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 pinto for byte-wide mem-  
ories, compatible with industry standard RAMs.  
PP  
—40mA active current max.  
—200µA standby current max.  
• Fast write cycle times  
—64-byte page write operation  
—Byte or page write cycle: 2ms typical  
—Complete memory rewrite: 0.25 sec. typical  
—Effective byte write cycle time: 32µs typical  
• Software data protection  
• End of write detection  
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.  
—DATA polling  
—Toggle bit  
Intersil EEPROMs are designed and tested for appli-  
cations requiring extended endurance. Inherent data  
retention is greater than 100 years.
