1. General description
The TJA1080A is a FlexRay transceiver, which is in line with the FlexRay electrical
physical layer specification V2.1 Rev. A (see Ref. 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
(see Ref. 2) and TJA1041 (see Ref. 3) CAN transceivers.
The TJA1080A is the next step up from the TJA1080 FlexRay transceiver (Ref. 4). 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 70 ns minimum bit time
Improved bus error detection functionality
This makes the TJA1080A an excellent choice in any kind of FlexRay nodes.
See Section 14 for a detailed overview of differences between the TJA1080 and the
TJA1080A.
2. Features

I Compliant with FlexRay electrical physical layer specification V2.1 Rev. A (see Ref. 1)
I Automotive product qualification in accordance with AEC-Q100
I Data transfer up to 10 Mbit/s
I Support of 70 ns minimum bit time
