Yes that is true… and the people that own that datasheet work for me now… so I suppose in this case it really is my problem 🙂

I hope Cypress figures out this would be a good feature to add in their datasheets.
Meanwhile, yes, we can use the PSOC Creator to validate our choices.

The 4100 family is CSD only… the 4100s has CSD & CSX … the one I looked at was CY8C4125axi-483

The part you picked is from the 4200 family. I created a schematic with 8C4245AZI-483 put in capsense… and it let me choose CSX.

Hope that helps.

Alan

It has been more than 2 years since that post, so the technology should be out by now. But when I look into the PSOC 41xx and 42xx datasheet, I see mention of CSD (self capacitance sense) but no mention of CSX (mutual capacitance sense). Could you confirm if these families should be able to use CSX? I had set my mind on the CYP-CY8C4245AZI-483, but I am starting to think my choice was wrong. Thanks for letting me know, as I am certain this answer will help many.

You are right… sorry about that… I sometimes loose track that I run inside versions in advance…

Incidentally they send me the new board today and it is great.

I appreciate your feedback and I’m sorry I wasted your time looking.

Alan

However, you should really note that this feature is only available in the preliminary 3.3 SP2.3 version of the PSoC Creator.

Took me a while to find out what is “wrong” with the release that I am using.
Thanks anyway, now I know.
