X28HC256  
®
256K, 32K x 8 Bit  
Data Sheet  
June 1, 2005  
FN8108.0  
DESCRIPTION  
5 Volt, Byte Alterable EEPROM  
The X28HC256 is a second generation high perfor-  
mance CMOS 32K x 8 EEPROM. It is fabricated with  
Intersil’s proprietary, textured poly floating gate tech-  
nology, providing a highly reliable 5 Volt only nonvola-  
tile memory.  
FEATURES  
• Access time: 70ns  
• Simple byte and page write  
—Single 5V supply  
No external high voltages or V control circuits  
—Self-timed  
—No erase before write  
—No complex programming algorithms  
—No overerase problem  
• Low power CMOS  
—Active: 60mA  
—Standby: 500µA  
• Software data protection  
—Protects data against system level inadvertent  
writes  
PP  
The X28HC256 supports a 128-byte page write opera-  
tion, 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 Pro-  
tection feature for protecting against inadvertent writes  
during power-up and power-down.  
Endurance for the X28HC256 is specified as a mini-  
mum 1,000,000 write cycles per byte and an inherent  
data retention of 100 years.  
• High speed page write capability  
• Highly reliable Direct Write cell  
—Endurance: 1,000,000 cycles  
—Data retention: 100 years  
• Early end of write detection  
—DATA polling  
—Toggle bit polling
