.. TJA1082 FlexRay node transceiver Rev. 01 - 1 July 2009 Preliminary data sheet 1. General description The TJA1082 FlexRay node transceiver is patible with the FlexRay electrical physical layer specification V2.1 Rev. B (see Ref. 1). It also incorporates Features and parameters anticipated to be included in V3.0, currently being finalized. It is primarily intended for munication systems operating at between 2.5 Mbit/s and 10 Mbit/s, and provides an advanced interface between the protocol controller and the physical bus in a FlexRay network. The TJA1082 offers an optimized solution for Electronic Control Unit (ECU) applications that do not need enhanced power management and are typically switched by ignition or activated by a dedicated wake-up line. The TJA1082 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 TJA1082 actively monitors system performance using dedicated error and status information (readable by any microcontroller), as well as internal voltage and temperature monitoring. 2.
