CAN, 10-bit ADC and external memory interface

General description
The LPC2292/LPC2294 are based on a 16/32 bit ARM7TDMI-STM 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.
