TM4C123GH6PM: Support for LIN

Part Number: TM4C123GH6PM

Does TM4C123GH6PMI have LIN support.

    I've just run a search across the full, "4C123 manual" (seeking LIN) - NO "Hits" resulted.

    As you likely know - LIN provides a lower cost & slower speed (primarily vehicular) communication implementation than the CAN Bus - was intended as an alternative (cost reducing) means to accommodate basic, non-critical vehicle functions.

    It (may) be possible to "massage" the 4C123 UART into (some) form of LIN capability - yet neither firm nor I have (yet) attempted.
    Note that MCUs from (others) do have proper LIN support - contact me via PM (here) if interested...

    The TM4C123GH6PM does not have all of the built in LIN support like the safety microcontroller RM41L232, or the rest of that family, but you can do LIN communication using the UART on the TM4C123GH6PM. The break generation and detection, as well as the 16 byte transmit and receive FIFO help support LIN communication. You will need to rely on the CPU to calculate and check checksums and identify slave ID's (if using as a LIN slave node).

    Sir,
    I need a controler with 2 CAN and LIN

    My Dad - and my "status (1LT) w/in the US Army" - earned such salutation.     Not so much, today.
    Such MCUs exist - you were advised to "contact via PM" through the forum. (you need to set this w/in your forum registration page)

    It is NOT good form to identify (others') devices from w/in this vendor's (public) forum... (PM method avoids such breach)

    The safety microcontroller I mentioned above,  RM41L232, has two CAN modules and a LIN module.

    Might it be noted that "LIN" is specifically aimed towards, "Non-Safety and/or Critical" Applications - while aiming for "Low Cost?"

    First post in response noted such...
