Sefram-SP270.pdf-PDF..> 29-Mar-2014 11:46 464K1. General description The LPC3220/30/40/50 embedded microcontrollers were designed for low power, high performance applications. NXP achieved their performance goals using a 90 nanometer process to implement an ARM926EJ-S CPU core with a vector floating point co-processor and a large set of standard peripherals including USB On-The-Go. The LPC3220/30/40/50 operates at CPU frequencies of up to 266 MHz. The NXP implementation uses a ARM926EJ-S CPU core with a Harvard architecture, 5-stage pipeline, and an integral Memory Management Unit (MMU). The MMU provides the virtual memory capabilities needed to support the multi-programming demands of modern operating systems. The ARM926EJ-S also has a hardware based set of DSP instruction extensions, which includes single cycle MAC operations, and hardware based native Jazelle Java Byte-code execution. The NXP implementation has a 32 kB instruction cache and a 32 kB data cache. For low power consumption, the LPC3220/30/40/50 takes advantage of NXP’s advanced technology development to optimize intrinsic power and uses software controlled architectural enhancements to optimize application based power management. The LPC3220/30/40/50 also includes 256 kB of on-chip static RAM, a NAND flash interface, an Ethernet MAC, an LCD controller that supports STN and TFT panels, and an external bus interface that supports SDR and DDR SDRAM as well as static devices. In addition, the LPC3220/30/40/50 includes a USB 2.0 full-speed interface, seven UARTs, two I2C-bus interfaces, two SPI/SSP ports, two I2S-bus interfaces, two single output PWMs, a motor control PWM, six general purpose timers with capture inputs and compare outputs, a Secure Digital (SD) interface, and a 10-bit Analog-to-Digital Converter (ADC) with a touch screen sense option. 2. Features and benefits ARM926EJ-S processor, running at CPU clock speeds up to 266 MHz. Vector Floating Point (VFP) coprocessor. 32 kB instruction cache and 32 kB data cache. Up to 256 kB of Internal SRAM (IRAM). Selectable boot-up from various external devices: NAND flash, SPI memory, USB, UART, or static memory. Multi-layer AHB system that provides a separate bus for each AHB master, including both an instruction and data bus for the CPU, two data busses for the DMA controller, and another bus for the USB controller, one for the LCD, and a final one for the Ethernet MAC. There are no arbitration delays in the system unless two masters attempt to access the same slave at the same time.

Product data sheet Rev. 2 — 20 October 2011 2 of 79 NXP Semiconductors LPC3220/30/40/50 16/32-bit ARM microcontrollers External memory controller for DDR and SDR SDRAM as well as for static devices. Two NAND flash controllers: One for single-level NAND flash devices and the other for multi-level NAND flash devices. Master Interrupt Controller (MIC) and two Slave Interrupt Controllers (SIC), supporting 74 interrupt sources. Eight channel General Purpose DMA (GPDMA) controller on the AHB that can be used with the SD card port, the high-speed UARTs, I2S-bus interfaces, and SPI interfaces, as well as memory-to-memory transfers. Serial interfaces: 10/100 Ethernet MAC with dedicated DMA Controller. USB interface supporting either device, host (OHCI compliant), or On-The-Go (OTG) with an integral DMA controller and dedicated PLL to generate the required 48 MHz USB clock. Four standard UARTs with fractional baud rate generation and 64 byte FIFOs. One of the standard UARTs supports IrDA. Three additional high-speed UARTs intended for on-board communications that support baud rates up to 921 600 when using a 13 MHz main oscillator. All high-speed UARTs provide 64 byte FIFOs. Two SPI controllers. Two SSP controllers. Two I2C-bus interfaces with standard open-drain pins. The I2C-bus interfaces support single master, slave, and multi-master I2C-bus configurations. Two I2S-bus interfaces, each with separate input and output channels. Each channel can be operated independently on three pins, or both input and output channels can be used with only four pins and a shared clock. Additional peripherals: LCD controller supporting both STN and TFT panels, with dedicated DMA controller. Programmable display resolution up to 1024 768. Secure Digital (SD) memory card interface, which conforms to the SD Memory Card Specification Version 1.01. General Purpose (GP) input, output, and I/O pins. Includes 12 GP input pins, 24 GP output pins, and 51 GP I/O pins. 10-bit, 400 kHz Analog-to-Digital Converter (ADC) with input multiplexing from three pins. Optionally, the ADC can operate as a touch screen controller. Real-Time Clock (RTC) with separate power pin and dedicated 32 kHz oscillator. NXP implemented the RTC in an independent on-chip power domain so it can remain active while the rest of the chip is not powered. The RTC also includes a 32-byte scratch pad memory. 32-bit general purpose high-speed timer with a 16-bit pre-scaler. This timer includes one external capture input pin and a capture connection to the RTC clock. Interrupts may be generated using three match registers. Six enhanced timer/counters which are architecturally identical except for the peripheral base address. Two capture inputs and two match outputs are pinned out to four timers. Timer 1 brings out a third match output, timers 2 and 3 bring out all four match outputs, timer 4 has one match output, and timer 5 has no inputs or outputs. 32-bit millisecond timer driven from the RTC clock. This timer can generate interrupts using two match registers. LPC3220_30_40_50 All information provided in this document is subject to legal disclaimers. © NXP B.V. 2011. All rights reserved.

There are two special cases for determining supply domain voltages (for details see application note AN10777): a) Ethernet configured in MII mode: VDD_IOD must be the same as VDD_IOB. b) UART 3 when used with hardware flow control or when sharing an RS-232 transceiver with another UART: VDD_IOA must be the same as VDD_IOD.

Product data sheet Rev. 2 — 20 October 2011 24 of 79 NXP Semiconductors LPC3220/30/40/50 16/32-bit ARM microcontrollers 7. Functional description 7.1 CPU and subsystems 7.1.1 CPU NXP created the LPC3220/30/40/50 using an ARM926EJ-S CPU core that includes a Harvard architecture and a 5-stage pipeline. To this ARM core, NXP implemented a 32 kB instruction cache, a 32 kB data cache and a Vector Floating Point coprocessor. The ARM926EJ-S core also has an integral Memory Management Unit (MMU) to provide the virtual memory capabilities required to support the multi-programming demands of modern operating systems. The basic ARM926EJ-S core V5TE instruction set includes DSP instruction extensions for native Jazelle Java Byte-code execution in hardware. The LPC3220/30/40/50 operates at CPU frequencies up to 266 MHz. 7.1.2 Vector Floating Point (VFP) coprocessor The LPC3220/30/40/50 includes a VFP co-processor providing full support for single-precision and double-precision add, subtract, multiply, divide, and multiply-accumulate operations at CPU clock speeds. It is compliant with the IEEE 754 standard for binary Floating-Point Arithmetic. This hardware floating point capability makes the microcontroller suitable for advanced motor control and DSP applications. The VFP has 3 separate pipelines for floating-point MAC operations, divide or square root operations, and Load/Store operations. These pipelines operate in parallel and can complete execution out of order. All single-precision instructions execute in one cycle, except the divide and square root instructions. All double-precision multiply and multiply-accumulate instructions take two cycles. The VFP also provides format conversions between floating-point and integer word formats. 7.1.3 Emulation and debugging The LPC3220/30/40/50 supports emulation and debugging via a dedicated JTAG serial port. An Embedded Trace Buffer allows tracing program execution. The dedicated JTAG port allows debugging of all chip features without impact to any pins that may be used in the application. 7.1.3.1 Embedded ICE Standard ARM EmbeddedICE logic provides on-chip debug support. The debugging of the target system requires a host computer running the debugger software and an Embedded ICE protocol converter. The Embedded ICE protocol converter converts the Remote Debug Protocol commands to the JTAG data needed to access the ARM core. The ARM core has a Debug Communication Channel (DCC) function built-in. The debug communication channel allows a program running on the target to communicate with the host debugger or another separate host without stopping the program flow or entering the debug state.

Product data sheet Rev. 2 — 20 October 2011 25 of 79 NXP Semiconductors LPC3220/30/40/50 16/32-bit ARM microcontrollers 7.1.3.2 Embedded trace buffer The Embedded Trace Module (ETM) is connected directly to the ARM core. It compresses the trace information and exports it through a narrow trace port. An internal Embedded Trace Buffer (ETB) of 2048 24 bits captures the trace information under software debugger control. Data from the ETB is recovered by the debug software through the JTAG port. The trace contains information about when the ARM core switches between states. Instruction shows the flow of execution of the processor and provides a list of all the instructions that were executed. Instruction trace is significantly compressed by only broadcasting branch addresses as well as a set of status signals that indicate the pipeline status on a cycle by cycle basis. For data accesses either data or address or both can be traced. 7.2 AHB matrix The LPC3220/30/40/50 has a multi-layer AHB matrix for inter-block communication. AHB is an ARM defined high-speed bus, which is part of the ARM bus architecture. AHB is a high-bandwidth low-latency bus that supports multi-master arbitration and a bus grant/request mechanism. For systems that have only one (CPU), or two (CPU and DMA) bus masters a simple AHB works well. However, if a system requires multiple bus masters and the CPU needs access to external memory, a single AHB bus can cause a bottleneck. To increase performance, the LPC3220/30/40/50 uses an expanded AHB architecture known as Multi-layer AHB. A Multi-layer AHB replaces the request/grant and arbitration mechanism used in a simple AHB with an interconnect matrix that moves arbitration out toward the slave devices. Thus, if a CPU and a DMA controller want access to the same memory, the interconnect matrix arbitrates between the two when granting access to the memory. This advanced architecture allows simultaneous access by bus masters to different resources with an increase in arbitration complexity. In this architectural implementation, removing guaranteed central arbitration and allowing more than one bus master to be active at the same time provides better overall microcontroller performance. In the LPC3220/30/40/50, the multi-Layer AHB system has a separate bus for each of seven AHB Masters: • CPU data bus • CPU instruction bus • General purpose DMA Master 0 • General purpose DMA Master 1 • Ethernet controller • USB controller • LCD controller There are no arbitration delays unless two masters attempt to access the same slave at the same time.

Product data sheet Rev. 2 — 20 October 2011 26 of 79 NXP Semiconductors LPC3220/30/40/50 16/32-bit ARM microcontrollers 7.2.1 APB Many peripheral functions are accessed by on-chip APBs that are attached to the higher speed AHB. The APB performs reads and writes to peripheral registers in three peripheral clocks. 7.2.2 FAB Some peripherals are placed on a special bus called FAB that allows faster CPU access to those peripheral functions. A write access to FAB peripherals takes a single AHB clock and a read access to FAB peripherals takes two AHB clocks. 7.3 Physical memory map The physical memory map incorporates several distinct regions, as shown in Figure 3. When an application is running, the CPU interrupt vectors are re-mapped to allow them to reside in on-chip SRAM (IRAM).

Product data sheet Rev. 2 — 20 October 2011 28 of 79 NXP Semiconductors LPC3220/30/40/50 16/32-bit ARM microcontrollers 7.4 Internal memory 7.4.1 On-chip ROM The built-in 16 kB ROM contains a program which runs a boot procedure to load code from one of four external sources, UART 5, SSP0 (SPI mode), EMC Static CS0 memory, or NAND FLASH. After reset, execution always begins from the internal ROM. The bootstrap software first reads the SERVICE input (GPI_1). If SERVICE is LOW, the bootstrap starts a service boot and can download a program over serial link UART 5 to IRAM and transfer execution to the downloaded code. If the SERVICE pin is HIGH, the bootstrap routine jumps to normal boot. The normal boot process first tests SPI memory for boot information if present it uploads the boot code and transfers execution to the uploaded software. If the SPI is not present or no software is loaded, the bootloader will test the EMC Static CS0 memory for the presence of boot code and if present boots from static memory, If this test fails the boot loader will test external NAND flash for boot code and boot if code is present. The boot loader consumes no user memory space because it is in ROM. 7.4.2 On-chip SRAM On-chip SRAM may be used for code and/or data storage. The SRAM may be accessed as 8, 16, or 32 bit memory. The LPC3220/30/40/50 provides 256 kB of internal SRAM. 7.5 External memory interfaces The LPC3220/30/40/50 includes three external memory interfaces, NAND Flash controllers, Secure Digital Memory Controller, and an external memory controller for SDRAM, DDR SDRAM, and Static Memory devices. 7.5.1 NAND flash controllers The LPC3220/30/40/50 includes two NAND flash controllers, one for multi-level cell NAND flash devices and one for single-level cell NAND flash devices. The two NAND flash controllers use the same pins to interface to external NAND flash devices, so only one interface is active at a time. 7.5.1.1 Multi-Level Cell (MLC) NAND flash controller The MLC NAND flash controller interfaces to either multi-level or single-level NAND flash devices. An external NAND flash device is used to allow the bootloader to automatically load a portion of the application code into internal SRAM for execution following reset. The MLC NAND flash controller supports small (528 byte) and large (2114 byte) pages. Programmable NAND timing parameters allow support for a variety of NAND flash devices. A built-in Reed-Solomon encoder/decoder provides error detection and correction capability. A 528 byte data buffer reduces the need for CPU supervision during loading. The MLC NAND flash controller also provides DMA support. LPC3220_30_40_50 All information provided in this document is subject to legal disclaimers. © NXP B.V. 2011. All rights reserved.

Each of these four peripherals contain an integral DMA controller optimized to support the performance demands of the peripheral. 7.6.1 General Purpose DMA (GPDMA) controller The GPDMA controller allows peripheral-to memory, memory-to-peripheral, peripheral-to-peripheral, and memory-to-memory transactions. Each DMA stream provides unidirectional serial DMA transfers for a single source and destination. For example, a bidirectional port requires one stream for transmit and one for receive. The source and destination areas can each be either a memory region or a peripheral, and can be accessed through the same AHB master, or one area by each master. The DMA controller supports the following peripheral device transfers. • Secure Digital (SD) Memory interface • High-speed UARTs • I2S0 and I2S1 ports • SPI1 and SPI2 interfaces • SSP0 and SSP1 interfaces • Memory The DMA controls eight DMA channels with hardware prioritization. The DMA controller interfaces to the system via two AHB bus masters, each with a full 32-bit data bus width. DMA operations may be set up for 8-bit, 16-bit, and 32-bit data widths, and can be either big-endian or little-endian. Incrementing or non-incrementing addressing for source and destination are supported, as well as programmable DMA burst size. Scatter or gather DMA is supported through the use of linked lists. This means that the source and destination areas do not have to occupy contiguous areas of memory. 7.6.2 Ethernet MAC The Ethernet block contains a full featured 10 Mbit/s or 100 Mbit/s Ethernet MAC designed to provide optimized performance through the use of DMA hardware acceleration. Features include a generous suite of control registers, half or full duplex operation, flow control, control frames, hardware acceleration for transmit retry, receive LPC3220_30_40_50 All information provided in this document is subject to legal disclaimers. © NXP B.V. 2011.

Product data sheet Rev. 2 — 20 October 2011 34 of 79 NXP Semiconductors LPC3220/30/40/50 16/32-bit ARM microcontrollers 7.7 System functions To enhance the performance of the LPC3220/30/40/50 incorporates the following system functions, an Interrupt Controller (INTC), a watchdog timer, a millisecond timer, and several power control features. These functions are described in the following sections 7.7.1 Interrupt controller The interrupt controller is comprised of three basic interrupt controller blocks, supporting a total of 73 interrupt sources. Each interrupt source can be individually enabled/disabled and configured for high or low level triggering, or rising or falling edge triggering. Each interrupt may also be steered to either the FIQ or IRQ input of the ARM9. Raw interrupt status and masked interrupt status registers allow versatile condition evaluation. In addition to peripheral functions, each of the six general purpose input/output pins and 12 of the 22 general purpose input pins are connected directly to the interrupt controller. 7.7.2 Watchdog timer The watchdog timer block is clocked by the main peripheral clock, which clocks a 32-bit counter. A match register is compared to the Timer. When configured for watchdog functionality, a match drives the match output low. The match output is gated with an enable signal that gives the opportunity to generate two type of reset signal: one that only resets chip internally, and another that goes through a programmable pulse generator before it goes to the external pin RESOUT and to the internal chip reset. 7.7.2.1 Features • Programmable 32-bit timer. • Internally resets the device if not periodically reloaded. • Flag to indicate that a watchdog reset has occurred. • Programmable watchdog pulse output on RESOUT pin. • Can be used as a standard timer if watchdog is not used. • Pause control to stop counting when core is in debug state. 7.7.3 Millisecond timer The millisecond timer is clocked by 32 kHz RTC clock, so a prescaler is not needed to obtain a lower count rate. The millisecond timer includes three match registers that are compared to the Timer/Counter value. A match can generate an interrupt and the cause the Timer/Counter either continue to run, stop, or be reset. 7.7.3.1 Features • 32-bit Timer/Counter, running from the 32 kHz RTC clock. • Counter or Timer operation. • Three 32-bit match registers that allow: – Continuous operation with optional interrupt generation on match. – Stop timer on match with optional interrupt generation. – Reset timer on match with optional interrupt generation. • Pause control to stop counting when core is in debug state.

Product data sheet Rev. 2 — 20 October 2011 35 of 79 NXP Semiconductors LPC3220/30/40/50 16/32-bit ARM microcontrollers 7.7.4 Clocking and power control features 7.7.4.1 Clocking Clocking in the LPC3220/30/40/50 is designed to be versatile, so that system and peripheral requirements may be met, while allowing optimization of power consumption. Clocks to most functions may be turned off if not needed and some peripherals do this automatically. The LPC3220/30/40/50 supports three operational modes, two of which are specifically designed to reduce power consumption. The modes are: Run mode, Direct run mode, and Stop mode.These three operational modes give control over processing speed and power consumption. In addition, clock rates to different functional blocks may be changed by switching clock sources, changing PLL values, or altering clock divider configurations. This allows a trade-off of power versus processing speed based on application requirements. 7.7.4.2 Crystal oscillator The main oscillator is the basis for the clocks most chip functions use by default. Optionally, many functions can be clocked instead by the output of a PLL (with a fixed 397x rate multiplication) which runs from the RTC oscillator. In this mode, the main oscillator may be turned off unless the USB interface is enabled. If a SYSCLK frequency other than 13 MHz is required in the application, or if the USB block is not used, the main oscillator may be used with a frequency of between 1 MHz and 20 MHz. 7.7.4.3 PLLs The LPC3220/30/40/50 includes three PLLs: The 397x PLL allows boosting the RTC frequency to 13.008896 MHz for use as the primary system clock. The USB PLL provides the 48 MHz clock required by the USB block, and the HCLK PLL provides the basis for the CPU clock, the AHB bus clock, and the main peripheral clock. The 397x PLL multiplies the 32768 Hz RTC clock by 397 to obtain a 13.008896 MHz clock. The 397x PLL is designed for low power operation and low jitter. This PLL requires an external RC loop filter for proper operation. The HCLK PLL accepts an input clock from either the main oscillator or the output of the 397x PLL. The USB PLL only accepts an input clock from the main oscillator.The USB input clock runs through a divide-by-N pre-divider before entering the USB PLL. The input to the HCLK and USB PLLs may initially be divided down by a pre-divider value ‘N’, which may have the values 1, 2, 3, or 4. This pre-divider can allow a greater number of possibilities for the output frequency. Following the PLL input divider is the PLL multiplier. This can multiply the pre-divider output by a value ‘M’, in the range of 1 through 256. The resulting frequency must be in the range of 156 MHz to 320 MHz. The multiplier works by dividing the output of a Current Controlled Oscillator (CCO) by the value of M, then using a phase detector to compare the divided CCO output to the pre-divider output. The error value is used to adjust the CCO frequency. At the PLL output, there is a post-divider that can be used to bring the CCO frequency down to the desired PLL output frequency. The post-divider value can divide the CCO output by 1, 2, 4, 8, or 16. The post-divider can also be bypassed, allowing the PLL CCO LPC3220_30_40_50 All information provided in this document is subject to legal disclaimers. © NXP B.V. 2011. All rights reserved. Product data sheet Rev. 2 — 20 October 2011 36 of 79 NXP Semiconductors LPC3220/30/40/50 16/32-bit ARM microcontrollers output to be used directly. The maximum PLL output frequency supported by the CPU is 266 MHz. The only output frequency supported by the USB PLL is 48 MHz, and the clock has strict requirements for nominal frequency (500 ppm) and jitter (500 ps). 7.7.4.4 Power control modes The LPC3220/30/40/50 supports three operational modes, two of which are specifically designed to reduce power consumption. The modes are: Run mode, Direct Run mode, and Stop mode. Run mode is the normal operating mode for applications that require the CPU, AHB bus, or any peripheral function other than the USB block to run faster than the main oscillator frequency. In Run mode, the CPU can run at up to 266 MHz and the AHB bus can run at up to 133 MHz. Direct Run mode allows reducing the CPU and AHB bus rates in order to save power. Direct Run mode can also be the normal operating mode for applications that do not require the CPU, AHB bus, or any peripheral function other than the USB block to run faster than the main oscillator frequency. Direct Run mode is the default mode following chip reset. Stop mode causes all CPU and AHB operation to cease, and stops clocks to peripherals other than the USB block. 7.7.4.5 Reset Reset is accomplished by an active LOW signal on the RESET input pin. A reset pulse with a minimum width of 10 main oscillator clocks after the oscillator is stable is required to guarantee a valid chip reset. At power-up, 10 milliseconds should be allowed for the oscillator to start up and stabilize after VDD reaches operational voltage. An internal reset with a minimum duration of 10 clock pulses will also be applied if the watchdog timer generates an internal device reset. The RESET pin is located in the RTC power domain. This means that the RTC power must be present for an external reset to have any effect. The RTC power domain nominally runs from 1.2 V, but the RESET pin can be driven as high as 1.95 V. 7.8 Communication peripheral interfaces In addition to the Ethernet MAC and USB interfaces there are many more serial communication peripheral interfaces available on the LPC3220/30/40/50. Here is a list of the serial communication interfaces: • Seven UARTs; four standard UARTs and three high-speed UARTs • Two SPI serial I/O controllers • Two SSP serial I/O controllers • Two I2C serial I/O controllers • Two I2S audio controllers A short functional description of each of these peripherals is provided in the following sections.

The SPI implementation on the LPC3220/30/40/50 does not support operation as a slave. 7.8.2.1 Features • Supports slaves compatible with SPI modes 0 to 3. • Half duplex synchronous transfers. • DMA support for data transmit and receive. • 1-bit to 16-bit word length. • Choice of LSB or MSB first data transmission. • 64 16-bit input or output FIFO. • Bit rates up to 52 Mbit/s. • Busy input function. • DMA time out interrupt to allow detection of end of reception when using DMA. • Timed interrupt to facilitate emptying the FIFO at the end of a transmission. • SPI clock and data pins may be used as general purpose pins if the SPI is not used. • Slave selects can be supported using GPO or GPIO pins 7.8.3 SSP serial I/O controller The LPC3220/30/40/50 contains two SSP controllers. The SSP controller is capable of operation on a SPI, 4-wire SSI, or Microwire bus. It can interact with multiple masters and slaves on the bus. Only a single master and a single slave can communicate on the bus during a given data transfer. The SSP supports full duplex transfers, with frames of 4 bits to 16 bits of data flowing from the master to the slave and from the slave to the master. In practice, often only one of these data flows carries meaningful data. 7.8.3.1 Features • Compatible with Motorola SPI, 4-wire TI SSI, and National Semiconductor Microwire buses • Synchronous serial communication • Master or slave operation • 8-frame FIFOs for both transmit and receive • 4-bit to 16-bit frame • Maximum SPI bus data bit rate of 1⁄2 (Master mode) and 1⁄2 (Slave mode) of the input clock rate • DMA transfers supported by GPDMA 7.8.4 I2C-bus serial I/O controller There are two I2C-bus interfaces in the LPC32x0 family of controllers. These I2C blocks can be configured as a master, multi-master or slave supporting up to 400 kHz. The I2C blocks also support 7 or 10 bit addressing. Each has a four word FIFO for both transmit and receive. An interrupt signal is available from each block.

Product data sheet Rev. 2 — 20 October 2011 39 of 79 NXP Semiconductors LPC3220/30/40/50 16/32-bit ARM microcontrollers There is a separate slave transmit FIFO. The slave transmit FIFO (TXS) and its level are only available when the controller is configured as a Master/Slave device and is operating in a multi-master environment. Separate TX FIFOs are needed in a multi-master because a controller might have a message queued for transmission when an external master addresses it to be come a slave-transmitter, a second source of data is needed. Note that the I2C clock must be enabled in the I2CCLK_CTRL register before using the I2C. The I2C clock can be disabled between communications, if used as a single master I2C-bus interface, software has full control of when I2C communication is taking place on the bus. 7.8.4.1 Features • The two I2C-bus blocks are standard I2C-bus compliant interfaces that may be used in Single-master, Multi-master or Slave modes. • Programmable clock to allow adjustment of I2C-bus transfer rates. • Bidirectional data transfer. • Serial clock synchronization allows devices with different bit rates to communicate via one serial bus. • Serial clock synchronization can be used as a handshake mechanism to suspend and resume serial transfer. 7.8.5 I2S-bus audio controller The I2S-bus provides a standard communication interface for digital audio applications The I2S-bus specification defines a 3-wire serial bus using one data line, one clock line, and one word select signal. Each I2S connection can act as a master or a slave. The master connection determines the frequency of the clock line and all other slaves are driven by this clock source. The two I2S-bus interfaces on the LPC3220/30/40/50 provides a separate transmit and receive channel, providing a total of two transmit channels and two receive channels. Each I2S channel supports monaural or stereo formatted data. 7.8.5.1 Features • The interface has separate input/output channels each of which can operate in master or slave mode. • Capable of handling 8-bit, 16-bit, and 32-bit word sizes. • Mono and stereo audio data supported. • Supports standard sampling frequencies (8 kHz, 11.025 kHz, 16 kHz, 22.05 kHz, 32 kHz, 44.1 kHz, 48 kHz, 96 kHz). • Word select period can be configured in master mode (separately for I2S input and output). • Two eight-word FIFO data buffers are provided, one for transmit and one for receive. • Generates interrupt requests when buffer levels cross a programmable boundary. • Two DMA requests, controlled by programmable buffer levels. These are connected to the GPDMA block. • Controls include reset, stop, and mute options separately for I2S input and I2S output.

Here is a list of the general purpose peripherals. • GPI/O • Keyboard scanner • Touch screen controller and 10-bit Analog-to-Digital-Converter • Real-time clock • High-speed timer • Four general purpose 32-bit timer/external event counters • Two simple PWMs • One motor control PWM A short functional description of each of these peripherals is provided in the following sections. 7.9.1 General purpose parallel I/O Some device pins that are not dedicated to a specific peripheral function have been designed to be general purpose inputs, outputs, or input/outputs. Also, some pins may be configured either as a specific peripheral function or a general purpose input, output, or input/output. A total of 51 pins can potentially be used as general purpose input/outputs, 24 as general purpose outputs, and 22 as general purpose inputs. GPIO pins may be dynamically configured as inputs or outputs. Separate registers allow setting or clearing any number of GPIO and GPO outputs controlled by that register simultaneously. The value of the output register for standard GPIOs and GPO pins may be read back, as well as the current actual state of the port pins. In addition to GPIO pins on port 0, port 1, and port 2, there are 22 GPI, 24 GPO, and six GPIO pins. When the SDRAM bus is configured for 16 data bits, 13 of the remaining SDRAM data pins may be used as GPIOs. 7.9.1.1 Features • Bit-level set and clear registers allow a single instruction set or clear of any number of bits in one port. • A single register selects direction for pins that support both input and output modes. • Direction control of individual bits. • For input/output pins, both the programmed output state and the actual pin state can be read. • There are a total of 12 general purpose inputs, 24 general purpose outputs, and six general purpose input/outputs. • Additionally, 13 SDRAM data lines may be used as GPIOs if a 16-bit SDRAM interface is used (rather than a 32-bit interface).

Product data sheet Rev. 2 — 20 October 2011 41 of 79 NXP Semiconductors LPC3220/30/40/50 16/32-bit ARM microcontrollers 7.9.2 Keyboard scanner The keyboard scanner function can automatically scan a keyboard of up to 64 keys in an 8 8 matrix. In operation, the keyboard scanner’s internal state machine will normally be in an idle state, with all KEY_ROWn pins set high, waiting for a change in the column inputs to indicate that one or more keys have been pressed. When a keypress is detected, the matrix is scanned by setting one output pin high at a time and reading the column inputs. After de-bouncing, the keypad state is stored and an interrupt is generated. The keypad is then continuously scanned waiting for ‘extra key pressed’ or ‘key released’. Any new keypad state is scanned and stored into the matrix registers followed by a new interrupt request to the interrupt controller. It is possible to detect and separate up to 64 multiple keys pressed. 7.9.2.1 Features • Supports up to 64 keys in 8 8 matrix. • Programmable de-bounce period. • A key press can wake up the CPU from Stop mode. 7.9.3 Touch screen controller and 10-bit ADC The LPC3220/30/40/50 microcontrollers includes Touch Screen Controller (TSC) hardware, which automatically measures and determines the X and Y coordinates where a touch screen is pressed. In addition, the TSC can measure an analog input signal on the AUX_IN pin. Optionally, the TSC can operate as an Analog-to-Digital Converter (ADC). The ADC supports three channels and uses 10-bit successive approximation to produce results with a resolution of 10 bits in 11 clock cycles. The analog portion of the ADC has its own power supply to enhance the low noise characteristics of the converter. This voltage is only supplied internally when the core has voltage. However, the ADC block is not affected by any difference in ramp-up time for VDD_AD and VDD_CORE voltage supplies. 7.9.3.1 Features • Measurement range of 0 V to VDD_AD (nominally 3.3 V). • Low-noise ADC. • 10-bit resolution. • Three input channels. • Uses 32 kHz RTC clock or peripheral clock. 7.9.4 Real-Time Clock (RTC) and battery RAM The RTC runs at 32768 Hz using a very low power oscillator. The RTC counts seconds and can generate alarm interrupts that can wake up the device from Stop mode. The RTC clock can also clock the 397x PLL, the Millisecond Timer, the ADC, the Keyboard Scanner and the PWMs. The RTC up-counter value represents a number of seconds elapsed since second 0, which is an application determined time. The RTC counter will reach maximum value after about 136 years. The RTC down-counter is initiated with all ones.

Product data sheet Rev. 2 — 20 October 2011 42 of 79 NXP Semiconductors LPC3220/30/40/50 16/32-bit ARM microcontrollers Two 32-bit match registers are readable and writable by the processor. A match will result in an interrupt provided that the interrupt is enabled. The ONSW output pin can also be triggered by a match event and cause an external power supply to turn on all of the operating voltages, as a way to startup after power has been removed. The RTC block is implemented in a separate voltage domain. The block is supplied via a separate supply pin from a battery or other power source. The RTC block also contains 32 words (128 bytes) of very low voltage SRAM. This SRAM is able to hold its contents down to the minimum RTC operating voltage. 7.9.4.1 Features • Measures the passage of time in seconds. • 32-bit up and down seconds counters. • Ultra-low power design to support battery powered systems. • Dedicated 32 kHz oscillator. • An output pin is included to assist in waking up when the chip has had power removed to all functions except the RTC. • Two 32-bit match registers with interrupt option. • 32 words (128 bytes) of very low voltage SRAM. • The RTC and battery RAM power have an independent power domain and dedicated supply pins, which can be powered from a battery or power supply. Remark: The LPC3220/30/40/50 will run at voltages down to 0.9 V at frequencies below 14 MHz. However, the ARM core cannot access the RTC registers and battery RAM when the core supply voltage is at 0.9 V and the RTC supply is at 1.2 V. 7.9.5 Enhanced 32-bit timers/external event counters The LPC3220/30/40/50 includes six 32-bit Timer/Counters. The Timer/Counter is designed to count cycles of the system derived clock or an externally-supplied clock. It can optionally generate interrupts or perform other actions at specified timer values, based on four match registers. The Timer/Counter also includes four capture inputs to trap the timer value when an input signal transitions, optionally generating an interrupt. 7.9.5.1 Features • A 32-bit Timer/Counter with a programmable 32-bit pre-scaler. • Counter or Timer operation. • Up to four 32-bit capture channels per timer, that can take a snapshot of the timer value when an input signal transitions. A capture event may also optionally generate an interrupt. • Four 32-bit match registers that allow: – continuous operation with optional interrupt generation on match – stop timer on match with optional interrupt generation – reset timer on match with optional interrupt generation • Up to four external outputs corresponding to match registers, with the following capabilities: LPC3220_30_40_50 All information provided in this document is subject to legal disclaimers. © NXP B.V. 2011.

Product data sheet Rev. 2 — 20 October 2011 43 of 79 NXP Semiconductors LPC3220/30/40/50 16/32-bit ARM microcontrollers – set LOW on match – set HIGH on match – toggle on match – do nothing on match 7.9.6 High-speed timer The high-speed timer block is clocked by the main peripheral clock. The clock is first divided down in a 16-bit programmable pre-scale counter which clocks a 32-bit timer/counter. The high-speed timer includes three match registers that are compared to the timer/counter value. A match can generate an interrupt and cause the timer/counter to either continue to run, stop, or be reset. The high-speed timer also includes two capture registers that can take a snapshot of the timer/counter value when an input signal transitions. A capture event may also generate an interrupt. 7.9.6.1 Features • 32-bit timer/counter with programmable 16-bit pre-scaler. • Counter or timer operation. • Two 32-bit capture registers. • Three 32-bit match registers that allow: – Continuous operation with optional interrupt generation on match. – Stop timer on match with optional interrupt generation. – Reset timer on match with optional interrupt generation. • Pause control to stop counting when core is in debug state. 7.9.7 Pulse Width Modulators (PWMs) The LPC3220/30/40/50 provides two simple PWMs. They are clocked separately by either the main peripheral clock or the 32 kHz RTC clock. Both PWMs have a duty cycle programmable in 255 steps. 7.9.7.1 Features • Clocked by the main peripheral clock or the 32 kHz RTC clock. • Programmable 4-bit pre-scaler. • Duty cycle programmable in 255 steps. • Output frequency up to 50 kHz when using a 13 MHz peripheral clock. 7.9.8 Motor control pulse width modulator The Motor Control PWM (MCPWM) provides a set of features for three-phase AC and DC motor control applications in a single peripheral. The MCPWM can also be configured for use in other generalized timing, counting, capture, and compare applications. 7.9.8.1 Features • 32-bit timer • 32-bit period register LPC3220_30_40_50 All information provided in this document is subject to legal disclaimers. © NXP B.V. 2011. All rights reserved. Product data sheet Rev. 2 — 20 October 2011 44 of 79 NXP Semiconductors LPC3220/30/40/50 16/32-bit ARM microcontrollers • 32-bit pulse-width (match) register • 10-bit dead-time register and an associated 10-bit dead-time counter • 32-bit capture register • Two PWM (match) outputs (pins MCOA0/1/2 and MCOB0/1/2) with opposite polarities • Period interrupt, pulse-width interrupt, and capture interrupt 8. Basic architecture The LPC3220/30/40/50 is a general purpose ARM926EJ-S 32-bit microprocessor with a 32 kB instruction cache and a 32 kB data cache. The microcontroller offers high performance and very low power consumption. The ARM architecture is based on RISC principles, which results in the instruction set and related decode mechanism being much simpler than equivalent micro programmed CISCs. This simplicity results in a high instruction throughput and impressive real-time interrupt response from a small and cost-effective processor core. The ARM926EJ-S core employs a 5-stage pipeline so processing and memory system accesses can occur continuously. At any one point in time, several operations are in progress: subsequent instruction fetch, next instruction decode, instruction execution, memory access, and write-back. The combination of architectural enhancements gives the ARM9 about 30 % better performance than an ARM7 running at the same clock rate: • Approximately 1.3 clocks per instruction for the ARM926EJ-S compared to 1.9 clocks per instruction for ARM7TDMI. • Approximately 1.1 Dhrystone MIPS/MHz for the ARM926EJ-S compared to 0.9 Dhrystone MIPS/MHz for ARM7TDMI. The ARM926EJ-S processor also employs an operational state known as Thumb, which makes it ideally suited to high-volume applications with memory restrictions, or applications where code density is an issue. The key idea behind Thumb state is the use of a super-reduced instruction set. Essentially, the ARM926EJ-S processor core has two instruction sets: 1. The standard 32-bit ARM set 2. The 16-bit Thumb set The Thumb set’s smaller 16-bit instruction length allows it to approach twice the density of standard ARM code while retaining many of ARM’s 32-bit performance advantage over a traditional 16-bit processor using 16-bit registers. This is possible because Thumb code operates using the same 32-bit register set as ARM code. Thumb code size is up to 65 % smaller than ARM code size, and 160 % of the performance of an equivalent ARM processor connected to a 16-bit memory system. Additionally, the ARM926EJ-S core includes enhanced DSP instructions and multiplier, as well as an enhanced 32-bit MAC block.

An internal circuit ensures that the system correctly powers up in the absence of core power. During IO power-up this circuit takes care that the system is powered in a defined mode. The same is valid for core power-down. 10.3 Power consumption per peripheral [1] All three Ethernet clocks are in enabled in the MAC_CLK_CTRL register (see LPC32x0 User manual). Fig 4.

MMU and I-cache/D-cache are enabled. The VFP is turned on but not used. I2S-interface (channel 1), LCD, SLC NAND controller, I2C1-bus, SD card, touchscreen ADC, and UART 3 are turned on. All other peripherals are turned off. The AHB clock HCLK is identical to the core clock for frequencies up to 133 MHz, which is the maximum allowed HCLK frequency. For higher core frequencies, the HCLK PLL output must be divided by 2 to obtain an HCLK frequency lower than or equal to 133 MHz resulting in correspondingly lower power consumption by the AHB peripherals. Conditions: Tamb = 25 C; VDD_CORE = 1.2 V for core frequencies 208 MHz; VDD_CORE = 1.35 V for core frequencies > 208 MHz; VDD(IO) = 1.8 V.

[2] The ADC is monotonic; there are no missing codes. [3] The differential linearity error (ED) is the difference between the actual step width and the ideal step width. See Figure 6. [4] The integral non-linearity (EL(adj)) is the peak difference between the center of the steps of the actual and the ideal transfer curve after appropriate adjustment of gain and offset errors. See Figure 6. [5] The offset error (EO) is the absolute difference between the straight line which fits the actual curve and the straight line which fits the ideal curve. See Figure 6. [6] The gain error (EG) is the relative difference in percent between the straight line fitting the actual transfer curve after removing offset error, and the straight line which fits the ideal transfer curve. See Figure 6. [7] The absolute error (ET) is the maximum difference between the center of the steps of the actual transfer curve of the non-calibrated ADC and the ideal transfer curve. See Figure 6.

Product data sheet Rev. 4.3 — 22 April 2014 8 of 76 NXP Semiconductors LPC81xM 32-bit ARM Cortex-M0+ microcontroller 7.2 Pin description The pin description consists of two parts showing pin functions that are fixed to a certain package pin (see Table 4) and showing pin functions that can be assigned to any pin on the package through the switch matrix (see Table 5). The pin description table in Table 4 shows the pin functions that are fixed to specific pins on each package. These fixed-pin functions are selectable between GPIO and the comparator inputs, SWD, RESET, and the XTAL pins. By default, the GPIO function is selected except on pins PIO0_2, PIO0_3, and PIO0_5. JTAG functions are available in boundary scan mode only. Table 5 shows the the I2C, USART, SPI, and SCT pin functions, which can be assigned through the switch matrix to any pin that is not power or ground in place of the pin’s fixed functions. The following exceptions apply: For full I2C-bus compatibility, assign the I2C functions to the open-drain pins PIO0_11 and PIO0_10. Do not assign more than one output to any pin. However, more than one input can be assigned to a pin. Once any function is assigned to a pin, the pin’s GPIO functionality is disabled. Pin PIO0_4 triggers a wake-up from Deep power-down mode. If you need to wake up from Deep power-down mode via an external pin, do not assign any movable function to this pin. The JTAG functions TDO, TDI, TCK, TMS, and TRST are selected on pins PIO0_0 to PIO0_4 by hardware when the part is in boundary scan mode. Table 4.

SWDIO is enabled by default on this pin. In boundary scan mode: TMS (Test Mode Select). I/O - PIO0_2 — General purpose digital input/output pin. SWCLK/PIO0_3/ TCK 6 5 5 3 [2] I/O I; PU SWCLK — Serial Wire Clock. SWCLK is enabled by default on this pin. In boundary scan mode: TCK (Test Clock). I/O - PIO0_3 — General purpose digital input/output pin. PIO0_4/WAKEUP/ TRST 5 4 4 2 [6] I/O I; PU PIO0_4 — General purpose digital input/output pin. In ISP mode, this is the USART0 transmit pin U0_TXD. In boundary scan mode: TRST (Test Reset). This pin triggers a wake-up from Deep power-down mode. If you need to wake up from Deep power-down mode via an external pin, do not assign any movable function to this pin. This pin should be pulled HIGH externally before entering Deep power-down mode.

All rights reserved. Product data sheet Rev. 4.3 — 22 April 2014 17 of 76 NXP Semiconductors LPC81xM 32-bit ARM Cortex-M0+ microcontroller 8.9 Switch Matrix (SWM) The switch matrix controls the function of each digital or mixed analog/digital pin in a highly flexible way by allowing to connect many functions like the USART, SPI, SCT, and I2C functions to any pin that is not power or ground. These functions are called movable functions and are listed in Table 5. Functions that need specialized pads like the oscillator pins XTALIN and XTALOUT can be enabled or disabled through the switch matrix. These functions are called fixed-pin functions and cannot move to other pins. The fixed-pin functions are listed in Table 4. If a fixed-pin function is disabled, any other movable function can be assigned to this pin. 8.10 Fast General-Purpose parallel I/O (GPIO) Device pins that are not connected to a specific peripheral function are controlled by the GPIO registers. Pins may be dynamically configured as inputs or outputs. Multiple outputs can be set or cleared in one write operation. LPC81xM use accelerated GPIO functions: • GPIO registers are located on the ARM Cortex M0+ IO bus for fastest possible single-cycle I/O timing, allowing GPIO toggling with rates of up to 15 MHz.

Product data sheet Rev. 4.3 — 22 April 2014 18 of 76 NXP Semiconductors LPC81xM 32-bit ARM Cortex-M0+ microcontroller • An entire port value can be written in one instruction. • Mask, set, and clear operations are supported for the entire port. All GPIO port pins are fixed-pin functions that are enabled or disabled on the pins by the switch matrix. Therefore each GPIO port pin is assigned to one specific pin and cannot be moved to another pin. Except for pins SWDIO/PIO0_2, SWCLK/PIO0_3, and RESET/PIO0_5, the switch matrix enables the GPIO port pin function by default. 8.10.1 Features • Bit level port registers allow a single instruction to set and clear any number of bits in one write operation. • Direction control of individual bits. • All I/O default to inputs with internal pull-up resistors enabled after reset - except for the I2C-bus true open-drain pins PIO0_2 and PIO0_3. • Pull-up/pull-down configuration, repeater, and open-drain modes can be programmed through the IOCON block for each GPIO pin (see Figure 8). • 8.11 Pin interrupt/pattern match engine The pin interrupt block configures up to eight pins from all digital pins for providing eight external interrupts connected to the NVIC. The pattern match engine can be used, in conjunction with software, to create complex state machines based on pin inputs. Any digital pin, independently of the function selected through the switch matrix, can be configured through the SYSCON block as input to the pin interrupt or pattern match engine. The registers that control the pin interrupt or pattern match engine are located on the IO+ bus for fast single-cycle access. 8.11.1 Features • Pin interrupts – Up to eight pins can be selected from all digital pins as edge- or level-sensitive interrupt requests. Each request creates a separate interrupt in the NVIC. – Edge-sensitive interrupt pins can interrupt on rising or falling edges or both. – Level-sensitive interrupt pins can be HIGH- or LOW-active. – Pin interrupts can wake up the LPC81xM from sleep mode, deep-sleep mode, and power-down mode. • Pin interrupt pattern match engine – Up to eight pins can be selected from all digital pins to contribute to a boolean expression. The boolean expression consists of specified levels and/or transitions on various combinations of these pins. – Each minterm (product term) comprising the specified boolean expression can generate its own, dedicated interrupt request. – Any occurrence of a pattern match can be programmed to also generate an RXEV notification to the ARM CPU. The RXEV signal can be connected to a pin. LPC81XM All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved.

USART2 is available on parts LPC812M101JDH16 and LPC812M101JDH20 only. All USART functions are movable functions and are assigned to pins through the switch matrix. 8.12.1 Features • Maximum bit rates of 1.875 Mbit/s in asynchronous mode and 10 Mbit/s in synchronous mode for USART functions connected to all digital pins except PIO0_10 and PIO0_11. • 7, 8, or 9 data bits and 1 or 2 stop bits • Synchronous mode with master or slave operation.

Software flow control can be performed using Delta CTS detect, Transmit Disable control, and any GPIO as an RTS output. • Received data and status can optionally be read from a single register • Break generation and detection. • Receive data is 2 of 3 sample "voting". Status flag set when one sample differs. • Built-in Baud Rate Generator. • A fractional rate divider is shared among all UARTs. • Interrupts available for Receiver Ready, Transmitter Ready, Receiver Idle, change in receiver break detect, Framing error, Parity error, Overrun, Underrun, Delta CTS detect, and receiver sample noise detected. • Separate data and flow control loopback modes for testing. • Supported by on-chip ROM API. 8.13 SPI0/1 Remark: SPI0 is available on all LPC800 parts.

Product data sheet Rev. 4.3 — 22 April 2014 20 of 76 NXP Semiconductors LPC81xM 32-bit ARM Cortex-M0+ microcontroller • Data frames of 1 to 16 bits supported directly. Larger frames supported by software. • Master and slave operation. • Data can be transmitted to a slave without the need to read incoming data. This can be useful while setting up an SPI memory. • Control information can optionally be written along with data. This allows very versatile operation, including “any length” frames. • One Slave Select input/output with selectable polarity and flexible usage. Remark: Texas Instruments SSI and National Microwire modes are not supported. 8.14 I2C-bus interface The I2C-bus is bidirectional for inter-IC control using only two wires: a serial clock line (SCL) and a serial data line (SDA). Each device is recognized by a unique address and can operate as either a receiver-only device (e.g., an LCD driver) or a transmitter with the capability to both receive and send information (such as memory). Transmitters and/or receivers can operate in either master or slave mode, depending on whether the chip has to initiate a data transfer or is only addressed. The I2C is a multi-master bus and can be controlled by more than one bus master connected to it. The I2C-bus functions are movable functions and can be assigned through the switch matrix to any pin. However, only the true open-drain PIO0_10 and PIO0_11 provide the electrical characteristics to support the full I2C-bus specification (see Ref. 1). 8.14.1 Features • Supports standard and fast mode with data rates of up to 400 kbit/s. • Independent Master, Slave, and Monitor functions. • Supports both Multi-master and Multi-master with Slave functions. • Multiple I2C slave addresses supported in hardware. • One slave address can be selectively qualified with a bit mask or an address range in order to respond to multiple I2C bus addresses. • 10-bit addressing supported with software assist. • Supports SMBus. • Supported by on-chip ROM API. • If the I2C functions are connected to the true open-drain pins (PIO0_10 and PIO0_11), the I2C supports the full I2C-bus specification: – Fail-safe operation: When the power to an I2C-bus device is switched off, the SDA and SCL pins connected to the I2C-bus are floating and do not disturb the bus. – Supports Fast-mode Plus with bit rates up to 1 Mbit/s. 8.15 State-Configurable Timer/PWM (SCTimer/PWM) The state configurable timer (SCTimer/PWM or SCT) can perform basic 16-bit and 32-bit timer/counter functions with match outputs and external and internal capture inputs. In addition, the SCTimer/PWM can employ up to two different programmable states, which can change under the control of events, to provide complex timing patterns.

Product data sheet Rev. 4.3 — 22 April 2014 22 of 76 NXP Semiconductors LPC81xM 32-bit ARM Cortex-M0+ microcontroller • Optional warning interrupt can be generated at a programmable time prior to watchdog time-out. • Enabled by software but requires a hardware reset or a watchdog reset/interrupt to be disabled. • Incorrect feed sequence causes reset or interrupt if enabled. • Flag to indicate watchdog reset. • Programmable 24-bit timer with internal prescaler. • Selectable time period from (Tcy(WDCLK) 256 4) to (Tcy(WDCLK) 224 4) in multiples of Tcy(WDCLK) 4. • The Watchdog Clock (WDCLK)is generated by a the dedicated watchdog oscillator (WDOSC). 8.18 Self Wake-up Timer (WKT) The self wake-up timer is a 32-bit, loadable down-counter. Writing any non-zero value to this timer automatically enables the counter and launches a count-down sequence. When the counter is used as a wake-up timer, this write can occur just prior to entering a reduced power mode. 8.18.1 Features • 32-bit loadable down-counter. Counter starts automatically when a count value is loaded. Time-out generates an interrupt/wake up request. • The WKT resides in a separate, always-on power domain. • The WKT supports two clock sources: the low-power oscillator and the IRC. The low-power oscillator is located in the always-on power domain, so it can be used as the clock source in Deep power-down mode. • The WKT can be used for waking up the part from any reduced power mode, including Deep power-down mode, or for general-purpose timing. 8.19 Analog comparator (ACMP) The analog comparator with selectable hysteresis can compare voltage levels on external pins and internal voltages. After power-up and after switching the input channels of the comparator, the output of the voltage ladder must be allowed to settle to its stable value before it can be used as a comparator reference input. Settling times are given in Table 22. The analog comparator output is a movable function and is assigned to a pin through the switch matrix. The comparator inputs and the voltage reference are enabled or disabled on pins PIO0_0 and PIO0_1 through the switch matrix.

Following reset, the LPC81xM will operate from the IRC until switched by software. This allows systems to operate without any external crystal and the bootloader code to operate at a known frequency. See Figure 10 for an overview of the LPC81xM clock generation. 8.20.1.1 Internal RC Oscillator (IRC) The IRC may be used as the clock source for the WWDT, and/or as the clock that drives the PLL and subsequently the CPU. The nominal IRC frequency is 12 MHz. The IRC is trimmed to 1.5 % accuracy over the entire voltage and temperature range. The IRC can be used as a clock source for the CPU with or without using the PLL. The IRC frequency can be boosted to a higher frequency, up to the maximum CPU operating frequency, by the system PLL. Upon power-up or any chip reset, the LPC81xM use the IRC as the clock source. Software may later switch to one of the other available clock sources. 8.20.1.2 Crystal Oscillator (SysOsc) The crystal oscillator can be used as the clock source for the CPU, with or without using the PLL. The SysOsc operates at frequencies of 1 MHz to 25 MHz. This frequency can be boosted to a higher frequency, up to the maximum CPU operating frequency, by the system PLL. 8.20.1.3 Internal Low-power Oscillator and Watchdog Oscillator (WDOsc) The nominal frequency of the WDOsc is programmable between 9.4 kHz and 2.3 MHz. The frequency spread over silicon process variations is 40%. The WDOsc is a dedicated oscillator for the windowed WWDT. The internal low-power 10 kHz ( 40% accuracy) oscillator serves a the clock input to the WKT. This oscillator can be configured to run in all low power modes. 8.20.2 Clock input An external clock source can be supplied on the selected CLKIN pin. When selecting a clock signal for the CLKIN pin, follow the specifications for digital I/O pins in Table 9 “Static characteristics” and Table 15 “Dynamic characteristics: I/O pins[1]”. An 1.8 V external clock source can be supplied on the XTALIN pins to the system oscillator limiting the voltage of this signal ((see Section 14.2). The maximum frequency for both clock signals is 25 MHz. 8.20.3 System PLL The PLL accepts an input clock frequency in the range of 10 MHz to 25 MHz. The input frequency is multiplied up to a high frequency with a Current Controlled Oscillator (CCO). The multiplier can be an integer value from 1 to 32. The CCO operates in the range of 156 MHz to 320 MHz, so there is an additional divider in the loop to keep the CCO within its frequency range while the PLL is providing the desired output frequency.

Product data sheet Rev. 4.3 — 22 April 2014 26 of 76 NXP Semiconductors LPC81xM 32-bit ARM Cortex-M0+ microcontroller divider may be set to divide by 2, 4, 8, or 16 to produce the output clock. Since the minimum output divider value is 2, it is insured that the PLL output has a 50 % duty cycle. The PLL is turned off and bypassed following a chip reset and may be enabled by software. The program must configure and activate the PLL, wait for the PLL to lock, and then connect to the PLL as a clock source. The PLL settling time is nominally 100 s. 8.20.4 Clock output The LPC81xM features a clock output function that routes the IRC, the SysOsc, the watchdog oscillator, or the main clock to the CLKOUT function. The CLKOUT function can be connected to any digital pin through the switch matrix. 8.20.5 Wake-up process The LPC81xM begin operation at power-up by using the IRC as the clock source. This allows chip operation to resume quickly. If the SysOsc, the external clock source, or the PLL is needed by the application, software must enable these features and wait for them to stabilize before they are used as a clock source. 8.20.6 Power control The LPC81xM supports the ARM Cortex-M0 Sleep mode. The CPU clock rate may also be controlled as needed by changing clock sources, reconfiguring PLL values, and/or altering the CPU clock divider value. This allows a trade-off of power versus processing speed based on application requirements. In addition, a register is provided for shutting down the clocks to individual on-chip peripherals, allowing to fine-tune power consumption by eliminating all dynamic power use in any peripherals that are not required for the application. Selected peripherals have their own clock divider which provides even better power control. 8.20.6.1 Power profiles The power consumption in Active and Sleep modes can be optimized for the application through simple calls to the power profile API. The API is accessible through the on-chip ROM. The power configuration routine configures the LPC81xM for one of the following power modes: • Default mode corresponding to power configuration after reset. • CPU performance mode corresponding to optimized processing capability. • Efficiency mode corresponding to optimized balance of current consumption and CPU performance. • Low-current mode corresponding to lowest power consumption. In addition, the power profile includes routines to select the optimal PLL settings for a given system clock and PLL input clock. 8.20.6.2 Sleep mode When Sleep mode is entered, the clock to the core is stopped. Resumption from the Sleep mode does not need any special sequence but re-enabling the clock to the ARM core.

Product data sheet Rev. 4.3 — 22 April 2014 27 of 76 NXP Semiconductors LPC81xM 32-bit ARM Cortex-M0+ microcontroller In Sleep mode, execution of instructions is suspended until either a reset or interrupt occurs. Peripheral functions continue operation during Sleep mode and may generate interrupts to cause the processor to resume execution. Sleep mode eliminates dynamic power used by the processor itself, memory systems and related controllers, and internal buses. 8.20.6.3 Deep-sleep mode In Deep-sleep mode, the LPC81xM is in Sleep-mode and all peripheral clocks and all clock sources are off except for the IRC and watchdog oscillator or low-power oscillator if selected. The IRC output is disabled. In addition all analog blocks are shut down and the flash is in stand-by mode. In Deep-sleep mode, the application can keep the watchdog oscillator and the BOD circuit running for self-timed wake-up and BOD protection. The LPC81xM can wake up from Deep-sleep mode via a reset, digital pins selected as inputs to the pin interrupt block, a watchdog timer interrupt, or an interrupt from the USART (if the USART is configured in synchronous slave mode), the SPI, or the I2C blocks (in slave mode). Any interrupt used for waking up from Deep-sleep mode must be enabled in one of the SYSCON wake-up enable registers and the NVIC. Deep-sleep mode saves power and allows for short wake-up times. 8.20.6.4 Power-down mode In Power-down mode, the LPC81xM is in Sleep-mode and all peripheral clocks and all clock sources are off except for watchdog oscillator or low-power oscillator if selected. In addition all analog blocks and the flash are shut down. In Power-down mode, the application can keep the watchdog oscillator and the BOD circuit running for self-timed wake-up and BOD protection. The LPC81xM can wake up from Power-down mode via a reset, digital pins selected as inputs to the pin interrupt block, a watchdog timer interrupt, or an interrupt from the USART (if the USART is configured in synchronous slave mode), the SPI, or the I2C blocks (in slave mode). Any interrupt used for waking up from Power-down mode must be enabled in one of the SYSCON wake-up enable registers and the NVIC. Power-down mode reduces power consumption compared to Deep-sleep mode at the expense of longer wake-up times. 8.20.6.5 Deep power-down mode In Deep power-down mode, power is shut off to the entire chip except for the WAKEUP pin and the self wake-up timer if enabled. Four general-purpose registers are available to store information during Deep power-down mode. The LPC81xM can wake up from Deep power-down mode via the WAKEUP pin, or without an external signal by using the time-out of the self wake-up timer (see Section 8.18). The LPC81xM can be prevented from entering Deep power-down mode by setting a lock bit in the PMU block. Locking out Deep power-down mode enables the application to keep the watchdog timer or the BOD running at all times.

Product data sheet Rev. 4.3 — 22 April 2014 28 of 76 NXP Semiconductors LPC81xM 32-bit ARM Cortex-M0+ microcontroller When entering Deep power-down mode, an external pull-up resistor is required on the WAKEUP pin to hold it HIGH. Pull the RESET pin HIGH to prevent it from floating while in Deep power-down mode. 8.21 System control 8.21.1 Reset Reset has four sources on the LPC81xM: the RESET pin, the Watchdog reset, power-on reset (POR), and the BrownOut Detection (BOD) circuit. The RESET pin is a Schmitt trigger input pin. Assertion of chip reset by any source, once the operating voltage attains a usable level, starts the IRC and initializes the flash controller. A LOW-going pulse as short as 50 ns resets the part. When the internal Reset is removed, the processor begins executing at address 0, which is initially the Reset vector mapped from the boot block. At that point, all of the processor and peripheral registers have been initialized to predetermined values. In Deep power-down mode, an external pull-up resistor is required on the RESET pin. 8.21.2 Brownout detection The LPC81xM includes up to four levels for monitoring the voltage on the VDD pin. If this voltage falls below one of the selected levels, the BOD asserts an interrupt signal to the NVIC. This signal can be enabled for interrupt in the Interrupt Enable Register in the NVIC to cause a CPU interrupt. Alternatively, software can monitor the signal by reading a dedicated status register. Four threshold levels can be selected to cause a forced reset of the chip. Fig 11.

Product data sheet Rev. 4.3 — 22 April 2014 29 of 76 NXP Semiconductors LPC81xM 32-bit ARM Cortex-M0+ microcontroller 8.21.3 Code security (Code Read Protection - CRP) CRP provides different levels of security in the system so that access to the on-chip flash and use of the Serial Wire Debugger (SWD) and In-System Programming (ISP) can be restricted. Programming a specific pattern into a dedicated flash location invokes CRP. IAP commands are not affected by the CRP. In addition, ISP entry via the ISP entry pin can be disabled without enabling CRP. For details, see the LPC800 user manual. There are three levels of Code Read Protection: 1. CRP1 disables access to the chip via the SWD and allows partial flash update (excluding flash sector 0) using a limited set of the ISP commands. This mode is useful when CRP is required and flash field updates are needed but all sectors cannot be erased. 2. CRP2 disables access to the chip via the SWD and only allows full flash erase and update using a reduced set of the ISP commands. 3. Running an application with level CRP3 selected, fully disables any access to the chip via the SWD pins and the ISP. This mode effectively disables ISP override using the ISP entry pin as well. If necessary, the application must provide a flash update mechanism using IAP calls or using a call to the reinvoke ISP command to enable flash update via the USART. In addition to the three CRP levels, sampling of the ISP entry pin for valid user code can be disabled. For details, see the LPC800 user manual. 8.21.4 APB interface The APB peripherals are located on one APB bus. 8.21.5 AHBLite The AHBLite connects the CPU bus of the ARM Cortex-M0+ to the flash memory, the main static RAM, the CRC, and the ROM. CAUTION If level three Code Read Protection (CRP3) is selected, no future factory testing can be performed on the device.

Serial wire debug functions are supported in addition to a standard JTAG boundary scan. The ARM Cortex-M0+ is configured to support up to four breakpoints and two watch points. The Micro Trace Buffer is implemented on the LPC81xM. The RESET pin selects between the JTAG boundary scan (RESET = LOW) and the ARM SWD debug (RESET = HIGH). The ARM SWD debug port is disabled while the LPC81xM is in reset. The JTAG boundary scan pins are selected by hardware when the part is in boundary scan mode on pins PIO0_0 to PIO0_3 (see Table 4). To perform boundary scan testing, follow these steps: 1. Erase any user code residing in flash. 2. Power up the part with the RESET pin pulled HIGH externally. 3. Wait for at least 250 s. 4. Pull the RESET pin LOW externally. 5. Perform boundary scan operations. 6. Once the boundary scan operations are completed, assert the TRST pin to enable the SWD debug mode, and release the RESET pin (pull HIGH). Remark: The JTAG interface cannot be used for debug purposes.

Thermal characteristics The average chip junction temperature, Tj (C), can be calculated using the following equation: (1) • Tamb = ambient temperature (C), • Rth(j-a) = the package junction-to-ambient thermal resistance (C/W) • PD = sum of internal and I/O power dissipation The internal power dissipation is the product of IDD and VDD. The I/O power dissipation of the I/O pins is often small and many times can be negligible. However it can be significant in some applications. Table 8.

All rights reserved. Product data sheet Rev. 4.3 — 22 April 2014 49 of 76 NXP Semiconductors LPC81xM 32-bit ARM Cortex-M0+ microcontroller [3] tHD;DAT is the data hold time that is measured from the falling edge of SCL; applies to data in transmission and the acknowledge. [4] A device must internally provide a hold time of at least 300 ns for the SDA signal (with respect to the VIH(min) of the SCL signal) to bridge the undefined region of the falling edge of SCL. [5] Cb = total capacitance of one bus line in pF. [6] The maximum tf for the SDA and SCL bus lines is specified at 300 ns. The maximum fall time for the SDA output stage tf is specified at 250 ns. This allows series protection resistors to be connected in between the SDA and the SCL pins and the SDA/SCL bus lines without exceeding the maximum specified tf. [7] In Fast-mode Plus, fall time is specified the same for both output stage and bus timing. If series resistors are used, designers should allow for this when considering bus timing. [8] The maximum tHD;DAT could be 3.45 s and 0.9 s for Standard-mode and Fast-mode but must be less than the maximum of tVD;DAT or tVD;ACK by a transition time (see UM10204). This maximum must only be met if the device does not stretch the LOW period (tLOW) of the SCL signal. If the clock stretches the SCL, the data must be valid by the set-up time before it releases the clock. [9] tSU;DAT is the data set-up time that is measured with respect to the rising edge of SCL; applies to data in transmission and the acknowledge. [10] A Fast-mode I2C-bus device can be used in a Standard-mode I2C-bus system but the requirement tSU;DAT = 250 ns must then be met. This will automatically be the case if the device does not stretch the LOW period of the SCL signal. If such a device does stretch the LOW period of the SCL signal, it must output the next data bit to the SDA line tr(max) + tSU;DAT = 1000 + 250 = 1250 ns (according to the Standard-mode I2C-bus specification) before the SCL line is released. Also the acknowledge timing must meet this set-up time. Fig 30.

[2] IRC enabled, all peripherals off. [3] Watchdog oscillator disabled, Brown-Out Detect (BOD) disabled. [4] Self wakeup-timer disabled. Wake-up from deep power-down causes the LPC800 to go through entire reset process. The wake-up time measured is the time between when a wake-up pin is triggered to wake the device up from the low power modes and from when a GPIO output pin is set in the reset handler. 14.2 XTAL input The input voltage to the on-chip oscillators is limited to 1.8 V. If the oscillator is driven by a clock in slave mode, it is recommended that the input be coupled through a capacitor with Ci = 100 pF. To limit the input voltage to the specified range, choose an additional capacitor to ground Cg which attenuates the input voltage by a factor Ci/(Ci + Cg). In slave mode, a minimum of 200 mV(RMS) is needed. In slave mode the input clock signal should be coupled by means of a capacitor of 100 pF (Figure 35), with an amplitude between 200 mV (RMS) and 1000 mV (RMS). This corresponds to a square wave signal with a signal swing of between 280 mV and 1.4 V. The XTALOUT pin in this configuration can be left unconnected. External components and models used in oscillation mode are shown in Figure 36 and in Table 25 and Table 26. Since the feedback resistance is integrated on chip, only a crystal and the capacitances CX1 and CX2 need to be connected externally in case of fundamental mode oscillation (the fundamental frequency is represented by L, CL and Table 24.

Product data sheet Rev. 4.3 — 22 April 2014 60 of 76 NXP Semiconductors LPC81xM 32-bit ARM Cortex-M0+ microcontroller 14.3 XTAL Printed Circuit Board (PCB) layout guidelines The crystal should be connected on the PCB as close as possible to the oscillator input and output pins of the chip. Take care that the load capacitors Cx1,Cx2, and Cx3 in case of third overtone crystal usage have a common ground plane. The external components must also be connected to the ground plain. Loops must be made as small as possible in order to keep the noise coupled in via the PCB as small as possible. Also parasitics should stay as small as possible. Values of Cx1 and Cx2 should be chosen smaller accordingly to the increase in parasitics of the PCB layout.

Functional description 8.1 Architectural overview Remark: In the following, the notation LPC17xx refers to all parts: LPC1769/68/67/66/65/64/63. The ARM Cortex-M3 includes three AHB-Lite buses: the system bus, the I-code bus, and the D-code bus (see Figure 1). The I-code and D-code core buses are faster than the system bus and are used similarly to TCM interfaces: one bus dedicated for instruction fetch (I-code) and one bus for data access (D-code). The use of two core buses allows for simultaneous operations if concurrent operations target different devices. The LPC17xx use a multi-layer AHB matrix to connect the ARM Cortex-M3 buses and other bus masters to peripherals in a flexible manner that optimizes performance by allowing peripherals that are on different slaves ports of the matrix to be accessed simultaneously by different bus masters. 8.2 ARM Cortex-M3 processor The ARM Cortex-M3 is a general purpose, 32-bit microprocessor, which offers high performance and very low power consumption. The ARM Cortex-M3 offers many new features, including a Thumb-2 instruction set, low interrupt latency, hardware divide, interruptible/continuable multiple load and store instructions, automatic state save and restore for interrupts, tightly integrated interrupt controller with wake-up interrupt controller, and multiple core buses capable of simultaneous accesses. Pipeline techniques are employed so that all parts of the processing and memory systems can operate continuously. Typically, while one instruction is being executed, its successor is being decoded, and a third instruction is being fetched from memory. The ARM Cortex-M3 processor is described in detail in the Cortex-M3 Technical Reference Manual that can be found on official ARM website. 8.3 On-chip flash program memory The LPC17xx contain up to 512 kB of on-chip flash memory. A new two-port flash accelerator maximizes performance for use with the two fast AHB-Lite buses. 8.4 On-chip SRAM The LPC17xx contain a total of 64 kB on-chip static RAM memory. This includes the main 32 kB SRAM, accessible by the CPU and DMA controller on a higher-speed bus, and two additional 16 kB each SRAM blocks situated on a separate slave port on the AHB multilayer matrix. This architecture allows CPU and DMA accesses to be spread over three separate RAMs that can be accessed simultaneously. 8.5 Memory Protection Unit (MPU) The LPC17xx have a Memory Protection Unit (MPU) which can be used to improve the reliability of an embedded system by protecting critical data within the user application.

Product data sheet Rev. 9.4 — 4 April 2014 22 of 88 NXP Semiconductors LPC1769/68/67/66/65/64/63 32-bit ARM Cortex-M3 microcontroller The MPU allows separating processing tasks by disallowing access to each other's data, disabling access to memory regions, allowing memory regions to be defined as read-only and detecting unexpected memory accesses that could potentially break the system. The MPU separates the memory into distinct regions and implements protection by preventing disallowed accesses. The MPU supports up to 8 regions each of which can be divided into 8 subregions. Accesses to memory locations that are not defined in the MPU regions, or not permitted by the region setting, will cause the Memory Management Fault exception to take place. 8.6 Memory map The LPC17xx incorporates several distinct memory regions, shown in the following figures. Figure 5 shows the overall map of the entire address space from the user program viewpoint following reset. The interrupt vector area supports address remapping. The AHB peripheral area is 2 MB in size and is divided to allow for up to 128 peripherals. The APB peripheral area is 1 MB in size and is divided to allow for up to 64 peripherals. Each peripheral of either type is allocated 16 kB of space. This allows simplifying the address decoding for each peripheral. xxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxx x x x xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxx xx xx xxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxx xxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxx x x xxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxx xxx LPC1769_68_67_66_65_64_63 All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014.

Product data sheet Rev. 9.4 — 4 April 2014 24 of 88 NXP Semiconductors LPC1769/68/67/66/65/64/63 32-bit ARM Cortex-M3 microcontroller 8.7 Nested Vectored Interrupt Controller (NVIC) The NVIC is an integral part of the Cortex-M3. The tight coupling to the CPU allows for low interrupt latency and efficient processing of late arriving interrupts. 8.7.1 Features • Controls system exceptions and peripheral interrupts • In the LPC17xx, the NVIC supports 33 vectored interrupts • 32 programmable interrupt priority levels, with hardware priority level masking • Relocatable vector table • Non-Maskable Interrupt (NMI) • Software interrupt generation 8.7.2 Interrupt sources Each peripheral device has one interrupt line connected to the NVIC but may have several interrupt flags. Individual interrupt flags may also represent more than one interrupt source. Any pin on Port 0 and Port 2 (total of 42 pins) regardless of the selected function, can be programmed to generate an interrupt on a rising edge, a falling edge, or both. 8.8 Pin connect block The pin connect block allows selected pins of the microcontroller to have more than one function. Configuration registers control the multiplexers to allow connection between the pin and the on-chip peripherals. Peripherals should be connected to the appropriate pins prior to being activated and prior to any related interrupt(s) being enabled. Activity of any enabled peripheral function that is not mapped to a related pin should be considered undefined. Most pins can also be configured as open-drain outputs or to have a pull-up, pull-down, or no resistor enabled. 8.9 General purpose DMA controller The GPDMA is an AMBA AHB compliant peripheral allowing selected peripherals to have DMA support. The GPDMA enables peripheral-to-memory, memory-to-peripheral, peripheral-to-peripheral, and memory-to-memory transactions. The source and destination areas can each be either a memory region or a peripheral, and can be accessed through the AHB master. The GPDMA controller allows data transfers between the USB and Ethernet controllers and the various on-chip SRAM areas. The supported APB peripherals are SSP0/1, all UARTs, the I2S-bus interface, the ADC, and the DAC. Two match signals for each timer can be used to trigger DMA transfers. Remark: The Ethernet controller is available on parts LPC1769/68/67/66/64. The USB controller is available on parts LPC1769/68/66/65/64. The I2S-bus interface is available on parts LPC1769/68/67/66/65. The DAC is available on parts LPC1769/68/67/66/65/63.

Each channel can support an unidirectional transfer. • 16 DMA request lines. • Single DMA and burst DMA request signals. Each peripheral connected to the DMA Controller can assert either a burst DMA request or a single DMA request. The DMA burst size is set by programming the DMA Controller. • Memory-to-memory, memory-to-peripheral, peripheral-to-memory, and peripheral-to-peripheral transfers are supported. • Scatter or gather DMA is supported through the use of linked lists. This means that the source and destination areas do not have to occupy contiguous areas of memory. • Hardware DMA channel priority. • AHB slave DMA programming interface. The DMA Controller is programmed by writing to the DMA control registers over the AHB slave interface. • One AHB bus master for transferring data. The interface transfers data when a DMA request goes active. • 32-bit AHB master bus width. • Incrementing or non-incrementing addressing for source and destination. • Programmable DMA burst size. The DMA burst size can be programmed to more efficiently transfer data. • Internal four-word FIFO per channel. • Supports 8, 16, and 32-bit wide transactions. • Big-endian and little-endian support. The DMA Controller defaults to little-endian mode on reset. • An interrupt to the processor can be generated on a DMA completion or when a DMA error has occurred. • Raw interrupt status. The DMA error and DMA count raw interrupt status can be read prior to masking. 8.10 Fast general purpose parallel I/O Device pins that are not connected to a specific peripheral function are controlled by the GPIO registers. Pins may be dynamically configured as inputs or outputs. Separate registers allow setting or clearing any number of outputs simultaneously. The value of the output register may be read back as well as the current state of the port pins. LPC17xx use accelerated GPIO functions: • GPIO registers are accessed through the AHB multilayer bus so that the fastest possible I/O timing can be achieved. • Mask registers allow treating sets of port bits as a group, leaving other bits unchanged. • All GPIO registers are byte and half-word addressable. • Entire port value can be written in one instruction. • Support for Cortex-M3 bit banding. • Support for use with the GPDMA controller.

The edge detection is asynchronous, so it may operate when clocks are not present such as during Power-down mode. Each enabled interrupt can be used to wake up the chip from Power-down mode. 8.10.1 Features • Bit level set and clear registers allow a single instruction to set or clear any number of bits in one port. • Direction control of individual bits. • All I/O default to inputs after reset. • Pull-up/pull-down resistor configuration and open-drain configuration can be programmed through the pin connect block for each GPIO pin. 8.11 Ethernet Remark: The Ethernet controller is available on parts LPC1769/68/67/66/64. The Ethernet block supports bus clock rates of up to 100 MHz (LPC1768/67/66/64) or 120 MHz (LPC1769). See Table 2. The Ethernet block contains a full featured 10 Mbit/s or 100 Mbit/s Ethernet MAC designed to provide optimized performance through the use of DMA hardware acceleration. Features include a generous suite of control registers, half or full duplex operation, flow control, control frames, hardware acceleration for transmit retry, receive packet filtering and wake-up on LAN activity. Automatic frame transmission and reception with scatter-gather DMA off-loads many operations from the CPU. The Ethernet block and the CPU share the ARM Cortex-M3 D-code and system bus through the AHB-multilayer matrix to access the various on-chip SRAM blocks for Ethernet data, control, and status information.

SPI is a full duplex serial interface designed to handle multiple masters and slaves connected to a given bus. Only a single master and a single slave can communicate on the interface during a given data transfer. During a data transfer the master always sends 8 bits to 16 bits of data to the slave, and the slave always sends 8 bits to 16 bits of data to the master. 8.17.1 Features • Maximum SPI data bit rate of 12.5 Mbit/s • Compliant with SPI specification • Synchronous, serial, full duplex communication • Combined SPI master and slave • Maximum data bit rate of one eighth of the input clock rate • 8 bits to 16 bits per transfer 8.18 SSP serial I/O controller The LPC17xx contain two SSP controllers.

Product data sheet Rev. 9.4 — 4 April 2014 32 of 88 NXP Semiconductors LPC1769/68/67/66/65/64/63 32-bit ARM Cortex-M3 microcontroller 8.20 I2S-bus serial I/O controllers Remark: The I2S-bus interface is available on parts LPC1769/68/67/66/65/63. See Table 2. The I2S-bus provides a standard communication interface for digital audio applications. The I2S-bus specification defines a 3-wire serial bus using one data line, one clock line, and one word select signal. The basic I2S-bus connection has one master, which is always the master, and one slave. The I2S-bus interface provides a separate transmit and receive channel, each of which can operate as either a master or a slave. 8.20.1 Features • The interface has separate input/output channels each of which can operate in master or slave mode. • Capable of handling 8-bit, 16-bit, and 32-bit word sizes. • Mono and stereo audio data supported. • The sampling frequency can range from 16 kHz to 96 kHz (16, 22.05, 32, 44.1, 48, 96) kHz. • Support for an audio master clock. • Configurable word select period in master mode (separately for I2S-bus input and output). • Two 8-word FIFO data buffers are provided, one for transmit and one for receive. • Generates interrupt requests when buffer levels cross a programmable boundary. • Two DMA requests, controlled by programmable buffer levels. These are connected to the GPDMA block. • Controls include reset, stop and mute options separately for I2S-bus input and I2S-bus output. 8.21 General purpose 32-bit timers/external event counters The LPC17xx include four 32-bit timer/counters. The timer/counter is designed to count cycles of the system derived clock or an externally-supplied clock. It can optionally generate interrupts, generate timed DMA requests, or perform other actions at specified timer values, based on four match registers. Each timer/counter also includes two capture inputs to trap the timer value when an input signal transitions, optionally generating an interrupt. 8.21.1 Features • A 32-bit timer/counter with a programmable 32-bit prescaler. • Counter or timer operation. • Two 32-bit capture channels per timer, that can take a snapshot of the timer value when an input signal transitions. A capture event may also generate an interrupt. • Four 32-bit match registers that allow: – Continuous operation with optional interrupt generation on match. – Stop timer on match with optional interrupt generation. – Reset timer on match with optional interrupt generation.

Product data sheet Rev. 9.4 — 4 April 2014 33 of 88 NXP Semiconductors LPC1769/68/67/66/65/64/63 32-bit ARM Cortex-M3 microcontroller • Up to four external outputs corresponding to match registers, with the following capabilities: – Set LOW on match. – Set HIGH on match. – Toggle on match. – Do nothing on match. • Up to two match registers can be used to generate timed DMA requests. 8.22 Pulse width modulator The PWM is based on the standard Timer block and inherits all of its features, although only the PWM function is pinned out on the LPC17xx. The Timer is designed to count cycles of the system derived clock and optionally switch pins, generate interrupts or perform other actions when specified timer values occur, based on seven match registers. The PWM function is in addition to these features, and is based on match register events. The ability to separately control rising and falling edge locations allows the PWM to be used for more applications. For instance, multi-phase motor control typically requires three non-overlapping PWM outputs with individual control of all three pulse widths and positions. Two match registers can be used to provide a single edge controlled PWM output. One match register (PWMMR0) controls the PWM cycle rate, by resetting the count upon match. The other match register controls the PWM edge position. Additional single edge controlled PWM outputs require only one match register each, since the repetition rate is the same for all PWM outputs. Multiple single edge controlled PWM outputs will all have a rising edge at the beginning of each PWM cycle, when an PWMMR0 match occurs. Three match registers can be used to provide a PWM output with both edges controlled. Again, the PWMMR0 match register controls the PWM cycle rate. The other match registers control the two PWM edge positions. Additional double edge controlled PWM outputs require only two match registers each, since the repetition rate is the same for all PWM outputs. With double edge controlled PWM outputs, specific match registers control the rising and falling edge of the output. This allows both positive going PWM pulses (when the rising edge occurs prior to the falling edge), and negative going PWM pulses (when the falling edge occurs prior to the rising edge). 8.22.1 Features • One PWM block with Counter or Timer operation (may use the peripheral clock or one of the capture inputs as the clock source). • Seven match registers allow up to 6 single edge controlled or 3 double edge controlled PWM outputs, or a mix of both types. The match registers also allow: – Continuous operation with optional interrupt generation on match. – Stop timer on match with optional interrupt generation. – Reset timer on match with optional interrupt generation.

Single edge controlled PWM outputs all go high at the beginning of each cycle unless the output is a constant low. Double edge controlled PWM outputs can have either edge occur at any position within a cycle. This allows for both positive going and negative going pulses. • Pulse period and width can be any number of timer counts. This allows complete flexibility in the trade-off between resolution and repetition rate. All PWM outputs will occur at the same repetition rate. • Double edge controlled PWM outputs can be programmed to be either positive going or negative going pulses. • Match register updates are synchronized with pulse outputs to prevent generation of erroneous pulses. Software must ‘release’ new match values before they can become effective. • May be used as a standard 32-bit timer/counter with a programmable 32-bit prescaler if the PWM mode is not enabled. 8.23 Motor control PWM The motor control PWM is a specialized PWM supporting 3-phase motors and other combinations. Feedback inputs are provided to automatically sense rotor position and use that information to ramp speed up or down. An abort input is also provided that causes the PWM to immediately release all motor drive outputs. At the same time, the motor control PWM is highly configurable for other generalized timing, counting, capture, and compare applications. 8.24 Quadrature Encoder Interface (QEI) A quadrature encoder, also known as a 2-channel incremental encoder, converts angular displacement into two pulse signals. By monitoring both the number of pulses and the relative phase of the two signals, the user can track the position, direction of rotation, and velocity. In addition, a third channel, or index signal, can be used to reset the position counter. The quadrature encoder interface decodes the digital pulses from a quadrature encoder wheel to integrate position over time and determine direction of rotation. In addition, the QEI can capture the velocity of the encoder wheel. 8.24.1 Features • Tracks encoder position. • Increments/decrements depending on direction. • Programmable for 2 or 4 position counting. • Velocity capture using built-in timer. • Velocity compare function with “less than” interrupt. • Uses 32-bit registers for position and velocity. • Three position compare registers with interrupts. • Index counter for revolution counting. • Index compare register with interrupts. • Can combine index and position interrupts to produce an interrupt for whole and partial revolution displacement.

Any bits of the timer/compare can be masked such that they do not contribute to the match detection. The repetitive interrupt timer can be used to create an interrupt that repeats at predetermined intervals. 8.25.1 Features • 32-bit counter running from PCLK. Counter can be free-running or be reset by a generated interrupt. • 32-bit compare value. • 32-bit compare mask. An interrupt is generated when the counter value equals the compare value, after masking. This allows for combinations not possible with a simple compare. 8.26 ARM Cortex-M3 system tick timer The ARM Cortex-M3 includes a system tick timer (SYSTICK) that is intended to generate a dedicated SYSTICK exception at a 10 ms interval. In the LPC17xx, this timer can be clocked from the internal AHB clock or from a device pin. 8.27 Watchdog timer The purpose of the watchdog is to reset the microcontroller within a reasonable amount of time if it enters an erroneous state. When enabled, the watchdog will generate a system reset if the user program fails to ‘feed’ (or reload) the watchdog within a predetermined amount of time. 8.27.1 Features • Internally resets chip if not periodically reloaded. • Debug mode. • Enabled by software but requires a hardware reset or a watchdog reset/interrupt to be disabled. • Incorrect/Incomplete feed sequence causes reset/interrupt if enabled. • Flag to indicate watchdog reset. • Programmable 32-bit timer with internal prescaler. • Selectable time period from (Tcy(WDCLK) 256 4) to (Tcy(WDCLK) 232 4) in multiples of Tcy(WDCLK) 4. • The Watchdog Clock (WDCLK) source can be selected from the Internal RC (IRC) oscillator, the RTC oscillator, or the APB peripheral clock. This gives a wide range of potential timing choices of Watchdog operation under different power reduction LPC1769_68_67_66_65_64_63 All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014.

It also provides the ability to run the WDT from an entirely internal source that is not dependent on an external crystal and its associated components and wiring for increased reliability. • Includes lock/safe feature. 8.28 RTC and backup registers The RTC is a set of counters for measuring time when system power is on, and optionally when it is off. The RTC on the LPC17xx is designed to have extremely low power consumption, i.e. less than 1 A. The RTC will typically run from the main chip power supply, conserving battery power while the rest of the device is powered up. When operating from a battery, the RTC will continue working down to 2.1 V. Battery power can be provided from a standard 3 V Lithium button cell. An ultra-low power 32 kHz oscillator will provide a 1 Hz clock to the time counting portion of the RTC, moving most of the power consumption out of the time counting function. The RTC includes a calibration mechanism to allow fine-tuning the count rate in a way that will provide less than 1 second per day error when operated at a constant voltage and temperature. A clock output function (see Section 8.29.4) makes measuring the oscillator rate easy and accurate. The RTC contains a small set of backup registers (20 bytes) for holding data while the main part of the LPC17xx is powered off. The RTC includes an alarm function that can wake up the LPC17xx from all reduced power modes with a time resolution of 1 s. 8.28.1 Features • Measures the passage of time to maintain a calendar and clock. • Ultra low power design to support battery powered systems. • Provides Seconds, Minutes, Hours, Day of Month, Month, Year, Day of Week, and Day of Year. • Dedicated power supply pin can be connected to a battery or to the main 3.3 V. • Periodic interrupts can be generated from increments of any field of the time registers. • Backup registers (20 bytes) powered by VBAT. • RTC power supply is isolated from the rest of the chip. 8.29 Clocking and power control 8.29.1 Crystal oscillators The LPC17xx include three independent oscillators. These are the main oscillator, the IRC oscillator, and the RTC oscillator. Each oscillator can be used for more than one purpose as required in a particular application. Any of the three clock sources can be chosen by software to drive the main PLL and ultimately the CPU. Following reset, the LPC17xx will operate from the Internal RC oscillator until switched by software. This allows systems to operate without any external crystal and the bootloader code to operate at a known frequency.

Product data sheet Rev. 9.4 — 4 April 2014 37 of 88 NXP Semiconductors LPC1769/68/67/66/65/64/63 32-bit ARM Cortex-M3 microcontroller See Figure 6 for an overview of the LPC17xx clock generation. 8.29.1.1 Internal RC oscillator The IRC may be used as the clock source for the WDT, and/or as the clock that drives the PLL and subsequently the CPU. The nominal IRC frequency is 4 MHz. The IRC is trimmed to 1 % accuracy over the entire voltage and temperature range. Upon power-up or any chip reset, the LPC17xx use the IRC as the clock source. Software may later switch to one of the other available clock sources. 8.29.1.2 Main oscillator The main oscillator can be used as the clock source for the CPU, with or without using the PLL. The main oscillator also provides the clock source for the dedicated USB PLL. The main oscillator operates at frequencies of 1 MHz to 25 MHz. This frequency can be boosted to a higher frequency, up to the maximum CPU operating frequency, by the main PLL. The clock selected as the PLL input is PLLCLKIN. The ARM processor clock frequency is referred to as CCLK elsewhere in this document. The frequencies of PLLCLKIN and CCLK are the same value unless the PLL is active and connected. The clock frequency for each peripheral can be selected individually and is referred to as PCLK. Refer to Section 8.29.2 for additional information. 8.29.1.3 RTC oscillator The RTC oscillator can be used as the clock source for the RTC block, the main PLL, and/or the CPU. Fig 6.

All rights reserved. Product data sheet Rev. 9.4 — 4 April 2014 38 of 88 NXP Semiconductors LPC1769/68/67/66/65/64/63 32-bit ARM Cortex-M3 microcontroller 8.29.2 Main PLL (PLL0) The PLL0 accepts an input clock frequency in the range of 32 kHz to 25 MHz. The input frequency is multiplied up to a high frequency, then divided down to provide the actual clock used by the CPU and/or the USB block. The PLL0 input, in the range of 32 kHz to 25 MHz, may initially be divided down by a value ‘N’, which may be in the range of 1 to 256. This input division provides a wide range of output frequencies from the same input frequency. Following the PLL0 input divider is the PLL0 multiplier. This can multiply the input divider output through the use of a Current Controlled Oscillator (CCO) by a value ‘M’, in the range of 1 through 32768. The resulting frequency must be in the range of 275 MHz to 550 MHz. The multiplier works by dividing the CCO output by the value of M, then using a phase-frequency detector to compare the divided CCO output to the multiplier input. The error value is used to adjust the CCO frequency. The PLL0 is turned off and bypassed following a chip Reset and by entering Power-down mode. PLL0 is enabled by software only. The program must configure and activate the PLL0, wait for the PLL0 to lock, and then connect to the PLL0 as a clock source. 8.29.3 USB PLL (PLL1) The LPC17xx contain a second, dedicated USB PLL1 to provide clocking for the USB interface. The PLL1 receives its clock input from the main oscillator only and provides a fixed 48 MHz clock to the USB block only. The PLL1 is disabled and powered off on reset. If the PLL1 is left disabled, the USB clock will be supplied by the 48 MHz clock from the main PLL0. The PLL1 accepts an input clock frequency in the range of 10 MHz to 25 MHz only. The input frequency is multiplied up the range of 48 MHz for the USB clock using a Current Controlled Oscillators (CCO). It is insured that the PLL1 output has a 50 % duty cycle. 8.29.4 RTC clock output The LPC17xx feature a clock output function intended for synchronizing with external devices and for use during system development to allow checking the internal clocks CCLK, IRC clock, main crystal, RTC clock, and USB clock in the outside world. The RTC clock output allows tuning the RTC frequency without probing the pin, which would distort the results. 8.29.5 Wake-up timer The LPC17xx begin operation at power-up and when awakened from Power-down mode by using the 4 MHz IRC oscillator as the clock source. This allows chip operation to resume quickly. If the main oscillator or the PLL is needed by the application, software will need to enable these features and wait for them to stabilize before they are used as a clock source. When the main oscillator is initially activated, the wake-up timer allows software to ensure that the main oscillator is fully functional before the processor uses it as a clock source and starts to execute instructions. This is important at power on, all types of Reset, and LPC1769_68_67_66_65_64_63 All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014.

Product data sheet Rev. 9.4 — 4 April 2014 39 of 88 NXP Semiconductors LPC1769/68/67/66/65/64/63 32-bit ARM Cortex-M3 microcontroller whenever any of the aforementioned functions are turned off for any reason. Since the oscillator and other functions are turned off during Power-down mode, any wake-up of the processor from Power-down mode makes use of the wake-up timer. The Wake-up Timer monitors the crystal oscillator to check whether it is safe to begin code execution. When power is applied to the chip, or when some event caused the chip to exit Power-down mode, some time is required for the oscillator to produce a signal of sufficient amplitude to drive the clock logic. The amount of time depends on many factors, including the rate of VDD(3V3) ramp (in the case of power on), the type of crystal and its electrical characteristics (if a quartz crystal is used), as well as any other external circuitry (e.g., capacitors), and the characteristics of the oscillator itself under the existing ambient conditions. 8.29.6 Power control The LPC17xx support a variety of power control features. There are four special modes of processor power reduction: Sleep mode, Deep-sleep mode, Power-down mode, and Deep power-down mode. The CPU clock rate may also be controlled as needed by changing clock sources, reconfiguring PLL values, and/or altering the CPU clock divider value. This allows a trade-off of power versus processing speed based on application requirements. In addition, Peripheral Power Control allows shutting down the clocks to individual on-chip peripherals, allowing fine tuning of power consumption by eliminating all dynamic power use in any peripherals that are not required for the application. Each of the peripherals has its own clock divider which provides even better power control. Integrated PMU (Power Management Unit) automatically adjust internal regulators to minimize power consumption during Sleep, Deep sleep, Power-down, and Deep power-down modes. The LPC17xx also implement a separate power domain to allow turning off power to the bulk of the device while maintaining operation of the RTC and a small set of registers for storing data during any of the power-down modes. 8.29.6.1 Sleep mode When Sleep mode is entered, the clock to the core is stopped. Resumption from the Sleep mode does not need any special sequence but re-enabling the clock to the ARM core. In Sleep mode, execution of instructions is suspended until either a Reset or interrupt occurs. Peripheral functions continue operation during Sleep mode and may generate interrupts to cause the processor to resume execution. Sleep mode eliminates dynamic power used by the processor itself, memory systems and related controllers, and internal buses. 8.29.6.2 Deep-sleep mode In Deep-sleep mode, the oscillator is shut down and the chip receives no internal clocks. The processor state and registers, peripheral registers, and internal SRAM values are preserved throughout Deep-sleep mode and the logic levels of chip pins remain static. The output of the IRC is disabled but the IRC is not powered down for a fast wake-up later. The RTC oscillator is not stopped because the RTC interrupts may be used as the wake-up source. The PLL is automatically turned off and disconnected. The CCLK and USB clock dividers automatically get reset to zero.

Product data sheet Rev. 9.4 — 4 April 2014 40 of 88 NXP Semiconductors LPC1769/68/67/66/65/64/63 32-bit ARM Cortex-M3 microcontroller The Deep-sleep mode can be terminated and normal operation resumed by either a Reset or certain specific interrupts that are able to function without clocks. Since all dynamic operation of the chip is suspended, Deep-sleep mode reduces chip power consumption to a very low value. Power to the flash memory is left on in Deep-sleep mode, allowing a very quick wake-up. On wake-up from Deep-sleep mode, the code execution and peripherals activities will resume after 4 cycles expire if the IRC was used before entering Deep-sleep mode. If the main external oscillator was used, the code execution will resume when 4096 cycles expire. PLL and clock dividers need to be reconfigured accordingly. 8.29.6.3 Power-down mode Power-down mode does everything that Deep-sleep mode does, but also turns off the power to the IRC oscillator and the flash memory. This saves more power but requires waiting for resumption of flash operation before execution of code or data access in the flash memory can be accomplished. On the wake-up of Power-down mode, if the IRC was used before entering Power-down mode, it will take IRC 60 s to start-up. After this 4 IRC cycles will expire before the code execution can then be resumed if the code was running from SRAM. In the meantime, the flash wake-up timer then counts 4 MHz IRC clock cycles to make the 100 s flash start-up time. When it times out, access to the flash will be allowed. Users need to reconfigure the PLL and clock dividers accordingly. 8.29.6.4 Deep power-down mode The Deep power-down mode can only be entered from the RTC block. In Deep power-down mode, power is shut off to the entire chip with the exception of the RTC module and the RESET pin. The LPC17xx can wake up from Deep power-down mode via the RESET pin or an alarm match event of the RTC. 8.29.6.5 Wake-up interrupt controller The Wake-up Interrupt Controller (WIC) allows the CPU to automatically wake up from any enabled priority interrupt that can occur while the clocks are stopped in Deep sleep, Power-down, and Deep power-down modes. The WIC works in connection with the Nested Vectored Interrupt Controller (NVIC). When the CPU enters Deep sleep, Power-down, or Deep power-down mode, the NVIC sends a mask of the current interrupt situation to the WIC.This mask includes all of the interrupts that are both enabled and of sufficient priority to be serviced immediately. With this information, the WIC simply notices when one of the interrupts has occurred and then it wakes up the CPU. The WIC eliminates the need to periodically wake up the CPU and poll the interrupts resulting in additional power savings. 8.29.7 Peripheral power control A Power Control for Peripherals feature allows individual peripherals to be turned off if they are not needed in the application, resulting in additional power savings.

On the LPC17xx, I/O pads are powered by the 3.3 V (VDD(3V3)) pins, while the VDD(REG)(3V3) pin powers the on-chip voltage regulator which in turn provides power to the CPU and most of the peripherals. Depending on the LPC17xx application, a design can use two power options to manage power consumption. The first option assumes that power consumption is not a concern and the design ties the VDD(3V3) and VDD(REG)(3V3) pins together. This approach requires only one 3.3 V power supply for both pads, the CPU, and peripherals. While this solution is simple, it does not support powering down the I/O pad ring “on the fly” while keeping the CPU and peripherals alive. The second option uses two power supplies; a 3.3 V supply for the I/O pads (VDD(3V3)) and a dedicated 3.3 V supply for the CPU (VDD(REG)(3V3)). Having the on-chip voltage regulator powered independently from the I/O pad ring enables shutting down of the I/O pad power supply “on the fly”, while the CPU and peripherals stay active. The VBAT pin supplies power only to the RTC domain. The RTC requires a minimum of power to operate, which can be supplied by an external battery. The device core power (VDD(REG)(3V3)) is used to operate the RTC whenever VDD(REG)(3V3) is present. Therefore, there is no power drain from the RTC battery when VDD(REG)(3V3) is available.

The RESET pin is a Schmitt trigger input pin. Assertion of chip Reset by any source, once the operating voltage attains a usable level, causes the RSTOUT pin to go LOW and starts the wake-up timer (see description in Section 8.29.5). The wake-up timer ensures that reset remains asserted until the external Reset is de-asserted, the oscillator is running, a fixed number of clocks have passed, and the flash controller has completed its initialization. Once reset is de-asserted, or, in case of a BOD-triggered reset, once the voltage rises above the BOD threshold, the RSTOUT pin goes HIGH. When the internal Reset is removed, the processor begins executing at address 0, which is initially the Reset vector mapped from the Boot Block. At that point, all of the processor and peripheral registers have been initialized to predetermined values. Fig 7.

Product data sheet Rev. 9.4 — 4 April 2014 43 of 88 NXP Semiconductors LPC1769/68/67/66/65/64/63 32-bit ARM Cortex-M3 microcontroller 8.30.2 Brownout detection The LPC17xx include 2-stage monitoring of the voltage on the VDD(REG)(3V3) pins. If this voltage falls below 2.2 V, the BOD asserts an interrupt signal to the Vectored Interrupt Controller. This signal can be enabled for interrupt in the Interrupt Enable Register in the NVIC in order to cause a CPU interrupt; if not, software can monitor the signal by reading a dedicated status register. The second stage of low-voltage detection asserts reset to inactivate the LPC17xx when the voltage on the VDD(REG)(3V3) pins falls below 1.85 V. This reset prevents alteration of the flash as operation of the various elements of the chip would otherwise become unreliable due to low voltage. The BOD circuit maintains this reset down below 1 V, at which point the power-on reset circuitry maintains the overall reset. Both the 2.2 V and 1.85 V thresholds include some hysteresis. In normal operation, this hysteresis allows the 2.2 V detection to reliably interrupt, or a regularly executed event loop to sense the condition. 8.30.3 Code security (Code Read Protection - CRP) This feature of the LPC17xx allows user to enable different levels of security in the system so that access to the on-chip flash and use of the JTAG and ISP can be restricted. When needed, CRP is invoked by programming a specific pattern into a dedicated flash location. IAP commands are not affected by the CRP. There are three levels of the Code Read Protection. CRP1 disables access to chip via the JTAG and allows partial flash update (excluding flash sector 0) using a limited set of the ISP commands. This mode is useful when CRP is required and flash field updates are needed but all sectors can not be erased. CRP2 disables access to chip via the JTAG and only allows full flash erase and update using a reduced set of the ISP commands. Running an application with level CRP3 selected fully disables any access to chip via the JTAG pins and the ISP. This mode effectively disables ISP override using P2[10] pin, too. It is up to the user’s application to provide (if needed) flash update mechanism using IAP calls or call reinvoke ISP command to enable flash update via UART0. 8.30.4 APB interface The APB peripherals are split into two separate APB buses in order to distribute the bus bandwidth and thereby reducing stalls caused by contention between the CPU and the GPDMA controller. CAUTION If level three Code Read Protection (CRP3) is selected, no future factory testing can be performed on the device.

This matrix connects the instruction (I-code) and data (D-code) CPU buses of the ARM Cortex-M3 to the flash memory, the main (32 kB) static RAM, and the Boot ROM. The GPDMA can also access all of these memories. The peripheral DMA controllers, Ethernet, and USB can access all SRAM blocks. Additionally, the matrix connects the CPU system bus and all of the DMA controllers to the various peripheral functions. 8.30.6 External interrupt inputs The LPC17xx include up to 46 edge sensitive interrupt inputs combined with up to four level sensitive external interrupt inputs as selectable pin functions. The external interrupt inputs can optionally be used to wake up the processor from Power-down mode. 8.30.7 Memory mapping control The Cortex-M3 incorporates a mechanism that allows remapping the interrupt vector table to alternate locations in the memory map. This is controlled via the Vector Table Offset Register contained in the NVIC. The vector table may be located anywhere within the bottom 1 GB of Cortex-M3 address space. The vector table must be located on a 128 word (512 byte) boundary because the NVIC on the LPC17xx is configured for 128 total interrupts. 8.31 Emulation and debugging Debug and trace functions are integrated into the ARM Cortex-M3. Serial wire debug and trace functions are supported in addition to a standard JTAG debug and parallel trace functions. The ARM Cortex-M3 is configured to support up to eight breakpoints and four watch points.

The I/O power dissipation of the I/O pins is often small and many times can be negligible. However it can be significant in some applications. Table 7.

[2] Parameters are valid over operating temperature range unless otherwise specified. [3] A device must internally provide a hold time of at least 300 ns for the SDA signal (with respect to the VIH(min) of the SCL signal) to bridge the undefined region of the falling edge of SCL. [4] Cb = total capacitance of one bus line in pF. [5] The maximum tf for the SDA and SCL bus lines is specified at 300 ns. The maximum fall time for the SDA output stage tf is specified at 250 ns. This allows series protection resistors to be connected in between the SDA and the SCL pins and the SDA/SCL bus lines without exceeding the maximum specified tf. [6] In Fast-mode Plus, fall time is specified the same for both output stage and bus timing. If series resistors are used, designers should allow for this when considering bus timing. [7] tHD;DAT is the data hold time that is measured from the falling edge of SCL; applies to data in transmission and the acknowledge. [8] The maximum tHD;DAT could be 3.45 s and 0.9 s for Standard-mode and Fast-mode but must be less than the maximum of tVD;DAT or tVD;ACK by a transition time (see the I2C-bus specification UM10204). This maximum must only be met if the device does not stretch the LOW period (tLOW) of the SCL signal. If the clock stretches the SCL, the data must be valid by the set-up time before it releases the clock. [9] tSU;DAT is the data set-up time that is measured with respect to the rising edge of SCL; applies to data in transmission and the acknowledge. [10] A Fast-mode I2C-bus device can be used in a Standard-mode I2C-bus system but the requirement tSU;DAT = 250 ns must then be met. This will automatically be the case if the device does not stretch the LOW period of the SCL signal. If such a device does stretch the LOW period of the SCL signal, it must output the next data bit to the SDA line tr(max) + tSU;DAT = 1000 + 250 = 1250 ns (according to the Standard-mode I2C-bus specification) before the SCL line is released. Also the acknowledge timing must meet this set-up time. Table 14.

Application information 15.1 Suggested USB interface solutions Remark: The USB controller is available as a device/Host/OTG controller on parts LPC1769/68/66/65 and as device-only controller on part LPC1764. If the LPC1769/68/67/66/65/64/63 VDD is always greater than 0 V while VBUS = 5 V, the VBUS pin can be connected directly to the VBUS pin on the USB connector. This applies to bus powered devices where the USB cable supplies the system power. For systems where VDD can be 0 V and VBUS is directly applied to the VBUS pin, precautions must be taken to reduce the voltage to below 3.6 V. The maximum allowable voltage on the VBUS pin is 3.6 V. One method is to use a voltage divider to connect the VBUS pin to the VBUS on the USB connector. The voltage divider ratio should be such that the VBUS pin will be greater than 0.7VDD to indicate a logic HIGH while below the 3.6 V allowable maximum voltage. Use the following operating conditions: VBUSmax = 5.25 V VDD = 3.6 V The voltage divider would need to provide a reduction of 3.6 V/5.25 V or ~0.686 V. Fig 29.

If the oscillator is driven by a clock in slave mode, it is recommended that the input be coupled through a capacitor with Ci = 100 pF. To limit the input voltage to the specified range, choose an additional capacitor to ground Cg which attenuates the input voltage by a factor Ci/(Ci + Cg). In slave mode, a minimum of 200 mV(RMS) is needed. In slave mode the input clock signal should be coupled by means of a capacitor of 100 pF (Figure 35), with an amplitude between 200 mV(RMS) and 1000 mV(RMS). This corresponds to a square wave signal with a signal swing of between 280 mV and 1.4 V. The XTALOUT pin in this configuration can be left unconnected. External components and models used in oscillation mode are shown in Figure 36 and in Table 23 and Table 24. Since the feedback resistance is integrated on chip, only a crystal and the capacitances CX1 and CX2 need to be connected externally in case of fundamental mode oscillation (the fundamental frequency is represented by L, CL and RS). Capacitance CP in Figure 36 represents the parallel package capacitance and should not be larger than 7 pF. Parameters FOSC, CL, RS and CP are supplied by the crystal manufacturer. Fig 34.

Also parasitics should stay as small as possible.

General description The PCF8574/74A provides general-purpose remote I/O expansion via the two-wire bidirectional I2C-bus (serial clock (SCL), serial data (SDA)). The devices consist of eight quasi-bidirectional ports, 100 kHz I2C-bus interface, three hardware address inputs and interrupt output operating between 2.5 V and 6 V. The quasi-bidirectional port can be independently assigned as an input to monitor interrupt status or keypads, or as an output to activate indicator devices such as LEDs. System master can read from the input port or write to the output port through a single register. The low current consumption of 2.5 A (typical, static) is great for mobile applications and the latched output ports directly drive LEDs. The PCF8574 and PCF8574A are identical, except for the different fixed portion of the slave address. The three hardware address pins allow eight of each device to be on the same I2C-bus, so there can be up to 16 of these I/O expanders PCF8574/74A together on the same I2C-bus, supporting up to 128 I/Os (for example, 128 LEDs). The active LOW open-drain interrupt output (INT) can be connected to the interrupt logic of the microcontroller and is activated when any input state differs from its corresponding input port register state. It is used to indicate to the microcontroller that an input state has changed and the device needs to be interrogated without the microcontroller continuously polling the input register via the I2C-bus. The internal Power-On Reset (POR) initializes the I/Os as inputs with a weak internal pull-up 100 A current source. 2.

Functional description Refer to Figure 1 “Block diagram”. 7.1 Device address Following a START condition, the bus master must send the address of the slave it is accessing and the operation it wants to perform (read or write). The address format of the PCF8574/74A is shown in Figure 6. Slave address pins A2, A1 and A0 are held HIGH or LOW to choose one of eight slave addresses. To conserve power, no internal pull-up resistors are incorporated on A2, A1 or A0, so they must be externally held HIGH or LOW. The address pins (A2, A1, A0) can connect to VDD or VSS directly or through resistors. The last bit of the first byte defines the operation to be performed. When set to logic 1 a read is selected, while a logic 0 selects a write operation (write operation is shown in Figure 6). 7.1.1 Address maps The PCF8574 and PCF8574A are functionally the same, but have a different fixed portion (A6 to A3) of the slave address. This allows eight of the PCF8574 and eight of the PCF8574A to be on the same I2C-bus without address conflict. a. PCF8574 b. PCF8574A Fig 6.

I/O programming 8.1 Quasi-bidirectional I/Os A quasi-bidirectional I/O is an input or output port without using a direction control register. Whenever the master reads the register, the value returned to master depends on the actual voltage or status of the pin. At power on, all the ports are HIGH with a weak 100 A internal pull-up to VDD, but can be driven LOW by an internal transistor, or an external signal. The I/O ports are entirely independent of each other, but each I/O octal is controlled by the same read or write data byte. Advantages of the quasi-bidirectional I/O over totem pole I/O include: • Better for driving LEDs since the p-channel (transistor to VDD) is small, which saves die size and therefore cost. LED drive only requires an internal transistor to ground, while the LED is connected to VDD through a current-limiting resistor. Totem pole I/O have both n-channel and p-channel transistors, which allow solid HIGH and LOW output levels without a pull-up resistor — good for logic levels. • Simpler architecture — only a single register and the I/O can be both input and output at the same time. Totem pole I/O have a direction register that specifies the port pin direction and it is always in that configuration unless the direction is explicitly changed. • Does not require a command byte. The simplicity of one register (no need for the pointer register or, technically, the command byte) is an advantage in some embedded systems where every byte counts because of memory or bandwidth limitations.

Product data sheet Rev. 5 — 27 May 2013 7 of 33 NXP Semiconductors PCF8574; PCF8574A Remote 8-bit I/O expander for I2C-bus with interrupt There is only one register to control four possibilities of the port pin: Input HIGH, input LOW, output HIGH, or output LOW. Input HIGH: The master needs to write 1 to the register to set the port as an input mode if the device is not in the default power-on condition. The master reads the register to check the input status. If the external source pulls the port pin up to VDD or drives logic 1, then the master will read the value of 1. Input LOW: The master needs to write 1 to the register to set the port to input mode if the device is not in the default power-on condition. The master reads the register to check the input status. If the external source pulls the port pin down to VSS or drives logic 0, which sinks the weak 100 A current source, then the master will read the value of 0. Output HIGH: The master writes 1 to the register. There is an additional ‘accelerator’ or strong pull-up current when the master sets the port HIGH. The additional strong pull-up is only active during the HIGH time of the acknowledge clock cycle. This accelerator current helps the port’s 100 A current source make a faster rising edge into a heavily loaded output, but only at the start of the acknowledge clock cycle to avoid bus contention if an external signal is pulling the port LOW to VSS/driving the port with logic 0 at the same time. After the half clock cycle there is only the 100 A current source to hold the port HIGH. Output LOW: The master writes 0 to the register. There is a strong current sink transistor that holds the port pin LOW. A large current may flow into the port, which could potentially damage the part if the master writes a 0 to the register and an external source is pulling the port HIGH at the same time. Fig 7.

The PCF8574/74A acknowledges and the master then sends the data byte for P7 to P0 to the port register. As the clock line goes HIGH, the 8-bit data is presented on the port lines after it has been acknowledged by the PCF8574/74A. If a LOW is written, the strong pull-down turns on and stays on. If a HIGH is written, the strong pull-up turns on for 1⁄2 of the clock cycle, then the line is held HIGH by the weak current source. The master can then send a STOP or ReSTART condition or continue sending data. The number of data bytes that can be sent successively is not limited and the previous data is overwritten every time a data byte has been sent and acknowledged. Ensure a logic 1 is written for any port that is being used as an input to ensure the strong external pull-down is turned off. Simple code WRITE mode:

device and sets the last bit of the address byte to logic 1 (address byte read). The slave
will acknowledge and then send the data byte to the master. The master will NACK and
then send the STOP condition or ACK and read the input register again.
The read of any pin being used as an output will indicate HIGH or LOW depending on the
actual state of the pin.
If the data on the input port changes faster than the master can read, this data may be
lost. The DATA 2 and DATA3 are lost because these data did not meet the setup time and
hold time (see Figure 9).
Simple code for Read mode:
Remark: Bold type = generated by slave device.
8.4 Power-on reset
When power is applied to VDD, an internal Power-On Reset (POR) holds the
PCF8574/74A in a reset condition until VDD has reached VPOR. At that point, the reset
condition is released and the PCF8574/74A registers and I2C-bus/SMBus state machine
will initialize to their default states of all I/Os to inputs with weak current source to VDD.
Thereafter VDD must be lowered below VPOR and back up to the operation voltage for
power-on reset cycle.
A LOW-to-HIGH transition of SDA while SCL is HIGH is defined as the STOP condition (P). Transfer of data can be stopped at
any moment by a STOP condition. When this occurs, data present at the last acknowledge phase is valid (output mode). Input
data is lost.

8.5 Interrupt output (INT)
The PCF8574/74A provides an open-drain output (INT) which can be fed to a
corresponding input of the microcontroller (see Figure 10). As soon as a port input is
changed, the INT will be active (LOW) and notify the microcontroller.
An interrupt is generated at any rising or falling edge of the port inputs. After time tv(Q), the
signal INT is valid.
The interrupt will reset to HIGH when data on the port is changed to the original setting or
data is read or written by the master.
In the Write mode, the interrupt may be reset (HIGH) on the rising edge of the
acknowledge bit of the address byte and also on the rising edge of the write to port pulse.
The interrupt will always be reset (HIGH) on the falling edge of the write to port pulse (see
Figure 8).
The interrupt is reset (HIGH) in the Read mode on the rising edge of the read from port
pulse (see Figure 9).
During the interrupt reset, any I/O change close to the read or write pulse may not
generate an interrupt, or the interrupt will have a very short pulse. After the interrupt is
reset, any change in I/Os will be detected and transmitted as an INT.
At power-on reset all ports are in Input mode and the initial state of the ports is HIGH,
therefore, for any port pin that is pulled LOW or driven LOW by external source, the
interrupt output will be active (output LOW).

Remote 8-bit I/O expander for I2C-bus with interrupt
9. Characteristics of the I2C-bus
The I2C-bus is for 2-way, 2-wire communication between different ICs or modules. The
two wires are a serial data line (SDA) and a serial clock line (SCL). Both lines must be
connected to a positive supply via a pull-up resistor when connected to the output stages
of a device. Data transfer may be initiated only when the bus is not busy.
9.1 Bit transfer
One data bit is transferred during each clock pulse. The data on the SDA line must remain
stable during the HIGH period of the clock pulse as changes in the data line at this time
will be interpreted as control signals (see Figure 11).
9.1.1 START and STOP conditions
Both data and clock lines remain HIGH when the bus is not busy. A HIGH-to-LOW
transition of the data line while the clock is HIGH is defined as the START condition (S). A
LOW-to-HIGH transition of the data line while the clock is HIGH is defined as the STOP
condition (P) (see Figure 12).
9.2 System configuration
A device generating a message is a ‘transmitter’; a device receiving is the ‘receiver’. The
device that controls the message is the ‘master’ and the devices which are controlled by
the master are the ‘slaves’ (see Figure 13).

9.3 Acknowledge
The number of data bytes transferred between the START and the STOP conditions from
transmitter to receiver is not limited. Each byte of eight bits is followed by one
acknowledge bit (see Figure 14). The acknowledge bit is an active LOW level (generated
by the receiving device) that indicates to the transmitter that the data transfer was
successful.
A slave receiver which is addressed must generate an acknowledge after the reception of
each byte. Also a master must generate an acknowledge after the reception of each byte
that has been clocked out of the slave transmitter. The device that wants to issue an
acknowledge bit has to pull down the SDA line during the acknowledge clock pulse, so
that the SDA line is stable LOW during the HIGH period of the acknowledge bit related
clock pulse; set-up and hold times must be taken into account.
A master receiver must signal an end of data to the transmitter by not generating an
acknowledge on the last byte that has been clocked out of the slave. In this event, the
transmitter must leave the data line HIGH to enable the master to generate a STOP
condition.

Remote 8-bit I/O expander for I2C-bus with interrupt
10. Application design-in information
10.1 Bidirectional I/O expander applications
In the 8-bit I/O expander application shown in Figure 15, P0 and P1 are inputs, and
P2 to P7 are outputs. When used in this configuration, during a write, the input (P0 and
P1) must be written as HIGH so the external devices fully control the input ports.
The desired HIGH or LOW logic levels may be written to the ports used as outputs (P2 to
P7). If 10 A internal output HIGH is not enough current source, the port needs external
pull-up resistor. During a read, the logic levels of the external devices driving the input
ports (P0 and P1) and the previous written logic level to the output ports (P2 to P7) will be
read.
The GPIO also has an interrupt line (INT) that can be connected to the interrupt logic of
the microcontroller. By sending an interrupt signal on this line, the remote I/O informs the
microprocessor that there has been a change of data on its ports without having to
communicate via the I2C-bus.
10.2 How to read and write to I/O expander (example)
In the application example of PCF8574 shown in Figure 15, the microcontroller wants to
control the P3 switch ON and the P7 LED ON when the temperature sensor P0 changes.
1. When the system power on:
Core Processor needs to issue an initial command to set P0 and P1 as inputs and
P[7:2] as outputs with value 1010 00 (LED off, MP3 off, camera on, audio off,
switch off and latch off).
2. Operation:
When the temperature changes above the threshold, the temperature sensor signal
will toggle from HIGH to LOW. The INT will be activated and notifies the ‘core
processor’ that there have been changes on the input pins. Read the input register.
If P0 = 0 (temperature sensor has changed), then turn on LED and turn on switch.
3. Software code:
//System Power on
// write to PCF8574 with data 1010 0011b to set P[7:2] outputs and P[1:0] inputs
//Initial setting for PCF9574

10.3 High current-drive load applications
The GPIO has a minimum guaranteed sinking current of 10 mA per bit at 5 V. In
applications requiring additional drive, two port pins may be connected together to sink up
to 20 mA current. Both bits must then always be turned on or off together. Up to five pins
can be connected together to drive 80 mA, which is the device recommended total limit.
Each pin needs its own limiting resistor as shown in Figure 16 to prevent damage to the
device should all ports not be turned on at the same time.
10.4 Migration path
NXP offers newer, more capable drop-in replacements for the PCF8574/74A in newer
space-saving packages.
PCA9670 replaces the interrupt output of the PCA9674 with hardware reset input to retain
the maximum number of addresses and the PCA9672 replaces address A2 of the
PCA9674 with hardware reset input to retain the interrupt but limit the number of
addresses.

All input and output pins are protected against ElectroStatic Discharge (ESD) under
normal handling. When handling ensure that the appropriate precautions are taken as
described in JESD625-A or equivalent standards.
17. Soldering of SMD packages
This text provides a very brief insight into a complex technology. A more in-depth account
of soldering ICs can be found in Application Note AN10365 “Surface mount reflow
soldering description”.
17.1 Introduction to soldering
Soldering is one of the most common methods through which packages are attached to
Printed Circuit Boards (PCBs), to form electrical circuits. The soldered joint provides both
the mechanical and the electrical connection. There is no single soldering method that is
ideal for all IC packages. Wave soldering is often preferred when through-hole and
Surface Mount Devices (SMDs) are mixed on one printed wiring board; however, it is not
suitable for fine pitch SMDs. Reflow soldering is ideal for the small pitches and high
densities that come with increased miniaturization.
17.2 Wave and reflow soldering
Wave soldering is a joining technology in which the joints are made by solder coming from
a standing wave of liquid solder. The wave soldering process is suitable for the following:
• Through-hole components
• Leaded or leadless SMDs, which are glued to the surface of the printed circuit board
Not all SMDs can be wave soldered. Packages with solder balls, and some leadless
packages which have solder lands underneath the body, cannot be wave soldered. Also,
leaded SMDs with leads having a pitch smaller than ~0.6 mm cannot be wave soldered,
due to an increased probability of bridging.
The reflow soldering process involves applying solder paste to a board, followed by
component placement and exposure to a temperature profile. Leaded packages,
packages with solder balls, and leadless packages are all reflow solderable.
Key characteristics in both wave and reflow soldering are:
• Board specifications, including the board finish, solder masks and vias
• Package footprints, including solder thieves and orientation
• The moisture sensitivity level of the packages
• Package placement
• Inspection and repair
• Lead-free soldering versus SnPb soldering

• Process issues, such as application of adhesive and flux, clinching of leads, board
transport, the solder wave parameters, and the time during which components are
exposed to the wave
• Solder bath specifications, including temperature and impurities
17.4 Reflow soldering
Key characteristics in reflow soldering are:
• Lead-free versus SnPb soldering; note that a lead-free reflow process usually leads to
higher minimum peak temperatures (see Figure 21) than a SnPb process, thus
reducing the process window
• Solder paste printing issues including smearing, release, and adjusting the process
window for a mix of large and small components on one board
• Reflow temperature profile; this profile includes preheat, reflow (in which the board is
heated to the peak temperature) and cooling down. It is imperative that the peak
temperature is high enough for the solder to make reliable solder joints (a solder paste
characteristic). In addition, the peak temperature must be low enough that the
packages and/or boards are not damaged. The peak temperature of the package
depends on package thickness and volume and is classified in accordance with
Table 11 and 12
Moisture sensitivity precautions, as indicated on the packing, must be respected at all
times.
Studies have shown that small packages reach higher temperatures during reflow
soldering, see Figure 21.

18. Soldering of through-hole mount packages
18.1 Introduction to soldering through-hole mount packages
This text gives a very brief insight into wave, dip and manual soldering.
Wave soldering is the preferred method for mounting of through-hole mount IC packages
on a printed-circuit board.
18.2 Soldering by dipping or by solder wave
Driven by legislation and environmental forces the worldwide use of lead-free solder
pastes is increasing. Typical dwell time of the leads in the wave ranges from
3 seconds to 4 seconds at 250 C or 265 C, depending on solder material applied, SnPb
or Pb-free respectively.
The total contact time of successive solder waves must not exceed 5 seconds.
The device may be mounted up to the seating plane, but the temperature of the plastic
body must not exceed the specified maximum storage temperature (Tstg(max)). If the
printed-circuit board has been pre-heated, forced cooling may be necessary immediately
after soldering to keep the temperature within the permissible limit.
18.3 Manual soldering
Apply the soldering iron (24 V or less) to the lead(s) of the package, either below the
seating plane or not more than 2 mm above it. If the temperature of the soldering iron bit is
less than 300 C it may remain in contact for up to 10 seconds. If the bit temperature is
between 300 C and 400 C, contact may be up to 5 seconds.

points.
System tick timer.
System:
Multilayer AHB matrix interconnect provides a separate bus for each AHB master.
AHB masters include the CPU, and General Purpose DMA controller. This
interconnect provides communication with no arbitration delays unless two masters
attempt to access the same slave at the same time.
Split APB bus allows for higher throughput with fewer stalls between the CPU and
DMA. A single level of write buffering allows the CPU to continue without waiting for
completion of APB writes if the APB was not already busy.
Embedded Trace Macrocell (ETM) module supports real-time trace.
Boundary scan for simplified board testing.
Memory:
512 kB on-chip flash program memory with In-System Programming (ISP) and
In-Application Programming (IAP) capabilities. The combination of an enhanced
flash memory accelerator and location of the flash memory on the CPU local
code/data bus provides high code performance from flash.
Up to 96 kB on-chip SRAM includes:
64 kB of main SRAM on the CPU with local code/data bus for high-performance
CPU access.
Two 16 kB peripheral SRAM blocks with separate access paths for higher
throughput. These SRAM blocks may be used for DMA memory as well as for
general purpose instruction and data storage.
Up to 4032 byte on-chip EEPROM.
LCD controller, supporting both Super-Twisted Nematic (STN) and Thin-Film
Transistors (TFT) displays.
Dedicated DMA controller.
Selectable display resolution (up to 1024 768 pixels).
Supports up to 24-bit true-color mode.
External Memory Controller (EMC) provides support for asynchronous static memory
devices such as RAM, ROM and flash, as well as dynamic memories such as single
data rate SDRAM.
Eight channel General Purpose DMA controller (GPDMA) on the AHB multilayer
matrix that can be used with the SSP, I2S, UART, CRC engine, Analog-to-Digital and
Digital-to-Analog converter peripherals, timer match signals, GPIO, and for
memory-to-memory transfers.
Serial interfaces:
Quad SPI Flash Interface (SPIFI) with four lanes and up to 40 MB per second.
Ethernet MAC with MII/RMII interface and associated DMA controller. These
functions reside on an independent AHB.
USB 2.0 full-speed dual port device/host/OTG controller with on-chip PHY and
associated DMA controller.
Five UARTs with fractional baud rate generation, internal FIFO, DMA support, and
RS-485/EIA-485 support. One UART (UART1) has full modem control I/O, and one
UART (USART4) supports IrDA, synchronous mode, and a smart card mode
conforming to ISO7816-3.

NXP Semiconductors LPC408x/7x
32-bit ARM Cortex-M4 microcontroller
Three SSP controllers with FIFO and multi-protocol capabilities. The SSP
interfaces can be used with the GPDMA controller.
Three enhanced I2C-bus interfaces, one with a true open-drain output supporting
the full I2C-bus specification and Fast-mode Plus with data rates of 1 Mbit/s, two
with standard port pins. Enhancements include multiple address recognition and
monitor mode.
I2S (Inter-IC Sound) interface for digital audio input or output. It can be used with
the GPDMA.
CAN controller with two channels.
Digital peripherals:
SD/MMC memory card interface.
Up to 165 General Purpose I/O (GPIO) pins depending on the packaging, with
configurable pull-up/down resistors, open-drain mode, and repeater mode. All
GPIOs are located on an AHB bus for fast access and support Cortex-M4
bit-banding. GPIOs can be accessed by the General Purpose DMA Controller. Any
pin of ports 0 and 2 can be used to generate an interrupt.
Two external interrupt inputs configurable as edge/level sensitive. All pins on port 0
and port 2 can be used as edge sensitive interrupt sources.
Four general purpose timers/counters, with a total of eight capture inputs and ten
compare outputs. Each timer block has an external count input. Specific timer
events can be selected to generate DMA requests.
Quadrature encoder interface that can monitor one external quadrature encoder.
Two standard PWM/timer blocks with external count input option.
One motor control PWM with support for three-phase motor control.
Real-Time Clock (RTC) with a separate power domain. The RTC is clocked by a
dedicated RTC oscillator. The RTC block includes 20 bytes of battery-powered
backup registers, allowing system status to be stored when the rest of the chip is
powered off. Battery power can be supplied from a standard 3 V lithium button cell.
The RTC will continue working when the battery voltage drops to as low as 2.1 V.
An RTC interrupt can wake up the CPU from any reduced power mode.
Event Recorder that can capture the clock value when an event occurs on any of
three inputs. The event identification and the time it occurred are stored in
registers. The Event Recorder is located in the RTC power domain and can
therefore operate as long as there is RTC power.
Windowed Watchdog Timer (WWDT). Windowed operation, dedicated internal
oscillator, watchdog warning interrupt, and safety features.
CRC Engine block can calculate a CRC on supplied data using one of three
standard polynomials. The CRC engine can be used in conjunction with the DMA
controller to generate a CRC without CPU involvement in the data transfer.
Analog peripherals:
12-bit Analog-to-Digital Converter (ADC) with input multiplexing among eight pins,
conversion rates up to 400 kHz, and multiple result registers. The 12-bit ADC can
be used with the GPDMA controller.
10-bit Digital-to-Analog Converter (DAC) with dedicated conversion timer and DMA
support.
Two analog comparators.

used as a system clock.
An on-chip PLL allows CPU operation up to the maximum CPU rate without the
need for a high-frequency crystal. May be run from the main oscillator or the
internal RC oscillator.
A second, dedicated PLL may be used for USB interface in order to allow added
flexibility for the Main PLL settings.

6.2 Pin description
I/O pins on the LPC408x/7x are 5 V tolerant and have input hysteresis unless otherwise
indicated in the table below. Crystal pins, power pins, and reference voltage pins are not
5 V tolerant. In addition, when pins are selected to be ADC inputs, they are no longer 5 V
tolerant and the input voltage must be limited to the voltage at the ADC positive reference
pin (VREFP).
All port pins Pn[m] are multiplexed, and the multiplexed functions appear in Table 3 in the
order defined by the FUNC bits of the corresponding IOCON register up to the highest
used function number. Each port pin can support up to eight multiplexed functions.
IOCON register FUNC values which are reserved are noted as “R” in the pin configuration
table.

NXP Semiconductors LPC408x/7x
32-bit ARM Cortex-M4 microcontroller
7. Functional description
7.1 Architectural overview
The ARM Cortex-M4 includes three AHB-Lite buses: the system bus, the I-code bus, and
the D-code bus. The I-code and D-code core buses are faster than the system bus and
are used similarly to Tightly Coupled Memory (TCM) interfaces: one bus dedicated for
instruction fetch (I-code) and one bus for data access (D-code). The use of two core
buses allows for simultaneous operations if concurrent operations target different devices.
The LPC408x/7x use a multi-layer AHB matrix to connect the ARM Cortex-M4 buses and
other bus masters to peripherals in a flexible manner that optimizes performance by
allowing peripherals that are on different slaves ports of the matrix to be accessed
simultaneously by different bus masters.
7.2 ARM Cortex-M4 processor
The ARM Cortex-M4 processor is running at frequencies of up to 120 MHz. The processor
executes the Thumb-2 instruction set for optimal performance and code size, including
hardware division, single-cycle multiply, and bit-field manipulation. A Memory Protection
Unit (MPU) supporting eight regions is included.
7.3 ARM Cortex-M4 Floating Point Unit (FPU)
Remark: The FPU is available on parts LP4088/78/76.
The FPU supports single-precision floating-point computation functionality in compliance
with the ANSI/IEEE Standard 754-2008. The FPU provides add, subtract, multiply, divide,
multiply and accumulate, and square root operations. It also performs a variety of
conversions between fixed-point, floating-point, and integer data formats.
7.4 On-chip flash program memory
The LPC408x/7x contain up to 512 kB of on-chip flash program memory. A new two-port
flash accelerator maximizes performance for use with the two fast AHB-Lite buses.
7.5 EEPROM
The LPC408x/7x contains up to 4032 byte of on-chip byte-erasable and
byte-programmable EEPROM data memory.
7.6 On-chip SRAM
The LPC408x/7x contain a total of up to 96 kB on-chip SRAM data memory. This includes
64 kB main SRAM, accessible by the CPU and DMA controller on a higher-speed bus,
and up to two additional 16 kB peripheral SRAM blocks situated on a separate slave port
on the AHB multilayer matrix.
This architecture allows CPU and DMA accesses to be spread over three separate RAMs
that can be accessed simultaneously.

7.7 Memory Protection Unit (MPU)
The LPC408x/7x have a Memory Protection Unit (MPU) which can be used to improve the
reliability of an embedded system by protecting critical data within the user application.
The MPU allows separating processing tasks by disallowing access to each other's data,
disabling access to memory regions, allowing memory regions to be defined as read-only
and detecting unexpected memory accesses that could potentially break the system.
The MPU separates the memory into distinct regions and implements protection by
preventing disallowed accesses. The MPU supports up to eight regions each of which can
be divided into eight subregions. Accesses to memory locations that are not defined in the
MPU regions, or not permitted by the region setting, will cause the Memory Management
Fault exception to take place.

7.12 General purpose DMA controller
The GPDMA is an AMBA AHB compliant peripheral allowing selected peripherals to have
DMA support.
The GPDMA enables peripheral-to-memory, memory-to-peripheral,
peripheral-to-peripheral, and memory-to-memory transactions. The source and
destination areas can each be either a memory region or a peripheral and can be
accessed through the AHB master. The GPDMA controller allows data transfers between
the various on-chip SRAM areas and supports the SD/MMC card interface, all SSPs, the
I2S, all UARTs, the A/D Converter, and the D/A Converter peripherals. DMA can also be
triggered by selected timer match conditions. Memory-to-memory transfers and transfers
to or from GPIO are supported.
7.12.1 Features
• Eight DMA channels. Each channel can support an unidirectional transfer.
• 16 DMA request lines.
• Single DMA and burst DMA request signals. Each peripheral connected to the DMA
Controller can assert either a burst DMA request or a single DMA request. The DMA
burst size is set by programming the DMA Controller.
• Memory-to-memory, memory-to-peripheral, peripheral-to-memory, and
peripheral-to-peripheral transfers are supported.
• Scatter or gather DMA is supported through the use of linked lists. This means that
the source and destination areas do not have to occupy contiguous areas of memory.
• Hardware DMA channel priority.
• AHB slave DMA programming interface. The DMA Controller is programmed by
writing to the DMA control registers over the AHB slave interface.
• One AHB bus master for transferring data. The interface transfers data when a DMA
request goes active.
• 32-bit AHB master bus width.
• Incrementing or non-incrementing addressing for source and destination.
• Programmable DMA burst size. The DMA burst size can be programmed to more
efficiently transfer data.
• Internal four-word FIFO per channel.
• Supports 8, 16, and 32-bit wide transactions.
• Big-endian and little-endian support. The DMA Controller defaults to little-endian
mode on reset.
• An interrupt to the processor can be generated on a DMA completion or when a DMA
error has occurred.
• Raw interrupt status. The DMA error and DMA count raw interrupt status can be read
prior to masking.
7.13 CRC engine
The Cyclic Redundancy Check (CRC) generator with programmable polynomial settings
supports several CRC standards commonly used. To save system power and bus
bandwidth, the CRC engine supports DMA transfers.

– 32-bit write: 4-cycle operation (8-bit x 4-cycle)
7.14 LCD controller
Remark: The LCD controller is available on parts LPC4088.
The LCD controller provides all of the necessary control signals to interface directly to a
variety of color and monochrome LCD panels. Both STN (single and dual panel) and TFT
panels can be operated. The display resolution is selectable and can be up to 1024 768
pixels. Several color modes are provided, up to a 24-bit true-color non-palettized mode.
An on-chip 512-byte color palette allows reducing bus utilization (i.e. memory size of the
displayed data) while still supporting a large number of colors.
The LCD interface includes its own DMA controller to allow it to operate independently of
the CPU and other system functions. A built-in FIFO acts as a buffer for display data,
providing flexibility for system timing. Hardware cursor support can further reduce the
amount of CPU time needed to operate the display.
7.14.1 Features
• AHB master interface to access frame buffer.
• Setup and control via a separate AHB slave interface.
• Dual 16-deep programmable 64-bit wide FIFOs for buffering incoming display data.
• Supports single and dual-panel monochrome Super Twisted Nematic (STN) displays
with 4-bit or 8-bit interfaces.
• Supports single and dual-panel color STN displays.
• Supports Thin Film Transistor (TFT) color displays.
• Programmable display resolution including, but not limited to: 320 200, 320 240,
640 200, 640 240, 640 480, 800 600, and 1024 768.

operation on a SPI, 4-wire SSI, or Microwire bus. It can interact with multiple masters and
slaves on the bus. Only a single master and a single slave can communicate on the bus
during a given data transfer. The SSP supports full duplex transfers, with frames of 4 bits
to 16 bits of data flowing from the master to the slave and from the slave to the master. In
practice, often only one of these data flows carries meaningful data.

(SCL) and a Serial Data Line (SDA). Each device is recognized by a unique address and
can operate as either a receiver-only device (e.g., an LCD driver) or a transmitter with the
capability to both receive and send information (such as memory). Transmitters and/or
receivers can operate in either master or slave mode, depending on whether the chip has
to initiate a data transfer or is only addressed. The I2C is a multi-master bus and can be
controlled by more than one bus master connected to it.

communication interface for digital audio applications.
The I2S-bus specification defines a 3-wire serial bus using one data line, one clock line,
and one word select signal. The basic I2S connection has one master, which is always the
master, and one slave. The I2S interface on the LPC408x/7x provides a separate transmit
and receive channel, each of which can operate as either a master or a slave.
7.26.1 Features
• The interface has separate input/output channels each of which can operate in master
or slave mode.
• Capable of handling 8-bit, 16-bit, and 32-bit word sizes.

Product data sheet Rev. 3 — 1 May 2014 68 of 141
NXP Semiconductors LPC408x/7x
32-bit ARM Cortex-M4 microcontroller
The Controller Area Network (CAN) is a serial communications protocol which efficiently
supports distributed real-time control with a very high level of security. Its domain of
application ranges from high-speed networks to low cost multiplex wiring.
The CAN block is intended to support multiple CAN buses simultaneously, allowing the
device to be used as a gateway, switch, or router between two of CAN buses in industrial
or automotive applications.
Each CAN controller has a register structure similar to the NXP SJA1000 and the PeliCAN
Library block, but the 8-bit registers of those devices have been combined in 32-bit words
to allow simultaneous access in the ARM environment. The main operational difference is
that the recognition of received Identifiers, known in CAN terminology as Acceptance
Filtering, has been removed from the CAN controllers and centralized in a global
Acceptance Filter.
7.27.1 Features
• Two CAN controllers and buses.
• Data rates to 1 Mbit/s on each bus.
• 32-bit register and RAM access.
• Compatible with CAN specification 2.0B, ISO 11898-1.

Standard Identifiers.
• FullCAN messages can generate interrupts.
7.28 General purpose 32-bit timers/external event counters
The LPC408x/7x include four 32-bit timer/counters.
The timer/counter is designed to count cycles of the system derived clock or an
externally-supplied clock. It can optionally generate interrupts, generate timed DMA
requests, or perform other actions at specified timer values, based on four match
registers. Each timer/counter also includes two capture inputs to trap the timer value when
an input signal transitions, optionally generating an interrupt.
7.28.1 Features
• A 32-bit timer/counter with a programmable 32-bit prescaler.
• Counter or timer operation.
• Two 32-bit capture channels per timer, that can take a snapshot of the timer value
when an input signal transitions. A capture event may also generate an interrupt.
• Four 32-bit match registers that allow:
– Continuous operation with optional interrupt generation on match.
– Stop timer on match with optional interrupt generation.
– Reset timer on match with optional interrupt generation.
• Up to four external outputs corresponding to match registers, with the following
capabilities:

NXP Semiconductors LPC408x/7x
32-bit ARM Cortex-M4 microcontroller
– Set LOW on match.
– Set HIGH on match.
– Toggle on match.
– Do nothing on match.
• Up to two match registers can be used to generate timed DMA requests.
7.29 Pulse Width Modulator (PWM)
The LPC408x/7x contain two standard PWMs.
The PWM is based on the standard Timer block and inherits all of its features, although
only the PWM function is pinned out on the LPC408x/7x. The Timer is designed to count
cycles of the system derived clock and optionally switch pins, generate interrupts or
perform other actions when specified timer values occur, based on seven match registers.
The PWM function is in addition to these features, and is based on match register events.
The ability to separately control rising and falling edge locations allows the PWM to be
used for more applications. For instance, multi-phase motor control typically requires
three non-overlapping PWM outputs with individual control of all three pulse widths and
positions.
Two match registers can be used to provide a single edge controlled PWM output. One
match register (PWMMR0) controls the PWM cycle rate, by resetting the count upon
match. The other match register controls the PWM edge position. Additional single edge
controlled PWM outputs require only one match register each, since the repetition rate is
the same for all PWM outputs. Multiple single edge controlled PWM outputs will all have a
rising edge at the beginning of each PWM cycle, when an PWMMR0 match occurs.
Three match registers can be used to provide a PWM output with both edges controlled.
Again, the PWMMR0 match register controls the PWM cycle rate. The other match
registers control the two PWM edge positions. Additional double edge controlled PWM
outputs require only two match registers each, since the repetition rate is the same for all
PWM outputs.
With double edge controlled PWM outputs, specific match registers control the rising and
falling edge of the output. This allows both positive going PWM pulses (when the rising
edge occurs prior to the falling edge), and negative going PWM pulses (when the falling
edge occurs prior to the rising edge).
7.29.1 Features
• LPC408x/7x has two PWM blocks with Counter or Timer operation (may use the
peripheral clock or one of the capture inputs as the clock source).
• Seven match registers allow up to 6 single edge controlled or 3 double edge
controlled PWM outputs, or a mix of both types. The match registers also allow:
– Continuous operation with optional interrupt generation on match.
– Stop timer on match with optional interrupt generation.
– Reset timer on match with optional interrupt generation.

Product data sheet Rev. 3 — 1 May 2014 70 of 141
NXP Semiconductors LPC408x/7x
32-bit ARM Cortex-M4 microcontroller
• Supports single edge controlled and/or double edge controlled PWM outputs. Single
edge controlled PWM outputs all go high at the beginning of each cycle unless the
output is a constant low. Double edge controlled PWM outputs can have either edge
occur at any position within a cycle. This allows for both positive going and negative
going pulses.
• Pulse period and width can be any number of timer counts. This allows complete
flexibility in the trade-off between resolution and repetition rate. All PWM outputs will
occur at the same repetition rate.
• Double edge controlled PWM outputs can be programmed to be either positive going
or negative going pulses.
• Match register updates are synchronized with pulse outputs to prevent generation of
erroneous pulses. Software must ‘release’ new match values before they can become
effective.
• May be used as a standard 32-bit timer/counter with a programmable 32-bit prescaler
if the PWM mode is not enabled.
7.30 Motor control PWM
The LPC408x/7x contain one motor control PWM.
The motor control PWM is a specialized PWM supporting 3-phase motors and other
combinations. Feedback inputs are provided to automatically sense rotor position and use
that information to ramp speed up or down. An abort input is also provided that causes the
PWM to immediately release all motor drive outputs. At the same time, the motor control
PWM is highly configurable for other generalized timing, counting, capture, and compare
applications.
The maximum PWM speed is determined by the PWM resolution (n) and the operating
frequency f: PWM speed = f/2n (see Table 6).
7.31 Quadrature Encoder Interface (QEI)
Remark: The QEI is available on parts LPC4088/78/76.
A quadrature encoder, also known as a 2-channel incremental encoder, converts angular
displacement into two pulse signals. By monitoring both the number of pulses and the
relative phase of the two signals, the user can track the position, direction of rotation, and
velocity. In addition, a third channel, or index signal, can be used to reset the position
counter. The quadrature encoder interface decodes the digital pulses from a quadrature
encoder wheel to integrate position over time and determine direction of rotation. In
addition, the QEI can capture the velocity of the encoder wheel.
7.31.1 Features
• Tracks encoder position.

a dedicated SYSTICK exception at a 10 ms interval. In the LPC408x/7x, this timer can be
clocked from the internal AHB clock or from a device pin.
7.33 Windowed WatchDog Timer (WWDT)
The purpose of the watchdog is to reset the controller if software fails to periodically
service it within a programmable time window.
7.33.1 Features
• Internally resets chip if not periodically reloaded during the programmable time-out
period.
• Optional windowed operation requires reload to occur between a minimum and
maximum time period, both programmable.
• Optional warning interrupt can be generated at a programmable time prior to
watchdog time-out.
• Enabled by software but requires a hardware reset or a watchdog reset/interrupt to be
disabled.
• Incorrect feed sequence causes reset or interrupt if enabled.

7.34 RTC and backup registers
The RTC is a set of counters for measuring time when system power is on, and optionally
when it is off. The RTC on the LPC408x/7x is designed to have extremely low power
consumption, i.e. less than 1 A. The RTC will typically run from the main chip power
supply conserving battery power while the rest of the device is powered up. When
operating from a battery, the RTC will continue working down to 2.1 V. Battery power can
be provided from a standard 3 V lithium button cell.
An ultra-low power 32 kHz oscillator will provide a 1 Hz clock to the time counting portion
of the RTC, moving most of the power consumption out of the time counting function.
The RTC includes a calibration mechanism to allow fine-tuning the count rate in a way
that will provide less than 1 second per day error when operated at a constant voltage and
temperature.
The RTC contains a small set of backup registers (20 bytes) for holding data while the
main part of the LPC408x/7x is powered off.
The RTC includes an alarm function that can wake up the LPC408x/7x from all reduced
power modes with a time resolution of 1 s.
7.34.1 Features
• Measures the passage of time to maintain a calendar and clock.
• Ultra low power design to support battery powered systems.

• Backup registers (20 bytes) powered by VBAT.
• RTC power supply is isolated from the rest of the chip.
7.35 Event monitor/recorder
The event monitor/recorder allows recording of tampering events in sealed product
enclosures. Sensors report any attempt to open the enclosure, or to tamper with the
device in any other way. The event monitor/recorder stores records of such events when
the device is powered only by the backup battery.
7.35.1 Features
• Supports three digital event inputs in the VBAT power domain.
• An event is defined as a level change at the digital event inputs.
• For each event channel, two timestamps mark the first and the last occurrence of an
event. Each channel also has a dedicated counter tracking the total number of events.
Timestamp values are taken from the RTC.
• Runs in VBAT power domain, independent of system power supply. The
event/recorder/monitor can therefore operate in Deep power-down mode.
• Very low power consumption.

7.36 Clocking and power control
7.36.1 Crystal oscillators
The LPC408x/7x include four independent oscillators. These are the main oscillator, the
IRC oscillator, the watchdog oscillator, and the RTC oscillator.
Following reset, the LPC408x/7x will operate from the Internal RC oscillator until switched
by software. This allows systems to operate without any external crystal and the boot
loader code to operate at a known frequency.
See Figure 10 for an overview of the LPC408x/7x clock generation.

Product data sheet Rev. 3 — 1 May 2014 74 of 141
NXP Semiconductors LPC408x/7x
32-bit ARM Cortex-M4 microcontroller
7.36.1.1 Internal RC oscillator
The IRC may be used as the clock that drives the PLL and subsequently the CPU. The
nominal IRC frequency is 12 MHz. The IRC is trimmed to 1 % accuracy over the entire
voltage and temperature range.
Upon power-up or any chip reset, the LPC408x/7x use the IRC as the clock source.
Software may later switch to one of the other available clock sources.
7.36.1.2 Main oscillator
The main oscillator can be used as the clock source for the CPU, with or without using the
PLL. The main oscillator also provides the clock source for the alternate PLL1.
The main oscillator operates at frequencies of 1 MHz to 25 MHz. This frequency can be
boosted to a higher frequency, up to the maximum CPU operating frequency, by the main
PLL. The clock selected as the PLL input is PLLCLKIN. The ARM processor clock
frequency is referred to as CCLK elsewhere in this document. The frequencies of
PLLCLKIN and CCLK are the same value unless the PLL is active and connected. The
clock frequency for each peripheral can be selected individually and is referred to as
PCLK. Refer to Section 7.36.2 for additional information.
7.36.1.3 RTC oscillator
The RTC oscillator provides a 1 Hz clock to the RTC and a 32 kHz clock output that can
be output on the CLKOUT pin in order to allow trimming the RTC oscillator without
interference from a probe.
7.36.1.4 Watchdog oscillator
The Watchdog Timer has a dedicated oscillator that provides a 500 kHz clock to the
Watchdog Timer that is always running if the Watchdog Timer is enabled. The Watchdog
oscillator clock can be output on the CLKOUT pin in order to allow observe its frequency.
In order to allow Watchdog Timer operation with minimum power consumption, which can
be important in reduced power modes, the Watchdog oscillator frequency is not tightly
controlled. The Watchdog oscillator frequency will vary over temperature and power
supply within a particular part, and may vary by processing across different parts. This
variation should be taken into account when determining Watchdog reload values.
Within a particular part, temperature and power supply variations can produce up to a
17 % frequency variation. Frequency variation between devices under the same
operating conditions can be up to 30 %.
7.36.2 Main PLL (PLL0) and Alternate PLL (PLL1)
PLL0 (also called the Main PLL) and PLL1 (also called the Alternate PLL) are functionally
identical but have somewhat different input possibilities and output connections. These
possibilities are shown in Figure 10. The Main PLL can receive its input from either the
IRC or the main oscillator and can potentially be used to provide the clocks to nearly
everything on the device. The Alternate PLL receives its input only from the main oscillator
and is intended to be used as an alternate source of clocking to the USB. The USB has
timing needs that may not always be filled by the Main PLL.

Product data sheet Rev. 3 — 1 May 2014 75 of 141
NXP Semiconductors LPC408x/7x
32-bit ARM Cortex-M4 microcontroller
Both PLLs are disabled and powered off on reset. If the Alternate PLL is left disabled, the
USB clock can be supplied by PLL0 if everything is set up to provide 48 MHz to the USB
clock through that route. The source for each clock must be selected via the CLKSEL
registers and can be further reduced by clock dividers as needed.
PLL0 accepts an input clock frequency from either the IRC or the main oscillator. If only
the Main PLL is used, then its output frequency must be an integer multiple of all other
clocks needed in the system. PLL1 takes its input only from the main oscillator, requiring
an external crystal in the range of 10 to 25 MHz. In each PLL, the Current Controlled
Oscillator (CCO) operates in the range of 156 MHz to 320 MHz, so there are additional
dividers to bring the output down to the desired frequencies. The minimum output divider
value is 2, insuring that the output of the PLLs have a 50 % duty cycle.
If the USB is used, the possibilities for the CPU clock and other clocks will be limited by
the requirements that the frequency be precise and very low jitter, and that the PLL0
output must be a multiple of 48 MHz. Even multiples of 48 MHz that are within the
operating range of the PLL are 192 MHz and 288 MHz. Also, only the main oscillator in
conjunction with the PLL can meet the precision and jitter specifications for USB. It is due
to these limitations that the Alternate PLL is provided.
The alternate PLL accepts an input clock frequency from the main oscillator in the range
of 10 MHz to 25 MHz only. When used as the USB clock, the input frequency is multiplied
up to a multiple of 48 MHz (192 MHz or 288 MHz as described above).
7.36.3 Wake-up timer
The LPC408x/7x begin operation at power-up and when awakened from Power-down
mode by using the 12 MHz IRC oscillator as the clock source. This allows chip operation
to resume quickly. If the main oscillator or the PLL is needed by the application, software
will need to enable these features and wait for them to stabilize before they are used as a
clock source.
When the main oscillator is initially activated, the wake-up timer allows software to ensure
that the main oscillator is fully functional before the processor uses it as a clock source
and starts to execute instructions. This is important at power on, all types of reset, and
whenever any of the aforementioned functions are turned off for any reason. Since the
oscillator and other functions are turned off during Power-down mode, any wake-up of the
processor from Power-down mode makes use of the wake-up Timer.
The wake-up timer monitors the crystal oscillator to check whether it is safe to begin code
execution. When power is applied to the chip, or when some event caused the chip to exit
Power-down mode, some time is required for the oscillator to produce a signal of sufficient
amplitude to drive the clock logic. The amount of time depends on many factors, including
the rate of VDD(3V3) ramp (in the case of power on), the type of crystal and its electrical
characteristics (if a quartz crystal is used), as well as any other external circuitry (e.g.,
capacitors), and the characteristics of the oscillator itself under the existing ambient
conditions.
7.36.4 Power control
The LPC408x/7x support a variety of power control features. There are four special
modes of processor power reduction: Sleep mode, Deep-sleep mode, Power-down mode,
and Deep power-down mode. The CPU clock rate may also be controlled as needed by
changing clock sources, reconfiguring PLL values, and/or altering the CPU clock divider

NXP Semiconductors LPC408x/7x
32-bit ARM Cortex-M4 microcontroller
value. This allows a trade-off of power versus processing speed based on application
requirements. In addition, the peripheral power control allows shutting down the clocks to
individual on-chip peripherals, allowing fine tuning of power consumption by eliminating all
dynamic power use in any peripherals that are not required for the application. Each of the
peripherals has its own clock divider which provides even better power control.
The integrated PMU (Power Management Unit) automatically adjusts internal regulators
to minimize power consumption during Sleep, Deep-sleep, Power-down, and Deep
power-down modes.
The LPC408x/7x also implement a separate power domain to allow turning off power to
the bulk of the device while maintaining operation of the RTC and a small set of registers
for storing data during any of the power-down modes.
7.36.4.1 Sleep mode
When Sleep mode is entered, the clock to the core is stopped. Resumption from the Sleep
mode does not need any special sequence other than re-enabling the clock to the ARM
core.
In Sleep mode, execution of instructions is suspended until either a Reset or interrupt
occurs. Peripheral functions continue operation during Sleep mode and may generate
interrupts to cause the processor to resume execution. Sleep mode eliminates dynamic
power used by the processor itself, memory systems and related controllers, and internal
buses.
The DMA controller can continue to work in Sleep mode and has access to the peripheral
RAMs and all peripheral registers. The flash memory and the main SRAM are not
available in Sleep mode, they are disabled in order to save power.
Wake-up from Sleep mode will occur whenever any enabled interrupt occurs.
7.36.4.2 Deep-sleep mode
In Deep-sleep mode, the oscillator is shut down and the chip receives no internal clocks.
The processor state and registers, peripheral registers, and internal SRAM values are
preserved throughout Deep-sleep mode and the logic levels of chip pins remain static.
The output of the IRC is disabled but the IRC is not powered down to allow fast wake-up.
The RTC oscillator is not stopped because the RTC interrupts may be used as the
wake-up source. The PLL is automatically turned off and disconnected. The clock divider
registers are automatically reset to zero.
The Deep-sleep mode can be terminated and normal operation resumed by either a
Reset or certain specific interrupts that are able to function without clocks. Since all
dynamic operation of the chip is suspended, Deep-sleep mode reduces chip power
consumption to a very low value. Power to the flash memory is left on in Deep-sleep
mode, allowing a very quick wake-up.
Wake-up from Deep-sleep mode can initiated by the NMI, External Interrupts EINT0
through EINT3, GPIO interrupts, the Ethernet Wake-on-LAN interrupt, Brownout Detect,
an RTC Alarm interrupt, a USB input pin transition (USB activity interrupt), a CAN input
pin transition, or a Watchdog Timer time-out, when the related interrupt is enabled.
Wake-up will occur whenever any enabled interrupt occurs.

Product data sheet Rev. 3 — 1 May 2014 77 of 141
NXP Semiconductors LPC408x/7x
32-bit ARM Cortex-M4 microcontroller
On wake-up from Deep-sleep mode, the code execution and peripherals activities will
resume after four cycles expire if the IRC was used before entering Deep-sleep mode. If
the main external oscillator was used, the code execution will resume when 4096 cycles
expire. PLL and clock dividers need to be reconfigured accordingly.
7.36.4.3 Power-down mode
Power-down mode does everything that Deep-sleep mode does but also turns off the
power to the IRC oscillator and the flash memory. This saves more power but requires
waiting for resumption of flash operation before execution of code or data access in the
flash memory can be accomplished.
When the chip enters Power-down mode, the IRC, the main oscillator, and all clocks are
stopped. The RTC remains running if it has been enabled and RTC interrupts may be
used to wake up the CPU. The flash is forced into Power-down mode. The PLLs are
automatically turned off and the clock selection multiplexers are set to use the system
clock sysclk (the reset state). The clock divider control registers are automatically reset to
zero. If the Watchdog timer is running, it will continue running in Power-down mode.
On the wake-up of Power-down mode, if the IRC was used before entering Power-down
mode, it will take IRC 60 s to start-up. After this four IRC cycles will expire before the
code execution can then be resumed if the code was running from SRAM. In the
meantime, the flash wake-up timer then counts 12 MHz IRC clock cycles to make the
100 s flash start-up time. When it times out, access to the flash will be allowed. Users
need to reconfigure the PLL and clock dividers accordingly.
7.36.4.4 Deep power-down mode
The Deep power-down mode can only be entered from the RTC block. In Deep
power-down mode, power is shut off to the entire chip with the exception of the RTC
module and the RESET pin.
To optimize power conservation, the user has the additional option of turning off or
retaining power to the 32 kHz oscillator. It is also possible to use external circuitry to turn
off power to the on-chip regulator via the VDD(REG)(3V3) pins and/or the I/O power via the
VDD(3V3) pins after entering Deep Power-down mode. Power must be restored before
device operation can be restarted.
The LPC408x/7x can wake up from Deep power-down mode via the RESET pin or an
alarm match event of the RTC.
7.36.4.5 Wake-up Interrupt Controller (WIC)
The WIC allows the CPU to automatically wake up from any enabled priority interrupt that
can occur while the clocks are stopped in Deep-sleep, Power-down, and Deep
power-down modes.
The WIC works in connection with the Nested Vectored Interrupt Controller (NVIC). When
the CPU enters Deep-sleep, Power-down, or Deep power-down mode, the NVIC sends a
mask of the current interrupt situation to the WIC. This mask includes all of the interrupts
that are both enabled and of sufficient priority to be serviced immediately. With this
information, the WIC simply notices when one of the interrupts has occurred and then it
wakes up the CPU.
The WIC eliminates the need to periodically wake up the CPU and poll the interrupts
resulting in additional power savings.

32-bit ARM Cortex-M4 microcontroller
7.36.5 Peripheral power control
A power control for peripherals feature allows individual peripherals to be turned off if they
are not needed in the application, resulting in additional power savings.
7.36.6 Power domains
The LPC408x/7x provide two independent power domains that allow the bulk of the
device to have power removed while maintaining operation of the RTC and the backup
registers.
On the LPC408x/7x, I/O pads are powered by VDD(3V3), while VDD(REG)(3V3) powers the
on-chip voltage regulator which in turn provides power to the CPU and most of the
peripherals.
Depending on the LPC408x/7x application, a design can use two power options to
manage power consumption.
The first option assumes that power consumption is not a concern and the design ties the
VDD(3V3) and VDD(REG)(3V3) pins together. This approach requires only one 3.3 V power
supply for both pads, the CPU, and peripherals. While this solution is simple, it does not
support powering down the I/O pad ring “on the fly” while keeping the CPU and
peripherals alive.
The second option uses two power supplies; a 3.3 V supply for the I/O pads (VDD(3V3)) and
a dedicated 3.3 V supply for the CPU (VDD(REG)(3V3)). Having the on-chip voltage regulator
powered independently from the I/O pad ring enables shutting down of the I/O pad power
supply “on the fly” while the CPU and peripherals stay active.
The VBAT pin supplies power only to the RTC domain. The RTC requires a minimum of
power to operate, which can be supplied by an external battery. The device core power
(VDD(REG)(3V3)) is used to operate the RTC whenever VDD(REG)(3V3) is present. There is no
power drain from the RTC battery when VDD(REG)(3V3) is available and VDD(REG)(3V3) >
VBAT.

7.37 System control
7.37.1 Reset
Reset has four sources on the LPC408x/7x: the RESET pin, the Watchdog reset,
Power-On Reset (POR), and the BrownOut Detection (BOD) circuit. The RESET pin is a
Schmitt trigger input pin. Assertion of chip Reset by any source, once the operating
voltage attains a usable level, starts the Wake-up timer (see description in
Section 7.36.3), causing reset to remain asserted until the external Reset is de-asserted,
the oscillator is running, a fixed number of clocks have passed, and the flash controller
has completed its initialization.
When the internal Reset is removed, the processor begins executing at address 0, which
is initially the Reset vector mapped from the boot block. At that point, all of the processor
and peripheral registers have been initialized to predetermined values.

32-bit ARM Cortex-M4 microcontroller
7.37.2 Brownout detection
The LPC408x/7x include 2-stage monitoring of the voltage on the VDD(REG)(3V3) pins. If this
voltage falls below 2.2 V (typical), the BOD asserts an interrupt signal to the Vectored
Interrupt Controller. This signal can be enabled for interrupt in the Interrupt Enable
Register in the NVIC in order to cause a CPU interrupt; if not, software can monitor the
signal by reading a dedicated status register.
The second stage of low-voltage detection asserts reset to inactivate the LPC408x/7x
when the voltage on the VDD(REG)(3V3) pins falls below 1.85 V (typical). This reset prevents
alteration of the flash as operation of the various elements of the chip would otherwise
become unreliable due to low voltage. The BOD circuit maintains this reset down below
1 V, at which point the power-on reset circuitry maintains the overall reset.
Both the 2.2 V and 1.85 V thresholds include some hysteresis. In normal operation, this
hysteresis allows the 2.2 V detection to reliably interrupt, or a regularly executed event
loop to sense the condition.
7.37.3 Code security (Code Read Protection - CRP)
This feature of the LPC408x/7x allows user to enable different levels of security in the
system so that access to the on-chip flash and use of the JTAG and ISP can be restricted.
When needed, CRP is invoked by programming a specific pattern into a dedicated flash
location. IAP commands are not affected by the CRP.
There are three levels of the Code Read Protection.
CRP1 disables access to chip via the JTAG and allows partial flash update (excluding
flash sector 0) using a limited set of the ISP commands. This mode is useful when CRP is
required and flash field updates are needed but all sectors can not be erased.
CRP2 disables access to chip via the JTAG and only allows full flash erase and update
using a reduced set of the ISP commands.
Running an application with level CRP3 selected fully disables any access to chip via the
JTAG pins and the ISP. This mode effectively disables ISP override using P2[10] pin, too.
It is up to the user’s application to provide (if needed) flash update mechanism using IAP
calls or call reinvoke ISP command to enable flash update via UART0.
7.37.4 APB interface
The APB peripherals are split into two separate APB buses in order to distribute the bus
bandwidth and thereby reducing stalls caused by contention between the CPU and the
GPDMA controller.
CAUTION
If level three Code Read Protection (CRP3) is selected, no future factory testing can be
performed on the device.

7.37.5 AHB multilayer matrix
The LPC408x/7x use an AHB multilayer matrix. This matrix connects the instruction
(I-code) and data (D-code) CPU buses of the ARM Cortex-M4 to the flash memory, the
main (32 kB) static RAM, and the Boot ROM. The GPDMA can also access all of these
memories. Additionally, the matrix connects the CPU system bus and all of the DMA
controllers to the various peripheral functions.
7.37.6 External interrupt inputs
The LPC408x/7x include up to 30 edge sensitive interrupt inputs combined with one level
sensitive external interrupt input as selectable pin function. The external interrupt input
can optionally be used to wake up the processor from Power-down mode.
7.37.7 Memory mapping control
The Cortex-M4 incorporates a mechanism that allows remapping the interrupt vector table
to alternate locations in the memory map. This is controlled via the Vector Table Offset
Register contained in the NVIC.
The vector table may be located anywhere within the bottom 1 GB of Cortex-M4 address
space. The vector table must be located on a 128 word (512 byte) boundary because the
NVIC on the LPC408x/7x is configured for 128 total interrupts.
7.38 Debug control
Debug and trace functions are integrated into the ARM Cortex-M4. Serial wire debug and
trace functions are supported in addition to a standard JTAG debug and parallel trace
functions. The ARM Cortex-M4 is configured to support up to eight breakpoints and four
watch points.

10.2 Peripheral power consumption
The supply current per peripheral is measured as the difference in supply current between
the peripheral block enabled and the peripheral block disabled in the PCONP register. All
other blocks are disabled and no code is executed. Measured on a typical sample at
Tamb = 25 C. The peripheral clock was set to PCLK = CCLK/4 with CCLK = 12 MHz,
48 MHz, and 120 MHz.
The combined current of several peripherals running at the same time can be less than
the sum of each individual peripheral current measured separately.

11.6 SSP interface
[1] The minimum clock cycle time, and therefore the maximum frequency of the SSP in master mode, is limited
by the pin electronics to the value given. The SSP block should not be configured to generate a clock faster
than that. At and below the maximum frequency, Tcy(clk) = (SSPCLKDIV (1 + SCR) CPSDVSR) / fmain.
The clock cycle time derived from the SPI bit rate Tcy(clk) is a function of the main clock frequency fmain, the
SSP peripheral clock divider (SSPCLKDIV), the SSP SCR parameter (specified in the SSP0CR0 register),
and the SSP CPSDVSR parameter (specified in the SSP clock prescale register).
[2] Tamb = 40 C to 85 C; VDD(3V3) = 3.0 V to 3.6 V.
[3] Tcy(clk) = 12 Tcy(PCLK). The maximum clock rate in slave mode is 1/12th of the PCLK rate.
[4] Tamb = 25 C; VDD(3V3) = 3.3 V.

11.7 I2C-bus
[1] See the I2C-bus specification UM10204 for details.
[2] Parameters are valid over operating temperature range unless otherwise specified.
[3] tHD;DAT is the data hold time that is measured from the falling edge of SCL; applies to data in transmission
and the acknowledge.
[4] A device must internally provide a hold time of at least 300 ns for the SDA signal (with respect to the
VIH(min) of the SCL signal) to bridge the undefined region of the falling edge of SCL.
[5] Cb = total capacitance of one bus line in pF.
[6] The maximum tf for the SDA and SCL bus lines is specified at 300 ns. The maximum fall time for the SDA
output stage tf is specified at 250 ns. This allows series protection resistors to be connected in between the
SDA and the SCL pins and the SDA/SCL bus lines without exceeding the maximum specified tf.
[7] In Fast-mode Plus, fall time is specified the same for both output stage and bus timing. If series resistors
are used, designers should allow for this when considering bus timing.
[8] The maximum tHD;DAT could be 3.45 s and 0.9 s for Standard-mode and Fast-mode but must be less than
the maximum of tVD;DAT or tVD;ACK by a transition time (see UM10204). This maximum must only be met if
the device does not stretch the LOW period (tLOW) of the SCL signal. If the clock stretches the SCL, the
data must be valid by the set-up time before it releases the clock.
[9] tSU;DAT is the data set-up time that is measured with respect to the rising edge of SCL; applies to data in
transmission and the acknowledge.
[10] A Fast-mode I2C-bus device can be used in a Standard-mode I2C-bus system but the requirement tSU;DAT =
250 ns must then be met. This will automatically be the case if the device does not stretch the LOW period
of the SCL signal. If such a device does stretch the LOW period of the SCL signal, it must output the next
data bit to the SDA line tr(max) + tSU;DAT = 1000 + 250 = 1250 ns (according to the Standard-mode I2C-bus
specification) before the SCL line is released. Also the acknowledge timing must meet this set-up time.

[1] VDDA and VREFP should be tied to VDD(3V3) if the ADC and DAC are not used.
[2] Conditions: VSSA = 0 V, VDDA = 3.3 V.
[3] The ADC is monotonic, there are no missing codes.
[4] The differential linearity error (ED) is the difference between the actual step width and the ideal step width.
See Figure 32.
[5] The integral non-linearity (EL(adj)) is the peak difference between the center of the steps of the actual and
the ideal transfer curve after appropriate adjustment of gain and offset errors. See Figure 32.
[6] The offset error (EO) is the absolute difference between the straight line which fits the actual curve and the
straight line which fits the ideal curve. See Figure 32.
[7] The gain error (EG) is the relative difference in percent between the straight line fitting the actual transfer
curve after removing offset error, and the straight line which fits the ideal transfer curve. See Figure 32.
[8] The absolute error (ET) is the maximum difference between the center of the steps of the actual transfer
curve of the non-calibrated ADC and the ideal transfer curve. See Figure 32.
[9] In single-conversion mode.
[10] See Figure 33.
[11] 8-bit resolution is achieved by ignoring the lower four bits of the ADC conversion result.

13.2 Crystal oscillator XTAL input and component selection
The input voltage to the on-chip oscillators is limited to 1.8 V. If the oscillator is driven by a
clock in slave mode, it is recommended that the input be coupled through a capacitor with
Ci = 100 pF. To limit the input voltage to the specified range, choose an additional
capacitor to ground Cg which attenuates the input voltage by a factor Ci/(Ci + Cg). In slave
mode, a minimum of 200 mV(RMS) is needed.

NXP Semiconductors LPC408x/7x
32-bit ARM Cortex-M4 microcontroller
In slave mode the input clock signal should be coupled by means of a capacitor of 100 pF
(Figure 40), with an amplitude between 200 mV(RMS) and 1000 mV(RMS). This
corresponds to a square wave signal with a signal swing of between 280 mV and 1.4 V.
The XTALOUT pin in this configuration can be left unconnected.
External components and models used in oscillation mode are shown in Figure 41 and in
Table 34 and Table 35. Since the feedback resistance is integrated on chip, only a crystal
and the capacitances CX1 and CX2 need to be connected externally in case of
fundamental mode oscillation (the fundamental frequency is represented by L, CL and
RS). Capacitance CP in Figure 41 represents the parallel package capacitance and should
not be larger than 7 pF. Parameters FOSC, CL, RS and CP are supplied by the crystal
manufacturer.

13.3 XTAL Printed-Circuit Board (PCB) layout guidelines
The crystal should be connected on the PCB as close as possible to the oscillator input
and output pins of the chip. Take care that the load capacitors Cx1, Cx2, and Cx3 in case of
third overtone crystal usage have a common ground plane. The external components
must also be connected to the ground plane. Loops must be made as small as possible in
order to keep the noise coupled in via the PCB as small as possible. Also parasitics
should stay as small as possible. Smaller values of Cx1 and Cx2 should be chosen
according to the increase in parasitics of the PCB layout.
13.4 Standard I/O pin configuration
Figure 42 shows the possible pin modes for standard I/O pins with analog input function:
• Digital output driver: Open-drain mode enabled/disabled
• Digital input: Pull-up enabled/disabled
• Digital input: Pull-down enabled/disabled
• Digital input: Repeater mode enabled/disabled
• Analog input
The default configuration for standard I/O pins is input with pull-up enabled. The weak
MOS devices provide a drive capability equivalent to pull-up and pull-down resistors.

1. Introduction
This document describes the functionality and electrical specifications of the
transceiver IC PN512.
The PN512 is a highly integrated transceiver IC for contactless communication at
13.56 MHz. This transceiver IC utilizes an outstanding modulation and demodulation
concept completely integrated for different kinds of contactless communication methods
and protocols at 13.56 MHz.
1.1 Different available versions
The PN512 is available in three versions:
• PN5120A0HN1/C2 (HVQFN32), PN5120A0HN/C2 (HVQFN40) and PN5120A0ET/C2
(TFBGA64), hereafter named as version 2.0
• PN512AA0HN1/C2 (HVQFN32) and PN512AA0HN1/C2BI (HVQFN32 with Burn In),
hereafter named as industrial version, fulfilling the automotive qualification stated in
AEC-Q100 grade 3 from the Automotive Electronics Council, defining the critical
stress test qualification for automotive integrated circuits (ICs).
• PN5120A0HN1/C1(HVQFN32) and PN5120A0HN/C1 (HVQFN40), hereafter named
as version 1.0
The data sheet describes the functionality for the industrial version and version 2.0. The
differences of the version 1.0 to the version 2.0 are summarized in Section 21. The
industrial version has only differences within the outlined characteristics and limitations.
2. General description
The PN512 transceiver ICs support 4 different operating modes
• Reader/Writer mode supporting ISO/IEC 14443A/MIFARE and FeliCa scheme
• Reader/Writer mode supporting ISO/IEC 14443B
• Card Operation mode supporting ISO/IEC 14443A/MIFARE and FeliCa scheme
• NFCIP-1 mode
Enabled in Reader/Writer mode for ISO/IEC 14443A/MIFARE, the PN512’s internal
transmitter part is able to drive a reader/writer antenna designed to communicate with
ISO/IEC 14443A/ MIFARE cards and transponders without additional active circuitry. The

decoding circuitry for signals from ISO/IEC 14443A/MIFARE compatible cards and
transponders. The digital part handles the complete ISO/IEC 14443A framing and error
detection (Parity & CRC).
The PN512 supports MIFARE 1K or MIFARE 4K emulation products. The PN512 supports
contactless communication using MIFARE higher transfer speeds up to 424 kbit/s in both
directions.
Enabled in Reader/Writer mode for FeliCa, the PN512 transceiver IC supports the FeliCa
communication scheme. The receiver part provides a robust and efficient implementation
of the demodulation and decoding circuitry for FeliCa coded signals. The digital part
handles the FeliCa framing and error detection like CRC. The PN512 supports contactless
communication using FeliCa Higher transfer speeds up to 424 kbit/s in both directions.
The PN512 supports all layers of the ISO/IEC 14443B reader/writer communication
scheme, given correct implementation of additional components, like oscillator, power
supply, coil etc. and provided that standardized protocols, e.g. like ISO/IEC 14443-4
and/or ISO/IEC 14443B anticollision are correctly implemented.
In Card Operation mode, the PN512 transceiver IC is able to answer to a reader/writer
command either according to the FeliCa or ISO/IEC 14443A/MIFARE card interface
scheme. The PN512 generates the digital load modulated signals and in addition with an
external circuit the answer can be sent back to the reader/writer. A complete card
functionality is only possible in combination with a secure IC using the S2C interface.
Additionally, the PN512 transceiver IC offers the possibility to communicate directly to an
NFCIP-1 device in the NFCIP-1 mode. The NFCIP-1 mode offers different communication
mode and transfer speeds up to 424 kbit/s according to the Ecma 340 and ISO/IEC 18092
NFCIP-1 Standard. The digital part handles the complete NFCIP-1 framing and error
detection.
Various host controller interfaces are implemented:
• 8-bit parallel interface1
• SPI interface
• serial UART (similar to RS232 with voltage levels according pad voltage supply)
• I2C interface.
A purchaser of this NXP IC has to take care for appropriate third party patent licenses.

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

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

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

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

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

8.4.2 Passive communication mode
Passive Communication mode means that the target answers to an initiator command in a
load modulation scheme. The initiator is active meaning generating the RF field.
The contactless UART of PN512 and a dedicated host controller are required to handle
the NFCIP-1 protocol.
Note: Transfer Speeds above 424 kbit/s are not defined in the NFCIP-1 standard. The
PN512 supports these transfer speeds only with dedicated external circuits.

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

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

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

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

The first send byte defines both the mode and the address byte.
[1] X = Do not care.
Remark: The MSB must be sent first.
10.2.3 SPI address byte
The address byte has to meet the following format.
The MSB of the first byte defines the mode used. To read data from the PN512 the MSB is
set to logic 1. To write data to the PN512 the MSB must be set to logic 0. Bits 6 to 1 define
the address and the LSB is set to logic 0.
10.3 UART interface
10.3.1 Connection to a host
Remark: Signals DTRQ and MX can be disabled by clearing TestPinEnReg register’s
RS232LineEn bit.
10.3.2 Selectable UART transfer speeds
The internal UART interface is compatible with an RS232 serial interface.
The default transfer speed is 9.6 kBd. To change the transfer speed, the host controller
must write a value for the new transfer speed to the SerialSpeedReg register. Bits
BR_T0[2:0] and BR_T1[4:0] define the factors for setting the transfer speed in the
SerialSpeedReg register.
The BR_T0[2:0] and BR_T1[4:0] settings are described in Table 10. Examples of different
transfer speeds and the relevant register settings are given in Table 11.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

12.7.3 Additional hardware support for FeliCa and NFC
Additionally to the polling sequence support for the Felica mode, the PN512 supports the
check of the Len-byte.
The received Len-byte in accordance to the registers FelNFC1Reg and FelNFC2Reg:
DataLenMin in register FelNFC1Reg defines the minimum length of the accepted packet
length. This register is six bit long. Each bit represents a length of four bytes.
DataLenMax in register FelNFC2Reg defines the maximum length of the accepted
package. This register is six bit long. Each bit represents a length of four bytes. If set to
logic 1 this limit is ignored. If the length is not in the supposed range, the packet is not
transferred to the FIFO and receiving is kept active.
Example 1:
• DataLenMin = 4
– The length shall be greater or equal 16.
• DataLenMax = 5
– The length shall be smaller than 20. Valid area: 16, 17, 18, 19
Example 2:
• DataLenMin = 9
– The length shall be greater or equal 36.
• DataLenMax = 0
– The length shall be smaller than 256. Valid area: 36 to 255
12.7.4 CRC coprocessor
The following CRC coprocessor parameters can be configured:
• The CRC preset value can be either 0000h, 6363h, A671h or FFFFh depending on
the ModeReg register’s CRCPreset[1:0] bits setting
• The CRC polynomial for the 16-bit CRC is fixed to x16 + x12 + x5 + 1
• The CRCResultReg register indicates the result of the CRC calculation. This register
is split into two 8-bit registers representing the higher and lower bytes.
• The ModeReg register’s MSBFirst bit indicates that data will be loaded with the MSB
first.

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

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

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

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

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

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

19.3 PN512 command overview
19.3.1 PN512 command descriptions
19.3.1.1 Idle
Places the PN512 in Idle mode. The Idle command also terminates itself.
19.3.1.2 Config command
To use the automatic MIFARE Anticollision, FeliCa Polling and NFCID3 the data used for
these transactions has to be stored internally. All the following data have to be written to
the FIFO in this order:
SENS_RES (2 bytes); in order byte 0, byte 1
NFCID1 (3 Bytes); in order byte 0, byte 1, byte 2; the first NFCID1 byte is fixed to 08h and
the check byte is calculated automatically.
SEL_RES (1 Byte)
polling response (2 bytes (shall be 01h, FEh) + 6 bytes NFCID2 + 8 bytes Pad + 2 bytes
system code)
NFCID3 (1 byte)
In total 25 bytes are transferred into an internal buffer.
The complete NFCID3 is 10 bytes long and consists of the 3 NFCID1 bytes, the 6 NFCID2
bytes and the one NFCID3 byte which are listed above.
To read out this configuration the command Config with an empty FIFO-buffer has to be
started. In this case the 25 bytes are transferred from the internal buffer to the FIFO.

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

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

MIFARE (Card Operation mode):
The MIFARE anticollision is finished and the command has automatically changed to
transceive. The FIFO contains the first command after the Select. The bit TargetActivated
in the Status2Reg register is set to logic 1.
Felica (Card Operation mode):
The FeliCa polling command is finished and the command has automatically changed to
transceive. The FIFO contains the first command followed after the Poling by the FeliCa
protocol. The bit TargetActivated in the Status2Reg register is set to logic 1.
19.3.1.10 MFAuthent
This command manages MIFARE authentication to enable a secure communication to
any MIFARE Mini, MIFARE 1K and MIFARE 4K card. The following data is written to the
FIFO buffer before the command can be activated:
• Authentication command code (60h, 61h)
• Block address
• Sector key byte 0
• Sector key byte 1
• Sector key byte 2
• Sector key byte 3
• Sector key byte 4
• Sector key byte 5
• Card serial number byte 0
• Card serial number byte 1
• Card serial number byte 2
• Card serial number byte 3
In total 12 bytes are written to the FIFO.
Remark: When the MFAuthent command is active all access to the FIFO buffer is
blocked. However, if there is access to the FIFO buffer, the ErrorReg register’s WrErr bit is
set.
This command automatically terminates when the MIFARE card is authenticated and the
Status2Reg register’s MFCrypto1On bit is set to logic 1.
This command does not terminate automatically if the card does not answer, so the timer
must be initialized to automatic mode. In this case, in addition to the IdleIRq bit, the
TimerIRq bit can be used as the termination criteria. During authentication processing, the
RxIRq bit and TxIRq bit are blocked. The Crypto1On bit is only valid after termination of
the MFAuthent command, either after processing the protocol or writing Idle to the
CommandReg register.
If an error occurs during authentication, the ErrorReg register’s ProtocolErr bit is set to
logic 1 and the Status2Reg register’s Crypto1On bit is set to logic 0.

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