The X28C64 is an 8K x 8 E PROM, fabricated with Xicor's proprietary, high performance, floating gate CMOS technology. Like all Xicor programmable non-volatile memories the X28C64 is a 5V only device. The X28C64 features the JEDEC approved pinout for byte- wide memories, compatible with industry standard RAMs.
The X28C64 supports a 64-byte page write operation, effectively providing a 78s/byte write cycle and en- abling the entire memory to be typically written in 0.625 seconds. The X28C64 also features DATA and Toggle Bit Polling, a system software support scheme used to indicate the early completion of a write cycle. In addition, the X28C64 includes a user-optional software data protection mode that further enhances Xicor's hardware write protect capability.
Xicor E PROMs are designed and tested for applications requiring extended endurance. Inherent data retention is greater than 100 years.
