CC2652R7: CAN Controller Functionality

Ryan T
Expert 3161 points

Part Number: CC2652R7

Hi Team,

Customer is asking about support for CAN controller functionality to meet ISO11898 standard in the CC2652R7--are we able to support drivers on this device? Are there any memory limitations for running this?

Best regards,

-RT

    Hi RT,

    There should not be any limitations concerning memory, but SimpleLink wireless MCUs do not have integrated CAN hardware.  An external CAN controller with an integrated CAN FD transceiver, TCAN4550-Q1 or TCAN4551-Q1, should be utilized to support data rates up to 5 Mbps. I've asked the Automotive Team to give additional information.

    Regards,
    Ryan

    Hi RT,

    We do not provide an official driver to enable CAN in our SDK but do have a plan to provide a CAN driver in the SDK later this year. We have some reference design examples where we have demonstrated the HW setup for such an interface. You can reference for example this TI Design. https://www.ti.com/tool/TIDA-020032

    We also provided some example code (not fully productized or tested) here which can be used to enable a proof of concept: https://github.com/TexasInstruments/CC26XX-TCAN4550-EXAMPLES

    Please keep in mind that while we are providing a driver, we are not providing a full CAN stack. We recommend customers seek to contact a third party for further CAN development if they do not have a CAN stack of their own.
