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 CAT28LV256 features hardware and software write protection. The CAT28LV256 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 or 32-pin PLCC packages. BLOCK DIAGRAM 28LV256 F01 © 2004 by Catalyst Semiconductor, Inc.
