CXP80712B/80716B/80720B/80724B
CMOS 8-bit Single Chip Microcomputer
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.
