CXP81720B/81724B
CMOS 8-bit Single Chip Microcomputer
Description
The CXP81720B/81724B is a CMOS 8-bit micro-
computer which consists of A/D converter, serial
interface, timer/counter, time-base timer, high-
precision timing pattern generation circuit, PWM
output, 32kHz timer/counter, remote control reception
circuit, as well as basic configurations like 8-bit CPU,
ROM, RAM and I/O port. They are integrated into a
single chip.
Also CXP81720B/81724B provides sleep/stop
functions which enables to lower power consumption.
