CXP88852/88860
CMOS 8-bit Single Chip Microcomputer
Description
The CXP88852/88860 is a CMOS 8-bit micro-
computer which consists of A/D converter, serial
interface, timer/counter, time base timer, high
precision timing pattern generation circuits, PWM
output, VISS/ VASS circuit, 32kHz timer/counter,
remote control receiving circuit, VSYNC separator
and the measurement circuit which measure signals
of capstan FG amplifier and drum FG/PG amplifier
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, CXP88852/88860 provides sleep/stop function
which enables to lower power consumption.
