DESCRIPTION

The CAT28HT256 is a fast, low power, 5V-only CMOS

parallel E2PROM organized as 32K x 8-bits. It requires

a simple interface for in-system programming. On-chip

address and data latches, self-timed write cycle with

auto-clear and VCC power up/down write protection

eliminate additional timing and protection hardware.

DATA Polling and Toggle status bits signal the start and

end of the self-timed write cycle. Additionally, the

CAT28HT256 features hardware and software write

protection as well as an internal Error Correction Code

(ECC) for extremely high reliability.

The CAT28HT256 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 100 years. The device is available in JEDEC

approved 28-pin Ceramic DIP package.
