CXP82220/82224

CMOS 8-bit Single Chip Microcomputer

Description

The CXP82220/82224 is a CMOS 8-bit single chip

microcomputer integrating on a single chip an A/D

converter, serial interface, timer/counter, time base

timer, capture timer/counter, fluorescent display tube

controller/driver, remote control reception circuit, CTL

duty detection circuit, 14-bit PWM output, high-speed

output circuit and other servo systems besides the

basic configurations of 8-bit CPU, PROM, RAM, and

I/O port.

The CXP82220/82224 also provides power-on reset

function and sleep/stop function that enables lower

power consumption.
