CMOS 8-bit Single Chip Microcomputer

Description

The CXP820P60 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 circuit besides the basic configurations

of 8-bit CPU, ROM, RAM, and I/O port.

The CXP820P60 also provides sleep/stop function

that enables lower power consumption.

CXP820P60 is the PROM-incorporated version of the

CXP82052/82060 with bult-in mask ROM. This provides

the additional feature of being able to write directly into

the program. Thus, it is most suitable for evaluation

use during system development and for small-quantity

production.
