Like all Xicor Programmable nonvolatile memories it is a 5V only device. The X2804C features the JEDEC approved pinout for byte-wide memories, compatible with industry standard RAMs, ROMs and EPROMs. The X2804C supports a 16-byte page write operation, typically providing a 300µs/byte write cycle, enabling the entire memory to be written in less than 640ms. The X2804C also features DATA Polling, a system software support scheme used to indicate the early completion of a write cycle. Xicor E2PROMs are designed and tested for applications requiring extended endurance. Inherent data retention is greater than 100 years.
