CC1310: MAC addresses

Marcin Bylica

Part Number: CC1310

Hi,
I have a question about the MAC addresses on CC1310 and CC1312.
I noticed that in our samples the oldest 4 Bytes of this address are always 0x00124B00.
Can we expect that this will continue to be the case in microcontrollers from other production series?
Can it be expected that processors bought on one spool will have a unique end of the last two Bytes of this address?

Thank you and regards,

Marcin.

    1. I suppose ,prefix 0x00124B00 of TI 15.4 wireless chip would keep for a long while so you can expect it will continue to be the case.

    2. Couldn't understand what you mean on "Can it be expected that processors bought on one spool will have a unique end of the last two Bytes of this address?"

    I struggle a bit with finding a good overview of how the MAC address is built up. 

    As I have understood it every vendor gets a range of addresses to use and the vendor ID is part of the address. But it could be that a vendor has more than one ID if they have used all addresses provided with the original ID. 

    Meaning that the probability is high that part of the MAC address will remain constant but you will not be guarantied that it will be the same for a given number of chips.
