Adura Systems Adopts Freescale’s FlexRay Automotive Microcontroller Technology for MESA

Adura Systems, Inc., developer of the MESA (Modular, Electronic, Scalable Architecture) electric powertrain for medium and large vehicles (earlier post), has selected Freescale Semiconductor’s FlexRay automotive microcontroller (MCU) technology for high-speed in-vehicle networking.

Adura is incorporating Freescale’s S12XF MCU with integrated FlexRay technology into the MESA powertrain, which offers up to 100 miles of pure electric range in mass transportation buses.

Developing 100 mile pure electric range powertrains requires very sophisticated electronics, software and a high-bandwidth communications and control layer. Adura selected FlexRay technology because it is one of the only automotive networking systems able to handle safety-critical communications and control. Also, FlexRay provides the communications layer upon which Adura’s network, DEFT-net (Deterministic, Extensible, Fault-Tolerant Network), is built. Adura’s DEFT-net provides accurate data delivery, distributed control, fault detection and tolerance, and on-the-fly reconfiguration.

FlexRay’ determinism and high speed, combined with DEFT-net, allows Adura to shift traditional mechanical and electronic complexity into software which increases efficiency and lowers overall systems costs.
