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 system minimally and download code to other loca-
tions of CAT28F001.

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.
