serial number that is read-only and can be used to  
identify a board or system. Both devices incorporate  
a read-only Device ID that allows the host to  
determine the manufacturer, product density, and  
product revision. The devices are guaranteed over an  
industrial temperature range of -40°C to +85°C.  
Description  
The FM25V02 is a 256-kilobit nonvolatile memory  
employing an advanced ferroelectric process. A  
ferroelectric random access memory or F-RAM is  
nonvolatile and performs reads and writes like a  
RAM. It provides reliable data retention for 10 years  
while eliminating the complexities, overhead, and  
system level reliability problems caused by Serial  
Flash and other nonvolatile memories.

Unlike Serial Flash, the FM25V02 performs write  
operations at bus speed. No write delays are incurred.  
Data is written to the memory array immediately  
after it has been transferred to the device. The next  
bus cycle may commence without the need for data  
polling. The product offers very high write  
endurance, orders of magnitude more endurance than  
Serial Flash. Also, F-RAM exhibits lower power  
consumption than Serial Flash.

These capabilities make the FM25V02 ideal for  
nonvolatile memory applications requiring frequent  
or rapid writes or low power operation. Examples  
range from data collection, where the number of  
write cycles may be critical, to demanding industrial  
controls where the long write time of Serial Flash can  
cause data loss.

The FM25V02 provides substantial benefits to users  
of Serial Flash as a hardware drop-in replacement.  
The devices use the high-speed SPI bus, which  
enhances the high-speed write capability of F-RAM

This is a product in the pre-production phase of development. Device  
characterization is complete and Ramtron does not expect to change the  
specifications. Ramtron will issue a Product Change Notice if any  
specification changes are made.
