CXP82612/82616
CMOS 8-bit Single Chip Microcomputer
Description
The CXP82612/82616 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,
fluorescent display controller/driver, remote control
receiver and 32kHz timer/counter.
This device also includes a power-on reset function
and sleep/stop functions which can be used to
achieve low power consumption.
