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.
Features and benefits
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
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 VIO, VCC, VBUF and VBAT
? Auto I/O level adaptation to host controller supply voltage VIO
? Can be used in 14 V, 24 V and 48 V powered systems
? Enhanced bus error detection - detects short-circuit conditions on the bus
? Instant transmitter shut-down interface (BGE pin)
? Selective branch shut-down (partial networking)
Robustness
? Bus pins protected against ?8 kV ESD pulses according to HBM and ?6 kV ESD
pulses according to IEC61000-4-2
? All pins protected against ?1000 V ESD according to CDM
? All pins protected against ?200 V ESD according to MM
? No reverse currents from the digital input pins to VIO or VCC when the TJA1085G is not powered up
? Bus pins short-circuit proof to battery voltage (14 V, 24 V or 48 V) and ground
? Overtemperature detection and protection
? Bus pins protected against transients in automotive environment (according to ISO
7637 class C)
Active star functional classes
? Active star - communication controller interface
? Active star - bus guardian interface
? Active star - voltage regulator control
? Active star - logic level adaptation
? Active star - host interface
? Active star - increased voltage amplitude transmitter
