DESCRIPTION

using a two write cycle scheme. Address and Data are

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

write operation.

TheCAT28F020isahighspeed256Kx8-bitelectrically

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.

The CAT28F020 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 32-pin plastic DIP, 32-pin PLCC or 32-pin

TSOP packages.

It is pin and Read timing compatible with standard

EPROM and E²PROM devices. Programming and

Erase are performed through an operation and verify

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