    Silicon generated serial number

    douglas.mcclean

      Reading the data sheet for the USBFS component suggests that the PSoC Creator will eventually have a feature for supplying the USB device serial number with a "Silicon Generated Serial Number." I understand from the PSoC Creator errata that this feature is not yet implemented.

         

      Does that mean that the PSoC hardware includes some sort of read-only unique-per-chip serial number? If so, could you briefly describe how to access it? I have need of such a serial number and was considering adding another chip to my design which functions as a silicon serial number (a DS2401), but obviously I would prefer not to do that if there is already such a number available somewhere.

         

      A quick search of the PSoC 3/5 Registers TRM (for the word "serial") didn't turn up anything, but it's an 1800 page document.
