DESCRIPTION

The CAT28F102 is a high speed 64K x 16-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 algo-

rithm. 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 CAT28F102 is manufactured using Catalyst’s ad-

vanced 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 40-pin DIP, 44-pin PLCC, or 40-pin TSOP

packages.
