DESCRIPTION
The CAT28C64B is a fast, low power, 5V-only CMOS
Parallel EEPROM organized as 8K x 8-bits. It requires a
simple interface for in-system programming. On-chip
address and data latches, self-timed write cycle with
auto-clear and V
CC
power up/down write protection
eliminate additional timing and protection hardware.
DATA
Polling and Toggle status bits signal the start and
end of the self-timed write cycle. Additionally, the
CAT28C64B features hardware and software write
protection.
The CAT28C64B 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 100 years. The device is available in JEDEC-
approved 28-pin DIP, TSOP, SOIC, or, 32-pin PLCC
package .

*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 specifica-
tion is not implied. Exposure to any absolute maximum
rating for extended periods may affect device perfor-
mance and reliability.
