Description

The X28HC256 is a second generation high perfor- mance CMOS 32K x 8 E2 PROM. It is fabricated with Xicor's proprietary, textured poly floating gate tech- nology, providing a highly reliable 5 Volt only nonvolatile memory.

The X28HC256 supports a 128-byte page write opera- tion, effectively providing a 24s/byte write cycle and enabling the entire memory to be typically rewritten in less than 0.8 seconds. The X28HC256 also features DATA Polling and Toggle Bit Polling, two methods of providing early end of write detection. The X28HC256 also supports the JEDEC standard Software DATA Pro- tection feature for protecting against inadvertent writes during power-up and power-down.

Endurance for the X28HC256 is specified as a minimum 100,000 write cycles per byte and an inherent data retention of 100 years.
