ADAU1702 EEPROM Security

My Customer is ddevleoping a new Audio product and one question which has arisen is related the security of the EEPROM used to boot the ADAU1702, what provision exists to ensure the 'Sigma Studio design' is not available to copied from the serial bit stream between the ADAU and the EEPROM?

    Hi Joseph:

    Unfortunately there is no easy way to prevent clones for products within the 1701 / 1702. Customers have relied on some specifics of their products (difference in transducers, difference in user interfaces and other copyright features) to reduce this risk. Binaries cannot be reverse engineered and therefore the hackers could only clone their product blindly without understanding it's functionality. This makes it easy to identify in the market place. In SigmaStudio, you could use some DC cells as an identifier for you as a customer or a version number in your product. This would make it easy to police if clones appear in the market.

    There are complicated ways to have code protection but they all involve the need to have a microcontroller in the system and some handshaking mechanism that would prevent the code from executing correctly. If you would like to discuss your specific needs and would rather discuss this in a private thread, please let us know.
