Very Fast Serial Peripheral Interface - SPI
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 45 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
immediately after it has been successfully transferred
to the device. The next bus cycle may commence
immediately.
substantial write endurance compared with other
nonvolatile memories. The FM25C160 is capable of
supporting up to 10
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
replacement. The FM25C160 uses the high-speed SPI
bus, which enhances the high-speed write capability
of FRAM technology. 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.
