I think PSoC4100S series don't have IMO Frequency Spread function.

Is it correct?

If yes, why was the function deleted?

Best Regards,

Inoue

Hi Inuoe-san,

CY8C4146LVA-S432 doesn't have IMO spread feature.

If the customer wants to reduce CapSense emissions, then they can use PRS or Spread spectrum in CapSense.

I am sorry for lack of explanation.

IMO Frequency Spread is described in the document "PSoC 4100/4200 Family PSoC® 4 Architecture TRM"

Hello,

For the reason why IMO Frequency Spread function isn't in PSoC4100S, please refer to Advantages of Fourth-Generation CapSense® – KBA211132​. Specially for the Feature of EMI Reduction - Digital in the table.

4th Generation CapSense (in PSoC 4-S, i.e. PSoC4100S) itself already has spread spectrum and hence spreading IMO not needed.
