1 / 24 page X28C256 1 5 Volt, Byte Alterable E2PROM © Xicor, Inc. 1991, 1995 Patents Pending Characteristics subject to change without notice 3855-1.9 8/1/97 T1/C0/D8 EW DESCRIPTION The X28C256 is an 32K x 8 E2PROM, fabricated with Xicor’s proprietary, high performance, floating gate CMOS technology. Like all Xicor programmable non- volatile memories the X28C256 is a 5V only device. The X28C256 features the JEDEC approved pinout for byte- wide memories, compatible with industry standard RAMs. The X28C256 supports a 64-byte page write operation, effectively providing a 78 µs/byte write cycle and en- abling the entire memory to be typically written in less than 2.5 seconds. The X28C256 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 X28C256 includes a user-optional software data protection mode that further enhances Xicor’s hardware write protect capability. Xicor E2PROMs are designed and tested for applica- tions requiring extended endurance. Inherent data re- tention is greater than 100 years.
