TJA1085 FlexRay active star coupler Rev. 1 — 23 October 2012 Product data sheet 1. General description The TJA1085 is a FlexRay active star coupler that can connect up to 4 branches of a FlexRay network. The TJA1085 is compliant with the FlexRay electrical physical layer specification V3.0.1 (see Ref. 1). Several TJA1085 devices can be connected via their TRXD0/1 interfaces to increase the number of branches in the network. A dedicated Communication Controller (CC) interface allows for integration into an ECU. The TJA1085 supports low-power management by offering bus wake-up capability along with battery supply and voltage regulator control.
