The FM25L16 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 45 years
while eliminating the complexities, overhead, and
system level reliability problems caused by
EEPROM and other nonvolatile memories.
Unlike serial EEPROMs, the FM25L16 performs
write operations at bus speed. No write delays are
incurred. Data is written to the memory array
immediately after each byte has been transferred to
the device. The next bus cycle may commence
without the need for data polling. The product offers
virtually unlimited write endurance, orders of
magnitude more endurance than EEPROM. FRAM
also exhibits much lower power during writes than
EEPROM.
These capabilities make the FM25L16 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 FM25L16 provides substantial benefits to users
of serial EEPROM as a hardware drop-in
replacement. The FM25L16 uses the high-speed SPI
bus, which enhances the high-speed write capability
of FRAM technology. Device specifications are
guaranteed over an industrial temperature range of
-40°C to +85°C.
