Description
The CXP82220/82224 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, fluorescent display tube controller/driver, remote control reception circuit, CTL duty detection circuit, 14-bit PWM output, high-speed output circuit and other servo systems besides the basic configurations of 8-bit CPU, PROM, RAM, and I/O port.
The CXP82220/82224 also provides power-on reset function and sleep/stop function that enables lower power consumption.
