Do I need to obtain OUI from IEEE if I use AT24MAC602 chip for ZigBee MAC?

I'm preparing the manufacturing of some ZigBee devices with Atmega256RFR2. There are AT24MAC602 chips on PCBs for obtaining of unique 64-bit MAC address. This MAC consists of 24-bit Atmel's OUI (organization code) and other bits. Can I legally use Atmel's OUI in devices manufactured by another vendor? I looked up some discussions about it. E. g. https://www.avrfreaks.net/forum/w... . The con- is that ZigBee alliance said that yes - ZigBee MAC has to contain unique organization code OUI. The pro- is that, e. g. notebook manufacturers do not replace OUI of Ethernet or WiFi modules. If I can't use Atmel OUI then what the metter to buy AT24MAC602 at all?

I'd ask official support, since this is more of a policy question, rather than technical question. I personally would assume that there is no problem and you can use the ID as is.

 

AT24MAC602 contains unique ID, which you can use in connection with your own OUI, so it is still useful.

Thank you for your reply, Alexru. I will ask Atmel.

Atmel's support reported that using AT24MAC602 I may relax about obtaining MAC and OUI. I can just use Atmel's MAC in end device. Disadvantage is that advanced user will see Atmel name in MAC but not your company name. It is just blank problem for us now. I think that ZigBee alliance may have another point of view. E.g. I know, that there is no special requirements about BT Smart MAC. But ZigBee alliance policy is more strict. I'll try to ask em, because we are interested in further legal compatibility with other ZigBee devices and standard ZigBee profiles.

ZigBee Alliance will not care. I've seen many products using chip vendor's OUI.
