DESCRIPTION

The CAT28LV64 is a low voltage, low power, CMOS

parallel EEPROM organized as 8K x 8-bits. It requires a

simple interface for in-system programming. On-chip

addressanddatalatches,self-timedwritecyclewithauto-

clear and V_CCpower up/down write protection eliminate

additional timing and protection hardware. DATA Polling

and Toggle status bit signal the start and end of the self-

timed write cycle. Additionally, the CAT28LV64 features

hardware and software write protection.

The CAT28LV64 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, 28-pin TSOP, 28-pin SOIC or 32-

pin PLCC packages.
