CXP88340/88348
CMOS 8-bit Single Chip Microcomputer
Description
The CXP88340/88348 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 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, the CXP88340/88348 provides sleep/stop
functions which enable to lower power consumption.
