Description  
Pin Configuration  
The FM25L16 is a 16-kilobit nonvolatile memory  
employing an advanced ferroelectric process. A  
ferroelectric random access memory or FRAM is  
nonvolatile and performs reads and writes like a  
RAM. It provides reliable data retention for 45 years  
while eliminating the complexities, overhead, and  
system level reliability problems caused by  
EEPROM and other nonvolatile memories.

Unlike serial EEPROMs, the FM25L16 performs  
write operations at bus speed. No write delays are  
incurred. Data is written to the memory array  
immediately after each byte has been transferred to  
the device. The next bus cycle may commence  
without the need for data polling. The product offers  
virtually unlimited write endurance, orders of  
magnitude more endurance than EEPROM. FRAM  
also exhibits much lower power during writes than  
EEPROM.

These capabilities make the FM25L16 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 FM25L16 provides substantial benefits to users  
of serial EEPROM as  
a
hardware drop-in  
replacement. The FM25L16 uses the high-speed SPI  
bus, which enhances the high-speed write capability  
of FRAM technology. Device specifications are  
guaranteed over an industrial temperature range of  
-40°C to +85°C.
