SN65HVD231: spec

Part Number: SN65HVD231

Dear team

There is currently a project that uses TI CAN transceiver SN65HVD231, but the customer requires it to support CAN 2.0B 29bit. I confirm that the MCU currently used supports it, but is it also possible to support CAN transceivers? This part is not very clear, and the SN65HVD231 spec did not check it. Arrived, so could you help to confirm it,

thank you.

    Hi Denny,

    CAN 2.0B defines the data layer of the CAN interface. This revision added support for extended 29-bit identifiers in the CAN frame. Because SN65HVD231 is only a CAN transceiver, it does not care about the data-layer used with it. It is only concerned with the physical layer requirements of the CAN standard. 

    As long as the data rate of the system is supported by the transceiver and the CAN controller (MCU) supports the CAN 2.0B protocol requirements, this setup will not have an issue meeting CAN 2.0B functionality. 

    Let me know if you have any more questions.

    Regards,
    Eric Schott
