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
CC
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.
