I have seen this posting: What's the difference between CYW20719B2 and CYW20719B1?
But the information referenced there does not seem to be complete. Specifically it looks like the POR State of some pins may have changed in the B2 version of the chip?
After swapping the B2 chip into my design it seems that at least P33 defaults to a logic 'high' on POR?
Is there an official, comprehensive listing of the changes in the B2 version of the chip?
Solved! Go to Solution.

That reference really focuses more on the difference between API's in Modus ToolBox and WICED Studio, ... it doesn't really describe what is different between the B1 and B2 silicon.

The only difference document we have is this blog. CYW20719B1 and B2 are pin to pin compatible. We will need to check if there is any difference in pin status. Can you please get in touch with your local Cypress team for more information on this?
