16K/64K/128K  
MPSEEPROM  
X84160/640/128  
Advanced MPS™ Micro Port Saver EEPROM with Block Lock™ Protection  
FEATURES  
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 volt-  
age, and small package size while releasing I/Os for  
more important uses.  
• Up to 15MHz data transfer rate  
• 20ns Read Access Time  
• Direct Interface to Microprocessors and  
Microcontrollers  
—Eliminates I/O port requirements  
—No interface glue logic required  
—Eliminates need for parallel to serial converters  
• Low Power CMOS  
—1.8V–3.6V, 2.5V–5.5V and 5V 10% Versions  
—Standby Current Less than 1µA  
—Active Current Less than 1mA  
• Byte or Page Write Capable  
The µPort Saver memory outputs data within 20ns of an  
active read signal. This is less than the read access time  
of most hosts and provides “no-wait-state” operation.  
This prevents bottlenecks on the bus. With rates to  
15MHz, the µPort Saver supplies data faster than  
required by most host read cycle specifications. This  
eliminates the need for software NOPs.  
—32-Byte Page Write Mode  
• New Programmable Block Lock™ Protection  
—Software Write Protection  
—Programmable Hardware Write Protection  
• Block Lock (0, 1/4, 1/2, or all of the array)  
• Typical Nonvolatile Write Cycle Time: 3ms  
• High Reliability  
—100,000 Endurance Cycles  
—Guaranteed Data Retention: 100Years  
• Small Package Options  
—8-Lead Mini-DIP Package  
—8, 14-Lead SOIC Packages  
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.  
The X84160/640/128 provide additional data security  
features through Block Lock and programmable Hard-  
ware Write Protection. These allow some or all of the  
array to be write protected by software command or by  
hardware. System Configuration, Company ID, calibra-  
tion information, or other critical data can be secured  
against unexpected or inadvertent program operations,  
leaving the remainder of the memory available for the  
system or user access  
—8, 20, 28-Lead TSSOP Packages  
—8-Lead XBGA Packages  
A Write Protect (WP) pin prevents inadvertent writes to  
the memory.  
DESCRIPTION  
The µPort Saver memories need no serial ports or spe-  
cial hardware and connect to the processor memory bus.  
Replacing bytewide data memory, the µPort Saver uses  
Xicor EEPROMs are designed and tested for applica-  
tions requiring extended endurance. Inherent data reten-  
tion is greater than 100 years.
