TJA1085HN: FlexRay active star coupler
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/ISO17458-4
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.
The TJA1085 meets industry standards for EMC/ESD performance and provides
enhanced bus error detection, low current consumption and unmatched asymmetric delay
performance.
The TJA1085 also fulfills the JASPAR requirements as defined by the Japanese car
industry.
