TJA1085G

FlexRay active star coupler

Rev. 1 — 28 February 2017

Product data sheet

1. General description

The TJA1085G is a FlexRay active star coupler that can connect up to 4 branches of a

FlexRay network. The TJA1085G is compliant with the FlexRay electrical physical layer

specification V3.0.1/ISO17458-4 (see Ref. 1 and Ref. 2).

Several TJA1085G 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 TJA1085G supports low-power

management by offering bus wake-up capability along with battery supply and voltage

regulator control. The TJA1085G meets industry standards for EMC/ESD performance

and provides enhanced bus error detection, low current consumption and unmatched

asymmetric delay performance.

2. Features and benefits

2.1 General

 Compliant with FlexRay Electrical Physical Layer specification V3.0.1/ISO17458-4

 Automotive product qualification in accordance with AEC-Q100

 Data transfer rates from 2.5 Mbit/s to 10 Mbit/s

 Supports 60 ns minimum bit time at 400 mV differential voltage

 Low-power management for battery-supplied ECUs

 Very low current consumption in AS_Sleep mode

 Leadless HVQFN44 package with improved Automated Optical Inspection (AOI)

capability

2.2 Functional

 Supports autonomous active star operation independent of the host ensuring the

TJA1085G remains active even if the host fails or is switched off

 Branches can be independently configured

 Branch extension via TRXD0/1 inner star interface

 16-bit bidirectional SPI interface up to 2 Mbit/s for host communication

 Full host control over branch status

 Enhanced wake-up capability:

 Remote wake-up via wake-up pattern and dedicated FlexRay data frames

 Local wake-up via pin LWU

 Wake-up source recognition

 configurable per branch

 Enhanced supply voltage monitoring on V_IO, V_CC, V_BUFand V_BAT
