CXP82712/82716
CMOS 8-bit Single Chip Microcomputer
Description
The CXP82712/82716 microcomputer is composed
64 pin SDIP (Plastic)
of a 8-bit 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, fluorescent display controller/driver, remote
control receiver, PWM output circuit and 32kHz
timer/counter.
This device also includes sleep/stop functions which
can be used to achieve low power consumption.
