FlexRay transceiver
Rev. 04 — 19 February 2009
Product data sheet
1. General description
The TJA1080ATS/2 is a FlexRay transceiver that is fully compliant with the FlexRay
electrical physical layer specification V2.1 Rev. A (see Ref. 1) and partly complies with
version V2.1 Rev. B. 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 TJA1080ATS/2 can be configured to be used as an active star transceiver or as a
node transceiver.
The TJA1080ATS/2 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 TJA1080ATS/2 actively monitors the system performance using dedicated error and
status information (readable by any microcontroller), as well as internal voltage and
temperature monitoring.
The TJA1080ATS/2 supports the mode control as used in NXP Semiconductors TJA1054
(see Ref. 2) and TJA1041 (see Ref. 3) CAN transceivers.
The TJA1080ATS/2 is the next step up from the TJA1080 FlexRay transceiver (Ref. 4).
Being fully pin compatible and offering the same excellent ESD protection, the
TJA1080ATS/2 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 TJA1080ATS/2 an excellent choice in any kind of FlexRay node.
See Section 14 for a detailed overview of differences between the TJA1080 and the
TJA1080ATS/2.
