CXP88348

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. 100 pin QFP (Plastic) Structure Silicon gate CMOS IC Features A wide instruction set (213 instructions) which covers various types of data — 16-bit arithmetic/multiplication and division/boolean bit operation instructions Minimum instruction cycle 250ns at 16MHz operation 122µs at 32kHz operation Incorporated ROM capacity 40K bytes (CXP88340) 48K bytes (CXP88348) Incorporated RAM capacity 1376 bytes Peripheral functions — A/D converter 8 bits, 12 channels, successive approximation system (Conversion time of 20µs/16MHz) — Serial interface Incorporated 8-bit, 8-stage FIFO (Auto transfer for 1 to 8 bytes), 1 channel Incorporated buffer RAM (Auto transfer for 1 to 32 bytes), 1 channnel Incorporated two-wire 8-bit and 8-stage FIFO (Auto transfer for 1 to 8 bytes), 1 channel — Timer 8-bit timer/counter, 2 channels 19-bit tim...
