Description
- 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.
- Features
- 2.1 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 VIO
- ■ Bus guardian interface included
- ■ Automotive product qualification in accordance with AEC-Q100
- 2.2 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 VIO is present
- ■ Wake-up source recognition
- ■ Automatic power-down (in Star-sleep mode) in star configuration
- 2.3 Diagnosis (detection and signalling)
- ■ Overtemperature detection
- ■ Short-circuit on bus lines
- ■ VBAT power-on flag (first battery connection and cold start)
- ■ Pin TXEN and pin BGE clamping
- ■ Undervoltage detection on pins VBAT, VCC and VIO
- ■ Wake source indication
- 2.4 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 VBAT, VCC or VIO
- ■ Passive behavior of bus lines in the event that transceiver is not powered
