Sony CXP827P16 Datasheet

CXP827P16

CMOS 8-bit Single Chip Microcomputer

Description

The CXP827P16 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 panel controller/driver, remote control receiver,
PWM output circuit and 32kHz timer/counter.

This IC also includes sleep/stop functions which
can be used to achieve low power consumption.

CXP827P16 is the PROM-incorporated version of
the CXP82716 with built-in mask ROM, and it is able to
write directly into the program. Thus, it is most suitable
for evaluation use during system development and for
small-quantity production.
