The TJA1081B is a FlexRay node transceiver that is fully compliant with the FlexRay
electrical physical layer specification V3.0.1. In order to meet the
JASPAR-specific requirements, it implements the ‘Bus driver increased voltage amplitude
transmitter’ functional class. It is primarily intended for communication systems from
2.5 Mbit/s to 10 Mbit/s and provides an advanced interface between the protocol
controller and the physical bus in a FlexRay network.
The TJA1081B features enhanced low-power modes, optimized for ECUs that are
permanently connected to the battery.
The TJA1081B provides differential transmit capability to the network and differential
receive capability to the FlexRay controller. It offers excellent EMC performance as well as
effective ESD protection.
The TJA1081B actively monitors system performance using dedicated error and status
information (that can be read by any microcontroller), along with internal voltage and
The TJA1081B supports mode control as used in the TJA1080A and is fully
function and footprint compatible with the TJA1081.
