The TJA1027 is the interface between the Local Interconnect Network (LIN) master/slaveprotocol controller and the physical bus in a LIN network. It is primarily intended forin-vehicle sub-networks using baud rates up to 20?kBd and is compliant with LIN?2.0,LIN?2.1, LIN?2.2, LIN?2.2A and SAE?J2602. The TJA1027 is pin-compatible with theTJA1020 and the TJA1021.\nThe transmit data stream generated by the protocol controller is converted by theTJA1027 into an optimized bus signal shaped to minimize ElectroMagnetic Emissions(EME). The LIN bus output pin is pulled HIGH via an internal termination resistor. For amaster application, an external resistor in series with a diode should be connectedbetween pin VBAT and pin LIN. The receiver detects a receive data stream on the LIN businput pin and transfers it via pin RXD to the microcontroller.\nPower consumption is very low in Sleep mode. However, the TJA1027 can still be wokenup via pins LIN and SLP_N.\n
