CXP87852/87860
CMOS 8-bit Single Chip Microcomputer
Description
The CXP87852/87860 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 reception
circuit, HSYNC counter, 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 the CXP87852/87860 provides sleep/stop
functions which enable to lower power consumption.
