CXP81120/81124
CMOS 8-bit Single Chip Microcomputer
Description
The CXP81120/81124 is a CMOS 8-bit micro-
computer which consists of A/D converter, serial
interface, timer/counter, time base timer, PWM
output, as well as basic configurations like 8-bit
CPU, ROM, RAM and I/O port. They are integrated
into a single chip.
Also the CXP81120/81124 provides power-on reset
function, sleep/stop function which enables to lower
power consumption.
