austriamicrosystems presents the worldwide first FlexRay transceiver produced in series, certified to the FlexRay specification V2.1 Rev B

FlexRay is capable of transmission rates of up to 10 Mbit/s, 20 times the speed of unshielded twisted copper cables used in cars today. The FlexRay standard, therefore, demands that each transceiver device fulfills particular requirements, as communication on the combined network must not only be fast, but also extremely reliable. The AS8221 Standard Transceiver is the undisputed champion in terms of system stability, which is a key prerequisite to network structure. Its exceptionally short asymmetric delay is another advantage when planning the network structure.

austriamicrosystems’ AS8221 FlexRay Standard Transceiver provides all of the functions to enable its integration in Electronic Control Units powered with permanent battery voltage. While the microchip is only fed by the car battery, it provides wake-up functionality via the network and is therefore responsible for controlling the local voltage supply. Another safety feature of the AS8221 is its interface to optionally monitor circuits (e.g. bus guardian), which can, in safety-critical applications, uncouple the control unit from the communication network in case of a fault, thus ensuring communication across the remaining network.

“The AS8221 FlexRay Standard Transceiver is the first IC in austriamicrosystems’ FlexRay transceiver family, manufactured in serial production, that helps increase the stability and interoperability of FlexRay network communication“, says Bernhard Czar, Marketing Director Automotive at austriamicrosystems. “We design and develop our devices not only to meet the FlexRay standard, but to focus specifically on the implementation of innovations that exceed the standard.”
