Description  
Pin Configuration  
The FM24C256 is a 256-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.

The FM24C256 performs write operations at bus  
speed. No write delays are incurred. The next bus  
cycle may commence immediately without the need  
for data polling. In addition, the product offers write  
endurance orders of magnitude higher than  
EEPROM. Also, FRAM exhibits much lower power  
during writes than EEPROM since write operations  
do not require an internally elevated power supply  
voltage for write circuits.

These capabilities make the FM24C256 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  
combination of features allows more frequent data  
writing with less overhead for the system.
