• High reliability
• JEDEC approved byte-wide pin out
• Pb-free plus anneal available (RoHS compliant)
DESCRIPTION
The X28HC64 is an 8K x 8 EEPROM, fabricated with
Intersil’s proprietary, high performance, floating gate
CMOS technology. Like all Intersil programmable non-
volatile memories, the X28HC64 is a 5V only device. It
features the JEDEC approved pinout for byte-wide
memories, compatible with industry standard RAMs.
The X28HC64 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. The X28HC64 also features DATA Polling and
Toggle Bit Polling, two methods providing early end of
write detection. In addition, the X28HC64 includes a
user-optional software data protection mode that further
enhances Intersil’s hardware write protect capability.
Intersil EEPROMs are designed and tested for appli-
cations requiring extended endurance. Inherent data
retention is greater than 100 years.
