World's first star coupler certified according to the FlexRay(TM) Electrical Physical Layer (EPL) Specification V3.0

For efficiently connecting up to four branches of a FlexRay(TM) Network

Stutensee, (PresseBox) - Gleichmann Electronics now offers the new E981.56 FlexRay(TM) star coupler from ELMOS Semiconductor. The E981.56 is especially designed for efficient implementation of gateways and domain controllers placed in the center of a star-shaped FlexRay(TM) network. It is the first star coupler worldwide that has been awarded certification according to the current FlexRay(TM) Electrical Physical Layer (EPL) Specification V3.0.

The E981.56 is fully downward compatible with the preceding 1st generation E981.56 device and comes in a 44-pin QFN (Quad Flat No-leads) package with 9 mm edge length and is qualified according to AEC-Q100. It is designed for a temperature range of -40°C to +125°C and a wide supply voltage range of 5.5 V to 18 V. Furthermore, the E981.56 fulfills the requirements of vehicle manufacturers with respect to electromagnetic compatibility (EMC) and electrostatic discharge (ESD).

Thanks to the four independent physical bus drivers for transmitting and receiving FlexRay(TM) messages, up to four branches of a FlexRay(TM) network can be connected with each other with a star coupler. The number of the network's supported branches can be increased according to a modular principle by connecting several star couplers with each other via the integrated intra-star interface.

Configuration by means of a microcontroller and the exchange of diagnosis data are executed via the SPI compatible host-controller interface. Optionally, an integrated interface to a communication controller enables use of the E981.56 as a standard transceiver or as autonomous repeater entirely without an additional controller.

Detailed information about the E981.56 is available and can be requested by sending an Email to Samples and evaluation boards are available upon request.

MSC Technologies GmbH

Founded in 1979, Gleichmann & Co. Electronics GmbH, in the same company group with MSC Vertriebs GmbH, has established itself as one of the leading pan-European distributors of electronic assemblies and components. One of the reasons for the high acceptance by customers and suppliers is the company's early focus on comparatively few, highly sophisticated products such as microcontrollers, programmable logic devices, displays and customer specific power supplies. From this, the resulting in-depth technical know-how of our sales engineers and field application engineers today enables us, if required by the customer, even implementation of complete new designs right up to the finished product. With two of its own ASIC design centers, the Gleichmann Electronics Research laboratory and one of the largest and most modern programming centers in Europe, Gleichmann & Co Electronics takes a leading role in terms of service and customer support.
