CYW4343W, 8, 9 differences

[GrCa_1363456]

What are the specific differences between the original CYW43438/W and the newer CYW43439?

The packages all seem to be unique along with the specific GPIO that is brought out. This isn't a big issues as those difference will be obfuscated from a certified module perspective.

The CYW43439 appears to have dropped the I2S interface.

Are there any other differences?

@GrCa_1363456 are you looking at a comprehensive document(not sure if its ready/available yet) explaining what all changed between 43430 and the 43439 or are you looking looking at specifics? If specifics can you let me know which are those for me to put it out here?

Murali,

Thanks for the quick response. 

Customers are asking in general, "What are the main differences between the 4343W, 43438,  and 43439 ?" I interpret that as functions added or removed.

I would also like to know technical (process technology, interface timing changes).

I understand drop in replacement / compatibility questions will be for the module partners. I'm glad to see links to Partner Modules starting to show up on Infineon's Radio Silicon sites such as https://www.infineon.com/cms/en/product/wireless-connectivity/airoc-wi-fi-plus-bluetooth-combos/cyw4...
