I used CY8C20437 for touch control in current project . I plan to use CY8C20436A due to cost considering.
I checked the data sheet of both. the major different of them is CY8C20437 has proximity sensing , CY8C20436A hasn't.
but I did not use proximity sensing in my project. So my question is , is there any other big different of touch function between them beside proximity sensing . Thank
