Quick Detail:
5 Volt, Byte Alterable E2PROM
Description:
The X28HC256 is a second generation high performance CMOS 32K x 8 E2PROM. It is fabricated with Xicor’s proprietary, textured poly floating gate technology, providing a highly reliable 5 Volt only nonvolatile memory.
The X28HC256 supports a 128-byte page write operation, effectively providing a 24µs/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 Protection 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.
