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.

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:

Figure 4. Block diagram of the proposed conversion scheme
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.

AN2794 Design considerations
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:
Equation 33
The primary inductance value is:
Equation 34
and the number of secondary turns is:
Equation 35
At this point wires must be selected in order to implement primary and secondary windings.

Checking the wire table we notice that AWG26, having a wire area of AWAWG26 = 0.00128
cm2, can be used in this design. Considering a current density J = 500 A/cm2 the number of
primary wires is given by:
Equation 39
where:

Since the AWG26 has a resistance of 1345 μΩ/cm, the primary resistance is:

The peak current value across the inductor is:

μ toroid, with μ=60 permeability and AL = 0.086 nH/turn can be selected. The required
number of turns is then:
Equation 54
The resulting magnetizing force (DC bias) is:
Equation 55
The initial value of turns has to be increased by dividing it by 0.8 (as shown in the data
catalog) to take into account the reduction of initial permeability (μe = 39 at full load) at
nominal current value. Then, the adjusted number of turns is:
Equation 56
The wire table shows that at 3 A the AWG20 can be used. With this choice, the maximum
number of turns per layer, for the selected core, is Nlayer= 96 and the resistance per single

choose the power devices both for the input and output stage of the push-pull converter.

Note: Assuming: tB= trr/2, VRM= 350 V
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
1.8% efficiency improvement.

2.1 Layout considerations
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.

AN2794 Schematic description
Doc ID 14827 Rev 2 23/39
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.

The PWM modulation of the H-bridge inverter is implemented on an ST7lite39
microcontroller connected to the gate drive circuit composed of two L6386, as shown in the
schematic in Figure 11.
The auxiliary power supply section consists of an L5973D and an L7805, used to implement
a buck-boost converter to decrease the battery voltage from 24 V to 15 V and from 15 V to
5 V respectively.

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
output connectors, with 3 mH output inductor.

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.

Datasheet − production data
Features
■ Seven Darlingtons per package
■ Output current 500 mA per driver (600 mA
peak)
■ Output voltage 50 V
■ Integrated suppression diodes for inductive
loads
■ Outputs can be paralleled for higher current

Description
The ULN2001, ULN2002, ULN2003 and ULN
2004 are high voltage, high current Darlington
arrays each containing seven open collector
Darlington pairs with common emitters. Each
channel rated at 500 mA and can withstand peak
currents of 600 mA. Suppression diodes are
included for inductive load driving and the inputs
are pinned opposite the outputs to simplify board
layout.
The versions interface to all common logic
families:
– ULN2001 (general purpose, DTL, TTL,
PMOS, CMOS)
– ULN2002 (14 - 25 V PMOS)
– ULN2003 (5 V TTL, CMOS)
– ULN2004 (6 - 15 V CMOS, PMOS)
These versatile devices are useful for driving a
wide range of loads including solenoids, relays
DC motors, LED displays filament lamps, thermal
printheads and high power buffers.
The ULN2001A/2002A/2003A and 2004A are
supplied in 16 pin plastic DIP packages with a
copper leadframe to reduce thermal resistance.
They are available also in small outline package
(SO-16) as ULN2001D1/2002D1/2003D1/
2004D1

Application hints LM350
8/14
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
Figure 4. Circuit
LM350 Application hints

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.

Vin Input voltage -0.3 to 32 V
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.

Application information LM217, LM317

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

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.

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

• 4 Kbytes of backup SRAM.
The content of this area is protected against possible unwanted write accesses, and is

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.

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.

3.16.3 Regulator ON/OFF and internal reset ON/OFF availability
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.

STM32F20xxx Functional overview

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 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.

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)

• 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)
• For OTG/Host modes, a power switch is needed in case bus-powered devices are
connected

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
• 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

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).
Output voltage levels

1. 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).

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.

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.
• Up to three I2Cs
• Three SPIs, two I2Ss full duplex. To achieve audio class accuracy, the I2S peripherals
can be clocked via a dedicated internal audio PLL or via an external clock to allow
synchronization.
• Four USARTs plus two UARTs
• An USB OTG full-speed and a USB OTG high-speed with full-speed capability (with the
ULPI),
• Two CANs
• An SDIO/MMC interface
• Ethernet and the camera interface available on STM32F407xx devices only.
New advanced peripherals include an SDIO, an enhanced flexible static memory control
(FSMC) interface (for devices offered in packages of 100 pins and more), a camera
interface for CMOS sensors. Refer to Table 2: STM32F405xx and STM32F407xx: features
and peripheral counts for the list of peripherals available on each part number.
The STM32F405xx and STM32F407xx family operates in the –40 to +105 °C temperature
range from a 1.8 to 3.6 V power supply. 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: refer to Section : Internal reset OFF. A comprehensive set of power-saving
mode allows the design of low-power applications.
The STM32F405xx and STM32F407xx family offers devices in various packages ranging
from 64 pins to 176 pins. The set of included peripherals changes with the device chosen.
These features make the STM32F405xx and STM32F407xx 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

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
DocID022152 Rev 4 23/185
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

STM32F405xx, STM32F407xx Description
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.

STM32F405xx, STM32F407xx Description
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.
DocID022152 Rev 4 33/185
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)

• 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
(PTP V2) with the time stamp comparator connected to the TIM2 input
• Triggers interrupt when system time becomes greater than target time
Description STM32F405xx, STM32F407xx
36/185 DocID022152 Rev 4
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
DocID022152 Rev 4 37/185
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.

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.

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.

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.

STM32F405xx, STM32F407xx Electrical characteristics
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).

Unless otherwise specified, the parameters given in Table 48 are derived from tests

1. 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

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

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.

loads directly without the use of an external operational amplifier. The buffer can be bypassed by
configuring the BOFFx bit in the DAC_CR register.
5.3.25 FSMC characteristics
Unless otherwise specified, the parameters given in Table 75 to Table 86 for the FSMC
interface are derived from tests performed under the ambient temperature, fHCLK 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: 0.5VDD

PC Card/CompactFlash controller waveforms and timings
Figure 63 through Figure 68 represent synchronous waveforms, and Table 83 and Table 84
provide the corresponding timings. The results shown in this table are obtained with the
following FSMC configuration:
• COM.FSMC_SetupTime = 0x04;
• COM.FSMC_WaitSetupTime = 0x07;
• COM.FSMC_HoldSetupTime = 0x04;
• COM.FSMC_HiZSetupTime = 0x00;
• ATT.FSMC_SetupTime = 0x04;
• ATT.FSMC_WaitSetupTime = 0x07;
• ATT.FSMC_HoldSetupTime = 0x04;
• ATT.FSMC_HiZSetupTime = 0x00;
• IO.FSMC_SetupTime = 0x04;
• IO.FSMC_WaitSetupTime = 0x07;
• IO.FSMC_HoldSetupTime = 0x04;
• IO.FSMC_HiZSetupTime = 0x00;
• TCLRSetupTime = 0;
• TARSetupTime = 0.
In all timing tables, the THCLK is the HCLK clock period.
