I can't understand the differences between CY7C65642 and CY7C65640A. Someone can help me?
The 65640 is not recommended for new designs which means it will become obsolete within the next time.
There is an Appnote showing how to migrate to 64642 which is showing the differences as well.
Look here: http://www.cypress.com/?rID=52716
Both are multi-TT hubs i.e. same function different flavors.
Tank you very much.
