CMOS 8-bit Single Chip Microcomputer

Description

The CXP82532/82540 microcomputer is composed

of a 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, 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.
