DESCRIPTION  
The CAT28C256 is a fast, low power, 5V-only CMOS  
parallel EEPROM organized as 32K x 8-bits. It requires a  
simple interface for in-system programming. On-chip  
addressanddatalatches,self-timedwritecyclewithauto-  
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 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.
