CMOS 8-bit Single Chip Microcomputer

Description

The CXP841P24 is a CMOS 8-bit microcomputer

integrating on a single chip an A/D converter, serial

interface, timer/counter, time base timer, capture

timer/counter, and remote control reception circuit

besides the basic configurations of 8-bit CPU, ROM,

RAM, and I/O port.

The CXP841P24 also provides a sleep/stop function

that enables lower power consumption.

This IC is the PROM-incorporated version of the

CXP84124 with built-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.
