TCAN1043A-Q1: Do we have products for CAN<->CANFD converters?

Other Parts Discussed in Thread: TCAN1043,

Hi Team

We had DIN TCAN1043 !

Currently would like to searching products for CAN<->CANFD converters!

Because the Test object uses TCAN1043 (CAN FD), and the other side is vehicle spy (which is traditional CAN), and the message displayed on the vehicle spy side is no response now! THX

    Kygo,

    We don't have any products that do this, and would likely have to be the work of a digital or controller device. The CAN FD frame not only has a larger data payload, but a different bit pattern at the beginning of the frame that indicates it's a CAN FD frame (dominant bit where in a classic CAN frame would be a recessive bit). 

    All that being said, the transceiver should have no effect on this, it's all on the controller side. So are both controllers communicating with CAN FD, but when the TCAN1043A-Q1 was placed in the design the messages are no longer being displayed correctly? If so, can we get waveform images of RXD, CANH, and CANL and a schematic?

    Also, this DIN is for which customer?

    Regards,
