Ramtron Qualifies 4-Kilobit F-RAM Memory Device to +125C for Intelligent Powertrain Applications

COLORADO SPRINGS, CO--(Marketwire - October 24, 2007) - Ramtron International Corporation (NASDAQ: RMTR), a leading developer and supplier of nonvolatile ferroelectric random access memory (F-RAM) and integrated semiconductor products, today expanded its line of +125 degrees Celsius F-RAM memory automotive devices. The FM25L04-GA -- a 4Kb (kilobit), 3V, serial peripheral interface (SPI) F-RAM -- is now Grade 1 AEC-Q100-specified to operate over the automotive temperature range of -40C to +125C and is guaranteed to retain data for 9,000 hours at that extreme temperature.

The FM25L04-GA is already designed into advanced powertrain systems where F-RAM is required to record data quickly and frequently so that the gearbox can continually adapt itself to changing driver behaviour and road conditions. F-RAM's No Delay™ writes and virtually unlimited endurance, coupled with a high-speed SPI interface, uniquely enables reliable data writes at maximum bus speed in this and other advanced automotive applications.

"Ramtron's F-RAM has been accepted as a mainstream memory technology in intelligent automotive applications in the passenger cab and under the hood," says Duncan Bennett, Ramtron International Strategic Marketing Manager. "Ramtron is growing its line of Grade 1 automotive parts to meet the emerging demands of automobile manufacturers worldwide."

About the FM25L04-GA

The FM25L04-GA is a 4Kb nonvolatile RAM with an industry-standard SPI that enhances the high-speed write capability of F-RAM technology. The device is a direct hardware replacement for equivalent EEPROMs, yet far superior because of its fast writes, virtually unlimited endurance, and low operating currents. The FM25L04-GA reads and writes at bus speeds up to 10MHz and boasts an advanced write protection scheme to prevent inadvertent writes and data corruption. It is guaranteed to retain data for 9,000 hours at +125C degrees as well as 17 years at +55C degrees and operates at 3 volts over the automotive temperature range. The FM25L04-GA is available in a "green" 8-pin SOIC package.

F-RAM in Intelligent Electronics

F-RAM's fast writes and high endurance make it an ideal memory for data collection and storage. As more sensors are designed into the car, more data needs to be collected. F-RAM NoDelay™ writes facilitates the collection of more data at higher frequencies, allowing intelligent automotive applications to act on the timeliest information available. F-RAM is designed into a multitude of sophisticated automotive electronics systems worldwide such as smart airbags, event data recorders, adaptive cruise control, powertrain, active steering, infotainment, diagnostics, anti-pinch/trap windows, etc. The current Grade 1 qualification will enable designers to benefit from F-RAM in systems throughout the car.
