Product Summary

The CAT28C256LI-12T is a fast, low power, 5V-only CMOS parallel EEPROM organized as 32K x 8-bits. The CAT28C256LI-12T 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 CAT28C256 features hardware and software write protection. The CAT28C256LI-12T 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 of the CAT28C256LI-12T is available in JEDEC approved 28-pin DIP package.
