CMOS 8-bit Single Chip Microcomputer

Description

The CXP83620/83624 and the CXP83621/83625

are CMOS 8-bit single chip microcomputer integrating

on a single chip an A/D converter, serial interface,

timer/counter, time-base timer, sub timer/counter, LCD

controller/driver and remote control reception circuit

besides the basic configurations of 8-bit CPU, ROM,

RAM, and I/O port.

The CXP83620/83624 and the CXP83621/83625 also

provide a sleep/stop function that enables lower power

consumption.
