Hello,

in our application we're using a CY8CMBR3108-LQXI, but we'd like to add some features to the cap input pins (and control them as GPIO).

We've seen the CY8C4014LQI-421 (a PSOC4 MCU) is pin-to-pin compatible.
Is there any difference on the performance of the capacitive inputs of the two devices?

In theory should be possible to create an ad-hoc software for PSOC4 to behave similarly to the MBR. Is there an already available source code to avoid starting from scratch?

Thank you!

Hi @rc_user ,

CY8C4014LQI-421 is a PSoC 4000 part and uses older CapSense IP. I recommend you use a PSoC 4000S device. PSoC 4 S series devices are the newer devices in PSoC 4 lineup. This uses fourth-generation CapSense and is more robust.

There are many code examples present for PSoC 4. You may use these as references to build your application thereon. You may start with PSoC Creator or ModusToolbox as your development IDEs. You may access these code examples in the following ways:

Thank you Nikhil,

unfortunately there isn't any PSOC 4000S with 16 pins or less 😞

We've already validated CY8CMBR3108-LQXI for our applications and it works really well. Is the Capsense technology used in this MBR partnumber the same of PSoC 4000?

RC

Hi @rc_user,

If you have a strict requirement for a 16-pin package, then you may go ahead with PSoC 4000. Otherwise, I suggest you use CapSense devices with 4th generation CapSense or higher.

The performance of MBR devices and PSoC4000 would be the same.

Nikhil
