... For a master application an external resistor in series with a diode should be connected between pin INH or pin V the data stream at the LIN bus input pin and transfers it via pin RXD to the microcontroller. In sleep mode the power consumption of the TJA1021 is very low. In failure modes the power consumption is reduced to a minimum. 2. Features 2 ...

... ElectroMagnetic Compatibility (EMC) performance due to wave shaping of the LIN output. The /20 version of the TJA1021 is optimized for the maximum specified LIN transmission speed of 20 kBd; the /10 version of the TJA1021 is optimized for the LIN transmission speed of 10.4 kBd as specified by the SAE J2602. 7.1 Operating modes The TJA1021 provides a mode of normal operation, an intermediate mode, a power-up mode and a very-low-power mode ...

... Sleep mode This mode is the most power-saving mode of the TJA1021. Despite its extreme low current consumption, the TJA1021 can still be woken up remotely via pin LIN, or woken up locally via pin WAKE_N, or activated directly via pin SLP_N. Filters at the inputs of the receiver (LIN), of pin WAKE_N and of pin SLP_N prevent unwanted wake-up events due to automotive transients or EMI ...

... NXP Semiconductors 7.4 Normal mode In normal mode the TJA1021 is able to transmit and receive data via the LIN bus line. The receiver detects the data stream at the LIN bus input pin and transfers it via pin RXD to the microcontroller (see the bus. The receiver has a supply-voltage related threshold with hysteresis and an integrated fi ...

... NXP Semiconductors 7.8 Wake-up source recognition The TJA1021 can distinguish between a local wake-up request on pin WAKE_N and a remote wake-up request via a dominant bus state. The wake-up source flag is set in case the wake-up request was a local one. The wake-up source can be read on pin TXD in the standby mode ...
