DESCRIPTION
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.
