CXP87748A

CXP87740A/87748A CMOS 8-bit Single Chip Microcomputer Description The CXP87740A/87748A 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 circuit, PWM generator, PWM for tuner, VISS/VASS circuit, 32kHz timer/event counter, remote control receiving circuit, 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 CXP87740A/87748A provides sleep/stop function which enables to lower power consumption and ultra-low speed instruction mode in 32kHz operation. 100 pin QFP (PIastic) 100 pin LQFP (PIastic) 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 333ns/12MHz (Supply voltage 3.0 to 5.5V) During operation 250ns/16MHz (Supply voltage 4.5 to 5.5V) During operation 122µs/32kHz Incorporated ROM capacity 40K bytes (CXP87740A) 48K bytes (CXP87748A) Incorporated RAM capacity 1344 bytes Peripheral functions — A/D converter 8-bit, 12-channel, successive approximation system (Conversion time 20.0µs/16MHz) — Serial interface Incorporated 8-bit and 8...
