CMOS 8-bit Single Chip Microcomputer

Description

The CXP87532/87540 is a CMOS 8-bit micro-

computer which consists of arithmetic coprocessor,

A/D converter, serial interface, timer/counter, time

base timer, vector interruption, high precision timing

pattern generation circuit, PWM generator and the

measuring circuit which measures signals of capstan

FG, drum FG/PG, reel FG and other servo systems,

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

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

chip.

Also this IC provides power on reset function,

sleep/stop function which enables to lower power

consumption.
