DESCRIPTION

The CAT28F001 is a high speed 128K X 8 bit electrically

erasable and reprogrammable Flash memory ideally

suited for applications requiring in-system or after sale

code updates.

The CAT28F001 has a blocked architecture with one 8

KB Boot Block, two 4 KB Parameter Blocks and one 112

KB Main Block. The Boot Block section can be at the top

or bottom of the memory map and includes a reprogram-

ming write lock out feature to guarantee data integrity. It

is designed to contain secure code which will bring up

The CAT28F001 is designed with a signature mode

which allows the user to identify the IC manufacturer and

device type. The CAT28F001 is also designed with on-

Chip Address Latches, Data Latches, Programming and

Erase Algorithms.

The CAT28F001 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, PLCC or TSOP packages.
