Product Summary

The X28HC256P-12 is a second generation high performance CMOS 32k x 8 EEPROM. The X28HC256P-12 is fabricated with Intersil’s proprietary, textured poly floating gate technology, providing a highly reliable 5V only nonvolatile memory. The X28HC256P-12 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 X28HC256P-12 also features DATA Polling and Toggle Bit Polling, two methods of providing early end of write detection. It also supports the JEDEC standard Software Data Protection feature for protecting against inadvertent writes during power-up and power-down.
