Description
The FM24C16C 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 36 years
while eliminating the complexities, overhead, and
system level reliability problems caused by EEPROM
and other nonvolatile memories.
The FM24C16C 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 FM24C16C is capable of
supporting 1012 read/write cycles, or a million times
more write cycles than EEPROM.
These capabilities make the FM24C16C 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 the system to write
data more frequently, with less system overhead.
The FM24C16C provides substantial benefits to users
of serial EEPROM, and these benefits are available as
a hardware drop-in replacement. The FM24C16C 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.

Pin Description
Serial Data Address: This is a bi-directional data pin for the two-wire interface. It
employs an open-drain output and is intended to be wire-OR‟d with other devices on the
two-wire bus. The input buffer incorporates a Schmitt trigger for noise immunity and the
output driver includes slope control for falling edges. A pull-up resistor is required.
Serial Clock: The serial clock input for the two-wire interface. Data is clocked-out on
the falling edge and clocked-in on the rising edge.
Write Protect: When WP is high, the entire array is write-protected. When WP is low,
all addresses may be written. This pin is internally pulled down.
