Freescale Semiconductor’s MFR4200 FlexRay controller is now available in production quantities.
By standardizing on the FlexRay protocol, automobile manufacturers can lower development and production costs; centralize and simplify the introduction of advanced high-speed electronic control systems; and increase overall vehicle stability and safety. The MFR4200 is designed to help automakers achieve these results by delivering 10 times more throughput than current controller area network (CAN) solutions and providing the fault tolerance and time-deterministic performance required for x-by-wire applications.
"As the number of embedded controllers for safety, reliability and comfort systems within the vehicle increases, a time-triggered communication system is critical," said Chris Webber, vice president of the Automotive Practice at Strategy Analytics. "With major automotive industry players committed to adopting the FlexRay protocol in the near future, the MFR4200 represents an important and timely investment for Freescale."
X-by-wire automotive subsystems (including braking, steering, suspension/reaction control, and throttle control) are expected to gradually replace most hydraulic lines and mechanical cables with wire-based networks, sensors and motors. The MFR4200 is designed to serve the needs of this market by providing a high level of communication bandwidth and deterministic, fault-tolerant data transmission.
This MFR4200 device is designed for chassis control, body electronics, and powertrain applications and offers integration with a wide range of microcontrollers. In addition, FlexRay complements the major in-vehicle networking standards (CAN, LIN, and MOST) by adding a high-speed protocol for the most demanding systems.
The MFR4200 features:
Bit rate up to a maximum of 10 Mbit/sec on each of two channels
Redundant for fault tolerance
Independent for 2x bandwidth
59 message buffers, each with a payload of up to 32 bytes of data
Each message buffer configurable as receive buffer, transmit buffer (single or double) or as part of the receive first in-first out (FIFO)
64-pin low-profile quad flat package (LQFP)

About the FlexRay Consortium
FlexRay founders Freescale, Philips, BMW and DaimlerChrysler have been working together since 2000 to help speed the adoption of FlexRay, a communications protocol designed to handle the growing number of digital elements that make up a 21st century automobile. Over the past two years, additional automotive companies, such as Bosch, General Motors, Ford, Volkswagen, Audi and Siemens VDO, have joined these leaders in an effort to make FlexRay the de facto standard for advanced applications in the automotive industry. Today, more than 80 companies from the automotive, semiconductor and software industries support the FlexRay standard. FlexRay-enabled vehicles are expected to hit the market in 2006.
