AS8223 FlexRay Active Star Device

AS8223 FlexRay Active Star Device

The AS8223 is a monolithic FlexRay compliant Active Star device which manages communication traffic between the communication controller interfacen and four FlexRay branches. It's also expandable to more branches through an Interstar interface. One of the communication paths is operating as receiver while the others operate as transmitters. The four branches of the AS8223 consist of a FlexRay receiver and transmitters which support the bus wake-up function. Additionally, the AS8223 comes with a Host Controller Interface to achieve active control of the power modes and error diagnosis. An autonomous mode is entered automatically, in which the device operates without the need for a host controller. The built in communication controller interface provides the standard transceiver functionality on the ECU using the AS8223. The FlexRay Active Star Device is available in MLF 9x9 44 pin package.
