Description

The CXP82712/82716 microcomputer is composed of a 8-bit CPU, ROM, 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, fluorescent display controller/driver, remote control receiver, PWM output circuit and 32kHz timer/counter.

This device also includes sleep/stop functions which can be used to achieve low power consumption.
