CAT28C257  
256 kb CMOS Parallel  
EEPROM  
Description  
The CAT28C257 is a fast, low power, 5 Vonly CMOS Parallel  
EEPROM organized as 32K x 8bits. It requires a simple interface for  
insystem programming. Onchip address and data latches,

selftimed write cycle with autoclear and V power up/down write  
CC  
protection eliminate additional timing and protection hardware. DATA  
Polling and Toggle status bits signal the start and end of the selftimed  
write cycle. Additionally, the CAT28C257 features hardware and  
software write protection.  
The CAT28C257 is manufactured using ON Semiconductor’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 28pin DIP or 32pin  
PLCC packages.
