Description
The CXP874P60 is a CMOS 8-bit microcomputer 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, PROM, RAM and I/O port. They are integrated into a single chip.
