austriamicrosystems introduced its FlexRay transceiver AS8221 during this week's Embedded World 2005 in Nuremberg. During the fair, the AS8221 was on display as part of a fujitsu FlexRay cluster and diagnosis system with a maximum speed of 10Mbps at the Fujitsu Microelectronics booth.

The AS8221 supports cost-optimized high-speed, fault-tolerance time-triggered applications operating as an interface between a FlexRay communication controller and the copper wire physical bus. The new device provides various bus and failure diagnostics, making it suitable for high-speed automotive bus systems, safety-critical applications, X-by-wire systems and time-triggered bus systems. Both the high-side driver and the low-side driver are included, resulting in an absolutely symmetric signal with significant driver capabilities.

"The AS8221 FlexRay transceiver will be the first transceiver available on the market in volume for bandwidths up to 10Mbps in automotive applications," commented Bernd Gessner, GM of austriamicro's Automotive business unit. "This new product clearly demonstrates the advantages of our 0.35?m high voltage process, and the extensive know-how and experience of our design engineers for high voltage applications," Gessner added.

FlexRay system

FlexRay is a new network communication system targeted specifically at the next generation of high bandwidth automotive applications like "by-wire" applications. These applications demand high-speed bus systems that are deterministic, fault-tolerant and capable of supporting distributed control systems, the company explained.
