General description

The TJA1080ATS/2 is a FlexRay transceiver that is fully compliant with the FlexRay electrical physical layer specification V2.1 Rev. A (see Ref. 1) and partly complies with version V2.1 Rev. B. It is primarily intended for communication systems from 1 Mbit/s to 10 Mbit/s, and provides an advanced interface between the protocol controller and the physical bus in a FlexRay network.

The TJA1080ATS/2 can be configured to be used as an active star transceiver or as a node transceiver.

The TJA1080ATS/2 provides differential transmit capability to the network and differential receive capability to the FlexRay controller. It offers excellent EMC performance as well as high ESD protection.

The TJA1080ATS/2 actively monitors the system performance using dedicated error and status information (readable by any microcontroller), as well as internal voltage and temperature monitoring.

The TJA1080ATS/2 supports the mode control as used in NXP Semiconductors TJA1054 (see Ref. 2) and TJA1041 (see Ref. 3) CAN transceivers.

The TJA1080ATS/2 is the next step up from the TJA1080 FlexRay transceiver (Ref. 4). Being fully pin compatible and offering the same excellent ESD protection, the TJA1080ATS/2 also features:

  • Improved power-on reset concept
  • Improved ElectroMagnetic Emission (EME)
  • Support of 60 ns minimum bit time
  • Improved bus error detection functionality

This makes the TJA1080ATS/2 an excellent choice in any kind of FlexRay node.

See Section 14 for a detailed overview of differences between the TJA1080 and the TJA1080ATS/2.
