TJA1080ATS/2/T,118 - NXP Function Overview

Overview
The TJA1080A is a FlexRay transceiver that is fully compliant with the FlexRay electrical physical layer specification V2.1 Rev. A. In addition, it incorporates features and parameters included in V3.0.1. 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 TJA1080A can be configured to be used as an active star transceiver or as a node transceiver.
The TJA1080A provides differential transmit capability to the network and differential receive capability to the FlexRay controller. It offers excellent EMC performance as well as high ESD protection.
The TJA1080A actively monitors the system performance using dedicated error and status information (readable by any microcontroller), as well as internal voltage and temperature monitoring.
The TJA1080A supports the mode control as used in NXP Semiconductors TJA1054 and TJA1041 CAN transceivers.
The TJA1080A is the next step up from the TJA1080 FlexRay transceiver. Being fully pin compatible and offering the same excellent ESD protection, the TJA1080A also features:
Improved power-on reset concept
Improved ElectroMagnetic Emission (EME)
Support of 60 ns minimum bit time
Improved bus error detection functionality
This makes the TJA1080A an excellent choice in any kind of FlexRay node.
