Description

The CXP82432A/82440A 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 and high-speed output circuit besides the basic configurations of 8-bit CPU, ROM, RAM, and I/O port.

The CXP82432A/82440A also provides sleep/stop function that enables lower power consumption.
