DESCRIPTION

The CAT28F020 is a high speed 256K x 8-bit electrically

erasable and reprogrammable Flash memory ideally

suited for applications requiring in-system or after-sale

code updates. Electrical erasure of the full memory

contents is achieved typically within 0.5 second.

It is pin and Read timing compatible with standard

EPROM and E

PROM devices. Programming and

Erase are performed through an operation and verify

algorithm. The instructions are input via the I/O bus,

using a two write cycle scheme. Address and Data are

latched to free the I/O bus and address bus during the

write operation.

The CAT28F020 is manufactured using Catalyst’s

advanced CMOS floating gate technology. It is designed

to endure 100,000 program/erase cycles and has a data

retention of 10 years. The device is available in JEDEC

approved 32-pin plastic DIP, 32-pin PLCC or 32-pin

TSOP packages.
