CXP81732A/81740A
CMOS 8-bit Single Chip Microcomputer
Description
100 pin QFP (PIastic)
100 pin LQFP (PIastic)
The CXP81732A/81740A 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.
Structure
Also CXP81732A/81740A provides sleep/stop
function which enables to lower power consumption
and ultra-low speed instruction mode in 32kHz
operation.
