Description
The CXP80712A/80716A/80720A/80724A is a CMOS
8-bit microcomputer which consists of A/D converter,
serial interface, timer/counter, time base timer, vector
interruption, high precision timing pattern generation
circuit, PWM generator, PWM for tuner, VISS/VASS
circuit, 32kHz timer/event counter, remote control
receiving circuit, 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 CXP80712A/80716A/80720A/80724A provides
sleep/stop function which enables to lower power
consumption and ultra-low speed instruction mode in
32kHz operation.
