1. INTRODUCTION

GENERAL DESCRIPTION
The LPC2119/2129/2292/2294 are based on a 16/32 bit ARM7TDMI-S
support, together with 128/256 kilobytes (kB) of embedded high speed flash memory. A 128-bit wide internal 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.
With their comapct 64 and 144 pin packages, low power consumption, various 32-bit timers, 4-channel 10-bit ADC, 2 advanced
CAN channels and 46 GPIOs or 8-channel 10-bit ADC, 4 advanced CAN channels and at least 76 GPIOs (64 and 144 pin
package respectively), and up to 9 external interrupt pins these microcontrollers are particularly suitable for industrial control,
medical systems, access control and point-of-sale. With wide range of serial communications interfaces, they are also very well
suited for communication gateways, protocol converters and embedded soft modems as well as many other general-purpose
applications.
FEATURES
• 16/32-bit ARM7TDMI-S microcontroller in a 64 or 144 pin package.
• 16 kB on-chip Static RAM
• 128/256 kB on-chip Flash Program Memory. 128-bit wide interface/accelerator enables high speed 60 MHz operation.
• External 8, 16 or 32-bit bus (144 pin package)
• In-System Programming (ISP) and In-Application Programming (IAP) via on-chip boot-loader software. Flash programming
takes 1 ms per 512 byte line. Single sector or full chip erase takes 400 ms.
• EmbeddedICE-RT interface enables breakpoints and watch points. Interrupt service routines can continue to execute whilst
the foreground task is debugged with the on-chip RealMonitor software.
• Embedded Trace Macrocell enables non-intrusive high speed real-time tracing of instruction execution.
• Two/four interconnected CAN interfaces with advanced acceptance filters.
• Four/eight channel (64/144 pin package) 10-bit A/D converter with conversion time as low as 2.44 ms.
• Two 32-bit timers (with 4 capture and 4 compare channels), PWM unit (6 outputs), Real Time Clock and Watchdog.
• Multiple serial interfaces including two UARTs (16C550), Fast I
• 60 MHz maximum CPU clock available from programmable on-chip Phase-Locked Loop.
• Vectored Interrupt Controller with configurable priorities and vector addresses.
• Up to forty-six (64 pin) and seventy-six (144 pin package) 5 V tolerant general purpose I/O pins. Up to 12 independent external
interrupt pins available (EIN and CAP functions).
• On-chip crystal oscillator with an operating range of 10 MHz to 25 MHz.
• Two low power modes, Idle and Power-down.
• Processor wake-up from Power-down mode via external interrupt.
• Individual enable/disable of peripheral functions for power optimization.
• Dual power supply.
- CPU operating voltage range of 1.65V to 1.95V (1.8V +/- 8.3%).
- I/O power supply range of 3.0V to 3.6V (3.3V +/- 10%).
