ally, the CAT28LV65 features hardware and software
write protection.
The CAT28LV65 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 packages.
