CXP82432A/82440A
CMOS 8-bit Single Chip Microcomputer
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.
