Description

The CXP80712B/80716B/80720B/80724B 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 measures 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 CXP80712B/80716B/80720B/80724B provides sleep/stop function which enables to lower power consumption.
