Freescale Drives Toward the Autonomous Vehicle with FlexRay(TM) Products; FlexRay 2.1 Compliant Controllers Help Automotive Manufacturers Make Intelligent Automobiles a Reality

As the leading supplier of microcontrollers to the automotiveindustry and a founding member of the FlexRay Consortium, Freescale ispositioned to help car manufacturers network in-car systems to makesmarter, integrated active safety systems a reality.

The MC9S12XFR is Freescale's first microcontroller to integrate aFlexRay module with the 16-bit S12X core. By introducing the 9S12XFR &MFR4300 FlexRay node controller, Freescale has taken a significantstep forward in providing the key semiconductor components for nextgeneration X-by-wire subsystems.

"The automotive market is showing intense interest in FlexRay andis keen to see new technology developments supporting this protocol,"said Chris Webber, vice president of the Automotive Practice atStrategy Analytics. "At this stage of the market development for theFlexRay protocol it is important that designers have the flexibilityoffered by components such as the ones announced by Freescale. Asautomobile makers continue to innovate in advanced safety, comfort,performance and infotainment features, FlexRay will help to make theseconcepts a reality."

The FlexRay protocol provides higher data rates and faulttolerance required for advanced control systems combining multiplesensors, actuators and electronic control units. Core member companiesof the FlexRay Consortium include BMW, Bosch, DaimlerChrysler,Freescale, General Motors, Philips and Volkswagen. Other leadingJapan-based manufacturers such as Honda, Nissan and Toyota have joinedthe consortium as premium associate members, adding momentum to thegrowing acceptance of the FlexRay protocol.

"FlexRay is rapidly becoming the de facto standard for high-speedin-vehicle networking," said Juergen Weyer, vice president and generalmanager of Freescale's transportation business in Europe. "As afounding member of the FlexRay Consortium, Freescale has made it apriority to proliferate this network protocol. The combinedavailability of integrated and stand alone products gives Freescalethe opportunity to offer customers a choice with FlexRay devices,which was previously unattainable within the industry."

The 9S12XFR and MFR4300 devices are ideal for chassis control,body electronics and powertrain applications where increasedfunctionality and on-board diagnostics are required. The FlexRaydevices complement major in-vehicle networking standards (CAN, LIN andMOST) by adding a high-speed protocol for the most demanding systems.

About the FlexRay Consortium

FlexRay founders Freescale, Philips, BMW and DaimlerChrysler havebeen working together since 2000 to help speed the adoption ofFlexRay, a communications protocol designed to handle the growingnumber of digital elements that make up a 21st century automobile.Over the past two years, additional automotive companies, such asBosch, General Motors, Ford, Volkswagen, Audi and Siemens VDO, havejoined these leaders in an effort to make FlexRay the de factostandard for advanced applications in the automotive industry. Today,more than 80 companies from the automotive, semiconductor and softwareindustries support the FlexRay standard. FlexRay-enabled vehicles areexpected to hit the market in 2006.
