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.
