CXP81720B/81724B

CMOS 8-bit Single Chip Microcomputer

Description

The CXP81720B/81724B is a CMOS 8-bit micro-

computer which consists of A/D converter, serial

interface, timer/counter, time-base timer, high-

precision timing pattern generation circuit, PWM

output, 32kHz timer/counter, remote control reception

circuit, as well as basic configurations like 8-bit CPU,

ROM, RAM and I/O port. They are integrated into a

single chip.

Also CXP81720B/81724B provides sleep/stop

functions which enables to lower power consumption.
