X28C64  
5 Volt, Byte Alterable E2PROM  
DESCRIPTION  
8K x 8 Bit  
FEATURES  
150ns Access Time  
The X28C64 is an 8K x 8 E2PROM, fabricated with  
Xicor’s proprietary, high performance, floating gate  
CMOS technology. Like all Xicor programmable non-  
volatile memories the X28C64 is a 5V only device. The  
X28C64 features the JEDEC approved pinout for byte-  
widememories,compatiblewithindustrystandardRAMs.  
Simple Byte and Page Write  
—Single 5V Supply  
—No External High Voltages or VPP Control  
Circuits  
—Self-Timed  
—No Erase Before Write  
—No Complex Programming Algorithms  
—No Overerase Problem  
The X28C64 supports a 64-byte page write operation,  
effectively providing a 78µs/byte write cycle and en-  
abling the entire memory to be typically written in 0.625  
seconds. The X28C64 also features DATA and Toggle  
Bit Polling, a system software support scheme used to  
indicate the early completion of a write cycle. In addi-  
tion, theX28C64includesauser-optionalsoftwaredata  
protection mode that further enhances Xicor’s hard-  
ware write protect capability.  
Low Power CMOS  
—60mA Active Current Max.  
—200µA Standby Current Max.  
Fast Write Cycle Times  
—64 Byte Page Write Operation  
—Byte or Page Write Cycle: 5ms Typical  
—Complete Memory Rewrite: 0.625 sec. Typical  
—Effective Byte Write Cycle Time: 78µs Typical  
Software Data Protection  
End of Write Detection  
Xicor E2PROMs are designed and tested for applica-  
tions requiring extended endurance. Inherent data re-  
tention is greater than 100 years.  
DATA Polling  
—Toggle Bit  
High Reliability  
—Endurance: 100,000 Cycles  
—Data Retention: 100 Years
