is csa only embeded into Cy8C20x34?

[befic_2639911]

Hi,everyone.

     CapSense can be CSA or CSD. From Datasheet, I found many cypress SOCs has the Capsense with CSD in it.

     Then which SOC was embeded witch CSA?

      And what is the CSD advantage over CSA?

     is there any toolbox for such SOCs with CSA to tune all parameters? for example, an guideline file,"CY8CMBR2016 CapSense MBR Design Toolbox for 16 buttons". but it is based on CSD.

CSA EMC is available on CY8C20x34, CY8C20x24, CY8C20x66, CY8C20x36, CY8C20336AN, CY8C20436AN, CY8C20636AN, CY8C20xx6AS, CY8C20x46, CY8C20x96, CYONSFN2053, CYONSFN2061, CYONSFN2151, CYONSFN2161, CYONSFN2162, CYRF89435, CY8C20065.

You can get to know further details on CSA in Resources Available for CapSense® Controllers - KBA92181. I suggest that your use PSoC4 for your CapSense Applications, as PSoC1 is a mature family.

Thank you very much!

So kind of you to give me so many resources.

Now I got cy8ckit-145 board, and I can monitor the raw count .But I am not clear how the raw count is calculated? From a datasheet,I got a formula，like that:

raw count = (2^N-1)*Vref*Fsw*Cs/Imod. it is in AN85951.

while in the KBA82522 in this community, there is such a formula.

which is right? How to get it?

And what is raw count formula about CSA?

[SampathS_11 · Accepted solution]

The equation for raw counts for CSA UM is

AN85951 is for PSoC4, while KBA82522 is for PSoC1.

If you are having CY8CKIT-145, you should follow AN85951.
