TJA1081TS - Brand New NXP Semiconductors Interface - Specialized
-
General description
The TJA1081 is a FlexRay node transceiver that is fully compliant with the FlexRay electrical physical layer specification V2.1 Rev. A (see Ref. 1) and partly complies with versions V2.1 Rev. B. In addition, the TJA1081 already incorporates features and parameters anticipated to be included in V3.0, currently being finalized. It is primarily intended for communication systems from 1 Mbit/s to 10 Mbit/s, and provides an advanced interface between the protocol controller and the physical bus in a FlexRay network.
The TJA1081 features enhanced low-power modes, optimized for ECUs that are permanently connected to the battery.Features
