IWR1642: Does IWR1642 IC and other mmwave IC have unique ID in IC??

Hi,

As title. if so. how to read that?

If mmWave IC didn't have unique ID after TI's production line

Is it possible to write unique ID to IC by register writing or something else??

Thanks.

Hello Austin,

The device has a unique Die ID which can read using the mmwavelink function rlGetRfDieId.

The mmw demo provides the "version" command which you can run on the CLI to get this information. To understand the implementation, please refer to the function CLI_MMWaveVersion() in C:\ti\mmwave_sdk_02_01_00_04\packages\ti\utils\cli\src\cli_mmwave.c. I have pasted the exact code snippet from this function below:

    /* Get the die ID: */
    retVal = rlGetRfDieId(RL_DEVICE_MAP_INTERNAL_BSS, &dieId);
    if (retVal < 0)
    {
        CLI_write ("Error: Unable to get the device die ID from mmWave link [Error %d]\n", retVal);
        return 0;
    }

    CLI_write ("Lot number              : %d\n", dieId.lotNo);
    CLI_write ("Wafer number            : %d\n", dieId.waferNo);
    CLI_write ("Die coordinates in wafer: X = %d, Y = %d\n",
               dieId.devX, dieId.devY);
