DESCRIPTION
The CAT28C256 is a fast, low power, 5V-only CMOS
parallel E
2
PROM 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 V
CC
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 CAT28C256 features
hardware and software write protection.
The CAT28C256 is manufactured using Catalyst鈥檚 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 or 32-pin PLCC
packages.
