Description
The FM25C160 is a 16-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.

Unlike serial EEPROMs, the FM25C160 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. In addition, the
product offers substantial write endurance compared
with other nonvolatile memories. The FM25C160 is
capable of supporting up to 1E10-read/write cycles --
far more than most systems will require from a serial
memory.
These capabilities make the FM25C160 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 FM25C160 provides substantial benefits to users
of serial EEPROM, in a hardware drop-in
replacement. The FM25C160 uses the high-speed SPI
bus, which enhances the high-speed write capability
of FRAM technology. It is guaranteed over an
industrial temperature range of -40°C to +85°C.
