LPC2104/2105/2106 Single-chip 32-bit microcontrollers; 128 kB ISP/IAP flash with 16/32/64 kB RAM Rev. 07 — 20 June 2008 Product data sheet 1. General description The UART are based on a 16/32-bit ARM7TDMI-S CPU with real-time emulation and embedded trace support, together with 128 kB of embedded high speed flash memory. A 128-bit wide memory interface and a unique accelerator architecture enable 32-bit code execution at maximum clock rate. For critical code size applications, the alternative 16-bit Thumb mode reduces code by more than 30 % with minimal performance penalty. Due to their tiny size and low power consumption, these microcontrollers are ideal for applications where miniaturization is a key requirement, such as access control and point-of-sale. With a wide range of serial communications interfaces and on-chip SRAM options up to 64 kB, they are very well suited for communication gateways and protocol converters, soft modems, voice recognition and low end imaging, providing both large buffer size and high processing power. Various 32-bit timers, PWM channels, and 32 GPIO lines make these microcontrollers particularly suitable for industrial control and medical systems. Remark: Throughout the data sheet, the term LPC2104/2105/2106 will apply to devices with and without /00 and /01 suffixes. Suffixes will be used to differentiate devices whenever they include new features. 2.

Functional description 6.1 Architectural overview The ARM7TDMI-S is a general purpose 32-bit microprocessor, which offers high performance and very low power consumption. The ARM architecture is based on Reduced Instruction Set Computer (RISC) principles, and the instruction set and related decode mechanism are much simpler than those of microprogrammed Complex Instruction Set Computers. This simplicity results in a high instruction throughput and impressive real-time interrupt response from a small and cost-effective processor core. 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 ARM7TDMI-S processor also employs a unique architectural strategy 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 is that of a super-reduced instruction set. Essentially, the ARM7TDMI-S processor has two instruction sets: • The standard 32-bit ARM set. • A 16-bit Thumb set. The Thumb set’s 16-bit instruction length allows it to approach twice the density of standard ARM code while retaining most of the ARM’s performance advantage over a traditional 16-bit processor using 16-bit registers. This is possible because Thumb code operates on the same 32-bit register set as ARM code. Thumb code is able to provide up to 65 % of the code size of ARM, and 160 % of the performance of an equivalent ARM processor connected to a 16-bit memory system. 6.2 On-chip flash program memory The LPC2104/2105/2106 incorporate a 128 kB flash memory system. This memory may be used for both code and data storage. Programming of the flash memory may be accomplished in several ways. It may be programmed In System via the serial port. The application program may also erase and/or program the flash while the application is running, allowing a great degree of flexibility for data storage field firmware upgrades, etc. When on-chip bootloader is used, 120 kB of flash memory is available for user code. The LPC2104/2105/2106 flash memory provides a minimum of 100000 erase/write cycles and 20 years of data retention. 6.3 On-chip static RAM On-chip static RAM may be used for code and/or data storage. The SRAM may be accessed as 8 bit, 16 bit, and 32 bit. The LPC2104/2105/2106 provide 16/32/64 kB of static RAM, respectively. LPC2104_2105_2106_7 © NXP B.V. 2008. All rights reserved.

In addition, the CPU interrupt vectors may be re-mapped to allow them to reside in either flash memory (the default) or on-chip static RAM.

The programmable assignment scheme means that priorities of interrupts from the various peripherals can be dynamically assigned and adjusted. Fast Interrupt reQuest (FIQ) has the highest priority. If more than one request is assigned to FIQ, the VIC combines the requests to produce the FIQ signal to the ARM processor. The fastest possible FIQ latency is achieved when only one request is classified as FIQ, because then the FIQ service routine can simply start dealing with that device. But if more than one request is assigned to the FIQ class, the FIQ service routine can read a word from the VIC that identifies which FIQ source(s) is (are) requesting an interrupt. Vectored IRQs have the middle priority. Sixteen of the interrupt requests can be assigned to this category. Any of the interrupt requests can be assigned to any of the 16 vectored IRQ slots, among which slot 0 has the highest priority and slot 15 has the lowest. Non-vectored IRQs have the lowest priority. The VIC combines the requests from all the vectored and non-vectored IRQs to produce the IRQ signal to the ARM processor. The IRQ service routine can start by reading a register from the VIC and jumping there. If any of the vectored IRQs are requesting, the VIC provides the address of the highest-priority requesting IRQs service routine, otherwise it provides the address of a default routine that is shared by all the non-vectored IRQs. The default routine can read another VIC register to see what IRQs are active. 6.5.1 Interrupt sources Table 4 lists the interrupt sources for each peripheral function. Each peripheral device has one interrupt line connected to the Vectored Interrupt Controller, but may have several internal interrupt flags. Individual interrupt flags may also represent more than one interrupt source. Table 4.

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. 6.9.1 Features • Direction control of individual bits. • Separate control of output set and clear. • All I/O default to inputs after reset. 6.9.2 Features added with the Fast GPIO set of registers available on LPC2104/2105/2106/01 only • Fast GPIO registers are relocated to the ARM local bus for the fastest possible I/O timing, enabling port pin toggling up to 3.5 times faster than earlier LPC2000 devices. • Mask registers allow treating sets of port bits as a group, leaving other bits unchanged. • All Fast GPIO registers are byte addressable. • Entire port value can be written in one instruction. • Ports are accessible via either the legacy group of registers (GPIOs) or the group of registers providing accelerated port access (Fast GPIOs). 6.10 UARTs The LPC2104/2105/2106 each contain two UARTs.

In addition, auto-CTS/RTS flow-control functions are fully implemented in hardware. • Fractional baud rate generator enables standard baud rates such as 115200 Bd to be achieved with any crystal frequency above 2 MHz. • Autobauding. • Auto-CTS/RTS flow-control fully implemented in hardware. 6.11 I2C-bus serial I/O controller I2C is a bidirectional bus 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. I2C is a multi-master bus, it can be controlled by more than one bus master connected to it. The I2C-bus implemented in LPC2104/2105/2106 supports bit rate up to 400 kbit/s (Fast I2C-bus). 6.11.1 Features • Standard I2C compliant bus interface. • Easy to configure as Master, Slave or Master/Slave. • Programmable clocks allow versatile rate control. • Bidirectional data transfer between masters and slaves. • Multi-master bus (no central master). • Arbitration between simultaneously transmitting masters without corruption of serial data on the bus. • 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. • The I2C-bus may be used for test and diagnostic purposes.

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 a byte of data to the slave, and the slave always sends a byte of data to the master. 6.12.1 Features • Compliant with Serial Peripheral Interface (SPI) specification. • Synchronous, serial, full duplex communication. • Combined SPI master and slave. • Maximum data bit rate of one eighth of the input clock rate. 6.12.2 Features available in LPC2104/2105/2106/01 only • Selectable transfer width of eight to 16 bit per frame. • When the SPI interface is used in Master mode, the SSEL pin is not needed (can be used for a different function). 6.13 SSP controller (LPC2104/2015/2106/01 only) The SSP is a controller 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. Data transfers are in principle full duplex, with frames of four to 16 bits of data flowing from the master to the slave and from the slave to the master. Because the SSP and SPI peripherals share the same physical pins, it is not possible to have both of these two peripherals active at the same time. Application can switch on the fly from SPI to SSP and back. 6.13.1 Features • Compatible with Motorola’s SPI, Texas Instrument’s 4-wire SSI, and National Semiconductor’s Microwire buses. • • • • Synchronous serial communication. Master or slave operation. 8-frame FIFOs for both transmit and receive. Four to 16 bits per frame. 6.14 General purpose timers The Timer is designed to count cycles of the peripheral clock (PCLK) and optionally generate interrupts or perform other actions at specified timer values, based on four match registers. It also includes up to four capture inputs to trap the timer value when an input signal transitions, optionally generating an interrupt. LPC2104_2105_2106_7 © NXP B.V. 2008. All rights reserved.

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 (Timer 1) and three (Timer 0) 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. 6.14.2 Features available in LPC2104/2105/2106/01 only The LPC2104/2105/2106/01 can count external events on one of the capture inputs if the external pulse lasts at least one half of the period of the PCLK. In this configuration, unused capture lines can be selected as regular timer capture inputs or used as external interrupts. • Timer can count cycles of either the peripheral clock (PCLK) or an externally supplied clock. • When counting cycles of an externally supplied clock, only one of the timer’s capture inputs can be selected as the timer’s clock. The rate of such a clock is limited to PCLK⁄ . Duration of HIGH/LOW levels on the selected CAP input cannot be shorter 4 than 1⁄(2PCLK). 6.15 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. 6.15.1 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.

The RTC has been designed to use little power, making it suitable for battery powered systems where the CPU is not running continuously (Idle mode). 6.16.1 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. • Programmable Reference Clock Divider allows adjustment of the RTC to match various crystal frequencies. 6.17 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 LPC2104/2105/2106. The Timer is designed to count cycles of the peripheral clock (PCLK) and optionally generate interrupts or perform other actions when specified timer values occur, based on seven match registers. It also includes four capture inputs to save the timer value when an input signal transitions, and optionally generate an interrupt when those events occur. 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 (MR0) 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 MR0 match occurs. Three match registers can be used to provide a PWM output with both edges controlled. Again, the MR0 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. LPC2104_2105_2106_7 © NXP B.V. 2008.

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). 6.17.1 Features • Seven match registers allow up to six single edge controlled or three 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. • 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 timer if the PWM mode is not enabled. • A 32-bit Timer/Counter with a programmable 32-bit Prescaler. 6.18 System control 6.18.1 Crystal oscillator The oscillator supports crystals in the range of 1 MHz to 25 MHz. The oscillator output frequency is called FOSC and the ARM processor clock frequency is referred to as CCLK for purposes of rate equations, etc. FOSC and CCLK are the same value unless the PLL is running and connected. Refer to Section 6.18.2 “PLL” for additional information. 6.18.2 PLL The PLL accepts an input clock frequency in the range of 10 MHz to 25 MHz. The input frequency is multiplied up into the range of 10 MHz to 60 MHz with a Current Controlled Oscillator (CCO). The multiplier can be an integer value from 1 to 32 (in practice, the multiplier value cannot be higher than 6 on this family of microcontrollers due to the upper frequency limit of the CPU). 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. The output divider may be set to divide LPC2104_2105_2106_7 © NXP B.V. 2008. All rights reserved.

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, then connect to the PLL as a clock source. The PLL settling time is 100 µs. 6.18.3 Reset and wake-up timer Reset has two sources on the LPC2104/2105/2106: the RESET pin and Watchdog Reset. The RESET pin is a Schmitt trigger input pin with an additional glitch filter. Assertion of chip Reset by any source starts the wake-up timer (see wake-up timer description below), causing the internal chip reset to remain asserted until the external Reset is de-asserted, the oscillator is running, a fixed number of clocks have passed, and the on-chip flash controller has completed its initialization. When the internal Reset is removed, the processor begins executing at address 0, which is the Reset vector. At that point, all of the processor and peripheral registers have been initialized to predetermined values. The wake-up timer ensures that the oscillator and other analog functions required for chip operation are fully functional before the processor is allowed 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 as the means of checking whether it is safe to begin code execution. When power is applied to the chip, or 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 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. 6.18.4 Code security (Code Read Protection - CRP) This feature of the LPC2104/2105/2106/01 allows the 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: 1. CRP1 disables access to the 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. 2. CRP2 disables access to the chip via the JTAG and only allows full flash erase and update using a reduced set of the ISP commands. LPC2104_2105_2106_7 © NXP B.V. 2008. All rights reserved.

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 P0[14] pin, too. It is up to the user’s application to provide (if needed) a flash update mechanism using IAP calls or a call to reinvoke ISP command to enable flash update via UART 0. CAUTION If level three Code Read Protection (CRP3) is selected, no future factory testing can be performed on the device. 6.18.5 External interrupt inputs The LPC2104/2105/2106 include three external interrupt inputs as selectable pin functions. The external interrupt inputs can optionally be used to wake up the processor from Power-down mode. 6.18.6 Memory mapping control The Memory mapping control alters the mapping of the interrupt vectors that appear beginning at address 0x0000 0000. Vectors may be mapped to the bottom of the on-chip flash memory, or to the on-chip static RAM. This allows code running in different memory spaces to have control of the interrupts. 6.18.7 Power control The LPC2104/2105/2106 support two reduced power modes: Idle mode and Power-down mode. In Idle mode, execution of instructions is suspended until either a Reset or interrupt occurs. Peripheral functions continue operation during Idle mode and may generate interrupts to cause the processor to resume execution. Idle mode eliminates power used by the processor itself, memory systems and related controllers, and internal buses. In Power-down 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 Power-down mode and the logic levels of chip output pins remain static. The Power-down 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, Power-down mode reduces chip power consumption to nearly zero. The power can be controlled for each peripheral individually allowing peripherals to be turned off if they are not needed in the application and resulting in additional power savings. 6.18.8 APB The APB divider determines the relationship between the processor clock (CCLK) and the clock used by peripheral devices (PCLK). The APB divider serves two purposes. The first is to provide peripherals with the desired PCLK via APB so that they can operate at the speed chosen for the ARM processor. In order to achieve this, the APB may be slowed down to 1⁄2 to 1⁄4 of the processor clock rate. Because the APB must work properly at power-up (and its timing cannot be altered if it does not work since the APB divider control registers reside on the APB), the default condition at reset is for the APB to run at 1⁄4 of the LPC2104_2105_2106_7 © NXP B.V. 2008.

The second purpose of the APB divider is to allow power savings when an application does not require any peripherals to run at the full processor rate. Because the APB divider is connected to the PLL output, the PLL remains active (if it was running) during Idle mode. 6.19 Emulation and debugging The LPC2104/2105/2106 support emulation and debugging via a JTAG serial port. A trace port allows tracing program execution. Each of these functions requires a trade-off of debugging features versus device pins. Because the LPC2104/2105/2106 are provided in a small package, there is no room for permanently assigned JTAG or Trace pins. An alternate JTAG port allows an option to debug functions assigned to the pins used by the primary JTAG port (see Section 6.8). 6.19.1 EmbeddedICE 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 EmbeddedICE protocol convertor. EmbeddedICE protocol convertor converts the Remote Debug Protocol commands to the JTAG data needed to access the ARM core. The ARM core has a Debug Communication Channel 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 even entering the debug state. The debug communication channel is accessed as a co-processor 14 by the program running on the ARM7TDMI-S core. The debug communication channel allows the JTAG port to be used for sending and receiving data without affecting the normal program flow. The debug communication channel data and control registers are mapped in to addresses in the EmbeddedICE logic. The JTAG clock (TCK) must be slower than 1⁄6 of the CPU clock (CCLK) for the JTAG interface to operate. 6.19.2 Embedded trace Since the LPC2104/2105/2106 have significant amounts of on-chip memory, it is not possible to determine how the processor core is operating simply by observing the external pins. The Embedded Trace Macrocell (ETM) provides real-time trace capability for deeply embedded processor cores. It outputs information about processor execution to the trace port. The ETM is connected directly to the ARM core and not to the main AMBA system bus. It compresses the trace information and exports it through a narrow trace port. An external trace port analyzer must capture the trace information under software debugger control. Instruction trace (or PC trace) 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. Trace information generation can be controlled by selecting the trigger resource. Trigger resources include address comparators, counters and sequencers. Since trace information is compressed the software debugger requires a static image of the code being executed. Self-modifying code cannot be traced because of this restriction.
