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.
