CXP81952M

CXP81952M/81960M CMOS 8-bit Single Chip Microcomputer Description The CXP81952M/81960M 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, 32kHz timer/event counter, remote control reception circuit, and FRC capture unit, as well as basic configurations like 8-bit CPU, ROM, RAM and I/O port. They are integrated into a single chip. Also the CXP81952M/81960M provides sleep/stop functions which enable 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 covers various types of data — 16-bit operation/multiplication and division/Boolean bit operation instructions Minimum instruction cycle 200ns at 20MHz operation (4.5 to 5.5V) 333ns at 12MHz operation (2.7 to 5.5V) 122µs at 32kHz operation Incorporated ROM capacity 52K bytes (CXP81952M), 60K bytes (CXP81960M) Incorporated RAM capacity 2048 bytes Peripheral functions — A/D converter 8 bits, 12 channels, successive approximation system (Conversion time of 16µs at 20MHz) — Serial Interface Incorporated buffer RAM (1 to 32 bytes auto transfer), 1 channel Incorporated 8-bit and 8-stage FIFO (1 to 8 bytes auto transfer), 1 channel — Timer 8-bit timer, 8-bit timer/counter, 19-bit time base timer, 32kHz ti...
