DESCRIPTION

The CAT28LV65 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

address and data latches, self-timed write cycle with

auto-clear and V

power up/down write protection

eliminate additional timing and protection hardware.

DATA

Polling, RDY/BUSY and Toggle status bit signal

the start and end of the self-timed write cycle. Additionally,

the CAT28LV65 features hardware and software write

protection.

The CAT28LV65 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.
