Part Number: TCAN4550

Tool/software:

Hi team,

Could you show us how we can test TCA4550 to meet CAN BUS 5M bps?

Thanks,

Leo

    Hi Leo,

    Please refer to the TCAN45xx Software User's Guide (Link) for instructions on how to configure the TCAN4550 and how to send and receive CAN messages.

    Additional information about the CAN FD Controller (MCAN) features and configuration can be found in the M_CAN User's Manual (Link).

    Regards,

    Jonathan

    Hi Jonathan,

    Consider the CAN BUS interface behavior, Do you think CAN BUS (TCAN4550) can perform the Tx/Rx  auto for SI measurement ?

    For Test mode, Does it support loop back mode and silent mode?

    Thanks,

    Leo

    I don't know what you are referring to.  The TCAN4550 doesn't "perform" any measurements.  It sends and receives messages on a CAN bus.

    Yes.  Please review the datasheet and M_CAN User's manual for details.

    Hi Jonathan,

    After customer follow the Software user guide for instruction to configure the TCAN4550 to send and receiver CAN message.

    How to Test CAN FD meet customer requirement with Data Speed > 5Mbps?

    Thanks,

    Hi Leo,

    The bit rate is adjusted by changing the number of time quanta (tq) allocated for the DTSEG1 and DTSEG2 fields in the Data Bit Timing and Prescaler (DBTP) register (0x100C).

    With a 40MHz clock frequency, there are 8 tq per bit which is the total number allocated for DTSEG1 and DTSEG2 fields.  Therefore to increase the bit rate, the total number of tq needs to be reduced.

    Regards,
