Datasheet
FM24C16A
16Kb FRAM Serial Memory
Features
16K bit Ferroelectric Nonvolatile RAM
Fast Two-wire Serial Interface
Description
The FM24C16A 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 over 45
years while eliminating the complexities, overhead,
and system level reliability problems caused by
EEPROM and other nonvolatile memories.
Unlike serial EEPROMs, the FM24C16A performs
write operations at bus speed. No write delays are
incurred. The next bus cycle may commence
immediately without the need for data polling. The
FM24C16A is capable of supporting 10
cycles, or a million times more write cycles than
EEPROM.
These capabilities make the FM24C16A 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 FM24C16A provides substantial benefits to users
of serial EEPROM, and these benefits are available as
a hardware drop-in replacement. The FM24C16A is
available in an industry standard 8-pin SOIC and uses
a
guaranteed over the industrial temperature range from
-40°C to +85°C.
This product conforms to specifications per the terms of the Ramtron
standard warranty. The product has completed Ramtron’s internal
qualification testing and has reached production status.
