Description

The CXP87132/87140 is a CMOS 8-bit microcomputer which consists of A/D converter, serial interface (2chindependently), 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.
Also the CXP87132/87140 provides power on reset function, sleep/stop function which enables to lower power consumption.
