It requires a simple interface for in-system programming. On-chip address and data latches, self-timed write cycle with autoclear and VCC power up/down write protection eliminate additional timing and protection hardware. DATA Polling and Toggle status bit signal the start and end of the selftimed write cycle. Additionally, the CAT28LV64 features hardware and software write protection. The CAT28LV64 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 32pin PLCC packages. BLOCK DIAGRAM A5–A12 ADDR. BUFFER & LATCHES INADVERTENT WRITE PROTECT...
