Part Number: DP83620

We are currently using this Ethernet device in our product. We need to know if this device has a Unique hard-coded MAC Address given by TI.

    Hello Saurav,

    Are you looking for the Organizationally Unique Identifier (OUI)? OUI is a part of MAC address but its not the whole MAC address. It is stored in 0x02 and 0x03 registers.

    Dear Aniruddha,

    Kindly confirm if the unique MAC address is hard coded in every chip, or should we assign a MAC address to our product in which we are using this chip.

    Thanks,
    Saurav

    Hello Saurav,

    MAC address is not hard coded in the device. The OUI is unique and it is hard coded in the device in register 0x2 and 0x3. You will have to assign MAC address on your product.

    Hi Aniruddha,

    If I am correct OUI will be same for all the Ethernet devices, but we need to assign MAC Address for the device which is being used in the product. How can we assign the Unique MAC Address to the all the Ethernet device being used in the product using this OUI ?

    Thanks,
    Saurav

    Hi Saurav,

    The MAC address is assigned to the MAC layer of the Ethernet stack. The MAC address is contained in whatever MAC that is controlling the DP83620. Typically the MAC is integrated into a microcontroller or microprocessor.

    The DP83620 is a physical layer device and does not have an assigned MAC address. OUI is a manufacturer number and is the same for all DP83620 devices, except possibly the revision number.

    Best Regards,
