CXP508L4/508L6

CMOS 4-bit Single Chip Microcomputer

For the availability of this product, please contact the sales office.

Description

64 pin SDIP (Plastic)

64 pin QFP (Plastic)

The CXP508L4/508L6 is a CMOS 4-bit micro-

computer which consists of 4-bit CPU, ROM, RAM,

I/O port, 8-bit timer, 8-bit timer/counter, 18-bit time

base timer, 8-bit serial I/O, vector interruption, and a

liquid crystal displayer (LCD) controller/driver. They

are integrated into a single clip with the standby

function etc. which are to be operated at low power

consumption.

Structure

Features

Silicon gate CMOS IC
