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.
