Functional Description
The FM24C16B is a 16-Kbit nonvolatile memory employing an
advanced ferroelectric process. A ferroelectric random access
memory or F-RAM is nonvolatile and performs reads and writes
similar to a RAM. It provides reliable data retention for 151 years
while eliminating the complexities, overhead, and system-level
reliability problems caused by EEPROM and other nonvolatile
memories.
Unlike EEPROM, the FM24C16B performs write operations at
bus speed. No write delays are incurred. Data is written to the
memory array immediately after each byte is successfully
transferred to the device. The next bus cycle can commence
without the need for data polling. In addition, the product offers
substantial write endurance compared with other nonvolatile
memories. Also, F-RAM exhibits much lower power during writes
than EEPROM since write operations do not require an internally
elevated power supply voltage for write circuits. The FM24C16B
is capable of supporting 1014 read/write cycles, or 100 million
times more write cycles than EEPROM.
These capabilities make the FM24C16B ideal for nonvolatile
memory applications, requiring frequent or rapid writes.
Examples range from data logging, 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.
The FM24C16B provides substantial benefits to users of serial
(I2C) EEPROM as a hardware drop-in replacement. The device
specifications are guaranteed over an industrial temperature
range of –40 C to +85 C.

Description
Input/Output Serial Data/Address. This is a bi-directional pin for the I2C interface. It is open-drain and is intended
to be wire-AND’d with other devices on the I2C bus. The input buffer incorporates a Schmitt trigger for
noise immunity and the output driver includes slope control for falling edges. An external pull-up resistor
is required.
Input
Serial Clock. The serial clock pin for the I2C interface. Data is clocked out of the device on the falling
edge, and into the device on the rising edge.
Input
Write Protect. When tied to VDD, addresses in the entire memory map will be write-protected. When
WP is connected to ground, all addresses are write enabled. This pin is pulled down internally.
Power supply Ground for the device. Must be connected to the ground of the system.
Power supply Power supply input to the device.
