CXP82316

Description

The CXP82316/82320/82324 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, time base timer, capture timer/counter, fluorescent display controller/driver, remote control receiver.
This device also includes a power-on reset function and sleep/stop functions which can be used to achieve low power consumption.
