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.
