DESCRIPTION

The CAT28C256 is a fast, low power, 5V-only CMOS

parallel E²PROM organized as 32K 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 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’s ad-

vancedCMOSfloatinggatetechnology. Itisdesignedto

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.
