CXP81720A/81724A

CMOS 8-bit Single Chip Microcomputer

For the availability of this product, please contact the sales office.

Description

The CXP81720A/81724A 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 receiving circuit,

as well as basic configurations like 8-bit CPU, ROM,

RAM and I/O port. They are integrated into a single

chip.

Also CXP81720A/81724A provides sleep/stop

function which enables to lower power consumption

and ultra-low speed instruction mode in 32kHz

operation.
