DESCRIPTION
The CAT28LV256 is a fast, low power, low voltage
CMOS Parallel E2PROM organized as 32K 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 VCC power up/down write protection
eliminate additional timing and protection hardware.
DATA Polling and Toggle status bits signal the start and
end of the self-timed write cycle. Additionally, the
CAT28LV256 features hardware and software write
protection.
The CAT28LV256 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 or 32-pin PLCC
packages.
