X28HC256  
256k, 32k x 8-Bit  
Data Sheet  
September 21, 2011  
FN8108.3  
5V, Byte Alterable EEPROM  
Features  
The X28HC256 is a second generation high performance  
CMOS 32k x 8 EEPROM. It is fabricated with Intersil’s  
proprietary, textured poly floating gate technology, providing  
a highly reliable 5V only nonvolatile memory.  
• Access time: 70ns  
• Simple byte and page write  
- Single 5V supply  
- No external high voltages or VP-P control circuits  
- Self-timed  
The X28HC256 supports a 128-byte page write operation,  
effectively providing a 24µs/byte write cycle, and enabling  
the entire memory to be typically rewritten in less than 0.8  
seconds. The X28HC256 also features DATA Polling and  
Toggle Bit Polling, two methods of providing early end of  
write detection. The X28HC256 also supports the JEDEC  
standard Software Data Protection feature for protecting  
against inadvertent writes during power-up and power-down.  
- No erase before write  
- No complex programming algorithms  
- No overerase problem  
• Low power CMOS  
- Active: 60mA  
- Standby: 500µA  
Endurance for the X28HC256 is specified as a minimum  
1,000,000 write cycles per byte and an inherent data  
retention of 100 years.  
• Software data protection  
- Protects data against system level inadvertent writes  
• High speed page write capability  
• Highly reliable Direct Writecell  
- Endurance: 1,000,000 cycles  
- Data retention: 100 years  
• Early end of write detection  
- DATA polling  
- Toggle bit polling  
• Pb-free available (RoHS compliant)
