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.

*COMMENT
Stresses above those listed under “Absolute Maximum
Ratings” may cause permanent damage to the device.
These are stress ratings only, and functional operation of
the device at these or any other conditions outside of those
listed in the operational sections of this specification is not
implied. Exposure to any absolute maximum rating for
extended periods may affect device performance and
reliability.

Note:
(1) The minimum DC input voltage is –0.5V. During transitions, inputs may undershoot to –2.0V for periods of less than 20 ns. Maximum DC
voltage on output pins is VCC +0.5V, which may overshoot to VCC + 2.0V for periods of less than 20ns.
(2) Output shorted for no more than one second. No more than one output shorted at a time.
(3) This parameter is tested initially and after a design or process change that affects the parameter.
(4) Latch-up protection is provided for stresses up to 100 mA on address and data pins from –1V to VCC +1V.
