TJA1080TS

General description

The TJA1080 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 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 NXP Semiconductors TJA1054 (see Ref. 2) and TJA1041 (see Ref. 3) CAN transceivers.

Features

Optimized for time triggered communication systems

• Data transfer up to 10 Mbit/s
• Usable for 14 V and 42 V powered systems
• Very low ElectroMagnetic Emission (EME) to support unshielded cable
• Differential receiver with high common-mode range for ElectroMagnetic Immunity (EMI)
• Transceiver can be used for linear passive bus topologies as well as active star topologies
• Auto I/O level adaptation to host controller supply voltage V_IO
• Bus guardian interface included
• Automotive product qualification in accordance with AEC-Q100

Low power management

• Low power management including two inhibit switches
• Very low current in Sleep and Standby mode
• Wake-up via wake-up symbol on the bus lines (remote), negative edge on pin WAKE (local), and a positive edge on pin STBN if V_IO is present
• Wake-up source recognition
• Automatic power-down (in Star-sleep mode) in star configuration

Diagnosis (detection and signalling)

• Overtemperature detection
• Short-circuit on bus lines
• V_BAT power-on flag (first battery connection and cold start)
• Pin TXEN and pin BGE clamping
• Undervoltage detection on pins V_BAT, V_CC and V_IO
• Wake source indication

Protections

• Bus pins protected against 8 kV HBM ESD pulses
• Bus pins protected against transients in automotive environment (ISO 7637 class C compliant)
• Bus pins short-circuit proof to battery voltage (14 V and 42 V) and ground
• Fail-safe mode in case of an undervoltage on pins V_BAT, V_CC or V_IO
• Passive behavior of bus lines in the event that transceiver is not powered
