FM24C16B
16Kb Serial 5V F-RAM Memory
Features
16K bit Ferroelectric Nonvolatile RAM
Fast Two-wire Serial Interface
Description
The FM24C16B 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 FM24C16B 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 FM24C16B is capable of
supporting 10
more write cycles than EEPROM.
These capabilities make the FM24C16B 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 FM24C16B provides substantial benefits to users
of serial EEPROM, and these benefits are available as
a hardware drop-in replacement. The FM24C16B 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.
This is a product that has fixed target specifications but are subject
to change pending characterization results.
