PSoC 6 CapSense design

Posted by ShanmathiN_06 Jul 11, 2018

Hello everyone!


Here is some information on how to design CapSense sensors while developing Capacitive sensing applications in PSoC 6.


Schematic design:

After selecting PSoC device, while designing schematic you can refer to the following documents:


1) PSoC 6 datasheet (depends on the selected device)

2) Schematic Rule checklist section in AN85951 - PSoC 4 and PSoC 6 MCU CapSense Design Guide (

3) AN218214 - Hardware design considerations (

Layout design:

While designing PCB, refer to the following documents:


1) Design considerations section in AN85951 - PSoC 4 and PSoC 6 MCU CapSense Design Guide (

2) Specifically, layout rule checklist section in AN85951

3) For proximity sensor design, refer to AN64846 - Getting Started with CapSense ( and AN92239 - Proximity Sensing with CapSense (


Following the above mentioned guidelines in various documents will help achieve high SNR, better performance and electromagnetic compatibility.

Hello PSoC MCU Developers!

One of our very own Field Apps Engineers, Darrin Vallis has worked with Express Logic to implement the world’s most adopted RTOS, ThreadX, on a PSoC 6 MCU using its native IDE, PSoC Creator. ThreadX, part of the X-WARE IoT PLATFORM, is a high-performance RTOS, best-suited for safety critical designs in areas such as aviation, medical, and industrial.
