IWR6843: IWR6843， Is there a serial ID can be used to identify a unique chip?

Hi

In iwr6843, is there a fixed unique ID (or some registers) can be read by software to identifiy each different chip? I want to achieve a feature which is similar to SN(serial number) in my mass production devices, inorder to reduce BOM cost, I don't like to add an EEPROM in this design. If there is a unique ID in iwr6843, I think it can be used. 

Regards
