100 Year Data Retention
CAT28HT64 features hardware and software write pro-
tection.
The CAT28HT64 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 Ceramic DIP package.
