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 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 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.
