Description

CXP84340 is a CMOS 8-bit single chip microcomputer integrating on a single chip an A/D converter, serial interface, timer/counter, time base timer, capture timer/counter, remote control reception circuit, and the like besides the basic configurations of 8-bit CPU, ROM, RAM, and I/O port.
The CXP84340 also provides a power-on reset function and a sleep/stop function that enables lower power consumption.
