IC conforms to FlexRay Standard 2.1 Rev B

Offered as the first monolithic FlexRay Standard v2.1 Rev B-compliant Active Star Device, the AS8223 manages communication traffic among four FlexRay branches of the network, expandable to more branches through an Interstar interface. The four branches of the part operate as a FlexRay receiver and transmitter whereby one of the communication paths is operating as receiver while the others operate as transmitter. It also is claimed to offer best-in-class EMC immunity performance.

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 built into the AS8223 to provide standard transceiver functionality on the ECU using the AS8223. Other features include a very low asymmetric delay contribution, data transfer up to 10 Mbits/s, enhanced bus error detection with current sensing on FlexRay branches up to 8 m from connector pins, and very low contribution to the FlexRay network asymmetric delay. Housed in 44-pin MLF packages, the part operates over a temperature range of –40° to 125°C with a wide power supply range of 5.5 to 40 V. ($8 ea/1,000 — available now.)
