Product Summary

The X28HC64 is an 8K x 8 E2PROM, fabricated with Xicor proprietary, high performance, floating gate CMOS technology. Like all Xicor programmable nonvolatile memories the X28HC64 is a 5V only device. The X28HC64 features the JEDEC approved pinout for bytewide memories, compatible with industry standard RAMs. It supports a 64-byte page write operation, effectively providing a 32μs/byte write cycle and enabling the entire memory to be typically written in 0.25 seconds.
