Cypress provides a complete ecosystem to enable a quick devel-

opment cycle with the CY8CMBR3xxx CapSense controller 

family. This ecosystem includes simple tools for device configu-

ration, design validation, and diagnostics.

Design guides are an excellent introduction to a variety of 

possible CapSense-based designs. They provide an intro-

duction to the solution and complete system design guidelines. 

Refer to the following design guides for CY8CMBR3xxx: 

1.

 – an ideal starting point for all 

CapSense users

2.

 – provides 

complete system design guidelines for CY8CMBR3xxx

You can download these design guides from our website: 

The CY8CMBR3xxx 

 lists and details all the 

registers of the CY8CMBR3xxx family of controllers in order of 

their addresses. These registers may be accessed through an 

I

2

C interface with the host.

The 

 is a simple, GUI-based software 

utility that can be used to customize the CY8CMBR3xxx device 

configurations. 
Use this GUI-based tool to do the following:

■

Select the appropriate part number based on an 

end-application requirement using the Product Selector

■

Configure the device features 

■

Observe CapSense data for button and proximity sensors

■

Use the System Diagnostics and built-in test self-test (BIST) 

features for debug and production-line testing

The 

 is an interactive spreadsheet tool that 

provides application-specific design guidelines for capacitive 

buttons. It is used to configure and validate the CapSense 

system. 
The Design Toolbox:

■

Provides general layout guidelines for a CapSense PCB

■

Estimates button dimensions based on end-application 

requirements

■

Calculates power consumption based on button dimensions

■

Validates layout design

The 

 can be used to quickly 

evaluate the various features of the CY8CMBR3xxx solution. 

The kit also functions as an Arduino shield, making it compatible 

with the various Arduino-based controllers in the market. You can 

purchase this kit at the 

. 

In addition to print documentation, there are abundant web 

resources. The dedicated 

 for the CY8CMBR3xxx 

family has all the current information. 

Free PSoC and CapSense technical training (on-demand, 

webinars, and workshops) is available online at 

. The training covers a wide variety of 

topics and supports different skill levels to assist you in your 

designs.
