CAT28C257
256 kb CMOS Parallel
EEPROM
Description
The CAT28C257 is a fast, low power, 5 V−only CMOS Parallel
EEPROM 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 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 28−pin DIP or 32−pin
PLCC packages.
