Description
The FM24C04 is a 4-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 FM24C04 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 FM24C04 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 FM24C04 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 mre frequent data
writing with less overhead for the system.
The FM24C04 provides substantial benefits to users
of serial EEPROM, yet these benefits are available in a
hardware drop-in replacement. The FM24C04 is
provided in industry standard 8-pin packages using a
familiar two-wire protocol. They are guaranteed over
an industrial temperature range of -40°C to +85°C.
