CXP87452/87460

CMOS 8-bit Single Chip Microcomputer

Description

The CXP87452/87460 is a CMOS 8-bit micro-

computer which consists of A/D converter, serial

interface (2ch independently), timer/counter, time

base timer, vector interruption, high precision timing

pattern generation circuit (PPG 2ch independently,

RTG 2ch independently), PWM generator, general

purpose prescaler, PWM for tuner, VCR vertical

sync separation circuit and the measuring circuit

which measure signals of capstan FG and drum

FG/PG 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.

100 pin QFP (PIastic)

100 pin LQFP (PIastic)

Structure

Silicon gate CMOS IC

Also CXP87452/87460 provides power on reset

function, sleep/stop function which enables to lower

power consumption .
