FM24CL64B
64Kb Serial 3V F-RAM Memory
Features
64K bit Ferroelectric Nonvolatile RAM
Fast Two-wire Serial Interface
Description
The FM24CL64B is a 64-kilobit nonvolatile memory
employing an advanced ferroelectric process. A
ferroelectric random access memory or F-RAM 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
EEPROM and other nonvolatile memories.
The FM24CL64B 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 FM24CL64B is capable of
supporting 10
more write cycles than EEPROM.
These capabilities make the FM24CL64B 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 more frequent data
writing with less overhead for the system.
The FM24CL64B provides substantial benefits to
users of serial EEPROM, yet these benefits are
available in a hardware drop-in replacement. The
FM24CL64B is available in an industry standard 8-
pin SOIC package and uses a familiar two-wire
protocol. The specifications are guaranteed over an
industrial temperature range of -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.
