FlexRay™ - A key element in Fujitsu's automotive strategy

PDFFlex Cockpit Demo factsheet

MB88121: Fujitsu become the first to present Silicon for FlexRay™

The introduction of the new FlexRay communication protocol opens the door for future Automotive applications like X-by-wire, requiring enhanced safety features compared to today's automotive network systems. Fujitsu integrates FlexRay into its Automotive-proven 16-bit and 32-bit Microcontrollers and in doing so completes its product portfolio dedicated to the Automotive market.

The evolution of today's automobiles into highly integrated, safe, comfortable and reliable systems push the requirements for the automotive bus systems to the next level. The dramatic increase of multiple sensors, actuators and control systems require the combination of higher data rates, deterministic behaviour and fault tolerance making FlexRay the perfect backbone bus system. Flexibility in both bandwidth and system extension will also be key attributes as the need for increased functionality and on-board diagnostics also increases.

The first applications that will deploy FlexRay are chassis- and powertrain applications preparing the ground for the first x-by-wire applications which are estimated to become available around the end of this decade. As a member of the FlexRay consortium since 2002, Fujitsu is working to develop next-generation automotive by-wire applications.

With its wide range of products including CAN and LIN interface, Fujitsu's MCUs are the genuine solution for automotive applications such as body and comfort electronics, climate control, dashboards, infotainment & navigation, safety & sensor electronics, power-train control, chassis electronics and data backbone. The new FlexRay products will complete Fujitsu's offerings towards the automotive market.

Since September 2005 Fujitsu presented the first FlexRay communication controller to the market based on the ERAY protocol core by BOSCH. Meanwhile a second device MB88121A is available that supports the most recent protocol specification 2.1. It will be followed by MB88121B that will assure full compliance to the FlexRay protocol as it will be proven with respective test pattern currently under development at parities contracted by the FlexRay consortium.

The first MCUs with integrated FlexRay communication channels will be available in 2006. In order to empower customers to start their system development and design flow for FlexRay-based applications, Fujitsu has offered development tools like FPGA-based FlexRay-boards since 2005 and the new FlexRay starter kit available since December 2005 featuring the MB91F467D MCU and MB88121A.

FlexRay starter kit: SK-91F467-FLEXRAY

SK-91F467-FLEXRAY starter kit The SK-91F467-FLEXRAY is a multifunctional starter kit for the Fujitsu 32-bit Flash microcontroller MB91F467D series and Fujitsu FlexRay stand-alone communication controller MB88121. Together with the Softune Workbench Monitor debugger this single board is an autonomous platform for the development and testing of software. Alternatively, the starter kit provides a plug-in for an emulator for the MB91F460 family.

The starter kit is especially equipped for the analysis and use of the FlexRay bus system. The DECOMSYS::COMMSTACK driver library allows easy access to the FlexRay Communication Controller (MB88121). Pre-compiled examples free the user from own developments and demonstrate the capabilities of FlexRay. However with the configuration tool FlexConfig® the user can design his own communication matrix and generate the initialization code for the FlexRay Communication Controller (CHI files). The starter kit enables the designer to immediately start developing software for his application even before his own target system is available.

FlexRay evaluation board: SK-91465X-100PMC

SK-91465X-100PMC FlexRay evaluation board The SK-91465X-100PMC is a multifunctional evaluation board for the Fujitsu 32-bit Flash microcontroller series MB91460. It can be used stand-alone for software development and testing or as a simple target board to work with the emulator system. This board supports also FlexRay bus evaluation. By Hardware via the integrated FlexRay CC in MB91F465X series and the onboard FlexRay transceivers AS8221B Via the FlexRay drivers, Fujitsu FlexRay Driver or DECOMSYS::COMMSTACK library, an easy access the the FlexRay Communication Controller is possible. Pre-compiled examples frees the user form own developments and demonstrate the capabilities of FlexRay. However with the configuration tools FlexConfig® or DECOMSYS::DesignerPro (limited versions) the user can design its own communication matrix and generate the initialization code for the FlexRay Communication Controller.
