Fujitsu Microelectronics America Inc. (FMA) and Fujitsu Microelectronics Europe has introduced a new FlexRay controller, the MB91F465X, at a press conference at Convergence 2006 in Detroit.

The new Fujitsu controller will be available in engineering samples during the first quarter of 2007 in 100-pin QFP packaging. Designed for driver assistance applications, the controller is built around a Fujitsu high-speed FR 32bit CPU, 544KB Flash and 32KB RAM, with an internal clock speed of 100MHz and voltage range of 3V to 5.5V. A multi-chip module version is available now for earlier development.

The FlexRay MCU will complement standard automotive buses, including the Controller Area Network (CAN) and Local Interconnect Network (LIN). FlexRay-based technology provides time-triggered communication at rates 10 times the throughput of CAN, and is expected to gradually replace CAN as automakers and their suppliers adopt x-by-wire solutions. The initial use of FlexRay will be in non-safety-critical applications in chassis and body control such as automatic transmission, electrical power steering, lane changing and parking management assistance, and vehicle stability. Future applications will be in safety-critical systems.

"Our 'FlexRay Made Easy' program includes the hardware, driver and operating systems software, application software, development tools, and support required for application development," said Dr. Gerhard Roos, director of the Automotive Business Unit, Fujitsu Microelectronics Europe. "This FlexRay MCU represents the latest step forward in our program to deliver complete FlexRay solutions as this important new communications standard emerges in the automotive market."
