Description

The CXP88132/88140 is a CMOS 8-bit microcomputer which consists of A/D converter, serial interface, timer/counter, time base timer, vector interruption, high precision timing pattern generation circuits, PWM generator, PWM for tuner, VISS/VASS circuit, 32kHz timer/event counter, remote control receiving circuit, FDP controller/driver, VCR vertical sync separation circuit and the measuring 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, CXP88132/88140 provides sleep/ stop function which enables to lower power consumption and ultra-low speed instruction mode in 32kHz operation.
