CXP88732/88740/88748
CMOS 8-bit Single Chip Microcomputer
Description The CXP88732/88740/88748 is a
CMOS 8-bit microcomputer 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, CXP88732/88740/88748 provides sleep/stop function which enables to lower power consumption. 100 pin QFP (Plastic)
