CMOS 8-bit Single Chip Microcomputer
CXP83620/83624
CXP83621/83625
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.
