1. Introduction
Thank you for your interest in the CY3280-MBR3 Evaluation Kit (EVK). This kit is designed to showcase the abilities of the CY8CMBR3116 register-configurable CapSense
®
controller. It is also
designed as an Arduino™-compatible shie ld that supports various Arduino baseboards as well as
other stackable shields available in the market. The CY3280-MBR3 EVK features four CapSense
buttons, one proximity sensor loop, LEDs, a buzzer, and an onboard USB-I
2
C bridge to communi-
cate with the EZ-Click™ 2.0 customizer tool, which configures the CY8CMBR3xxx controller.
The CY8CMBR3xxx series is the latest addition to the register-configurable CapSense Mechanical
Button Replacement (MBR) family of solutions. The CY8CMBR3xxx family of controllers enables
you to quickly and easily add capacitive touch sensin g to your user interface. See Configuring the
CY8CMBR3116 Controller Using EZ-Click 2.0 on page 21 for information on how to configure a
CY8CMBR3116 controller. CY3280-MBR3 offers the best feat ures of Cypr ess’ CapSen se in a small
package that is easy to implement and configure. Coupled with the Capacitive Sigma Delta PLUS
(CSD PLUS) sensing algorithm and the patented SmartSense™ Auto-Tuning feature, the
CY8CMBR3xxx controller provides a robust capacitive sensing solution, with up to 16 CapSense
inputs.
SmartSense Auto-Tuning has the following advantages:
■ Reduces design effort by eliminating manual tuning
■ Adapts to variations in PCB, overlay, paint, and manufactu ring that degrade touch-sensing per-
formance
■ Eliminates manual tuning in production
■ Adapts to changes in the system environment due to noise
■ Allows a platform design approach with different overlays, button shapes, and trace lengths
The MBR3 solution delivers a high signal-to-noise ratio (SNR) even in extremely noisy environments
and maintains optimal sensor performance at run time. The driven shield capability offers robust
proximity sensing and water tolerance, enabling its use in a wide range of applications. The MBR3
solution supports register configurability and SmartSense Auto-Tuning features, which allow customers to gain a faster time-to-market for their end product.
The CY8CMBR3xxx family of controllers is designed with multiple low-power operational states to
meet the low-power requirements of battery-powered applications. These controllers have the following operational states: Boot, Active, Look-for-Touch, Look-for-Proximity, Deep Sleep, and Configuration. The CY8CMBR3xxx controllers automatically manage transitions between the four states.
The Look-for-Proximity state allows ultra-low power consumption whe n a hu man bod y is not in close
proximity. This state is entered only if the wake-on-approach feature is enabled (and toggle is disabled) in the MBR3 register configuration, which can be done using the EZ-Click 2.0 customizer tool.
Refer to the MBR3 device datasheet for more details on the CY8CMBR3xxx family of CapSense
controllers.
The kit package includes the EZ-Click 2.0 customizer tool, which is required to co nfigur e the kit. For
more information and to download the tool, visit the EZ-Click Customizer page.
