Description

The FM25V02 is a 256-kilobit nonvolatile memory employing an advanced ferroelectric process. A ferroelectric random access memory or F-RAM 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 Serial Flash and other nonvolatile memories.

Unlike Serial Flash, the FM25V02 performs write operations at bus speed. No write delays are incurred. Data is written to the memory array immediately after it has been transferred to the device. The next bus cycle may commence without the need for data polling. The product offers very high write endurance, orders of magnitude more endurance than Serial Flash. Also, F-RAM exhibits lower power consumption than Serial Flash.

These capabilities make the FM25V02 ideal for nonvolatile memory applications requiring frequent or rapid writes or low power operation. Examples range from data collection, where the number of write cycles may be critical, to demanding industrial controls where the long write time of Serial Flash can cause data loss.

The FM25V02 provides substantial benefits to users of Serial Flash as a hardware drop-in replacement. The devices use the high-speed SPI bus, which enhances the high-speed write capability of F-RAM technology. The FM25VN02 is offered with a unique serial number that is read-only and can be used to identify a board or system. Both devices incorporate a read-only Device ID that allows the host to determine the manufacturer, product density, and product revision. The devices are guaranteed over an industrial temperature range of -40°C to +85°C.

Absolute Maximum Ratings

Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only, and the functional operation of the device at these or any other conditions above those listed in the operational section of this specification is not implied. Exposure to absolute maximum ratings conditions for extended periods may affect device reliability.
