Description
The FM24CL64 is a 64-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 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. The next bus
cycle may commence immediately without the need
for data polling. In addition, the product offers
virtually unlimited write endurance, orders of
magnitude more endurance than EEPROM. Also,
FRAM exhibits much lower power during writes than
EEPROM since write operations do not require an
internally elevated power supply voltage for write
circuits.
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°C to +85°C.
