Description  
Pin Configuration  
The FM25040 is a 4-kilobit nonvolatile memory  
employing an advanced ferroelectric process. A  
ferroelectric random access memory or FRAM is  
nonvolatile but operates in other respects as a RAM.  
It provides reliable data retention for 10 years while  
eliminating the complexities, overhead, and system  
level reliability problems caused by EEPROM and  
other nonvolatile memories.

Unlike serial EEPROMs, the FM25040 performs  
write operations at bus speed. No write delays are  
incurred. Data is written to the memory array mere  
hundreds of nanoseconds after it has been  
successfully transferred to the device. The next bus  
cycle may commence immediately. In addition the  
product offers substantial write endurance compared  
with other nonvolatile memories. The FM25040 is  
capable of supporting up to 1E10 read/write cycles --  
far more than most systems will require from a serial  
memory.

These capabilities make the FM25040 ideal for  
nonvolatile memory applications requiring frequent  
or rapid writes. Examples range from data collection,  
where the number of write cycles may be critical, to  
demanding industrial controls where the long write  
time of EEPROM can cause data loss.

The FM25040 provides substantial benefits to users  
of serial EEPROM, in  
a
hardware drop-in  
replacement. The FM25040 uses the high-speed SPI  
bus which enhances the high-speed write capability of  
FRAM technology. It is guaranteed over an industrial  
temperature range of -40°C to +85°C.
