LPC2290概述

　LPC2290 is based on a 16/32-bit ARM7TDMI-S, and support real-time simulation and tracking of the CPU. Strict control of the code size of applications can use 16-bit Thumb mode reduces code by more than 30%, while the performance loss is very small.

　　LPC2290 using 144-pin package, low power consumption, various 32-bit timer, 8-channel 10-bit ADC, 2 way advanced CAN channels, PWM channels and up to nine external interrupt, this microcontroller suitable for automation applications, they also apply to industrial control, medical systems, access control and fault tolerance to maintain bus applications. Set via the bus, LPC2290 has 76 GPIO. With a wide range of serial communications interfaces, they are also well suited for communication gateways and protocol converters, embedded software, modems, and other types of applications.
