Chip First To Meet FlexRay 2.1 Rev B

Touting best-in-class EMC immunity performance, the AS8223 claims position as the industry’s first monolithic FlexRay Standard V2.1 Rev B compliant Active Star Device. The chip manages communication traffic among four FlexRay branches of the network, expandable to more branches through an Interstar interface. Four branches of the AS8223 operate as a FlexRay receiver and transmitter whereby one of the communication paths is operating as receiver while the others operate as transmitter.  Additionally, the device comes with a host controller interface to achieve active control of the power modes and error diagnosis. A communication controller interface is also on board to provide standard transceiver functionality on the ECU. In a 9 mm x 9 mm, 44-pin MLF package, price for the AS8223 is $8 each/1,000.
