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 CAT28C512/513 features hardware and software write protection. The CAT28C512/513 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 32-pin DIP, PLCC and TSOP packages. BLOCK DIAGRAM ADDR. BUFFER & LATCHES INADVERTENT WRITE PROTECTION ROW DECODER 65,536 x 8 EEPROM ARRAY 128 BYTE PAGE R...
