nF. With CBOOT = 100 nF the drop would be
300 mV.
If HVG has to be supplied for a long time, the CBOOT selection has to take into account also
the leakage losses.
E.g.: HVG steady state consumption is lower than 100 A, so if HVG TON is 5 ms, CBOOT
has to supply 0.5 C to CEXT. This charge on a 1 F capacitor means a voltage drop of
0.5 V.
The internal bootstrap driver gives great advantages: the external fast recovery diode can
be avoided (it usually has a great leakage current).
This structure can work only if VOUT is close to GND (or lower) and in the meanwhile the
LVG is on. The charging time (Tcharge ) of the CBOOT is the time in which both conditions are
fulfilled and it has to be long enough to charge the capacitor.
The bootstrap driver introduces a voltage drop due to the DMOS RDSON (typical value:
125 ). At low frequency this drop can be neglected. Anyway increasing the frequency it
must be taken in to account.
The following equation is useful to compute the drop on the bootstrap DMOS:
Equation 2
where Qgate is the gate charge of the external power MOS, Rdson is the on-resistance of the
bootstrap DMOS, and Tcharge is the charging time of the bootstrap capacitor.

For example: using a power MOS with a total gate charge of 30 nC, the drop on the
bootstrap DMOS is about 1 V, if the Tcharge is 5 s. In fact:
Equation 3
Vdrop has to be taken into account when the voltage drop on CBOOT is calculated: if this drop
is too high, or the circuit topology doesn’t allow a sufficient charging time, an external diode
can be used.

6 Application hints
In operation, the LM350 develops a nominal 1.25 V reference voltage, V(REF), between the
output and adjustment terminal. The reference voltage is impressed across program resistor
R1 and, since the voltage is constant, a constant current I1 then flows through the output set
resistor R2, giving an output voltage of:
VO = V(REF) (1+ R2 / R1) + IADJ x R2.
Since the 50 μA current from the adjustment terminal represents an error term, the LM350
was designed to minimize IADJ and make it very constant with line and load changes. To do
this, all quiescent operating current is returned to the output establishing a minimum load
current requirement. If there is insufficient load on the output, the output will rise.
6.1 External capacitors
An input bypass capacitor is recommended. A 0.1 μF disc or 1 μF solid tantalum on the input
is suitable input by passing for almost all applications. The device is more sensitive to the
absence of input bypassing when adjustment or output capacitors are used by the above
values will eliminate the possibility of problems.
The adjustment terminal can be bypassed to ground on the LM350 to improve ripple
rejection. This bypass capacitor prevents ripple form being amplified as the output voltage is
increased. With a 10 μF bypass capacitor 75 dB ripple rejection is obtainable at any output
level. Increases over 20 μF do not appreciably improve the ripple rejection at frequencies
above 120 Hz. If the bypass capacitor is used, it is sometimes necessary to include
protection diodes to prevent the capacitor from discharging through internal low current
paths and damaging the device.
In general, the best type of capacitors to use are solid tantalum. Solid tantalum capacitors
have low impedance even at high frequencies. Depending upon capacitor construction, it
takes about 25 μF in aluminium electrolytic to equal 1 μF solid tantalum at high frequencies.
Ceramic capacitors are also good at high frequencies, but some types have a large

decrease in capacitance at frequencies around 0.5 MHz. For this reason, 0.01 μF disc may
seem to work better than a 0.1 μF disc as a bypass.
Although the LM350 is stable with no output capacitors, like any feedback circuit, certain
values of external capacitance can cause excessive ringing. This occurs with values
between 500 pF and 5000 pF. A 1 μF solid tantalum (or 25 μF aluminium electrolytic) on the
output swamps this effect and insures stability.
6.2 Load regulation
The LM350 is capable of providing extremely good load regulation but a few precautions are
needed to obtain maximum performance. The current set resistor connected between the
adjustment terminal and the output terminal (usually 240 Ω) should be tied directly to the
output of the regulator rather than near the load. This eliminates line drops from appearing
effectively in series with the reference and degrading regulation. For example, a 15 V
regulator with 0.05 Ω resistance between the regulator and load will have a load regulation
due to line resistance of 0.05 Ω x IL. If the set resistor is connected near the load the
effective line resistance will be 0.05 Ω (1 + R2/R1) or in this case, 11.5 times worse.
Figure 5 shows the effect of resistance between the regulator and 140 Ω set resistor. With
the TO-3 package, it is easy to minimize the resistance from the case to the set resistor, by
using 2 separate leads to the case. The ground of R2 can be returned near the ground of the
load to provide remote ground sensing and improve load regulation.
6.3 Protection diodes
When external capacitors are used with any IC regulator it is sometimes necessary to add
protection diodes to prevent the capacitors from discharging through low current points into
the regulator. Most 20 μF capacitors have low enough internal series resistance to deliver
20 A spikes when shorted. Although the surge is short, there is enough energy to damage
parts of the IC.
When an output capacitor is connected to a regulator and the input is shorted, the output
capacitor will discharge into the output of the regulator. The discharge current depends on
the value of the capacitor, the output voltage of the regulator, and the rate of decrease of VI.
In the LM350 this discharge path is through a large junction that is able to sustain 25 A
surge with no problem. This is not true of other types of positive regulators. For output
capacitors of 100 μF or less at output of 15 V or less, there is no need to use diodes.
The bypass capacitor on the adjustment terminal can discharge through a low current
junction. Discharge occurs when either the input or output is shorted. Internal to the LM350
is a 50 Ω resistor which limits the peak discharge current. No protection is needed for output
voltages of 25 V or less and 10 μF capacitance. Figure 6 shows an LM350 with protection
diodes included for use with outputs greater than 25 V and high values of output
capacitance.

Description
This circuit consists of two independent, high
gain, internally frequency-compensated
operational amplifiers designed specifically for
automotive and industrial control systems. It
operates from a single power supply over a wide
range of voltages. The low power supply drain is
independent of the magnitude of the power
supply voltage.
Application areas include transducer amplifiers,
DC gain blocks and all the conventional op-amp
circuits which can now be more easily
implemented in single power supply systems. For
example, these circuits can be directly supplied
from the standard +5 V which is used in logic
systems and easily provides the required
interface electronics without requiring any
additional power supply.
In the linear mode, the input common-mode
voltage range includes ground and the output
voltage can also swing to ground, even though
operated from a single power supply.

Output short-circuit duration (3)
3. Short-circuits from the output to VCC can cause excessive heating if Vcc+ > 15 V. The maximum output current is
approximately 40 mA, independent of the magnitude of VCC.
Destructive dissipation can result from simultaneous short-circuits on all amplifiers.
Infinite s
Iin
Input current (4): Vin driven negative
Input current (5): Vin driven positive above AMR value
4. This input current only exists when the voltage at any of the input leads is driven negative. It is due to the collector-base
junction of the input PNP transistor becoming forward-biased and thereby acting as input diode clamp. In addition to this
diode action, there is NPN parasitic action on the IC chip. This transistor action can cause the output voltages of the Opamps
to go to the VCC voltage level (or to ground for a large overdrive) for the time during which an input is driven negative.
This is not destructive and normal output is restored for input voltages above -0.3 V.
5. The junction base/substrate of the input PNP transistor polarized in reverse must be protected by a resistor in series with
the inputs to limit the input current to 400 μA max (R = (Vin-32 V)/400 μA).

1. VO = 1.4 V, RS = 0 W, 5 V < VCC+ < 30 V, 0 V < Vic < VCC+ - 1.5 V.
2. The direction of the input current is out of the IC. This current is essentially constant, independent of the state of the output,
so there is no change in the loading charge on the input lines.
3. The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than 0.3 V.
The upper end of the common-mode voltage range is VCC+ –1.5 V, but either or both inputs can go to +32 V without
damage.
4. Due to the proximity of external components, ensure that the stray capacitance does not cause coupling between these
external parts. This can typically be detected at higher frequencies because this type of capacitance increases.

5 Macromodel
An accurate macromodel of the LM2904 is available on STMicroelectronics’ web site at
www.st.com. This model is a trade-off between accuracy and complexity (that is, time
simulation) of the LM2904 operational amplifier. It emulates the nominal performances of a
typical device within the specified operating conditions mentioned in the datasheet. It also
helps to validate a design approach and to select the right operational amplifier, but it does
not replace on-board measurements.

LM217, LM317
1.2 V to 37 V adjustable voltage regulators
Datasheet - production data
Features
• Output voltage range: 1.2 to 37 V
• Output current in excess of 1.5 A
• 0.1 % line and load regulation
• Floating operation for high voltages
• Complete series of protections: current limiting,
thermal shutdown and SOA control
Description
The LM217, LM317 are monolithic integrated
circuits in TO-220, TO-220FP and D²PAK
packages intended for use as positive adjustable
voltage regulators. They are designed to supply
more than 1.5 A of load current with an output
voltage adjustable over a 1.2 to 37 V range. The
nominal output voltage is selected by means of a
resistive divider, making the device exceptionally
easy to use and eliminating the stocking of many
fixed regulators.

6 Application information
The LM217, LM317 provides an internal reference voltage of 1.25 V between the output and
adjustments terminals. This is used to set a constant current flow across an external resistor
divider (see Figure 6), giving an output voltage VO of:
VO = VREF (1 + R2/R1) + IADJ R2
The device was designed to minimize the term IADJ (100 μA max) and to maintain it very
constant with line and load changes. Usually, the error term IADJ × R2 can be neglected. To
obtain the previous requirement, all the regulator quiescent current is returned to the output
terminal, imposing a minimum load current condition. If the load is insufficient, the output
voltage will rise. Since the LM217, LM317 is a floating regulator and "sees" only the input-tooutput
differential voltage, supplies of very high voltage with respect to ground can be
regulated as long as the maximum input-to-output differential is not exceeded. Furthermore,
programmable regulators are easily obtainable and, by connecting a fixed resistor between
the adjustment and output, the device can be used as a precision current regulator. In order
to optimize the load regulation, the current set resistor R1 (see Figure 6) should be tied as
close as possible to the regulator, while the ground terminal of R2 should be near the ground
of the load to provide remote ground sensing. Performance may be improved with added
capacitance as follow:
• An input bypass capacitor of 0.1 μF
• An adjustment terminal to ground 10 μF capacitor to improve the ripple rejection of
about 15 dB (CADJ).
• An 1 μF tantalum (or 25 μF Aluminium electrolytic) capacitor on the output to improve
transient response. In addition to external capacitors, it is good practice to add
protection diodes, as shown in Figure 7 D1 protect the device against input short
circuit, while D2 protect against output short circuit for capacitance discharging.
Note: D1 protect the device against input short circuit, while D2 protects against output short
circuit for capacitors discharging.

STM32F20xxx Description
177
2 Description
The STM32F20x family is based on the high-performance ARM® Cortex™-M3 32-bit RISC
core operating at a frequency of up to 120 MHz. The family incorporates high-speed
embedded memories (Flash memory up to 1 Mbyte, up to 128 Kbytes of system SRAM), up
to 4 Kbytes of backup SRAM, and an extensive range of enhanced I/Os and peripherals
connected to two APB buses, three AHB buses and a 32-bit multi-AHB bus matrix.
The devices also feature an adaptive real-time memory accelerator (ART Accelerator™)
which allows to achieve a performance equivalent to 0 wait state program execution from
Flash memory at a CPU frequency up to 120 MHz. This performance has been validated
using the CoreMark benchmark.
All devices offer three 12-bit ADCs, two DACs, a low-power RTC, twelve general-purpose
16-bit timers including two PWM timers for motor control, two general-purpose 32-bit timers.
a true number random generator (RNG). They also feature standard and advanced
communication interfaces. New advanced peripherals include an SDIO, an enhanced
flexible static memory control (FSMC) interface (for devices offered in packages of 100 pins
and more), and a camera interface for CMOS sensors. The devices also feature standard
peripherals.
• Up to three I2Cs
• Three SPIs, two I2Ss. To achieve audio class accuracy, the I2S peripherals can be
clocked via a dedicated internal audio PLL or via an external PLL to allow
synchronization.
• 4 USARTs and 2 UARTs
• A USB OTG high-speed with full-speed capability (with the ULPI)
• A second USB OTG (full-speed)
• Two CANs
• An SDIO interface
• Ethernet and camera interface available on STM32F207xx devices only.
Note: The STM32F205xx and STM32F207xx devices operate in the –40 to +105 °C temperature
range from a 1.8 V to 3.6 V power supply. On devices in WLCSP64+2 package, if IRROFF
is set to VDD, the supply voltage can drop to 1.7 V when the device operates in the 0 to
70 °C temperature range using an external power supply supervisor (see Section 3.16).
A comprehensive set of power-saving modes allow the design of low-power applications.
STM32F205xx and STM32F207xx devices are offered in various packages ranging from 64
pins to 176 pins. The set of included peripherals changes with the device chosen.These
features make the STM32F205xx and STM32F207xx microcontroller family suitable for a
wide range of applications:
• Motor drive and application control
• Medical equipment
• Industrial applications: PLC, inverters, circuit breakers
• Printers, and scanners
• Alarm systems, video intercom, and HVAC
• Home audio appliances
Figure 4 shows the general block diagram of the device family.

STM32F20xxx Description

2.1 Full compatibility throughout the family
The STM32F205xx and STM32F207xx constitute the STM32F20x family whose members
are fully pin-to-pin, software and feature compatible, allowing the user to try different
memory densities and peripherals for a greater degree of freedom during the development
cycle.
The STM32F205xx and STM32F207xx devices maintain a close compatibility with the
whole STM32F10xxx family. All functional pins are pin-to-pin compatible. The
STM32F205xx and STM32F207xx, however, are not drop-in replacements for the
STM32F10xxx devices: the two families do not have the same power scheme, and so their
power pins are different. Nonetheless, transition from the STM32F10xxx to the STM32F20x
family remains simple as only a few pins are impacted.
Figure 3 and Figure 1 provide compatible board designs between the STM32F20x and the
STM32F10xxx family.

3 Functional overview
3.1 ARM® Cortex™-M3 core with embedded Flash and SRAM
The ARM Cortex-M3 processor is the latest generation of ARM processors for embedded
systems. It was developed to provide a low-cost platform that meets the needs of MCU
implementation, with a reduced pin count and low-power consumption, while delivering
outstanding computational performance and an advanced response to interrupts.
The ARM Cortex-M3 32-bit RISC processor features exceptional code-efficiency, delivering
the high-performance expected from an ARM core in the memory size usually associated
with 8- and 16-bit devices.
With its embedded ARM core, the STM32F20x family is compatible with all ARM tools and
software.
Figure 4 shows the general block diagram of the STM32F20x family.
3.2 Adaptive real-time memory accelerator (ART Accelerator™)
The ART Accelerator™ is a memory accelerator which is optimized for STM32 industrystandard
ARM® Cortex™-M3 processors. It balances the inherent performance advantage
of the ARM Cortex-M3 over Flash memory technologies, which normally requires the
processor to wait for the Flash memory at higher operating frequencies.
To release the processor full 150 DMIPS performance at this frequency, the accelerator
implements an instruction prefetch queue and branch cache which increases program
execution speed from the 128-bit Flash memory. Based on CoreMark benchmark, the
performance achieved thanks to the ART accelerator is equivalent to 0 wait state program
execution from Flash memory at a CPU frequency up to 120 MHz.
3.3 Memory protection unit
The memory protection unit (MPU) is used to manage the CPU accesses to memory to
prevent one task to accidentally corrupt the memory or resources used by any other active
task. This memory area is organized into up to 8 protected areas that can in turn be divided
up into 8 subareas. The protection area sizes are between 32 bytes and the whole 4
gigabytes of addressable memory.
The MPU is especially helpful for applications where some critical or certified code has to be
protected against the misbehavior of other tasks. It is usually managed by an RTOS (realtime
operating system). If a program accesses a memory location that is prohibited by the
MPU, the RTOS can detect it and take action. In an RTOS environment, the kernel can
dynamically update the MPU area setting, based on the process to be executed.
The MPU is optional and can be bypassed for applications that do not need it.

STM32F20xxx Functional overview

3.4 Embedded Flash memory
The STM32F20x devices embed a 128-bit wide Flash memory of 128 Kbytes, 256 Kbytes,
512 Kbytes, 768 Kbytes or 1 Mbytes available for storing programs and data.
The devices also feature 512 bytes of OTP memory that can be used to store critical user
data such as Ethernet MAC addresses or cryptographic keys.
3.5 CRC (cyclic redundancy check) calculation unit
The CRC (cyclic redundancy check) calculation unit is used to get a CRC code from a 32-bit
data word and a fixed generator polynomial.
Among other applications, CRC-based techniques are used to verify data transmission or
storage integrity. In the scope of the EN/IEC 60335-1 standard, they offer a means of
verifying the Flash memory integrity. The CRC calculation unit helps compute a software
signature during runtime, to be compared with a reference signature generated at link-time
and stored at a given memory location.
3.6 Embedded SRAM
All STM32F20x products embed:
• Up to 128 Kbytes of system SRAM accessed (read/write) at CPU clock speed with 0
wait states
• 4 Kbytes of backup SRAM.
The content of this area is protected against possible unwanted write accesses, and is
retained in Standby or VBAT mode.
3.7 Multi-AHB bus matrix
The 32-bit multi-AHB bus matrix interconnects all the masters (CPU, DMAs, Ethernet, USB
HS) and the slaves (Flash memory, RAM, FSMC, AHB and APB peripherals) and ensures a
seamless and efficient operation even when several high-speed peripherals work
simultaneously.
Functional overview STM32F20xxx
20/178 DocID15818 Rev 11
Figure 5. Multi-AHB matrix
3.8 DMA controller (DMA)
The devices feature two general-purpose dual-port DMAs (DMA1 and DMA2) with 8
streams each. They are able to manage memory-to-memory, peripheral-to-memory and
memory-to-peripheral transfers. They share some centralized FIFOs for APB/AHB
peripherals, support burst transfer and are designed to provide the maximum peripheral
bandwidth (AHB/APB).
The two DMA controllers support circular buffer management, so that no specific code is
needed when the controller reaches the end of the buffer. The two DMA controllers also
have a double buffering feature, which automates the use and switching of two memory
buffers without requiring any special code.
Each stream is connected to dedicated hardware DMA requests, with support for software
trigger on each stream. Configuration is made by software and transfer sizes between
source and destination are independent.

The DMA can be used with the main peripherals:
• SPI and I2S
• I2C
• USART and UART
• General-purpose, basic and advanced-control timers TIMx
• DAC
• SDIO
• Camera interface (DCMI)
• ADC.
3.9 Flexible static memory controller (FSMC)
The FSMC is embedded in all STM32F20x devices. It has four Chip Select outputs
supporting the following modes: PC Card/Compact Flash, SRAM, PSRAM, NOR Flash and
NAND Flash.
Functionality overview:
• Write FIFO
• Code execution from external memory except for NAND Flash and PC Card
• Maximum frequency (fHCLK) for external access is 60 MHz
LCD parallel interface
The FSMC can be configured to interface seamlessly with most graphic LCD controllers. It
supports the Intel 8080 and Motorola 6800 modes, and is flexible enough to adapt to
specific LCD interfaces. This LCD parallel interface capability makes it easy to build costeffective
graphic applications using LCD modules with embedded controllers or high
performance solutions using external controllers with dedicated acceleration.
3.10 Nested vectored interrupt controller (NVIC)
The STM32F20x devices embed a nested vectored interrupt controller able to manage 16
priority levels, and handle up to 81 maskable interrupt channels plus the 16 interrupt lines of
the Cortex™-M3.
The NVIC main features are the following:
• Closely coupled NVIC gives low-latency interrupt processing
• Interrupt entry vector table address passed directly to the core
• Closely coupled NVIC core interface
• Allows early processing of interrupts
• Processing of late arriving, higher-priority interrupts
• Support tail chaining
• Processor state automatically saved
• Interrupt entry restored on interrupt exit with no instruction overhead
This hardware block provides flexible interrupt management features with minimum interrupt
latency.
Functional overview STM32F20xxx
22/178 DocID15818 Rev 11
3.11 External interrupt/event controller (EXTI)
The external interrupt/event controller consists of 23 edge-detector lines used to generate
interrupt/event requests. Each line can be independently configured to select the trigger
event (rising edge, falling edge, both) and can be masked independently. A pending register
maintains the status of the interrupt requests. The EXTI can detect an external line with a
pulse width shorter than the Internal APB2 clock period. Up to 140 GPIOs can be connected
to the 16 external interrupt lines.
3.12 Clocks and startup
On reset the 16 MHz internal RC oscillator is selected as the default CPU clock. The
16 MHz internal RC oscillator is factory-trimmed to offer 1% accuracy. The application can
then select as system clock either the RC oscillator or an external 4-26 MHz clock source.
This clock is monitored for failure. If failure is detected, the system automatically switches
back to the internal RC oscillator and a software interrupt is generated (if enabled). Similarly,
full interrupt management of the PLL clock entry is available when necessary (for example if
an indirectly used external oscillator fails).
The advanced clock controller clocks the core and all peripherals using a single crystal or
oscillator. In particular, the ethernet and USB OTG FS peripherals can be clocked by the
system clock.
Several prescalers and PLLs allow the configuration of the three AHB buses, the highspeed
APB (APB2) and the low-speed APB (APB1) domains. The maximum frequency of
the three AHB buses is 120 MHz and the maximum frequency the high-speed APB domains
is 60 MHz. The maximum allowed frequency of the low-speed APB domain is 30 MHz.
The devices embed a dedicate PLL (PLLI2S) which allow to achieve audio class
performance. In this case, the I2S master clock can generate all standard sampling
frequencies from 8 kHz to 192 kHz.
3.13 Boot modes
At startup, boot pins are used to select one out of three boot options:
• Boot from user Flash
• Boot from system memory
• Boot from embedded SRAM
The boot loader is located in system memory. It is used to reprogram the Flash memory by
using USART1 (PA9/PA10), USART3 (PC10/PC11 or PB10/PB11), CAN2 (PB5/PB13), USB
OTG FS in Device mode (PA11/PA12) through DFU (device firmware upgrade).
3.14 Power supply schemes
• VDD = 1.8 to 3.6 V: external power supply for I/Os and the internal regulator (when
enabled), provided externally through VDD pins. On devices in WLCSP64+2 package, if
IRROFF is set to VDD, the supply voltage can drop to 1.7 V when the device operates
DocID15818 Rev 11 23/178
STM32F20xxx Functional overview
177
in the 0 to 70 °C temperature range using an external power supply supervisor (see
Section 3.16).
• VSSA, VDDA = 1.8 to 3.6 V: external analog power supplies for ADC, DAC, Reset
blocks, RCs and PLL. VDDA and VSSA must be connected to VDD and VSS, respectively.
• VBAT = 1.65 to 3.6 V: power supply for RTC, external clock, 32 kHz oscillator and
backup registers (through power switch) when VDD is not present.
Refer to Figure 19: Power supply scheme for more details.
3.15 Power supply supervisor
The devices have an integrated power-on reset (POR) / power-down reset (PDR) circuitry
coupled with a Brownout reset (BOR) circuitry.
At power-on, POR/PDR is always active and ensures proper operation starting from 1.8 V.
After the 1.8 V POR threshold level is reached, the option byte loading process starts, either
to confirm or modify default BOR threshold levels, or to disable BOR permanently. Three
BOR thresholds are available through option bytes.
The device remains in reset mode when VDD is below a specified threshold, VPOR/PDR or
VBOR, without the need for an external reset circuit. On devices in WLCSP64+2 package,
the BOR, POR and PDR features can be disabled by setting IRROFF pin to VDD. In this
mode an external power supply supervisor is required (see Section 3.16).
The devices also feature an embedded programmable voltage detector (PVD) that monitors
the VDD/VDDA power supply and compares it to the VPVD threshold. An interrupt can be
generated when VDD/VDDA drops below the VPVD threshold and/or when VDD/VDDA is
higher than the VPVD threshold. The interrupt service routine can then generate a warning
message and/or put the MCU into a safe state. The PVD is enabled by software.
3.16 Voltage regulator
The regulator has five operating modes:
• Regulator ON
– Main regulator mode (MR)
– Low power regulator (LPR)
– Power-down
• Regulator OFF
– Regulator OFF/internal reset ON
– Regulator OFF/internal reset OFF
3.16.1 Regulator ON
The regulator ON modes are activated by default on LQFP packages.On WLCSP64+2
package, they are activated by connecting both REGOFF and IRROFF pins to VSS, while
only REGOFF must be connected to VSS on UFBGA176 package (IRROFF is not available).
VDD minimum value is 1.8 V.
Functional overview STM32F20xxx
24/178 DocID15818 Rev 11
There are three power modes configured by software when the regulator is ON:
• MR is used in the nominal regulation mode
• LPR is used in Stop modes
The LP regulator mode is configured by software when entering Stop mode.
• Power-down is used in Standby mode.
The Power-down mode is activated only when entering Standby mode. The regulator
output is in high impedance and the kernel circuitry is powered down, inducing zero
consumption. The contents of the registers and SRAM are lost).
Two external ceramic capacitors should be connected on VCAP_1 and VCAP_2 pin. Refer to
Figure 19: Power supply scheme and Table 16: VCAP1/VCAP2 operating conditions.
All packages have the regulator ON feature.
3.16.2 Regulator OFF
This feature is available only on packages featuring the REGOFF pin. The regulator is
disabled by holding REGOFF high. The regulator OFF mode allows to supply externally a
V12 voltage source through VCAP_1 and VCAP_2 pins.
The two 2.2 μF ceramic capacitors should be replaced by two 100 nF decoupling
capacitors. Refer to Figure 19: Power supply scheme.
When the regulator is OFF, there is no more internal monitoring on V12. An external power
supply supervisor should be used to monitor the V12 of the logic power domain. PA0 pin
should be used for this purpose, and act as power-on reset on V12 power domain.
In regulator OFF mode, the following features are no more supported:
• PA0 cannot be used as a GPIO pin since it allows to reset the part of the 1.2 V logic
power domain which is not reset by the NRST pin.
• As long as PA0 is kept low, the debug mode cannot be used at power-on reset. As a
consequence, PA0 and NRST pins must be managed separately if the debug
connection at reset or pre-reset is required.
Regulator OFF/internal reset ON
On WLCSP64+2 package, this mode is activated by connecting REGOFF pin to VDD and
IRROFF pin to VSS. On UFBGA176 package, only REGOFF must be connected to VDD
(IRROFF not available). In this mode, VDD/VDDA minimum value is 1.8 V.
The regulator OFF/internal reset ON mode allows to supply externally a 1.2 V voltage
source through VCAP_1 and VCAP_2 pins, in addition to VDD.
DocID15818 Rev 11 25/178
STM32F20xxx Functional overview
177
Figure 6. Regulator OFF/internal reset ON
The following conditions must be respected:
• VDD should always be higher than VCAP_1 and VCAP_2 to avoid current injection
between power domains.
• If the time for VCAP_1 and VCAP_2 to reach 1.08 V is faster than the time for VDD to
reach 1.8 V, then PA0 should be kept low to cover both conditions: until VCAP_1 and
VCAP_2 reach 1.08 V and until VDD reaches 1.8 V (see Figure 8).
• Otherwise, If the time for VCAP_1 and VCAP_2 to reach 1.08 V is slower than the time for
VDD to reach 1.8 V, then PA0 should be asserted low externally (see Figure 9).
• If VCAP_1 and VCAP_2 go below 1.08 V and VDD is higher than 1.8 V, then a reset must
be asserted on PA0 pin.
Regulator OFF/internal reset OFF
On WLCSP64+2 package, this mode activated by connecting REGOFF to VSS and IRROFF
to VDD. IRROFF cannot be activated in conjunction with REGOFF. This mode is available
only on the WLCSP64+2 package. It allows to supply externally a 1.2 V voltage source
through VCAP_1 and VCAP_2 pins. In this mode, the integrated power-on reset (POR)/ powerdown
reset (PDR) circuitry is disabled.
An external power supply supervisor should monitor both the external 1.2 V and the external
VDD supply voltage, and should maintain the device in reset mode as long as they remain
below a specified threshold. The VDD specified threshold, below which the device must be
maintained under reset, is 1.8 V. This supply voltage can drop to 1.7 V when the device
operates in the 0 to 70 °C temperature range. A comprehensive set of power-saving modes
allows to design low-power applications.

• PA0 should be kept low to cover both conditions: until VCAP_1 and VCAP_2 reach 1.08 V,
and until VDD reaches 1.7 V.
• NRST should be controlled by an external reset controller to keep the device under
reset when VDD is below 1.7 V (see Figure 9).
In this mode, when the internal reset is OFF, the following integrated features are no more
supported:
• The integrated power-on reset (POR) / power-down reset (PDR) circuitry is disabled.
• The brownout reset (BOR) circuitry is disabled.
• The embedded programmable voltage detector (PVD) is disabled.
• VBAT functionality is no more available and VBAT pin should be connected to VDD.

3.17 Real-time clock (RTC), backup SRAM and backup registers
The backup domain of the STM32F20x devices includes:
• The real-time clock (RTC)
• 4 Kbytes of backup SRAM
• 20 backup registers
The real-time clock (RTC) is an independent BCD timer/counter. Its main features are the
following:
• Dedicated registers contain the second, minute, hour (in 12/24 hour), week day, date,
month, year, in BCD (binary-coded decimal) format.
• Automatic correction for 28, 29 (leap year), 30, and 31 day of the month.
• Programmable alarm and programmable periodic interrupts with wakeup from Stop and
Standby modes.
• It is clocked by a 32.768 kHz external crystal, resonator or oscillator, the internal lowpower
RC oscillator or the high-speed external clock divided by 128. The internal lowspeed
RC has a typical frequency of 32 kHz. The RTC can be calibrated using an
external 512 Hz output to compensate for any natural quartz deviation.
• Two alarm registers are used to generate an alarm at a specific time and calendar
fields can be independently masked for alarm comparison. To generate a periodic
interrupt, a 16-bit programmable binary auto-reload downcounter with programmable
resolution is available and allows automatic wakeup and periodic alarms from every
120 μs to every 36 hours.
• A 20-bit prescaler is used for the time base clock. It is by default configured to generate
a time base of 1 second from a clock at 32.768 kHz.
• Reference clock detection: a more precise second source clock (50 or 60 Hz) can be
used to enhance the calendar precision.
The 4-Kbyte backup SRAM is an EEPROM-like area.It can be used to store data which
need to be retained in VBAT and standby mode.This memory area is disabled to minimize
power consumption (see Section 3.18: Low-power modes). It can be enabled by software.

when VDD power is not present. Backup registers are not reset by a system, a power reset,
or when the device wakes up from the Standby mode (see Section 3.18: Low-power
modes).
Like backup SRAM, the RTC and backup registers are supplied through a switch that is
powered either from the VDD supply when present or the VBAT pin.
3.18 Low-power modes
The STM32F20x family supports three low-power modes to achieve the best compromise
between low power consumption, short startup time and available wakeup sources:
• Sleep mode
In Sleep mode, only the CPU is stopped. All peripherals continue to operate and can
wake up the CPU when an interrupt/event occurs.
• Stop mode
The Stop mode achieves the lowest power consumption while retaining the contents of
SRAM and registers. All clocks in the 1.2 V domain are stopped, the PLL, the HSI RC
and the HSE crystal oscillators are disabled. The voltage regulator can also be put
either in normal or in low-power mode.
The device can be woken up from the Stop mode by any of the EXTI line. The EXTI line
source can be one of the 16 external lines, the PVD output, the RTC alarm / wakeup /
tamper / time stamp events, the USB OTG FS/HS wakeup or the Ethernet wakeup.
• Standby mode
The Standby mode is used to achieve the lowest power consumption. The internal
voltage regulator is switched off so that the entire 1.2 V domain is powered off. The
PLL, the HSI RC and the HSE crystal oscillators are also switched off. After entering
Standby mode, the SRAM and register contents are lost except for registers in the
backup domain and the backup SRAM when selected.
The device exits the Standby mode when an external reset (NRST pin), an IWDG reset,
a rising edge on the WKUP pin, or an RTC alarm / wakeup / tamper /time stamp event
occurs.
Note: The RTC, the IWDG, and the corresponding clock sources are not stopped when the device
enters the Stop or Standby mode.
3.19 VBAT operation
The VBAT pin allows to power the device VBAT domain from an external battery or an
external supercapacitor.
VBAT operation is activated when VDD is not present.
The VBAT pin supplies the RTC, the backup registers and the backup SRAM.
Note: When the microcontroller is supplied from VBAT, external interrupts and RTC alarm/events
do not exit it from VBAT operation.
When using WLCSP64+2 package, if IRROFF pin is connected to VDD, the VBAT
functionality is no more available and VBAT pin should be connected to VDD.

3.20 Timers and watchdogs
The STM32F20x devices include two advanced-control timers, eight general-purpose
timers, two basic timers and two watchdog timers.
All timer counters can be frozen in debug mode.
Table 5 compares the features of the advanced-control, general-purpose and basic timers.
3.20.1 Advanced-control timers (TIM1, TIM8)
The advanced-control timers (TIM1, TIM8) can be seen as three-phase PWM generators
multiplexed on 6 channels. They have complementary PWM outputs with programmable
inserted dead times. They can also be considered as complete general-purpose timers.
Their 4 independent channels can be used for:
• Input capture
• Output compare
• PWM generation (edge- or center-aligned modes)
• One-pulse mode output

If configured as standard 16-bit timers, they have the same features as the general-purpose
TIMx timers. If configured as 16-bit PWM generators, they have full modulation capability (0-
100%).
The TIM1 and TIM8 counters can be frozen in debug mode. Many of the advanced-control
timer features are shared with those of the standard TIMx timers which have the same
architecture. The advanced-control timer can therefore work together with the TIMx timers
via the Timer Link feature for synchronization or event chaining.
3.20.2 General-purpose timers (TIMx)
There are ten synchronizable general-purpose timers embedded in the STM32F20x devices
(see Table 5 for differences).
TIM2, TIM3, TIM4, TIM5
The STM32F20x include 4 full-featured general-purpose timers. TIM2 and TIM5 are 32-bit
timers, and TIM3 and TIM4 are 16-bit timers. The TIM2 and TIM5 timers are based on a 32-
bit auto-reload up/downcounter and a 16-bit prescaler. The TIM3 and TIM4 timers are based
on a 16-bit auto-reload up/downcounter and a 16-bit prescaler. They all feature 4
independent channels for input capture/output compare, PWM or one-pulse mode output.
This gives up to 16 input capture/output compare/PWMs on the largest packages.
The TIM2, TIM3, TIM4, TIM5 general-purpose timers can work together, or with the other
general-purpose timers and the advanced-control timers TIM1 and TIM8 via the Timer Link
feature for synchronization or event chaining.
The counters of TIM2, TIM3, TIM4, TIM5 can be frozen in debug mode. Any of these
general-purpose timers can be used to generate PWM outputs.
TIM2, TIM3, TIM4, TIM5 all have independent DMA request generation. They are capable
of handling quadrature (incremental) encoder signals and the digital outputs from 1 to 4 halleffect
sensors.
TIM10, TIM11 and TIM9
These timers are based on a 16-bit auto-reload upcounter and a 16-bit prescaler. TIM10 and
TIM11 feature one independent channel, whereas TIM9 has two independent channels for
input capture/output compare, PWM or one-pulse mode output. They can be synchronized
with the TIM2, TIM3, TIM4, TIM5 full-featured general-purpose timers. They can also be
used as simple time bases.
TIM12, TIM13 and TIM14
These timers are based on a 16-bit auto-reload upcounter and a 16-bit prescaler. TIM13 and
TIM14 feature one independent channel, whereas TIM12 has two independent channels for
input capture/output compare, PWM or one-pulse mode output. They can be synchronized
with the TIM2, TIM3, TIM4, TIM5 full-featured general-purpose timers.
They can also be used as simple time bases.
3.20.3 Basic timers TIM6 and TIM7
These timers are mainly used for DAC trigger and waveform generation. They can also be
used as a generic 16-bit time base.
Functional overview STM32F20xxx
32/178 DocID15818 Rev 11
3.20.4 Independent watchdog
The independent watchdog is based on a 12-bit downcounter and 8-bit prescaler. It is
clocked from an independent 32 kHz internal RC and as it operates independently from the
main clock, it can operate in Stop and Standby modes. It can be used either as a watchdog
to reset the device when a problem occurs, or as a free-running timer for application timeout
management. It is hardware- or software-configurable through the option bytes.
The counter can be frozen in debug mode.
3.20.5 Window watchdog
The window watchdog is based on a 7-bit downcounter that can be set as free-running. It
can be used as a watchdog to reset the device when a problem occurs. It is clocked from
the main clock. It has an early warning interrupt capability and the counter can be frozen in
debug mode.
3.20.6 SysTick timer
This timer is dedicated to real-time operating systems, but could also be used as a standard
downcounter. It features:
• A 24-bit downcounter
• Autoreload capability
• Maskable system interrupt generation when the counter reaches 0
• Programmable clock source
3.21 Inter-integrated circuit interface (I²C)
Up to three I2C bus interfaces can operate in multimaster and slave modes. They can
support the Standard- and Fast-modes. They support the 7/10-bit addressing mode and the
7-bit dual addressing mode (as slave). A hardware CRC generation/verification is
embedded.
They can be served by DMA and they support SMBus 2.0/PMBus.
3.22 Universal synchronous/asynchronous receiver transmitters
(UARTs/USARTs)
The STM32F20x devices embed four universal synchronous/asynchronous receiver
transmitters (USART1, USART2, USART3 and USART6) and two universal asynchronous
receiver transmitters (UART4 and UART5).
These six interfaces provide asynchronous communication, IrDA SIR ENDEC support,
multiprocessor communication mode, single-wire half-duplex communication mode and
have LIN Master/Slave capability. The USART1 and USART6 interfaces are able to
communicate at speeds of up to 7.5 Mbit/s. The other available interfaces communicate at
up to 3.75 Mbit/s.
USART1, USART2, USART3 and USART6 also provide hardware management of the CTS
and RTS signals, Smart Card mode (ISO 7816 compliant) and SPI-like communication
capability. All interfaces can be served by the DMA controller.
DocID15818 Rev 11 33/178
STM32F20xxx Functional overview
177
3.23 Serial peripheral interface (SPI)
The STM32F20x devices feature up to three SPIs in slave and master modes in full-duplex
and simplex communication modes. SPI1 can communicate at up to 30 Mbits/s, while SPI2
and SPI3 can communicate at up to 15 Mbit/s. The 3-bit prescaler gives 8 master mode
frequencies and the frame is configurable to 8 bits or 16 bits. The hardware CRC
generation/verification supports basic SD Card/MMC modes. All SPIs can be served by the
DMA controller.
The SPI interface can be configured to operate in TI mode for communications in master
mode and slave mode.
3.24 Inter-integrated sound (I2S)
Two standard I2S interfaces (multiplexed with SPI2 and SPI3) are available. They can
operate in master or slave mode, in half-duplex communication modes, and can be
configured to operate with a 16-/32-bit resolution as input or output channels. Audio
sampling frequencies from 8 kHz up to 192 kHz are supported. When either or both of the
I2S interfaces is/are configured in master mode, the master clock can be output to the
external DAC/CODEC at 256 times the sampling frequency.
All I2Sx interfaces can be served by the DMA controller.
3.25 SDIO
An SD/SDIO/MMC host interface is available, that supports MultiMediaCard System
Specification Version 4.2 in three different databus modes: 1-bit (default), 4-bit and 8-bit.

The interface allows data transfer at up to 48 MHz in 8-bit mode, and is compliant with the
SD Memory Card Specification Version 2.0.
The SDIO Card Specification Version 2.0 is also supported with two different databus
modes: 1-bit (default) and 4-bit.
The current version supports only one SD/SDIO/MMC4.2 card at any one time and a stack
of MMC4.1 or previous.
In addition to SD/SDIO/MMC, this interface is fully compliant with the CE-ATA digital
protocol Rev1.1.
3.26 Ethernet MAC interface with dedicated DMA and IEEE 1588
support
Peripheral available only on the STM32F207xx devices.
The STM32F207xx devices provide an IEEE-802.3-2002-compliant media access controller
(MAC) for ethernet LAN communications through an industry-standard mediumindependent
interface (MII) or a reduced medium-independent interface (RMII). The
STM32F207xx requires an external physical interface device (PHY) to connect to the
physical LAN bus (twisted-pair, fiber, etc.). the PHY is connected to the STM32F207xx MII
port using 17 signals for MII or 9 signals for RMII, and can be clocked using the 25 MHz
(MII) or 50 MHz (RMII) output from the STM32F207xx.
The STM32F207xx includes the following features:
• Supports 10 and 100 Mbit/s rates
• Dedicated DMA controller allowing high-speed transfers between the dedicated SRAM
and the descriptors (see the STM32F20x and STM32F21x reference manual for
details)
• Tagged MAC frame support (VLAN support)
• Half-duplex (CSMA/CD) and full-duplex operation
• MAC control sublayer (control frames) support
• 32-bit CRC generation and removal
• Several address filtering modes for physical and multicast address (multicast and
group addresses)
• 32-bit status code for each transmitted or received frame
• Internal FIFOs to buffer transmit and receive frames. The transmit FIFO and the
receive FIFO are both 2 Kbytes, that is 4 Kbytes in total
• Supports hardware PTP (precision time protocol) in accordance with IEEE 1588 2008
(PTP V2) with the time stamp comparator connected to the TIM2 input
• Triggers interrupt when system time becomes greater than target time
3.27 Controller area network (CAN)
The two CANs are compliant with the 2.0A and B (active) specifications with a bitrate up to 1
Mbit/s. They can receive and transmit standard frames with 11-bit identifiers as well as
extended frames with 29-bit identifiers. Each CAN has three transmit mailboxes, two receive
FIFOS with 3 stages and 28 shared scalable filter banks (all of them can be used even if one

STM32F20xxx Functional overview
177
CAN is used). The 256 bytes of SRAM which are allocated for each CAN are not shared
with any other peripheral.
3.28 Universal serial bus on-the-go full-speed (OTG_FS)
The devices embed an USB OTG full-speed device/host/OTG peripheral with integrated
transceivers. The USB OTG FS peripheral is compliant with the USB 2.0 specification and
with the OTG 1.0 specification. It has software-configurable endpoint setting and supports
suspend/resume. The USB OTG full-speed controller requires a dedicated 48 MHz clock
that is generated by a PLL connected to the HSE oscillator. The major features are:
• Combined Rx and Tx FIFO size of 320 × 35 bits with dynamic FIFO sizing
• Supports the session request protocol (SRP) and host negotiation protocol (HNP)
• 4 bidirectional endpoints
• 8 host channels with periodic OUT support
• HNP/SNP/IP inside (no need for any external resistor)

3.29 Universal serial bus on-the-go high-speed (OTG_HS)
The STM32F20x devices embed a USB OTG high-speed (up to 480 Mb/s) device/host/OTG
peripheral. The USB OTG HS supports both full-speed and high-speed operations. It
integrates the transceivers for full-speed operation (12 MB/s) and features a UTMI low-pin
interface (ULPI) for high-speed operation (480 MB/s). When using the USB OTG HS in HS
mode, an external PHY device connected to the ULPI is required.
The USB OTG HS peripheral is compliant with the USB 2.0 specification and with the OTG
1.0 specification. It has software-configurable endpoint setting and supports
suspend/resume. The USB OTG full-speed controller requires a dedicated 48 MHz clock
that is generated by a PLL connected to the HSE oscillator. The major features are:
• Combined Rx and Tx FIFO size of 1024× 35 bits with dynamic FIFO sizing
• Supports the session request protocol (SRP) and host negotiation protocol (HNP)
• 6 bidirectional endpoints
• 12 host channels with periodic OUT support

connected to the microcontroller ULPI port through 12 signals. It can be clocked using
the 60 MHz output.
• Internal USB DMA
• HNP/SNP/IP inside (no need for any external resistor)
• For OTG/Host modes, a power switch is needed in case bus-powered devices are
connected

36/178 DocID15818 Rev 11
3.30 Audio PLL (PLLI2S)
The devices feature an additional dedicated PLL for audio I2S application. It allows to
achieve error-free I2S sampling clock accuracy without compromising on the CPU
performance, while using USB peripherals.
The PLLI2S configuration can be modified to manage an I2S sample rate change without
disabling the main PLL (PLL) used for CPU, USB and Ethernet interfaces.
The audio PLL can be programmed with very low error to obtain sampling rates ranging
from 8 kHz to 192 kHz.
In addition to the audio PLL, a master clock input pin can be used to synchronize the I2S
flow with an external PLL (or Codec output).
3.31 Digital camera interface (DCMI)
The camera interface is not available in STM32F205xx devices.
STM32F207xx products embed a camera interface that can connect with camera modules
and CMOS sensors through an 8-bit to 14-bit parallel interface, to receive video data. The
camera interface can sustain up to 27 Mbyte/s at 27 MHz or 48 Mbyte/s at 48 MHz. It
features:
• Programmable polarity for the input pixel clock and synchronization signals
• Parallel data communication can be 8-, 10-, 12- or 14-bit
• Supports 8-bit progressive video monochrome or raw Bayer format, YCbCr 4:2:2
progressive video, RGB 565 progressive video or compressed data (like JPEG)
• Supports continuous mode or snapshot (a single frame) mode
• Capability to automatically crop the image
3.32 True random number generator (RNG)
All STM32F2xxx products embed a true RNG that delivers 32-bit random numbers
produced by an integrated analog circuit.
3.33 GPIOs (general-purpose inputs/outputs)
Each of the GPIO pins can be configured by software as output (push-pull or open-drain,
with or without pull-up or pull-down), as input (floating, with or without pull-up or pull-down)
or as peripheral alternate function. Most of the GPIO pins are shared with digital or analog
alternate functions. All GPIOs are high-current-capable and have speed selection to better
manage internal noise, power consumption and electromagnetic emission.
The I/O alternate function configuration can be locked if needed by following a specific
sequence in order to avoid spurious writing to the I/Os registers.
To provide fast I/O handling, the GPIOs are on the fast AHB1 bus with a clock up to
120 MHz that leads to a maximum I/O toggling speed of 60 MHz.

3.34 ADCs (analog-to-digital converters)
Three 12-bit analog-to-digital converters are embedded and each ADC shares up to 16
external channels, performing conversions in the single-shot or scan mode. In scan mode,
automatic conversion is performed on a selected group of analog inputs.
Additional logic functions embedded in the ADC interface allow:
• Simultaneous sample and hold
• Interleaved sample and hold
The ADC can be served by the DMA controller. An analog watchdog feature allows very
precise monitoring of the converted voltage of one, some or all selected channels. An
interrupt is generated when the converted voltage is outside the programmed thresholds.
The events generated by the timers TIM1, TIM2, TIM3, TIM4, TIM5 and TIM8 can be
internally connected to the ADC start trigger and injection trigger, respectively, to allow the
application to synchronize A/D conversion and timers.
3.35 DAC (digital-to-analog converter)
The two 12-bit buffered DAC channels can be used to convert two digital signals into two
analog voltage signal outputs. The design structure is composed of integrated resistor
strings and an amplifier in inverting configuration.
This dual digital Interface supports the following features:
• two DAC converters: one for each output channel
• 8-bit or 12-bit monotonic output
• left or right data alignment in 12-bit mode
• synchronized update capability
• noise-wave generation
• triangular-wave generation
• dual DAC channel independent or simultaneous conversions
• DMA capability for each channel
• external triggers for conversion
• input voltage reference VREF+
Eight DAC trigger inputs are used in the device. The DAC channels are triggered through
the timer update outputs that are also connected to different DMA streams.
3.36 Temperature sensor
The temperature sensor has to generate a voltage that varies linearly with temperature. The
conversion range is between 1.8 and 3.6 V. The temperature sensor is internally connected
to the ADC1_IN16 input channel which is used to convert the sensor output voltage into a
digital value.
As the offset of the temperature sensor varies from chip to chip due to process variation, the
internal temperature sensor is mainly suitable for applications that detect temperature
changes instead of absolute temperatures. If an accurate temperature reading is needed,
then an external temperature sensor part should be used.

3.37 Serial wire JTAG debug port (SWJ-DP)
The ARM SWJ-DP interface is embedded, and is a combined JTAG and serial wire debug
port that enables either a serial wire debug or a JTAG probe to be connected to the target.
The JTAG TMS and TCK pins are shared with SWDIO and SWCLK, respectively, and a
specific sequence on the TMS pin is used to switch between JTAG-DP and SW-DP.
3.38 Embedded Trace Macrocell™
The ARM Embedded Trace Macrocell provides a greater visibility of the instruction and data
flow inside the CPU core by streaming compressed data at a very high rate from the
STM32F20x through a small number of ETM pins to an external hardware trace port
analyzer (TPA) device. The TPA is connected to a host computer using USB, Ethernet, or
any other high-speed channel. Real-time instruction and data flow activity can be recorded
and then formatted for display on the host computer that runs the debugger software. TPA
hardware is commercially available from common development tool vendors.
The Embedded Trace Macrocell operates with third party debugger software tools.

1. Function availability depends on the chosen device.
2. PC13, PC14, PC15 and PI8 are supplied through the power switch. Since the switch only sinks a limited amount of current
(3 mA), the use of GPIOs PC13 to PC15 and PI8 in output mode is limited: the speed should not exceed 2 MHz with a
maximum load of 30 pF and these I/Os must not be used as a current source (e.g. to drive an LED).
3. Main function after the first backup domain power-up. Later on, it depends on the contents of the RTC registers even after
reset (because these registers are not reset by the main reset). For details on how to manage these I/Os, refer to the RTC
register description sections in the STM32F20x and STM32F21x reference manual, available from the STMicroelectronics
website: www.st.com.
4. FT = 5 V tolerant except when in analog mode or oscillator mode (for PC14, PC15, PH0 and PH1).
5. If the device is delivered in an UFBGA176 package and if the REGOFF pin is set to VDD (Regulator OFF), then PA0 is
used as an internal Reset (active low).
6. FSMC_NL pin is also named FSMC_NADV on memory devices.
7. RFU means “reserved for future use”. This pin can be tied to VDD,VSS or left unconnected.

6 Electrical characteristics
6.1 Parameter conditions
Unless otherwise specified, all voltages are referenced to VSS.
6.1.1 Minimum and maximum values
Unless otherwise specified the minimum and maximum values are guaranteed in the worst
conditions of ambient temperature, supply voltage and frequencies by tests in production on
100% of the devices with an ambient temperature at TA = 25 °C and TA = TAmax (given by
the selected temperature range).
Data based on characterization results, design simulation and/or technology characteristics
are indicated in the table footnotes and are not tested in production. Based on
characterization, the minimum and maximum values refer to sample tests and represent the
mean value plus or minus three times the standard deviation (mean±3Σ).
6.1.2 Typical values
Unless otherwise specified, typical data are based on TA = 25 °C, VDD = 3.3 V (for the
1.8 V ≤ VDD ≤ 3.6 V voltage range). They are given only as design guidelines and are not
tested.
Typical ADC accuracy values are determined by characterization of a batch of samples from
a standard diffusion lot over the full temperature range, where 95% of the devices have an
error less than or equal to the value indicated (mean±2Σ).
6.1.3 Typical curves
Unless otherwise specified, all typical curves are given only as design guidelines and are
not tested.
6.1.4 Loading capacitor
The loading conditions used for pin parameter measurement are shown in Figure 17.
6.1.5 Pin input voltage
The input voltage measurement on a pin of the device is described in Figure 18.

6.1.6 Power supply scheme
Figure 19. Power supply scheme
1. Each power supply pair must be decoupled with filtering ceramic capacitors as shown above. These capacitors must be
placed as close as possible to, or below, the appropriate pins on the underside of the PCB to ensure the good functionality
of the device.
2. To connect REGOFF and IRROFF pins, refer to Section 3.16: Voltage regulator.
3. The two 2.2 μF ceramic capacitors should be replaced by two 100 nF decoupling capacitors when the voltage regulator is
OFF.
4. The 4.7 μF ceramic capacitor must be connected to one of the VDD pin.

On-chip peripheral current consumption
The current consumption of the on-chip peripherals is given in Table 26. The MCU is placed
under the following conditions:
• At startup, all I/O pins are configured as analog inputs by firmware.
• All peripherals are disabled unless otherwise mentioned
• The given value is calculated by measuring the current consumption
– with all peripherals clocked off
– with one peripheral clocked on (with only the clock applied)
• The code is running from Flash memory and the Flash memory access time is equal to
3 wait states at 120 MHz
• Prefetch and Cache ON
• When the peripherals are enabled, HCLK = 120MHz, fPCLK1 = fHCLK/4, and
fPCLK2 = fHCLK/2
• The typical values are obtained for VDD = 3.3 V and TA= 25 °C, unless otherwise
specified.

For CL1 and CL2, it is recommended to use high-quality external ceramic capacitors in the
5 pF to 25 pF range (typ.), designed for high-frequency applications, and selected to match
the requirements of the crystal or resonator (see Figure 32). CL1 and CL2 are usually the
same size. The crystal manufacturer typically specifies a load capacitance which is the
series combination of CL1 and CL2. PCB and MCU pin capacitance must be included (10 pF
can be used as a rough estimate of the combined pin and board capacitance) when sizing
CL1 and CL2.
Note: For information on electing the crystal, refer to the application note AN2867 “Oscillator
design guide for ST microcontrollers” available from the ST website www.st.com.

6.3.11 PLL spread spectrum clock generation (SSCG) characteristics
The spread spectrum clock generation (SSCG) feature allows to reduce electromagnetic
interferences (see Table 42: EMI characteristics). It is available only on the main PLL.
Equation 1
The frequency modulation period (MODEPER) is given by the equation below:
fPLL_IN and fMod must be expressed in Hz.
As an example:
If fPLL_IN = 1 MHz and fMOD = 1 kHz, the modulation depth (MODEPER) is given by equation
1:
Equation 2
Equation 2 allows to calculate the increment step (INCSTEP):
fVCO_OUT must be expressed in MHz.
With a modulation depth (md) = ±2 % (4 % peak to peak), and PLLN = 240 (in MHz):
An amplitude quantization error may be generated because the linear modulation profile is
obtained by taking the quantized values (rounded to the nearest integer) of MODPER and
INCSTEP. As a result, the achieved modulation depth is quantized. The percentage
quantized modulation depth is given by the following formula:
As a result:

Susceptibility tests are performed on a sample basis during device characterization.
Functional EMS (electromagnetic susceptibility)
While a simple application is executed on the device (toggling 2 LEDs through I/O ports).
the device is stressed by two electromagnetic events until a failure occurs. The failure is
indicated by the LEDs:
• Electrostatic discharge (ESD) (positive and negative) is applied to all device pins until
a functional disturbance occurs. This test is compliant with the IEC 61000-4-2 standard.
• FTB: A burst of fast transient voltage (positive and negative) is applied to VDD and VSS
through a 100 pF capacitor, until a functional disturbance occurs. This test is compliant
with the IEC 61000-4-4 standard.
A device reset allows normal operations to be resumed.

The test results are given in Table 41. They are based on the EMS levels and classes
defined in application note AN1709.
Designing hardened software to avoid noise problems
EMC characterization and optimization are performed at component level with a typical
application environment and simplified MCU software. It should be noted that good EMC
performance is highly dependent on the user application and the software in particular.
Therefore it is recommended that the user applies EMC software optimization and
prequalification tests in relation with the EMC level requested for his application.
Software recommendations
The software flowchart must include the management of runaway conditions such as:
• Corrupted program counter
• Unexpected reset
• Critical Data corruption (control registers...)
Prequalification trials
Most of the common failures (unexpected reset and program counter corruption) can be
reproduced by manually forcing a low state on the NRST pin or the Oscillator pins for 1
second.
To complete these trials, ESD stress can be applied directly on the device, over the range of
specification values. When unexpected behavior is detected, the software can be hardened
to prevent unrecoverable errors occurring (see application note AN1015).

Electromagnetic Interference (EMI)g
The electromagnetic field emitted by the device are monitored while a simple application,
executing EEMBC® code, is running. This emission test is compliant with SAE IEC61967-2
standard which specifies the test board and the pin loading.
6.3.14 Absolute maximum ratings (electrical sensitivity)
Based on three different tests (ESD, LU) using specific measurement methods, the device is
stressed in order to determine its performance in terms of electrical sensitivity.
Electrostatic discharge (ESD)
Electrostatic discharges (a positive then a negative pulse separated by 1 second) are
applied to the pins of each sample according to each pin combination. The sample size
depends on the number of supply pins in the device (3 parts × (n+1) supply pins). This test
conforms to the JESD22-A114/C101 standard.

Static latch-up
Two complementary static tests are required on six parts to assess the latch-up
performance:
• A supply overvoltage is applied to each power supply pin
• A current injection is applied to each input, output and configurable I/O pin
These tests are compliant with EIA/JESD 78A IC latch-up standard.
6.3.15 I/O current injection characteristics
As a general rule, current injection to the I/O pins, due to external voltage below VSS or
above VDD (for standard, 3 V-capable I/O pins) should be avoided during normal product
operation. However, in order to give an indication of the robustness of the microcontroller in
cases when abnormal injection accidentally happens, susceptibility tests are performed on a
sample basis during device characterization.
Functional susceptibilty to I/O current injection
While a simple application is executed on the device, the device is stressed by injecting
current into the I/O pins programmed in floating input mode. While current is injected into
the I/O pin, one at a time, the device is checked for functional failures.
The failure is indicated by an out of range parameter: ADC error above a certain limit (>5
LSB TUE), out of spec current injection on adjacent pins or other functional failure (for
example reset, oscillator frequency deviation).
The test results are given in Table 45.

Output driving current
The GPIOs (general purpose input/outputs) can sink or source up to ±8 mA, and sink or
source up to ±20 mA (with a relaxed VOL/VOH) except PC13, PC14 and PC15 which can
sink or source up to ±3mA. When using the PC13 to PC15 GPIOs in output mode, the
speed should not exceed 2 MHz with a maximum load of 30 pF.
In the user application, the number of I/O pins which can drive current must be limited to
respect the absolute maximum rating specified in Section 6.2:
• The sum of the currents sourced by all the I/Os on VDD, plus the maximum Run
consumption of the MCU sourced on VDD, cannot exceed the absolute maximum rating
IVDD (see Table 12).
• The sum of the currents sunk by all the I/Os on VSS plus the maximum Run
consumption of the MCU sunk on VSS cannot exceed the absolute maximum rating
IVSS (see Table 12).

6.3.17 NRST pin characteristics
The NRST pin input driver uses CMOS technology. It is connected to a permanent pull-up
resistor, RPU (see Table 49).
Unless otherwise specified, the parameters given in Table 49 are derived from tests
performed under the ambient temperature and VDD supply voltage conditions summarized
in Table 14.
Figure 39. Recommended NRST pin protection
1. The reset network protects the device against parasitic resets.
2. The user must ensure that the level on the NRST pin can go below the VIL(NRST) max level specified in
Table 49. Otherwise the reset is not taken into account by the device.

STM32F205xx and STM32F207xx I2C interface meets the requirements of the standard I2C
communication protocol with the following restrictions: the I/O pins SDA and SCL are
mapped to are not “true” open-drain. When configured as open-drain, the PMOS connected
between the I/O pin and VDD is disabled, but is still present.
The I2C characteristics are described in Table 52. Refer also to Section 6.3.16: I/O port

General PCB design guidelines
Power supply decoupling should be performed as shown in Figure 53 or Figure 54,
depending on whether VREF+ is connected to VDDA or not. The 10 nF capacitors should be
ceramic (good quality). They should be placed them as close as possible to the chip.

1. VREF+ and VREF– inputs are both available on UFBGA176 package. VREF+ is also available on all packages
except for LQFP64. When VREF+ and VREF– are not available, they are internally connected to VDDA and

7.2 Thermal characteristics
The maximum chip-junction temperature, TJ max, in degrees Celsius, may be calculated
using the following equation:
TJ max = TA max + (PD max x ΘJA)
Where:
• TA max is the maximum ambient temperature in °C,
• ΘJA is the package junction-to-ambient thermal resistance, in °C/W,
• PD max is the sum of PINT max and PI/O max (PD max = PINT max + PI/Omax),
• PINT max is the product of IDD and VDD, expressed in Watts. This is the maximum chip
internal power.
PI/O max represents the maximum power dissipation on output pins where:
PI/O max = Σ (VOL × IOL) + Σ((VDD – VOH) × IOH),
taking into account the actual VOL / IOL and VOH / IOH of the I/Os at low and high level in the
application.

2 Description
The STM32F405xx and STM32F407xx family is based on the high-performance ARM®
Cortex™-M4 32-bit RISC core operating at a frequency of up to 168 MHz. The Cortex-M4
core features a Floating point unit (FPU) single precision which supports all ARM singleprecision
data-processing instructions and data types. It also implements a full set of DSP
instructions and a memory protection unit (MPU) which enhances application security. The
Cortex-M4 core with FPU will be referred to as Cortex-M4F throughout this document.
The STM32F405xx and STM32F407xx family incorporates high-speed embedded
memories (Flash memory up to 1 Mbyte, up to 192 Kbytes of SRAM), up to 4 Kbytes of
backup SRAM, and an extensive range of enhanced I/Os and peripherals connected to two
APB buses, three AHB buses and a 32-bit multi-AHB bus matrix.
All devices offer three 12-bit ADCs, two DACs, a low-power RTC, twelve general-purpose
16-bit timers including two PWM timers for motor control, two general-purpose 32-bit timers.
a true random number generator (RNG). They also feature standard and advanced
communication interfaces.

STM32F405xx, STM32F407xx Description
2.1 Full compatibility throughout the family
The STM32F405xx and STM32F407xx are part of the STM32F4 family. They are fully pinto-
pin, software and feature compatible with the STM32F2xx devices, allowing the user to
try different memory densities, peripherals, and performances (FPU, higher frequency) for a
greater degree of freedom during the development cycle.
The STM32F405xx and STM32F407xx devices maintain a close compatibility with the
whole STM32F10xxx family. All functional pins are pin-to-pin compatible. The
STM32F405xx and STM32F407xx, however, are not drop-in replacements for the
STM32F10xxx devices: the two families do not have the same power scheme, and so their
power pins are different. Nonetheless, transition from the STM32F10xxx to the STM32F40x
family remains simple as only a few pins are impacted.
Figure 4, Figure 3, Figure 2, and Figure 1 give compatible board designs between the
STM32F40x, STM32F2xxx, and STM32F10xxx families.

STM32F405xx, STM32F407xx Description
2.2.1 ARM® Cortex™-M4F core with embedded Flash and SRAM
The ARM Cortex-M4F processor is the latest generation of ARM processors for embedded
systems. It was developed to provide a low-cost platform that meets the needs of MCU
implementation, with a reduced pin count and low-power consumption, while delivering
outstanding computational performance and an advanced response to interrupts.
The ARM Cortex-M4F 32-bit RISC processor features exceptional code-efficiency,
delivering the high-performance expected from an ARM core in the memory size usually
associated with 8- and 16-bit devices.
The processor supports a set of DSP instructions which allow efficient signal processing and
complex algorithm execution.
Its single precision FPU (floating point unit) speeds up software development by using
metalanguage development tools, while avoiding saturation.
The STM32F405xx and STM32F407xx family is compatible with all ARM tools and software.
Figure 5 shows the general block diagram of the STM32F40x family.
Note: Cortex-M4F is binary compatible with Cortex-M3.
2.2.2 Adaptive real-time memory accelerator (ART Accelerator™)
The ART Accelerator™ is a memory accelerator which is optimized for STM32 industrystandard
ARM® Cortex™-M4F processors. It balances the inherent performance advantage
of the ARM Cortex-M4F over Flash memory technologies, which normally requires the
processor to wait for the Flash memory at higher frequencies.
To release the processor full 210 DMIPS performance at this frequency, the accelerator
implements an instruction prefetch queue and branch cache, which increases program
execution speed from the 128-bit Flash memory. Based on CoreMark benchmark, the
performance achieved thanks to the ART accelerator is equivalent to 0 wait state program
execution from Flash memory at a CPU frequency up to 168 MHz.
2.2.3 Memory protection unit
The memory protection unit (MPU) is used to manage the CPU accesses to memory to
prevent one task to accidentally corrupt the memory or resources used by any other active
task. This memory area is organized into up to 8 protected areas that can in turn be divided
up into 8 subareas. The protection area sizes are between 32 bytes and the whole 4
gigabytes of addressable memory.
The MPU is especially helpful for applications where some critical or certified code has to be
protected against the misbehavior of other tasks. It is usually managed by an RTOS (realtime
operating system). If a program accesses a memory location that is prohibited by the
MPU, the RTOS can detect it and take action. In an RTOS environment, the kernel can
dynamically update the MPU area setting, based on the process to be executed.
The MPU is optional and can be bypassed for applications that do not need it.
2.2.4 Embedded Flash memory
The STM32F40x devices embed a Flash memory of 512 Kbytes or 1 Mbytes available for
storing programs and data.
Description STM32F405xx, STM32F407xx
20/185 DocID022152 Rev 4
2.2.5 CRC (cyclic redundancy check) calculation unit
The CRC (cyclic redundancy check) calculation unit is used to get a CRC code from a 32-bit
data word and a fixed generator polynomial.
Among other applications, CRC-based techniques are used to verify data transmission or
storage integrity. In the scope of the EN/IEC 60335-1 standard, they offer a means of
verifying the Flash memory integrity. The CRC calculation unit helps compute a software
signature during runtime, to be compared with a reference signature generated at link-time
and stored at a given memory location.
2.2.6 Embedded SRAM
All STM32F40x products embed:
• Up to 192 Kbytes of system SRAM including 64 Kbytes of CCM (core coupled memory)
data RAM
RAM memory is accessed (read/write) at CPU clock speed with 0 wait states.
• 4 Kbytes of backup SRAM
This area is accessible only from the CPU. Its content is protected against possible
unwanted write accesses, and is retained in Standby or VBAT mode.
2.2.7 Multi-AHB bus matrix
The 32-bit multi-AHB bus matrix interconnects all the masters (CPU, DMAs, Ethernet, USB
HS) and the slaves (Flash memory, RAM, FSMC, AHB and APB peripherals) and ensures a
seamless and efficient operation even when several high-speed peripherals work
simultaneously.
DocID022152 Rev 4 21/185
STM32F405xx, STM32F407xx Description
Figure 6. Multi-AHB matrix
2.2.8 DMA controller (DMA)
The devices feature two general-purpose dual-port DMAs (DMA1 and DMA2) with 8
streams each. They are able to manage memory-to-memory, peripheral-to-memory and
memory-to-peripheral transfers. They feature dedicated FIFOs for APB/AHB peripherals,
support burst transfer and are designed to provide the maximum peripheral bandwidth
(AHB/APB).
The two DMA controllers support circular buffer management, so that no specific code is
needed when the controller reaches the end of the buffer. The two DMA controllers also
have a double buffering feature, which automates the use and switching of two memory
buffers without requiring any special code.
Each stream is connected to dedicated hardware DMA requests, with support for software
trigger on each stream. Configuration is made by software and transfer sizes between
source and destination are independent.
The DMA can be used with the main peripherals:
• SPI and I2S
• I2C
• USART
• General-purpose, basic and advanced-control timers TIMx
• DAC
• SDIO
• Camera interface (DCMI)
• ADC.

2.2.9 Flexible static memory controller (FSMC)
The FSMC is embedded in the STM32F405xx and STM32F407xx family. It has four Chip
Select outputs supporting the following modes: PCCard/Compact Flash, SRAM, PSRAM,
NOR Flash and NAND Flash.
Functionality overview:
• Write FIFO
• Maximum FSMC_CLK frequency for synchronous accesses is 60 MHz.
LCD parallel interface
The FSMC can be configured to interface seamlessly with most graphic LCD controllers. It
supports the Intel 8080 and Motorola 6800 modes, and is flexible enough to adapt to
specific LCD interfaces. This LCD parallel interface capability makes it easy to build costeffective
graphic applications using LCD modules with embedded controllers or high
performance solutions using external controllers with dedicated acceleration.
2.2.10 Nested vectored interrupt controller (NVIC)
The STM32F405xx and STM32F407xx embed a nested vectored interrupt controller able to
manage 16 priority levels, and handle up to 82 maskable interrupt channels plus the 16
interrupt lines of the Cortex™-M4F.
• Closely coupled NVIC gives low-latency interrupt processing
• Interrupt entry vector table address passed directly to the core
• Allows early processing of interrupts
• Processing of late arriving, higher-priority interrupts
• Support tail chaining
• Processor state automatically saved
• Interrupt entry restored on interrupt exit with no instruction overhead
This hardware block provides flexible interrupt management features with minimum interrupt
latency.
2.2.11 External interrupt/event controller (EXTI)
The external interrupt/event controller consists of 23 edge-detector lines used to generate
interrupt/event requests. Each line can be independently configured to select the trigger
event (rising edge, falling edge, both) and can be masked independently. A pending register
maintains the status of the interrupt requests. The EXTI can detect an external line with a
pulse width shorter than the Internal APB2 clock period. Up to 140 GPIOs can be connected
to the 16 external interrupt lines.
2.2.12 Clocks and startup
On reset the 16 MHz internal RC oscillator is selected as the default CPU clock. The
16 MHz internal RC oscillator is factory-trimmed to offer 1% accuracy over the full
temperature range. The application can then select as system clock either the RC oscillator
or an external 4-26 MHz clock source. This clock can be monitored for failure. If a failure is
detected, the system automatically switches back to the internal RC oscillator and a
software interrupt is generated (if enabled). This clock source is input to a PLL thus allowing
to increase the frequency up to 168 MHz. Similarly, full interrupt management of the PLL

STM32F405xx, STM32F407xx Description
clock entry is available when necessary (for example if an indirectly used external oscillator
fails).
Several prescalers allow the configuration of the three AHB buses, the high-speed APB
(APB2) and the low-speed APB (APB1) domains. The maximum frequency of the three AHB
buses is 168 MHz while the maximum frequency of the high-speed APB domains is
84 MHz. The maximum allowed frequency of the low-speed APB domain is 42 MHz.
The devices embed a dedicated PLL (PLLI2S) which allows to achieve audio class
performance. In this case, the I2S master clock can generate all standard sampling
frequencies from 8 kHz to 192 kHz.
2.2.13 Boot modes
At startup, boot pins are used to select one out of three boot options:
• Boot from user Flash
• Boot from system memory
• Boot from embedded SRAM
The boot loader is located in system memory. It is used to reprogram the Flash memory by
using USART1 (PA9/PA10), USART3 (PC10/PC11 or PB10/PB11), CAN2 (PB5/PB13), USB
OTG FS in Device mode (PA11/PA12) through DFU (device firmware upgrade).
2.2.14 Power supply schemes
• VDD = 1.8 to 3.6 V: external power supply for I/Os and the internal regulator (when
enabled), provided externally through VDD pins.
• VSSA, VDDA = 1.8 to 3.6 V: external analog power supplies for ADC, DAC, Reset
blocks, RCs and PLL. VDDA and VSSA must be connected to VDD and VSS, respectively.
• VBAT = 1.65 to 3.6 V: power supply for RTC, external clock 32 kHz oscillator and
backup registers (through power switch) when VDD is not present.
Refer to Figure 21: Power supply scheme for more details.
Note: VDD/VDDA minimum value of 1.7 V is obtained when the device operates in reduced
temperature range, and with the use of an external power supply supervisor (refer to
Section : Internal reset OFF).
Refer to Table 2 in order to identify the packages supporting this option.
2.2.15 Power supply supervisor
Internal reset ON
On packages embedding the PDR_ON pin, the power supply supervisor is enabled by
holding PDR_ON high. On all other packages, the power supply supervisor is always
enabled.
The device has an integrated power-on reset (POR) / power-down reset (PDR) circuitry
coupled with a Brownout reset (BOR) circuitry. At power-on, POR/PDR is always active and
ensures proper operation starting from 1.8 V. After the 1.8 V POR threshold level is
reached, the option byte loading process starts, either to confirm or modify default BOR
threshold levels, or to disable BOR permanently. Three BOR thresholds are available
through option bytes. The device remains in reset mode when VDD is below a specified
threshold, VPOR/PDR or VBOR, without the need for an external reset circuit.
Description STM32F405xx, STM32F407xx
24/185 DocID022152 Rev 4
The device also features an embedded programmable voltage detector (PVD) that monitors
the VDD/VDDA power supply and compares it to the VPVD threshold. An interrupt can be
generated when VDD/VDDA drops below the VPVD threshold and/or when VDD/VDDA is
higher than the VPVD threshold. The interrupt service routine can then generate a warning
message and/or put the MCU into a safe state. The PVD is enabled by software.
Internal reset OFF
This feature is available only on packages featuring the PDR_ON pin. The internal power-on
reset (POR) / power-down reset (PDR) circuitry is disabled with the PDR_ON pin.
An external power supply supervisor should monitor VDD and should maintain the device in
reset mode as long as VDD is below a specified threshold. PDR_ON should be connected to
this external power supply supervisor. Refer to Figure 7: Power supply supervisor
interconnection with internal reset OFF.
Figure 7. Power supply supervisor interconnection with internal reset OFF
1. PDR = 1.7 V for reduce temperature range; PDR = 1.8 V for all temperature range.
The VDD specified threshold, below which the device must be maintained under reset, is
1.8 V (see Figure 7). This supply voltage can drop to 1.7 V when the device operates in the
0 to 70 °C temperature range.
A comprehensive set of power-saving mode allows to design low-power applications.
When the internal reset is OFF, the following integrated features are no more supported:
• The integrated power-on reset (POR) / power-down reset (PDR) circuitry is disabled
• The brownout reset (BOR) circuitry is disabled
• The embedded programmable voltage detector (PVD) is disabled
• VBAT functionality is no more available and VBAT pin should be connected to VDD
All packages, except for the LQFP64 and LQFP100, allow to disable the internal reset
through the PDR_ON signal.

2.2.16 Voltage regulator
The regulator has four operating modes:
• Regulator ON
– Main regulator mode (MR)
– Low power regulator (LPR)
– Power-down
• Regulator OFF
Regulator ON
On packages embedding the BYPASS_REG pin, the regulator is enabled by holding
BYPASS_REG low. On all other packages, the regulator is always enabled.
There are three power modes configured by software when regulator is ON:
• MR is used in the nominal regulation mode (With different voltage scaling in Run)
In Main regulator mode (MR mode), different voltage scaling are provided to reach the
best compromise between maximum frequency and dynamic power consumption.
Refer to Table 14: General operating conditions.
• LPR is used in the Stop modes
The LP regulator mode is configured by software when entering Stop mode.
• Power-down is used in Standby mode.
The Power-down mode is activated only when entering in Standby mode. The regulator
output is in high impedance and the kernel circuitry is powered down, inducing zero
consumption. The contents of the registers and SRAM are lost)

Two external ceramic capacitors should be connected on VCAP_1 & VCAP_2 pin. Refer to
Figure 21: Power supply scheme and Figure 16: VCAP_1/VCAP_2 operating conditions.
All packages have regulator ON feature.
Regulator OFF
This feature is available only on packages featuring the BYPASS_REG pin. The regulator is
disabled by holding BYPASS_REG high. The regulator OFF mode allows to supply
externally a V12 voltage source through VCAP_1 and VCAP_2 pins.
Since the internal voltage scaling is not manage internally, the external voltage value must
be aligned with the targetted maximum frequency. Refer to Table 14: General operating
conditions.
The two 2.2 μF ceramic capacitors should be replaced by two 100 nF decoupling
capacitors.
Refer to Figure 21: Power supply scheme
When the regulator is OFF, there is no more internal monitoring on V12. An external power
supply supervisor should be used to monitor the V12 of the logic power domain. PA0 pin
should be used for this purpose, and act as power-on reset on V12 power domain.
In regulator OFF mode the following features are no more supported:
• PA0 cannot be used as a GPIO pin since it allows to reset a part of the V12 logic power
domain which is not reset by the NRST pin.
• As long as PA0 is kept low, the debug mode cannot be used under power-on reset. As
a consequence, PA0 and NRST pins must be managed separately if the debug
connection under reset or pre-reset is required.

STM32F405xx, STM32F407xx Description
The following conditions must be respected:
• VDD should always be higher than VCAP_1 and VCAP_2 to avoid current injection
between power domains.
• If the time for VCAP_1 and VCAP_2 to reach V12 minimum value is faster than the time for
VDD to reach 1.8 V, then PA0 should be kept low to cover both conditions: until VCAP_1
and VCAP_2 reach V12 minimum value and until VDD reaches 1.8 V (see Figure 10).
• Otherwise, if the time for VCAP_1 and VCAP_2 to reach V12 minimum value is slower
than the time for VDD to reach 1.8 V, then PA0 could be asserted low externally (see
Figure 11).
• If VCAP_1 and VCAP_2 go below V12 minimum value and VDD is higher than 1.8 V, then
a reset must be asserted on PA0 pin.
Note: The minimum value of V12 depends on the maximum frequency targeted in the application
(see Table 14: General operating conditions).

2.2.18 Real-time clock (RTC), backup SRAM and backup registers
The backup domain of the STM32F405xx and STM32F407xx includes:
• The real-time clock (RTC)
• 4 Kbytes of backup SRAM
• 20 backup registers
The real-time clock (RTC) is an independent BCD timer/counter. Dedicated registers contain
the second, minute, hour (in 12/24 hour), week day, date, month, year, in BCD (binarycoded
decimal) format. Correction for 28, 29 (leap year), 30, and 31 day of the month are
performed automatically. The RTC provides a programmable alarm and programmable
periodic interrupts with wakeup from Stop and Standby modes. The sub-seconds value is
also available in binary format.
It is clocked by a 32.768 kHz external crystal, resonator or oscillator, the internal low-power
RC oscillator or the high-speed external clock divided by 128. The internal low-speed RC

has a typical frequency of 32 kHz. The RTC can be calibrated using an external 512 Hz
output to compensate for any natural quartz deviation.
Two alarm registers are used to generate an alarm at a specific time and calendar fields can
be independently masked for alarm comparison. To generate a periodic interrupt, a 16-bit
programmable binary auto-reload downcounter with programmable resolution is available
and allows automatic wakeup and periodic alarms from every 120 μs to every 36 hours.
A 20-bit prescaler is used for the time base clock. It is by default configured to generate a
time base of 1 second from a clock at 32.768 kHz.
The 4-Kbyte backup SRAM is an EEPROM-like memory area. It can be used to store data
which need to be retained in VBAT and standby mode. This memory area is disabled by
default to minimize power consumption (see Section 2.2.19: Low-power modes). It can be
enabled by software.
The backup registers are 32-bit registers used to store 80 bytes of user application data
when VDD power is not present. Backup registers are not reset by a system, a power reset,
or when the device wakes up from the Standby mode (see Section 2.2.19: Low-power
modes).
Additional 32-bit registers contain the programmable alarm subseconds, seconds, minutes,
hours, day, and date.
Like backup SRAM, the RTC and backup registers are supplied through a switch that is
powered either from the VDD supply when present or from the VBAT pin.
2.2.19 Low-power modes
The STM32F405xx and STM32F407xx support three low-power modes to achieve the best
compromise between low power consumption, short startup time and available wakeup
sources:
• Sleep mode
In Sleep mode, only the CPU is stopped. All peripherals continue to operate and can
wake up the CPU when an interrupt/event occurs.
• Stop mode
The Stop mode achieves the lowest power consumption while retaining the contents of
SRAM and registers. All clocks in the V12 domain are stopped, the PLL, the HSI RC
and the HSE crystal oscillators are disabled. The voltage regulator can also be put
either in normal or in low-power mode.
The device can be woken up from the Stop mode by any of the EXTI line (the EXTI line
source can be one of the 16 external lines, the PVD output, the RTC alarm / wakeup /
tamper / time stamp events, the USB OTG FS/HS wakeup or the Ethernet wakeup).
• Standby mode
The Standby mode is used to achieve the lowest power consumption. The internal
voltage regulator is switched off so that the entire V12 domain is powered off. The PLL,
the HSI RC and the HSE crystal oscillators are also switched off. After entering
Description STM32F405xx, STM32F407xx
30/185 DocID022152 Rev 4
Standby mode, the SRAM and register contents are lost except for registers in the
backup domain and the backup SRAM when selected.
The device exits the Standby mode when an external reset (NRST pin), an IWDG reset,
a rising edge on the WKUP pin, or an RTC alarm / wakeup / tamper /time stamp event
occurs.
The standby mode is not supported when the embedded voltage regulator is bypassed
and the V12 domain is controlled by an external power.
2.2.20 VBAT operation
The VBAT pin allows to power the device VBAT domain from an external battery, an external
supercapacitor, or from VDD when no external battery and an external supercapacitor are
present.
VBAT operation is activated when VDD is not present.
The VBAT pin supplies the RTC, the backup registers and the backup SRAM.
Note: When the microcontroller is supplied from VBAT, external interrupts and RTC alarm/events
do not exit it from VBAT operation.
When PDR_ON pin is not connected to VDD (internal reset OFF), the VBAT functionality is no
more available and VBAT pin should be connected to VDD.
2.2.21 Timers and watchdogs
The STM32F405xx and STM32F407xx devices include two advanced-control timers, eight
general-purpose timers, two basic timers and two watchdog timers.
All timer counters can be frozen in debug mode.
Table 4 compares the features of the advanced-control, general-purpose and basic timers.

Advanced-control timers (TIM1, TIM8)
The advanced-control timers (TIM1, TIM8) can be seen as three-phase PWM generators
multiplexed on 6 channels. They have complementary PWM outputs with programmable
inserted dead times. They can also be considered as complete general-purpose timers.
Their 4 independent channels can be used for:
• Input capture
• Output compare
• PWM generation (edge- or center-aligned modes)
• One-pulse mode output
If configured as standard 16-bit timers, they have the same features as the general-purpose
TIMx timers. If configured as 16-bit PWM generators, they have full modulation capability (0-
100%).
The advanced-control timer can work together with the TIMx timers via the Timer Link
feature for synchronization or event chaining.
TIM1 and TIM8 support independent DMA request generation.

General-purpose timers (TIMx)
There are ten synchronizable general-purpose timers embedded in the STM32F40x devices
(see Table 4 for differences).
• TIM2, TIM3, TIM4, TIM5
The STM32F40x include 4 full-featured general-purpose timers: TIM2, TIM5, TIM3,
and TIM4.The TIM2 and TIM5 timers are based on a 32-bit auto-reload
up/downcounter and a 16-bit prescaler. The TIM3 and TIM4 timers are based on a 16-
bit auto-reload up/downcounter and a 16-bit prescaler. They all feature 4 independent
channels for input capture/output compare, PWM or one-pulse mode output. This gives
up to 16 input capture/output compare/PWMs on the largest packages.
The TIM2, TIM3, TIM4, TIM5 general-purpose timers can work together, or with the
other general-purpose timers and the advanced-control timers TIM1 and TIM8 via the
Timer Link feature for synchronization or event chaining.
Any of these general-purpose timers can be used to generate PWM outputs.
TIM2, TIM3, TIM4, TIM5 all have independent DMA request generation. They are
capable of handling quadrature (incremental) encoder signals and the digital outputs
from 1 to 4 hall-effect sensors.
• TIM9, TIM10, TIM11, TIM12, TIM13, and TIM14
These timers are based on a 16-bit auto-reload upcounter and a 16-bit prescaler.
TIM10, TIM11, TIM13, and TIM14 feature one independent channel, whereas TIM9
and TIM12 have two independent channels for input capture/output compare, PWM or
one-pulse mode output. They can be synchronized with the TIM2, TIM3, TIM4, TIM5
full-featured general-purpose timers. They can also be used as simple time bases.
Basic timers TIM6 and TIM7
These timers are mainly used for DAC trigger and waveform generation. They can also be
used as a generic 16-bit time base.
TIM6 and TIM7 support independent DMA request generation.
Independent watchdog
The independent watchdog is based on a 12-bit downcounter and 8-bit prescaler. It is
clocked from an independent 32 kHz internal RC and as it operates independently from the
main clock, it can operate in Stop and Standby modes. It can be used either as a watchdog
to reset the device when a problem occurs, or as a free-running timer for application timeout
management. It is hardware- or software-configurable through the option bytes.
Window watchdog
The window watchdog is based on a 7-bit downcounter that can be set as free-running. It
can be used as a watchdog to reset the device when a problem occurs. It is clocked from
the main clock. It has an early warning interrupt capability and the counter can be frozen in
debug mode.

STM32F405xx, STM32F407xx Description
SysTick timer
This timer is dedicated to real-time operating systems, but could also be used as a standard
downcounter. It features:
• A 24-bit downcounter
• Autoreload capability
• Maskable system interrupt generation when the counter reaches 0
• Programmable clock source.
2.2.22 Inter-integrated circuit interface (I²C)
Up to three I²C bus interfaces can operate in multimaster and slave modes. They can
support the Standard-mode (up to 100 kHz) and Fast-mode (up to 400 kHz) . They support
the 7/10-bit addressing mode and the 7-bit dual addressing mode (as slave). A hardware
CRC generation/verification is embedded.
They can be served by DMA and they support SMBus 2.0/PMBus.
2.2.23 Universal synchronous/asynchronous receiver transmitters (USART)
The STM32F405xx and STM32F407xx embed four universal synchronous/asynchronous
receiver transmitters (USART1, USART2, USART3 and USART6) and two universal
asynchronous receiver transmitters (UART4 and UART5).
These six interfaces provide asynchronous communication, IrDA SIR ENDEC support,
multiprocessor communication mode, single-wire half-duplex communication mode and
have LIN Master/Slave capability. The USART1 and USART6 interfaces are able to
communicate at speeds of up to 10.5 Mbit/s. The other available interfaces communicate at
up to 5.25 Mbit/s.
USART1, USART2, USART3 and USART6 also provide hardware management of the CTS
and RTS signals, Smart Card mode (ISO 7816 compliant) and SPI-like communication
capability. All interfaces can be served by the DMA controller.
Description STM32F405xx, STM32F407xx
34/185 DocID022152 Rev 4
2.2.24 Serial peripheral interface (SPI)
The STM32F40x feature up to three SPIs in slave and master modes in full-duplex and
simplex communication modes. SPI1 can communicate at up to 42 Mbits/s, SPI2 and SPI3
can communicate at up to 21 Mbit/s. The 3-bit prescaler gives 8 master mode frequencies
and the frame is configurable to 8 bits or 16 bits. The hardware CRC generation/verification
supports basic SD Card/MMC modes. All SPIs can be served by the DMA controller.
The SPI interface can be configured to operate in TI mode for communications in master
mode and slave mode.
2.2.25 Inter-integrated sound (I2S)
Two standard I2S interfaces (multiplexed with SPI2 and SPI3) are available. They can be
operated in master or slave mode, in full duplex and half-duplex communication modes, and
can be configured to operate with a 16-/32-bit resolution as an input or output channel.
Audio sampling frequencies from 8 kHz up to 192 kHz are supported. When either or both of
the I2S interfaces is/are configured in master mode, the master clock can be output to the
external DAC/CODEC at 256 times the sampling frequency.
All I2Sx can be served by the DMA controller.
2.2.26 Audio PLL (PLLI2S)
The devices feature an additional dedicated PLL for audio I2S application. It allows to
achieve error-free I2S sampling clock accuracy without compromising on the CPU
performance, while using USB peripherals.

STM32F405xx, STM32F407xx Description
The PLLI2S configuration can be modified to manage an I2S sample rate change without
disabling the main PLL (PLL) used for CPU, USB and Ethernet interfaces.
The audio PLL can be programmed with very low error to obtain sampling rates ranging
from 8 KHz to 192 KHz.
In addition to the audio PLL, a master clock input pin can be used to synchronize the I2S
flow with an external PLL (or Codec output).
2.2.27 Secure digital input/output interface (SDIO)
An SD/SDIO/MMC host interface is available, that supports MultiMediaCard System
Specification Version 4.2 in three different databus modes: 1-bit (default), 4-bit and 8-bit.
The interface allows data transfer at up to 48 MHz, and is compliant with the SD Memory
Card Specification Version 2.0.
The SDIO Card Specification Version 2.0 is also supported with two different databus
modes: 1-bit (default) and 4-bit.
The current version supports only one SD/SDIO/MMC4.2 card at any one time and a stack
of MMC4.1 or previous.
In addition to SD/SDIO/MMC, this interface is fully compliant with the CE-ATA digital
protocol Rev1.1.
2.2.28 Ethernet MAC interface with dedicated DMA and IEEE 1588 support
Peripheral available only on the STM32F407xx devices.
The STM32F407xx devices provide an IEEE-802.3-2002-compliant media access controller
(MAC) for ethernet LAN communications through an industry-standard mediumindependent
interface (MII) or a reduced medium-independent interface (RMII). The
STM32F407xx requires an external physical interface device (PHY) to connect to the
physical LAN bus (twisted-pair, fiber, etc.). the PHY is connected to the STM32F407xx MII
port using 17 signals for MII or 9 signals for RMII, and can be clocked using the 25 MHz
(MII) from the STM32F407xx.
The STM32F407xx includes the following features:
• Supports 10 and 100 Mbit/s rates
• Dedicated DMA controller allowing high-speed transfers between the dedicated SRAM
and the descriptors (see the STM32F40x reference manual for details)
• Tagged MAC frame support (VLAN support)
• Half-duplex (CSMA/CD) and full-duplex operation
• MAC control sublayer (control frames) support
• 32-bit CRC generation and removal
• Several address filtering modes for physical and multicast address (multicast and
group addresses)
• 32-bit status code for each transmitted or received frame
• Internal FIFOs to buffer transmit and receive frames. The transmit FIFO and the
receive FIFO are both 2 Kbytes.
• Supports hardware PTP (precision time protocol) in accordance with IEEE 1588 2008

2.2.29 Controller area network (bxCAN)
The two CANs are compliant with the 2.0A and B (active) specifications with a bitrate up to 1
Mbit/s. They can receive and transmit standard frames with 11-bit identifiers as well as
extended frames with 29-bit identifiers. Each CAN has three transmit mailboxes, two receive
FIFOS with 3 stages and 28 shared scalable filter banks (all of them can be used even if one
CAN is used). 256 bytes of SRAM are allocated for each CAN.
2.2.30 Universal serial bus on-the-go full-speed (OTG_FS)
The STM32F405xx and STM32F407xx embed an USB OTG full-speed device/host/OTG
peripheral with integrated transceivers. The USB OTG FS peripheral is compliant with the
USB 2.0 specification and with the OTG 1.0 specification. It has software-configurable
endpoint setting and supports suspend/resume. The USB OTG full-speed controller
requires a dedicated 48 MHz clock that is generated by a PLL connected to the HSE
oscillator. The major features are:
• Combined Rx and Tx FIFO size of 320 × 35 bits with dynamic FIFO sizing
• Supports the session request protocol (SRP) and host negotiation protocol (HNP)
• 4 bidirectional endpoints
• 8 host channels with periodic OUT support
• HNP/SNP/IP inside (no need for any external resistor)
• For OTG/Host modes, a power switch is needed in case bus-powered devices are
connected
2.2.31 Universal serial bus on-the-go high-speed (OTG_HS)
The STM32F405xx and STM32F407xx devices embed a USB OTG high-speed (up to
480 Mb/s) device/host/OTG peripheral. The USB OTG HS supports both full-speed and
high-speed operations. It integrates the transceivers for full-speed operation (12 MB/s) and
features a UTMI low-pin interface (ULPI) for high-speed operation (480 MB/s). When using
the USB OTG HS in HS mode, an external PHY device connected to the ULPI is required.
The USB OTG HS peripheral is compliant with the USB 2.0 specification and with the OTG
1.0 specification. It has software-configurable endpoint setting and supports
suspend/resume. The USB OTG full-speed controller requires a dedicated 48 MHz clock
that is generated by a PLL connected to the HSE oscillator.
The major features are:
• Combined Rx and Tx FIFO size of 1 Kbit × 35 with dynamic FIFO sizing
• Supports the session request protocol (SRP) and host negotiation protocol (HNP)
• 6 bidirectional endpoints
• 12 host channels with periodic OUT support
• Internal FS OTG PHY support
• External HS or HS OTG operation supporting ULPI in SDR mode. The OTG PHY is
connected to the microcontroller ULPI port through 12 signals. It can be clocked using
the 60 MHz output.
• Internal USB DMA
• HNP/SNP/IP inside (no need for any external resistor)
• for OTG/Host modes, a power switch is needed in case bus-powered devices are
connected

STM32F405xx, STM32F407xx Description
2.2.32 Digital camera interface (DCMI)
The camera interface is not available in STM32F405xx devices.
STM32F407xx products embed a camera interface that can connect with camera modules
and CMOS sensors through an 8-bit to 14-bit parallel interface, to receive video data. The
camera interface can sustain a data transfer rate up to 54 Mbyte/s at 54 MHz. It features:
• Programmable polarity for the input pixel clock and synchronization signals
• Parallel data communication can be 8-, 10-, 12- or 14-bit
• Supports 8-bit progressive video monochrome or raw bayer format, YCbCr 4:2:2
progressive video, RGB 565 progressive video or compressed data (like JPEG)
• Supports continuous mode or snapshot (a single frame) mode
• Capability to automatically crop the image
2.2.33 Random number generator (RNG)
All STM32F405xx and STM32F407xx products embed an RNG that delivers 32-bit random
numbers generated by an integrated analog circuit.
2.2.34 General-purpose input/outputs (GPIOs)
Each of the GPIO pins can be configured by software as output (push-pull or open-drain,
with or without pull-up or pull-down), as input (floating, with or without pull-up or pull-down)
or as peripheral alternate function. Most of the GPIO pins are shared with digital or analog
alternate functions. All GPIOs are high-current-capable and have speed selection to better
manage internal noise, power consumption and electromagnetic emission.
The I/O configuration can be locked if needed by following a specific sequence in order to
avoid spurious writing to the I/Os registers.
Fast I/O handling allowing maximum I/O toggling up to 84 MHz.
2.2.35 Analog-to-digital converters (ADCs)
Three 12-bit analog-to-digital converters are embedded and each ADC shares up to 16
external channels, performing conversions in the single-shot or scan mode. In scan mode,
automatic conversion is performed on a selected group of analog inputs.
Additional logic functions embedded in the ADC interface allow:
• Simultaneous sample and hold
• Interleaved sample and hold
The ADC can be served by the DMA controller. An analog watchdog feature allows very
precise monitoring of the converted voltage of one, some or all selected channels. An
interrupt is generated when the converted voltage is outside the programmed thresholds.
To synchronize A/D conversion and timers, the ADCs could be triggered by any of TIM1,
TIM2, TIM3, TIM4, TIM5, or TIM8 timer.
2.2.36 Temperature sensor
The temperature sensor has to generate a voltage that varies linearly with temperature. The
conversion range is between 1.8 V and 3.6 V. The temperature sensor is internally
Description STM32F405xx, STM32F407xx
38/185 DocID022152 Rev 4
connected to the ADC1_IN16 input channel which is used to convert the sensor output
voltage into a digital value.
As the offset of the temperature sensor varies from chip to chip due to process variation, the
internal temperature sensor is mainly suitable for applications that detect temperature
changes instead of absolute temperatures. If an accurate temperature reading is needed,
then an external temperature sensor part should be used.
2.2.37 Digital-to-analog converter (DAC)
The two 12-bit buffered DAC channels can be used to convert two digital signals into two
analog voltage signal outputs.
This dual digital Interface supports the following features:
• two DAC converters: one for each output channel
• 8-bit or 12-bit monotonic output
• left or right data alignment in 12-bit mode
• synchronized update capability
• noise-wave generation
• triangular-wave generation
• dual DAC channel independent or simultaneous conversions
• DMA capability for each channel
• external triggers for conversion
• input voltage reference VREF+
Eight DAC trigger inputs are used in the device. The DAC channels are triggered through
the timer update outputs that are also connected to different DMA streams.
2.2.38 Serial wire JTAG debug port (SWJ-DP)
The ARM SWJ-DP interface is embedded, and is a combined JTAG and serial wire debug
port that enables either a serial wire debug or a JTAG probe to be connected to the target.
Debug is performed using 2 pins only instead of 5 required by the JTAG (JTAG pins could
be re-use as GPIO with alternate function): the JTAG TMS and TCK pins are shared with
SWDIO and SWCLK, respectively, and a specific sequence on the TMS pin is used to
switch between JTAG-DP and SW-DP.
2.2.39 Embedded Trace Macrocell™
The ARM Embedded Trace Macrocell provides a greater visibility of the instruction and data
flow inside the CPU core by streaming compressed data at a very high rate from the
STM32F40x through a small number of ETM pins to an external hardware trace port
analyser (TPA) device. The TPA is connected to a host computer using USB, Ethernet, or
any other high-speed channel. Real-time instruction and data flow activity can be recorded
and then formatted for display on the host computer that runs the debugger software. TPA
hardware is commercially available from common development tool vendors.
The Embedded Trace Macrocell operates with third party debugger software tools.

1. Function availability depends on the chosen device.
2. PC13, PC14, PC15 and PI8 are supplied through the power switch. Since the switch only sinks a limited amount of current
(3 mA), the use of GPIOs PC13 to PC15 and PI8 in output mode is limited:
- The speed should not exceed 2 MHz with a maximum load of 30 pF.
- These I/Os must not be used as a current source (e.g. to drive an LED).
3. Main function after the first backup domain power-up. Later on, it depends on the contents of the RTC registers even after
reset (because these registers are not reset by the main reset). For details on how to manage these I/Os, refer to the RTC
register description sections in the STM32F4xx reference manual, available from the STMicroelectronics website:
www.st.com.
4. FT = 5 V tolerant except when in analog mode or oscillator mode (for PC14, PC15, PH0 and PH1).
5. If the device is delivered in an UFBGA176 or WLCSP90 and the BYPASS_REG pin is set to VDD (Regulator off/internal reset
ON mode), then PA0 is used as an internal Reset (active low).

5 Electrical characteristics
5.1 Parameter conditions
Unless otherwise specified, all voltages are referenced to VSS.
5.1.1 Minimum and maximum values
Unless otherwise specified the minimum and maximum values are guaranteed in the worst
conditions of ambient temperature, supply voltage and frequencies by tests in production on
100% of the devices with an ambient temperature at TA = 25 °C and TA = TAmax (given by
the selected temperature range).
Data based on characterization results, design simulation and/or technology characteristics
are indicated in the table footnotes and are not tested in production. Based on
characterization, the minimum and maximum values refer to sample tests and represent the
mean value plus or minus three times the standard deviation (mean±3Σ).
5.1.2 Typical values
Unless otherwise specified, typical data are based on TA = 25 °C, VDD = 3.3 V (for the
1.8 V ≤ VDD ≤ 3.6 V voltage range). They are given only as design guidelines and are not
tested.
Typical ADC accuracy values are determined by characterization of a batch of samples from
a standard diffusion lot over the full temperature range, where 95% of the devices have an
error less than or equal to the value indicated (mean±2Σ).
5.1.3 Typical curves
Unless otherwise specified, all typical curves are given only as design guidelines and are
not tested.
5.1.4 Loading capacitor
The loading conditions used for pin parameter measurement are shown in Figure 19.
5.1.5 Pin input voltage
The input voltage measurement on a pin of the device is described in Figure 20.

5.1.6 Power supply scheme
Figure 21. Power supply scheme
1. Each power supply pair must be decoupled with filtering ceramic capacitors as shown above. These
capacitors must be placed as close as possible to, or below, the appropriate pins on the underside of the
PCB to ensure the good functionality of the device.
2. To connect BYPASS_REG and PDR_ON pins, refer to Section 2.2.16: Voltage regulator and Table 2.2.15:
Power supply supervisor.
3. The two 2.2 μF ceramic capacitors should be replaced by two 100 nF decoupling capacitors when the
voltage regulator is OFF.
4. The 4.7 μF ceramic capacitor must be connected to one of the VDD pin.
5. VDDA=VDD and VSSA=VSS.

3. Positive injection is not possible on these I/Os. A negative injection is induced by VINVDD while a negative injection is induced by VIN 25 MHz.
4. When the ADC is ON (ADON bit set in the ADC_CR2 register), add an additional power consumption of 1.6 mA per ADC for
the analog part.
5. When analog peripheral blocks such as ADCs, DACs, HSE, LSE, HSI, or LSI are ON, an additional power consumption
should be considered.

Figure 29. Typical VBAT current consumption (LSE and RTC ON/backup RAM ON)
I/O system current consumption
The current consumption of the I/O system has two components: static and dynamic.
I/O static current consumption
All the I/Os used as inputs with pull-up generate current consumption when the pin is
externally held low. The value of this current consumption can be simply computed by using
the pull-up/pull-down resistors values given in Table 47: I/O static characteristics.
For the output pins, any external pull-down or external load must also be considered to
estimate the current consumption.
Additional I/O current consumption is due to I/Os configured as inputs if an intermediate
voltage level is externally applied. This current consumption is caused by the input Schmitt
trigger circuits used to discriminate the input value. Unless this specific configuration is
required by the application, this supply current consumption can be avoided by configuring
these I/Os in analog mode. This is notably the case of ADC input pins which should be
configured as analog inputs.
Caution: Any floating input pin can also settle to an intermediate voltage level or switch inadvertently,
as a result of external electromagnetic noise. To avoid current consumption related to
floating pins, they must either be configured in analog mode, or forced internally to a definite
digital value. This can be done either by using pull-up/down resistors or by configuring the
pins in output mode.
I/O dynamic current consumption
In addition to the internal peripheral current consumption measured previously (see
Table 27: Peripheral current consumption), the I/Os used by an application also contribute
to the current consumption. When an I/O pin switches, it uses the current from the MCU

On-chip peripheral current consumption
The current consumption of the on-chip peripherals is given in Table 27. The MCU is placed
under the following conditions:
• At startup, all I/O pins are configured as analog pins by firmware.
• All peripherals are disabled unless otherwise mentioned
• The code is running from Flash memory and the Flash memory access time is equal to
5 wait states at 168 MHz.
• The code is running from Flash memory and the Flash memory access time is equal to
4 wait states at 144 MHz, and the power scale mode is set to 2.
• ART accelerator and Cache off.
• The given value is calculated by measuring the difference of current consumption
– with all peripherals clocked off
– with one peripheral clocked on (with only the clock applied)
• When the peripherals are enabled: HCLK is the system clock, fPCLK1 = fHCLK/4, and
fPCLK2 = fHCLK/2.
• The typical values are obtained for VDD = 3.3 V and TA= 25 °C, unless otherwise
specified.

For CL1 and CL2, it is recommended to use high-quality external ceramic capacitors in the
5 pF to 25 pF range (typ.), designed for high-frequency applications, and selected to match
the requirements of the crystal or resonator (see Figure 32). CL1 and CL2 are usually the
same size. The crystal manufacturer typically specifies a load capacitance which is the
series combination of CL1 and CL2. PCB and MCU pin capacitance must be included (10 pF
can be used as a rough estimate of the combined pin and board capacitance) when sizing
CL1 and CL2.
Note: For information on electing the crystal, refer to the application note AN2867 “Oscillator

Equation 2
Equation 2 allows to calculate the increment step (INCSTEP):
fVCO_OUT must be expressed in MHz.
With a modulation depth (md) = ±2 % (4 % peak to peak), and PLLN = 240 (in MHz):
An amplitude quantization error may be generated because the linear modulation profile is
obtained by taking the quantized values (rounded to the nearest integer) of MODPER and
INCSTEP. As a result, the achieved modulation depth is quantized. The percentage
quantized modulation depth is given by the following formula:
As a result:
Figure 35 and Figure 36 show the main PLL output clock waveforms in center spread and
down spread modes, where:
F0 is fPLL_OUT nominal.
Tmode is the modulation period.
md is the modulation depth.

While a simple application is executed on the device (toggling 2 LEDs through I/O ports).
the device is stressed by two electromagnetic events until a failure occurs. The failure is
indicated by the LEDs:
• Electrostatic discharge (ESD) (positive and negative) is applied to all device pins until
a functional disturbance occurs. This test is compliant with the IEC 61000-4-2 standard.
• FTB: A burst of fast transient voltage (positive and negative) is applied to VDD and VSS
through a 100 pF capacitor, until a functional disturbance occurs. This test is compliant
with the IEC 61000-4-4 standard.

STM32F405xx, STM32F407xx Electrical characteristics
A device reset allows normal operations to be resumed.
The test results are given in Table 42. They are based on the EMS levels and classes
defined in application note AN1709.
Designing hardened software to avoid noise problems
EMC characterization and optimization are performed at component level with a typical
application environment and simplified MCU software. It should be noted that good EMC
performance is highly dependent on the user application and the software in particular.
Therefore it is recommended that the user applies EMC software optimization and
prequalification tests in relation with the EMC level requested for his application.
Software recommendations
The software flowchart must include the management of runaway conditions such as:
• Corrupted program counter
• Unexpected reset
• Critical Data corruption (control registers...)
Prequalification trials
Most of the common failures (unexpected reset and program counter corruption) can be
reproduced by manually forcing a low state on the NRST pin or the Oscillator pins for 1
second.
To complete these trials, ESD stress can be applied directly on the device, over the range of
specification values. When unexpected behavior is detected, the software can be hardened
to prevent unrecoverable errors occurring (see application note AN1015).
Electromagnetic Interference (EMI)
The electromagnetic field emitted by the device are monitored while a simple application,
executing EEMBC? code, is running. This emission test is compliant with SAE IEC61967-2
standard which specifies the test board and the pin loading.

5.3.14 Absolute maximum ratings (electrical sensitivity)
Based on three different tests (ESD, LU) using specific measurement methods, the device is
stressed in order to determine its performance in terms of electrical sensitivity.
Electrostatic discharge (ESD)
Electrostatic discharges (a positive then a negative pulse separated by 1 second) are
applied to the pins of each sample according to each pin combination. The sample size
depends on the number of supply pins in the device (3 parts × (n+1) supply pins). This test
conforms to the JESD22-A114/C101 standard.
Static latchup
Two complementary static tests are required on six parts to assess the latchup
performance:
• A supply overvoltage is applied to each power supply pin
• A current injection is applied to each input, output and configurable I/O pin
These tests are compliant with EIA/JESD 78A IC latchup standard.

5.3.15 I/O current injection characteristics
As a general rule, current injection to the I/O pins, due to external voltage below VSS or
above VDD (for standard, 3 V-capable I/O pins) should be avoided during normal product
operation. However, in order to give an indication of the robustness of the microcontroller in
cases when abnormal injection accidentally happens, susceptibility tests are performed on a
sample basis during device characterization.
Functional susceptibilty to I/O current injection
While a simple application is executed on the device, the device is stressed by injecting
current into the I/O pins programmed in floating input mode. While current is injected into
the I/O pin, one at a time, the device is checked for functional failures.
The failure is indicated by an out of range parameter: ADC error above a certain limit (>5
LSB TUE), out of conventional limits of induced leakage current on adjacent pins (out of
5 uA/+0 uA range), or other functional failure (for example reset, oscillator frequency
deviation).
Negative induced leakage current is caused by negative injection and positive induced
leakage current by positive injection.
The test results are given in Table 46.

In the user application, the number of I/O pins which can drive current must be limited to
respect the absolute maximum rating specified in Section 5.2. In particular:
• The sum of the currents sourced by all the I/Os on VDD, plus the maximum Run
consumption of the MCU sourced on VDD, cannot exceed the absolute maximum rating
IVDD (see Table 12).
• The sum of the currents sunk by all the I/Os on VSS plus the maximum Run
consumption of the MCU sunk on VSS cannot exceed the absolute maximum rating
IVSS (see Table 12).

5.3.19 Communications interfaces
I2C interface characteristics
The STM32F405xx and STM32F407xx I2C interface meets the requirements of the
standard I2C communication protocol with the following restrictions: the I/O pins SDA and
SCL are mapped to are not “true” open-drain. When configured as open-drain, the PMOS
connected between the I/O pin and VDD is disabled, but is still present.
The I2C characteristics are described in Table 53. Refer also to Section 5.3.16: I/O port
characteristics for more details on the input/output alternate function characteristics (SDA
and SCL).

achieve fast mode I2C frequencies, and a multiple of 10 MHz to reach the 400 kHz maximum I2C fast mode
clock.
3. The device must internally provide a hold time of at least 300 ns for the SDA signal in order to bridge the
undefined region of the falling edge of SCL.
4. The maximum data hold time has only to be met if the interface does not stretch the low period of SCL

SPI interface characteristics
Unless otherwise specified, the parameters given in Table 55 for SPI are derived from tests
performed under the ambient temperature, fPCLKx frequency and VDD supply voltage
conditions summarized in Table 14 with the following configuration:
• Output speed is set to OSPEEDRy[1:0] = 10
• Capacitive load C = 30 pF
• Measurement points are done at CMOS levels: 0.5 VDD
Refer to Section 5.3.16: I/O port characteristics for more details on the input/output alternate
function characteristics (NSS, SCK, MOSI, MISO).

I2S interface characteristics
Unless otherwise specified, the parameters given in Table 56 for the i2S interface are
derived from tests performed under the ambient temperature, fPCLKx frequency and VDD
supply voltage conditions summarized in Table 14, with the following configuration:
• Output speed is set to OSPEEDRy[1:0] = 10
• Capacitive load C = 30 pF
• Measurement points are done at CMOS levels: 0.5 VDD
Refer to Section 5.3.16: I/O port characteristics for more details on the input/output alternate
function characteristics (CK, SD, WS).
Note: Refer to the I2S section of RM0090 reference manual for more details on the sampling
frequency (FS). fMCK, fCK, and DCK values reflect only the digital peripheral behavior. The
value of these parameters might be slightly impacted by the source clock accuracy. DCK
depends mainly on the value of ODD bit. The digital contribution leads to a minimum value
of I2SDIV / (2 x I2SDIV + ODD) and a maximum value of (I2SDIV + ODD) / (2 x I2SDIV +
ODD). FS maximum value is supported for each mode/condition.

Note: ADC accuracy vs. negative injection current: injecting a negative current on any analog
input pins should be avoided as this significantly reduces the accuracy of the conversion
being performed on another analog input. It is recommended to add a Schottky diode (pin to
ground) to analog pins which may potentially inject negative currents.
Any positive injection current within the limits specified for IINJ(PIN) and ΣIINJ(PIN) in
Section 5.3.16 does not affect the ADC accuracy.

General PCB design guidelines
Power supply decoupling should be performed as shown in Figure 52 or Figure 53,
depending on whether VREF+ is connected to VDDA or not. The 10 nF capacitors should be
ceramic (good quality). They should be placed them as close as possible to the chip.

1. VREF+ and VREF– inputs are both available on UFBGA176. VREF+ is also available on LQFP100, LQFP144,
and LQFP176. When VREF+ and VREF– are not available, they are internally connected to VDDA and VSSA.

Synchronous waveforms and timings
Figure 59 through Figure 62 represent synchronous waveforms and Table 80 through
Table 82 provide the corresponding timings. The results shown in these tables are obtained
with the following FSMC configuration:
• BurstAccessMode = FSMC_BurstAccessMode_Enable;
• MemoryType = FSMC_MemoryType_CRAM;
• WriteBurst = FSMC_WriteBurst_Enable;
• CLKDivision = 1; (0 is not supported, see the STM32F40xxx/41xxx reference manual)
• DataLatency = 1 for NOR Flash; DataLatency = 0 for PSRAM
In all timing tables, the THCLK is the HCLK clock period (with maximum
FSMC_CLK = 60 MHz).
