Fujitsu Microelectronics America Inc. and Fujitsu Microelectronics Europe have introduced the MB91F465X, a new FlexRay controller designed for driver assistance applications.

Fujitsu said the controller is built around a high-speed FR 32bit CPU, 544Kbyte Flash and 32Kbyte RAM, with an internal clock speed of 100MHz and voltage range of 3-5.5V.

The FlexRay MCU will complement standard automotive buses, including CAN and 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 OS software, application software, development tools and support required for application development," said Gerhard Roos, director of the automotive business unit at 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."

The new Fujitsu controller will be available in engineering samples during the first quarter of 2007 in 100-pin QFP packaging. A multichip module version is available today for earlier development.
