DESCRIPTION
The CAT28F010 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. Electrical erasure of the full memory
contents is achieved typically within 0.5 second.
It is pin and Read timing compatible with standard
EPROM and EEPROM devices. Programming and
Erase are performed through an operation and verify
algorithm. The instructions are input via the I/O bus,
using a two write cycle scheme. Address and Data are
latched to free the I/O bus and address bus during the
write operation.
The CAT28F010 is manufactured using Catalyst’s
advanced 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, 32-pin PLCC or 32-pin
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.

CC
+ 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.

Note:
(1) This parameter is tested initially and after a design or process change that affects the parameter.
(2) Output floating (High-Z) is defined as the state where the external data line is no longer driven by the output buffer.
(3) Input Rise and Fall Times (10% to 90%) < 10 ns.
(4) Input Pulse Levels = 0.45V and 2.4V. For High Speed Input Pulse Levels 0.0V and 3.0V.
(5) Input and Output Timing Reference = 0.8V and 2.0V. For High Speed Input and Output Timing Reference = 1.5V.
(6) Low-Z is defined as the state where the external data may be driven by the output buffer but may not be valid.
