64k, 8k x 8-Bit 5 Volt, Byte Alterable EEPROM

The X28HC64 is an 8k x 8 EEPROM, fabricated with Intersil’s proprietary, high performance, floating gate CMOS technology. Like all Intersil programmable nonvolatile memories, the X28HC64 is a 5V only device. It features the JEDEC approved pinout for byte-wide memories, compatible with industry standard RAMs.
