High-speed FlexRay transceivers from Infineon supports version 3.0.1

Infineon has launched new FlexRay transceivers ICs TLE 9221SX which are compliant with latest FlexRay Electrical physical layer specs version 3.0.1. These automotive specific ICs are suggested for use in designing control interface to suspension and chassis of cars and other such vehicles. These transceiver chips support data rates up to 10 Mb per second. They withstand high ESD of +/-10 KV.

In cars and other automotives, three interfaces are being extensively used . They are LIN, CAN and FlexRay. LIN is used up to the speeds of 20 Kb/second and CAN is used up to 1 Mb/second, whereas FlexRay can support 10 Mb/second.

“There is a noticeable trend towards extending the FlexRay bus from chassis control and body gateway applications to the powertrain domain, including engine and transmission control,” says Frank Schwertlein, Vice President and General Manager, Standard Power of the Automotive division at Infineon Technologies AG. “Infineon offers a fully certified FlexRay transceiver with extreme robustness and best-in-market ESD rating, capable of handling data rates of up to 10Mbit/s to support this market trend.”

Further points shared by Infineon includes:

Fully compliant to the most current FlexRay Electrical Physical Layer Specification version 3.0.1, the TLE9221SX is optimized for time-triggered networks with data transmission rates up to 10Mbit/s. It has very low electromagnetic emissions (EME) and therefore supports large networks and complex bus topologies. It is also optimized for high immunity against electromagnetic interferences (EMI) and as a result the device passed the electromagnetic compliance (EMC) tests at the Germany-based Ingenieurbüro für industrielle Elektrotechnik/Elektronik (IBEE), an internationally known independent test house for the automotive certification of transceiver products. Besides, the TLE9221SX features best-in-class ESD robustness of +/-10kV according to IEC61000-4-2 and HBM (human body model).

In addition, the TLE9221SX fulfills the latest revision of the German OEM Hardware Requirement Specification and is therefore pin-compatible and footprint-compatible to other FlexRay transceivers available in the market. The 16-pin TLE9221SX can easily be integrated into existing designs, because it can be placed on a 20-pin FlexRay transceiver footprint. Its bus pins are protected against short circuits to positive as well as negative battery voltage levels. Also, the device offers over-temperature protection including an integrated thermal shutdown.

RoHS compliant PG-SSOP-16 packaged TLE9221SX available immediately and the 14-pin PG-TSSOP version is planned for late 2014.
