TCAN1042-Q1: Interface with RM42x

Part Number: TCAN1042-Q1
Other Parts Discussed in Thread: HALCOGEN, TCAN4550-Q1

Hi,

We are designing a system using Hercules RM42x controller.

 I have configured CAN using Halcogen and available CAN examples in Halcogen.

Now we are trying to achieve more data rate upto 5Mbps using CAN FD.

With TI TCAN1042 is it possible to convert existing CAN Communication code to CAN FD?

Where can I find drivers and sample code for CAN FD?

Thanks

Regards,

Vishwas

    Hi Vishwas,

    TCAN1042 is a physical layer transceiver; it does not directly implement the CAN data protocol.  So, while the device is capable of supporting FD data rates (and meets the timing requirements for them defined in ISO 11898-2), an application would also need to use an FD-capable controller.  If your current solution (MCU, processor, etc.) is not capable of supporting CAN FD communication, then you might consider a device like TCAN4550-Q1.  It is a CAN controller capable of supporting FD and has an integrated CAN transceiver (similar to TCAN1042) and LDO.  This could be used with existing microcontrollers supporting classical CAN, since communication to the TCAN4550-Q1 chip is via SPI.

    Sample code for the TCAN4550-Q1 device is available via the product folder on ti.com:

    Please let me know if you have any questions.
