Description
Pin Configuration
The FM24CL16B 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 38 years
while eliminating the complexities, overhead, and
system level reliability problems caused by EEPROM
and other nonvolatile memories.

The FM24CL16B performs write operations at bus
speed. No write delays are incurred. Data is written to
the memory array in the cycle after it has been
successfully transferred to the device. The next bus
cycle may commence immediately without the need
for data polling. The FM24CL16B is capable of
supporting 1014 read/write cycles, or a million times
more write cycles than EEPROM.

These capabilities make the FM24CL16B 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 a long write time
can cause data loss. The combination of features
allows the system to write data more frequently, with
less system overhead.

The FM24CL16B provides substantial benefits to
users of serial EEPROM, yet these benefits are
available in a hardware drop-in replacement. The
FM24CL16B is available in an industry standard 8-
pin SOIC package and uses a familiar two-wire
protocol. The specifications are guaranteed over the
industrial temperature range from -40°C to +85°C.
