256Kb EEPROM  
MYX28C32K8  
Features  
32K x 8 EEPROM - 5 Volt, Byte Alterable  
Access Time (ns): 70, 90, 120, 150  
Simple Byte and Page Write  
.Single 5V Supply  
Description  
No External High Voltages or VPP

Control Circuits  
The MYX28C32K8 is a high performance CMOS 32K x 8 E PROM. It is  
.Self-Timed  
fabricated with a textured poly floating gate technology, providing a highly  
reliable 5 Volt only nonvolatile memory.  
No Erase Before Write  
No Complex Programming  
Algorithms  
The MYX28C32K8 supports a 128-byte page write operation, effectively  
providing a 24ms/byte write cycle and enabling the entire memory to be  
typically rewritten in less than 0.8 seconds.The MYX28C32K8 also features  
DATA Polling and Toggle Bit Polling, two methods of providing early end  
of write detection. The MYX28C32K8 also supports the JEDEC standard  
Software Data Protection feature for protecting against inadvertent writes  
during power-up and power-down.  
No Overerase Problem  
Low Power CMOS:  
.Active: 60mA  
.Standby: 500mA  
Software Data Protection  
.Protects Data Against System Level  
Inadvertent Writes  
High Speed Page Write Capability  
Highly Reliable Direct Write™ Cell  
.Endurance: 100,000 Write Cycles  
.Data Retention: 100 Years  
Early End of Write Detection  
.DATA Polling  
Endurance for the MYX28C32K8 is specified as a minimum 100,000 write  
cycles per byte and an inherent data retention of 100 years.
