DESCRIPTION

The CAT28C16A is a fast, low power, 5V-only CMOS

Parallel E

PROM organized as 2K 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 V

power up/down write protection

eliminate additional timing and protection hardware.

DATA

Polling signals the start and end of the self-timed

write cycle. Additionally, the CAT28C16A features hard-

ware write protection.

The CAT28C16A is manufactured using Catalyst’s ad-

vanced CMOS floating gate technology. It is designed to

endure 10,000 program/erase cycles and has a data

retention of 10 years. The device is available in JEDEC

approved 24-pin DIP and SOIC or 32-pin PLCC pack-

ages.
