The FM25L512 device from Ramtron International Corp. is a 512Kbit 3V nonvolatile FRAM device with a high-speed serial peripheral interface.

According to Mike Alwais, Ramtron VP of marketing, the FM25L512 provides increased data collection and storage capacity in a tiny, 8-pin package, cutting costs and board space in a range of applications from multifunction printers to industrial motor controllers. "System designers can increase data collection capacity without increasing board space in next-generation printer and motor control designs."

A direct hardware replacement for equivalent EEPROMs, the FM25L512 offers NoDelay reads, writes at bus speeds of up to 20MHz, 10-year data retention, virtually unlimited read/write endurance and low operating currents. The device operates from 3V to 3.6V and is rated over the industrial temperature range of -40C to 85C.

The FM25L512 outperforms alternative nonvolatile memory solutions for applications that require frequent and rapid writes and/or low power operation. These applications range from advanced data collection, in which the number of write cycles is critical, to demanding industrial controls, in which long write delays and limited endurance can cause data loss. Unlike serial EEPROMs, the FM25L512 performs write operations at bus speed and exhibits much lower power consumption.

Samples of the FM25L512 are currently available in an 8-pin "Green"/RoHS TDFN package that is footprint-compatible with the SOIC-8 package, with pricing starting at $7.61 in quantities of 10,000.
