TJA1080
FlexRay transceiver
Rev. 01 — 20 July 2006
Preliminary data sheet
1. General description
The TJA1080 is a FlexRay transceiver, which is compatible 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 TJA1080 can be configured to be used as an active star transceiver or as a node
transceiver.
The TJA1080 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 TJA1080 actively monitors the system performance using dedicated error and status
information (readable by any microcontroller), as well as internal voltage and temperature
monitoring.
The TJA1080 supports the mode control as used in Philips TJA1054 (see Ref. 2) and
TJA1041 (see Ref. 3) CAN transceivers.
