LPC2290
16/32-bit ARM microcontroller with CAN, 10-bit ADC and
external memory interface
Rev. 03 — 16 November 2006
Product data sheet
1. General description
The LPC2290 microcontroller is based on a 16/32-bit ARM7TDMI-S CPU with real-time
emulation and embedded trace support. For critical code size applications, the alternative
16-bit Thumb mode reduces code by more than 30 % with minimal performance penalty.
With its 144-pin package, low power consumption, various 32-bit timers, 8-channel 10-bit
ADC, two advanced CAN channels, PWM channels and up to nine external interrupt pins
this microcontroller is particularly suitable for automotive and industrial control
applications as well as medical systems and fault-tolerant maintenance buses. The
LPC2290 provides up to 76 GPIOs depending on bus configuration. With a wide range of
additional serial communications interfaces, it is also suited for communication gateways
and protocol converters as well as many other general-purpose applications.
Remark:
Throughout the data sheet, the term ‘LPC2290’ will apply to devices with and
without the /01 suffix. New devices will use the /01 suffix to differentiate from the original
devices only when necessary.
