Dear Sirs and Madams,

 

We understand that the CapSense components of PSoC4S are fourth-generation.

The AN85951 CSD(Self) and CSX(Mutual) has been described as up to 200pF as follows.

In addition, the description of the CapSense component datasheet has the following description.

Cp of CSD is up to 61pF.

From the above, both CSD(Self) and CSX(Mutual) does not mean support Cp of up to 200pF, I understand that  fourth-generation CSD is up to 61pF and CSX is up to 200pF. Is this recognition correct?

Or does CSD Auto mean up to 61pF and CSD Manual mean up to 200pF?

 

Regards,

It means the Cp ranges from 5pf to 61 pf when using the auto smart tuning mode. 

But it ranges from 5pf to 200pf when using manual mode.

Thank you for answering my question.

I was misunderstanding about the maximum value of Cp.
