Description

The CXP82320 microcomputer is composed of a CPU, ROM and RAM, and I/O ports. These chips feature many other high-performance circuits in a single-chip CMOS design, including an A/D converter, serial interface, timer/counter, timebase timer, capture timer/counter, fluorescent display controller/driver, remote control receiver.
This CXP82320 also includes a power-on reset function and sleep/stop functions which can be used to achieve low power consumption.
