DESCRIPTION  
The X28HC64 is an 8K x 8 E2PROM, fabricated with  
Xicor’s proprietary, high performance, floating gate  
CMOS technology. Like all Xicor programmable non-  
volatilememoriestheX28HC64isa5Vonlydevice. The  
X28HC64featurestheJEDECapprovedpinoutforbyte-  
widememories,compatiblewithindustrystandardRAMs.  
—No Erase Before Write  
—No Complex Programming Algorithms  
—No Overerase Problem  
Low Power CMOS  
—40 mA Active Current Max.  
—200 µA 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,  
effectivelyprovidinga32µs/bytewritecycleandenabling  
the entire memory to be typically written in 0.25 seconds.  
TheX28HC64alsofeaturesDATA PollingandToggleBit  
Polling, two methods providing early end of write detec-  
tion. In addition, the X28HC64 includes a user-optional  
software data protection mode that further enhances  
Xicor’s hardware write protect capability.  
DATA Polling  
Xicor E2PROMs are designed and tested for applica-  
tions requiring extended endurance. Inherent data re-  
tention is greater than 100 years.
