µPort Saver EEPROM  
DESCRIPTION  
FEATURES  
• Up to 10MHz data transfer rate at 5V operator  
• 25ns Read Access Time  
• Direct interface to microprocessors and micro-  
controllers  
—Eliminates I/O port requirements  
—No interface glue logic required  
Eliminates need for parallel to serial converters  
• Low power CMOS  
The µPort Saver memories need no serial ports or  
special hardware and connect to the processor mem-  
ory bus. Replacing bytewide data memory, the µPort  
Saver uses bytewide memory control functions, takes  
a fraction of the board space and consumes much less  
power. Replacing serial memories, the µPort Saver  
provides all the serial benefits, such as low cost, low  
power, low voltage, and small package size, while  
releasing I/Os for more important uses.  
—2.5V–5.5V version  
—Standby current less than 1µA  
—Active current less than 1mA  
• Byte or page write capable  
—32-byte page write mode  
• Typical nonvolatile write cycle time: 2ms  
• High reliability  
—100,000 endurance cycles  
—Guaranteed data retention: 100 years  
• Small packages options  
The µPort Saver memory outputs data within 25ns of  
an active read signal. This is less than the read access  
time of most hosts and provides “no-wait-state” opera-  
tion. This prevents bottlenecks on the bus. With rates  
to 10MHz, the µPort Saver supplies data faster than  
required by most host read cycle specifications. This  
eliminates the need for software NOPs.  
The µPort Saver memories communicate over one line  
of the data bus using a sequence of standard bus read  
and write operations. This “bit serial” interface allows  
the µPort Saver to work well in 8-bit, 16-bit, 32-bit, and  
64-bit systems.  
—8-lead XBGA package  
—14-lead SOIC package  
—28-lead TSSOP package  
A Write Protect (WP) pin prevents inadvertent writes to  
the memory.  
Xicor EEPROMs are designed and tested for applica-  
tions requiring extended endurance. Inherent data  
retention is greater than 100 years.
