CXP81952M/81960M

CMOS 8-bit Single Chip Microcomputer

Description

The CXP81952M/81960M is a CMOS 8-bit micro-

computer 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.
