High-speed SPI interface

Ramtron International Corporation has launched the FM25L512, a 512 kilobit, 3-volt non-volatile FRAM device with a high-speed serial peripheral interface (SPI).

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 multi-function printers to industrial motor controllers.

Ramtron’s FM25L512 is a 512 kilobit non-volatile RAM with an industry-compatible SPI interface that leverages the high-speed write capability of FRAM technology. A direct hardware replacement for equivalent EEPROMs, only better, 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 3.0 to 3.6 volts and is rated over the industrial temperature range of -40 degrees C to +85 degrees C.

The FM25L512 is claimed to outperform alternative non-volatile 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.
