CapSense® Express™ Controllers with SmartSense™ Auto-tuning 16 Buttons, 2 Sliders, Proximity Sensors
General Description
The CY8CMBR3xxx CapSense® Express™ controllers enable advanced, yet easy-to-implement, capacitive touch sensing user
interface solutions. This register-configurable family, which supports up to 16 capacitive sensing inputs, eliminates time-consuming
firmware development. These controllers are ideal for implementing capacitive buttons, sliders, and proximity sensing solutions with
minimal development-cycle times.
The CY8CMBR3xxx family features an advanced analog sensing channel and the Capacitive Sigma Delta PLUS (CSD PLUS) sensing
algorithm, which delivers a signal-to-noise ratio (SNR) of greater than 100:1 to ensure touch accuracy even in extremely noisy
environments. These controllers are enabled with Cypress’s SmartSense™ Auto-tuning algorithm, which compensates for
manufacturing variations and dynamically monitors and maintains optimal sensor performance in all environmental conditions. In
addition, SmartSense Auto-tuning enables a faster time-to-market by eliminating the time-consuming manual tuning efforts during
development and production ramp-up.
Advanced features, such as LED brightness control, proximity sensing, and system diagnostics, save development time. These
controllers enable robust liquid-tolerant designs by eliminating false touches due to mist, water droplets, or streaming water. The
CY8CMBR3xxx controllers are offered in a variety of small form factor industry-standard packages.
The ecosystem for the CY8CMBR3xxx family includes development tools—software and hardware—to enable rapid user interface
designs. For example, the EZ-Click Customizer tool is a simple graphical user interface software for configuring the device features
through the I2C interface. This tool also supports CapSense data viewing to monitor system performance and support validation and
debugging. Another tool, the Design Toolbox, simplifies circuit board layout by providing design guidelines and layout
recommendations to optimize sensor size, trace lengths, and parasitic capacitance. To quickly evaluate the CY8CMBR3xxx family
features, use the CY3280-MBR3 Evaluation Kit.

System Overview
A capacitive sensor detects changes in capacitance to determine
the presence of a touch or proximity to conductive objects. The
capacitive sensor can be a capacitive button that replaces the
traditional mechanical buttons, a capacitive slider that replaces
mechanical knobs, or a proximity sensor that replaces an
infrared sensor in a user interface solution. A typical capacitive
user interface system consists of the following:
■ A capacitive sensor
■ An audio-visual output, such as a buzzer or an LED
■ A capacitive sensing controller connected to the sensor
■ A host processor
The capacitive controller connects the sensor and the output to
the host processor through a communication interface, such as
an I2C or a GPO.
The capacitive user interface system serves as a
human-machine interface that takes the user’s touch inputs and
provides audio-visual feedback through a buzzer or an LED.
CY8CMBR3xxx is a family of capacitive sensing controllers,
which senses the change in capacitance based on touch or
proximity, and controls the user interface system accordingly.
The sensing algorithm, built in the controllers, determines the
presence of touch and drives the outputs or sends signals to the
host processor. This algorithm can distinguish between the
signal (based on touch or proximity) and noise, which can be
caused by environmental or electrical conditions.
Figure 2 shows a typical user interface system with capacitive
buttons connected to a CY8CMBR3xxx CapSense Express
controller, which controls the system and also communicates
with the host processor through I2C.
Traditionally, capacitive sensing controllers require firmware
development to perform specific user interface functions and
manual system tuning to achieve optimal performance.
However, the CY8CMBR3xxx CapSense Express family of
controllers does not require any firmware development, acceler-
ating time-to-market. These devices feature SmartSense
Auto-tuning, which eliminates the need for manual tuning,
providing optimal performance even under extremely noisy
conditions.
