NXP TJA1080A Transceiver Passes FlexRay Physical Layer Conformance Test

NXP, the independent semiconductor company founded by Philips, announced that the TJA1080A has passed the FlexRay Physical Layer Conformance Test, the industry standard for FlexRay products, making it the first transceiver to comply with this test. TJA1080A will be commercially available in the second quarter in 2008.

“The TJA1080A transceiver addresses car manufacturers’ need for faster, fault-tolerant communication systems which are flexible and scalable. Compliance to the FlexRay Physical Conformance Test is an important step in the proliferation of the FlexRay standard in the automotive industry,” said Rob Hoeben, FlexRay marketing manager, NXP. “For our customers, this step means faster development times and fewer issues in production later. NXP is currently the only semiconductor supplier that can provide full compliance in a FlexRay solution that meets the industry standard.”

With the high-speed FlexRay network communications system, carmakers can introduce advanced features that are transforming safety and comfort in the car. Aimed primarily at communication systems from 1Mbit/s to 10Mbit/s, the TJA1080A provides an advanced interface between the protocol controller and the physical bus in a FlexRay network. FlexRay is the first networking standard to enable these features, compared to existing networking standards such as CAN and LIN. It can be configured as an active star or node transceiver. Moreover, the TJA1080A is fully TJA1080-compatible and there are no software adaptations necessary when switching from the TJA1080 to TJA1080A.

Secure communications on the FlexRay network system are assured through active monitoring of system performance using dedicated error and status information, readable by any microcontroller. The device also monitors internal voltage and temperature and supports the mode control used in NXP’s TJA1055 and TJA1041 CAN transceivers. A Bus Guardian interface enables the TJA1080A to be used in systems that require additional supervisions. The transceiver’s excellent EMC performance is complemented by high ESD protection. While in active star and node configurations, features such as sleep and standby power modes improve automotive power management.

The TJA1080A transceiver delivers a number of significant enhancements over TJA1080, its predecessor:

  • Improved power-on reset behavior
  • Fully conforms to Electrical-Physical Layer V2.1
  • Upgraded transmitter circuit to reduce emission on bus lines
  • Enhanced receiver circuit – higher RF immunity, up to 70 ns minimum bit time

About FlexRay and the FlexRay Consortium
FlexRay is the automotive standard for deterministic, fault-tolerant, high-speed data communication and it clearly delivers the networking performance demanded by new enhanced automotive applications such as brake-by-wire and steer-by-wire. The FlexRay Consortium is an organization formed to drive the adoption of an open standard for high-speed bus systems for distributed control applications in automobiles. Since forming in September 2000, the Consortium has grown to include the automotive industry’s largest and most influential players. FlexRay development is being driven by the Core Partner companies, BMW, DaimlerChrysler, Freescale Semiconductor, GM, NXP Semiconductors, Robert Bosch and Volkswagen. Various membership levels provide the ability to interact with the FlexRay Consortium working groups, propose ideas, participate in review meetings, and have early access to the specifications, as well as the opportunity to actively participate in the adoption of this global standard. A complete list of member companies, directions on how to apply for membership and other information is available at the Consortium website.
