austriamicrosystems presents its FlexRay Transceiver product family at the FlexRay Product Day

austriamicrosystems presents the AS8220 FlexRay Basis Transceiver, the AS8221 FlexRay Standard Transceiver and the AS8224 FlexRay Active Star Device.

FlexRay Transceiver family including the new AS8224 Active Star Device is designed according to the newest FlexRay standard release

The transceiver products are designed according to the FlexRay Electrical Physical Layer Specification V2.1 Rev B with enhanced performance. The AS8221 is designed for ECUs connected to permanent battery supply (clamp 30) where the transceiver manages the ECU power-up via its inhibit output pins. The AS8220 is a sister device addressing ECUs supplied with switched battery voltage where no FlexRay bus wake-up functionality is needed.

The AS8224 is a brand new FlexRay Active Star Device offering 4 FlexRay branches where each branch can be individually controlled and performs a failure detection procedure. The newly introduced device manages message forwarding on 6 communication paths, the communication controller interface, the 4 FlexRay branches and the Interstar interface to enhance FlexRay Active Stars for higher branch count. The AS8224 supports host controlled as well autonomous mode handling allowing the FlexRay Active Star to fully act as a FlexRay gateway when no microcontroller is connected, without interaction from external logic devices.
