1.General descriptionThe LPC2109/2119/2129 are based on a 16/32-bit ARM7TDMI-S CPU with real-timeemulation and embedded trace support, together with 64/128/256 kB of embeddedhigh-speed flash memory. A 128-bit wide memory interface and a unique acceleratorarchitecture enable 32-bit code execution at maximum clock rate. For critical code sizeapplications, the alternative 16-bit Thumb mode reduces code by more than 30 % withminimal performance penalty.With their compact 64-pin package, low power consumption, various 32-bit timers,4-channel 10-bit ADC, two advanced CAN channels, PWM channels and 46 fast GPIOlines with up to nine external interrupt pins these microcontrollers are particularly suitablefor automotive and industrial control applications, as well as medical systems andfault-tolerant maintenance buses. With a wide range of additional serial communicationsinterfaces, they are also suited for communication gateways and protocol converters aswell as many other general-purpose applications.Remark: Throughout the data sheet, the term LPC2109/2119/2129 will apply to deviceswith and without the /00 or /01 suffixes. The /00 or the /01 suffix will be used todifferentiate from other devices only when necessary.2.Features2.1 Key features brought by LPC2109/2119/2129/01 devicesI Fast GPIO ports enable port pin toggling up to 3.5 times faster than the original device.They also allow for a port pin to be read at any time regardless of its function.I Dedicated result registers for ADC(s) reduce interrupt overhead. The ADC pads are5 V tolerant when configured for digital I/O function(s).I UART0/1 include fractional baud rate generator, auto-bauding capabilities andhandshake flow-control fully implemented in hardware.I Buffered SSP serial controller supporting SPI, 4-wire SSI, and Microwire formats.I SPI programmable data length and master mode enhancement.I Diversified Code Read Protection (CRP) enables different security levels to beimplemented. This feature is available in LPC2109/2119/2129/00 devices as well.I General purpose timers can operate as external event counters.2.2 Key features common for all devicesI 16/32-bit ARM7TDMI-S microcontroller in a tiny LQFP64 package.I 8/16 kB on-chip static RAM.LPC2109/2119/2129Single-chip 16/32-bit microcontrollers; 64/128/256 kB ISP/IAPflash with 10-bit ADC and CANRev. 06 — 10 December 2007Product data sheet
