AS8223-AMFM

Specialized Overview

The AS8223 is a monolithic FlexRay compliant Active Star Device that manages communication traffic among four FlexRay branches of the network, expandable to more branches through an Interstar interface. The four branches operate as FlexRay receivers and transmitters, with one path acting as a receiver while others transmit. It features a Host Controller Interface for active control of power modes and error diagnosis, and enters autonomous mode without host controller intervention. A Communication Controller interface provides standard transceiver functionality on the ECU. The product is available in a 44-pin MLF (9x9) package.
