Description  
Pin Configuration  
The FM25040B is a 4-kilobit nonvolatile memory  
employing an advanced ferroelectric process. A  
ferroelectric random access memory or F-RAM is  
nonvolatile but operates in other respects as a RAM.  
It provides reliable data retention for 38 years while  
eliminating the complexities, overhead, and system  
level reliability problems caused by EEPROM and  
other nonvolatile memories.

The FM25040B performs write operations at bus  
speed. No write delays are incurred. Data is written to  
the memory array immediately after it has been  
successfully transferred to the device. The next bus  
cycle may commence immediately without the need  
for data polling. The FM25040B is capable of  
supporting up to 1012 read/write cycles, or a million  
times more write cycles than EEPROM.

These capabilities make the FM25040B 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.

replacement. The FM25040B uses the high-speed  
SPI bus, which enhances the high-speed write  
capability of F-RAM technology. The specifications  
are guaranteed over an industrial temperature range  
of -40°C to +85°C.  
This is a product that has fixed target specifications but are subject  
to change pending characterization results.
