The CAT28C64B is a fast, low power, 5V-only CMOS Parallel E² PROM organized as 8K 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 CAT28C64B features hardware and software write protection.

The CAT28C64B is manufactured using Catalyst'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, 28-pin TSOP, 28-pin SOIC, or, 32- pin PLCC package .
