Description
The FM24CL64 is a 64-kilobit nonvolatile memory
employing an advanced ferroelectric process. A
ferroelectric random access memory or FRAM is
nonvolatile but operates in other respects as a RAM.
It provides reliable data retention for 10 years while
eliminating the complexities, overhead, and system
level reliability problems caused by EEPROM and
other nonvolatile memories.
The FM24CL64 performs write operations at bus
speed. No write delays are incurred. Data is written to
the memory array mere hundreds of nanoseconds
after it has been successfully transferred to the
device. The next bus cycle may commence
immediately. Fast-write time and unlimited
read/write endurance make it superior to other types
of nonvolatile memory and a good substitute for
ordinary SRAM
These capabilities make the FM24CL64 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 FM24CL64 provides substantial benefits to users
of serial EEPROM, yet these benefits are available in
a hardware drop-in replacement. The FM24CL64 is
provided in industry standard 8-pin surface mount
package using a familiar two-wire protocol. It is
guaranteed over an industrial temperature range of
-40擄C to +85擄C.
