CXP82532/82540
CMOS 8-bit Single Chip Microcomputer
Description
The CXP82532/82540 microcomputer is composed
of a CPU, ROM RAM, and I/O ports. These chips
feature many other high-performance circuits in a
single-chip CMOS design, including an A/D
converter, serial interface, timer/counter, time-base
timer, capture timer/counter, fluorescent display
controller/driver, remote control receiver.
This device also includes a power-on reset function
and sleep/stop functions which can be used to
achieve low power consumption.
80 pin QFP (Plastic)
