DESCRIPTION

The CAT28F002 is a high speed 256K X 8-bit electrically

erasable and reprogrammable Flash memory ideally

suited for applications requiring in-system or after sale

code updates.

The CAT28F002 has a blocked architecture with one 16

KB Boot Block, two 8 KB Parameter Blocks, one 96 KB

Main Block and one 128 KB Main Block. The Boot Block

section can be at the top or bottom of the memory map.

The Boot Block section includes a reprogramming write

lock out feature to guarantee data integrity. It is de-

signed to contain secure code which will bring up the

system minimally and download code to other locations

of CAT28F002.

The CAT28F002 is designed with a signature mode

which allows the user to identify the IC manufacturer and

device type. The CAT28F002 is also designed with on-

Chip Address Latches, Data Latches, Programming and

Erase Algorithms. A deep power-down mode lowers the

total Vcc power consumption 1

µw typical.

The CAT28F002 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 40-pin TSOP and 40-pin PDIP packages.
