CXP82032/82040/82052/82060
CMOS 8-bit Single Chip Microcomputer
Description
100 pin QFP (Plastic)
The CXP82032/82040/82052/82060 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 panel controller/driver, remote control
reception circuit, and PWM output besides the basic
configurations of 8-bit CPU, ROM, RAM, and I/O port.
The CXP82032/82040/82052/82060 also provides
sleep/stop function that enables lower power
consumption.
