Transceiver ISO 9141

Other Parts Discussed in Thread: TLIN1027-Q1

Hello, my name is Aaron, engineer of the R+D+i Department of the Rother Industries & Technology company.

I would like know if existing any transceiver that meets with standar ISO 9141 compatible interface functions, because I need a transceiver that has K-line and L-line.

Thanks & regards,
Aaron.

    Aaron,

    Thanks for bringing this to E2E. Texas Instruments doesn't have any transceivers that are compliant with ISO 9141, but the TLIN1027-Q1 is compatible with K-Line and L-Line applications due to its ability to communicate at low data rates. There are also no plans to create ISO 9141 compliant drivers.

    Hello Eric, 

    I have a questions about the compatibility of TLIN1027-Q1 with ISO 9141. In datasheet of TLIN1027-Q1 I can see only one LIN line.

    If I connect an Electronic Control Unit (ECU) that has K-line and L-line,  both lines, or just the K-line, can be used in communication.

    How can I know if the line is K-line or L-line to transmit/receive data if the line is LIN?

    Regards,

    Aaron

    Aaron,

    My expertise is not in K-Line or L-Line. That compatibility for the TLIN1027-Q1 to work with K-Line is merely because the data rate can be very low because dominant timeout is removed, and the signaling scheme is similar. Can you elaborate a little more on your issue? 

    Regards,

    I would like to know if in the case of the communication with one or more Electronic Control Unit (ECU) it is possible to know which line has been used to transmit the data (if is K-line or L-line).

    The TLIN1027-Q1 transceiver only has one LIN line, how do I know which line the data comes from?

    Regards,

    Aaron

    Aaron,

    The TLIN1027-Q1 is just going to translate the signal, so there's no intelligence to know if it came from K-Line or L-Line. This device is a LIN transceiver, and LIN only has one communication line. It was not developed for applications where both K-Line and L-Line will be used, so determining which communication line transmitted the data can't be done.

    If you can share some kind of block diagram of what you expect, we may be able to assist you further.
