CMOS 8-bit Single Chip Microcomputer

Description

The CXP83508/83512/83516 and the CXP83509/

83513/83517 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 CXP83508/83512/83516 and the CXP83509/

83513/83517 also provide a sleep/stop function that

enables lower power consumption.
