X28HC64 General Description

      The X28HC64 is an 8K x 8 E² PROM, fabricated with Xicor°Os proprietary, high performance, floating gat CMOS technology. Like all Xicor programmable non volatile memories the X28HC64 is a 5V only device. The X28HC64 features the JEDEC approved pinout for byte wide memories, compatible with industry standard RAMs.

     The X28HC64 supports a 64-byte page write operation, effectively providing a 32s/byte write cycle and enabling the entire memory to be typically written in 0.25 seconds. The X28HC64 also features DATAPolling and Toggle Bit Polling, two methods providing early end of write detection. In addition, the X28HC64 includes a user-optional software data protection mode that further enhances Xicor°Os hardware write protect capability

      Xicor E² PROMs are designed and tested for applications requiring extended endurance. Inherent data retention is greater than 100 years.
