    20704 a1/a2 revisions and USB wake modes

    GrahamS_21

      I am supporting a customer using the CYW20704 and need some help answering some questions.

       

      1. What is the difference between the A1 and A2 revisions of the silicon. Customer has both and would like to know what the errata on the A1 was that was fixed on A2.

      2. Do we have any information on the Host Wake Signal operation in USB mode?

      3. Do we have any information on the electrical specification for the Host Wake signal. is it open collector?

      4. The customer has followed our reference design, which should allow them to inherit the Bluetooth QID. Do they inherit the certification (FCC CE etc) or what do they need to do to simplify this process?

       

      Thanks
