The X28HC256 is a second generation high performance CMOS 32k x 8 EEPROM. It is fabricated with Intersil’s proprietary, textured poly floating gate technology, providing a highly reliable 5V 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 0.8s. The X28HC256 also features span style="text-decorati
Endurance for the X28HC256 is specified as a minimum 100,000 write cycles per byte and an inherent data retention of 100 years
