June 27, 2016 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.
The X28HC64 supports a 64-byte page write operation, effectively
providing a 32Вµs/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 applications
requiring extended endurance. Inherent data retention is
greater than 100 years. Features 70ns access time Simple byte and page write
-Single 5V supply
-No external high voltages or VP-P control circuits
-Self-timed …
