Is there a unique ID field anywhere in the MSP430 (F5529) that is available to the user? It would be very useful for unique product identification and security.

    Yes, MSP430x5xx and MSP430x6xx have unique LotWafer / DieX / DieY combination inside TLV structrure (DIE record). There is device descriptors (TLV) table inside each device datasheet.
