PROM 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

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 pro-
tection.

100 Year Data Retention
The CAT28C64B 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 100 years. The device is available in JEDEC-
approved 28-pin DIP, 28-pin TSOP, 28-pin SOIC, or, 32-
pin PLCC package .
