CXP88140

CXP88132/88140 CMOS 8-bit Single Chip Microcomputer 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. 100 pin QFP (Plastic) Structure Silicon gate CMOS IC Features A wide instruction set (213 instructions) which cover various types of data — 16-bit arithmetic instruction/multiplication and division instructions/boolean bit operation instruction Minimum instruction cycle During operation 250ns/16MHz, During operation 122µs/32kHz Incorporated ROM capacity 32Kbytes (CXP88132), 40Kbytes (CXP88140) Incorporated RAM capacity 1296bytes Peripheral function — A/D converter 8-bit, 8-channel, successive approximation system (Conversion time: 20.0µs/16MHz) — Serial I/O with auto transfer mode Incorporated 8-stage FIFO for data (1 to 8 bytes auto transfer) — Timer 8-bit timer/counter, 2-chann...
