FEATURES
DESCRIPTION
The X28C256 is an 32K x 8 E2PROM, fabricated with Xicor’s proprietary, high performance, floating gate CMOS technology. Like all Xicor programmable nonvolatile memories the X28C256 is a 5V only device. The X28C256 features the JEDEC approved pinout for bytewide memories, compatible with industry standard RAMs. The X28C256 supports a 64-byte page write operation, effectively providing a 78µs/byte write cycle and enabling 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.
