CXP81120/81124

CMOS 8-bit Single Chip Microcomputer

Description

The CXP81120/81124 is a CMOS 8-bit micro-

computer which consists of A/D converter, serial

interface, timer/counter, time base timer, PWM

output, as well as basic configurations like 8-bit

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

into a single chip.

Also the CXP81120/81124 provides power-on reset

function, sleep/stop function which enables to lower

power consumption.
