LPC2292/LPC2294

16/32-bit ARM microcontrollers; 256 kB ISP/IAP Flash with

CAN, 10-bit ADC and external memory interface

Rev. 01 — 05 February 2004

Preliminary data

1. General description

The LPC2292/LPC2294 are based on a 16/32 bit ARM7TDMI-S™ CPU with real-time

emulation and embedded trace support, together with 256 kilobytes (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.

With their 144 pin package, low power consumption, various 32-bit timers, 8-channel

10-bit ADC, 2/4 (LP2292/LPC2294) advanced CAN channels, PWM channels and up

to 9 external interrupt pins these microcontrollers are particularly suitable for

automotive and industrial control applications as well as medical systems and

fault-tolerant maintenance buses. Number of available GPIOs ranges from 76 (with

external memory) through 112 (single-chip). With a wide range of additional serial

communications interfaces, they are also suited for communication gateways and

protocol converters as well as many other general-purpose applications.

2. Features

2.1 Key features

■ 16/32-bit ARM7TDMI-S microcontroller in a LQFP144 package.

■ 16 kB on-chip Static RAM and 256 kB on-chip Flash Program Memory. 128-bit

wide interface/accelerator enables high speed 60 MHz operation.

■ 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 and Embedded Trace interfaces offer real-time debugging with

the on-chip RealMonitor software as well as high speed real-time tracing of

instruction execution.

■ Two/four (LPC2292/2294) interconnected CAN interfaces with advanced

acceptance ﬁlters. Additional serial interfaces include two UARTs (16C550), Fast

I²C (400 kbits/s) and two SPIs™.

■ Eight channel 10-bit A/D converter with conversion time as low as 2.44 µs.

■ Two 32-bit timers (with 4 capture and 4 compare channels), PWM unit (6 outputs),

Real Time Clock and Watchdog.

■ Vectored Interrupt Controller with conﬁgurable priorities and vector addresses.

■ Conﬁgurable external memory interface with up to four banks, each up to 16 Mb

and 8/16/32 bit data width.

■ Up to 112 general purpose I/O pins (5 V tolerant). Up to 9 edge/level sensitive

external interrupt pins available.
