Overview

CXP88452/88460 CMOS 8-bit Single Chip Microcomputer Description The CXP88452/88460 is a CMOS 8-bit microcomputer which consists of A/D converter, serial interface, timer/counter, time-base timer, high precision timing pattern generation circuit, PWM output, VISS/VASS circuit, 32kHz timer/counter, remote control receiving circuit, VSYNC separator and the measurement 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.
Also, the CXP88452/88460 provides sleep/stop functions which enable to lower power consumption.
