Nuremberg, February 22nd 2005. Fujitsu Microelectronics Europe (FME) today announced the release of a FlexRay® Evaluation Kit. This FPGA-based development platform enables the design and verification of hardware and software applications before production silicon is available, enabling customers to get working FlexRay products to market in the fastest possible time.
This FlexRay Evaluation Kit is the first product in which Fujitsu will use the FlexRay controller IP that it recently licensed from Bosch. The Kit consists of an FPGA-board providing the FlexRay communication controller, the physical layer, and an MCU starter kit equipped with the MB91369, a 32-bit FR50 core. Along with the hardware comes a software package featuring a ready-to-use communication example. The software package includes a communication stack for the FlexRay controller IP that meets series production requirements for evaluation purposes or prototype development.
The modular design of the FPGA-board assures that any updates in the protocol or physical layer specifications can be implemented quickly without the need for a complete re-design. The board has pre-installed RS485 bus drivers. The board also provides sockets that allow third-party plug-in modules with FlexRay-compliant drivers to be added. The comprehensive package combined with the flexibility that FPGAs offer, will fulfil any requirements that designers need to develop FlexRay applications.
The MB91369 FR50 core has been chosen, as there are MCU starter kits already in use at many customers. The 32-bit RISC core has Harvard architecture, with a five-stage pipeline offering a single cycle instruction execution. This makes it powerful enough for the most demanding automotive applications. The 32-bit parallel bus interface of the FR50 core allows rapid access to the FlexRay controller.
Fujitsu will build on the FlexRay range by releasing a stand-alone ASSP during 2005, and in early 2006 the first embedded FlexRay 32-bit MCU will follow. Embedding FlexRay IP into a single-chip MCU will further advance the performance and range of automotive electronic control applications.
The FlexRay Evaluation kit is part of the exhibition at Embedded World 2005, Nuremberg, from February 22nd to 24th, where a demonstration will feature a working FlexRay-CAN gateway.
FlexRay is the newly established, time triggered protocol for networks with high requirements on safety aspects and a current bus speed of up to 10Mbit/s.
