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, a RDY/BUSY pin and Toggle status bits signal the start and end of the self-timed write cycle. Additionally, the CAT28C65B features hardware and software write protection. The CAT28C65B 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 JEDECapproved 28-pin DIP, 28-pin TSOP, 28-pin SOIC or 32pin PLCC packages. BLOCK DIAGRAM A5–A12 ADDR. BUFFER & LATCHES INADVERTENT WRITE PROTECTION R...
