The X28HC256 is a second generaTIon high performanceCMOS 32k x 8 EEPROM. It is fabricated with Intersil’sproprietary, textured poly floaTIng gate technology, providinga highly reliable 5V only nonvolaTIle memory.The X28HC256 supports a 128-byte page write operaTIon,effectively providing a 24μs/byte write cycle, and enablingthe entire memory to be typically rewritten in less than 0.8seconds. The X28HC256 also features DATA Polling andToggle Bit Polling, two methods of providing early end ofwrite detection. The X28HC256 also supports the JEDECstandard Software Data Protection feature for protectingagainst inadvertent writes during power-up and power-down.Endurance for the X28HC256 is specified as a minimum1,000,000 write cycles per byte and an inherent dataretention of 100 years.
