CY8CMBR3110/CY8CMBR3116 Datasheet  
The CY8CMBR3xxx family offers liquid-tolerance to liquids such  
as water, ketchup, oil, and blood.  
Features Overview  
CapSense Sensors  
Enable the shield electrode through the register map, using  
EZ-Click, to prevent false touches under wet conditions and  
enable both the shield electrode and guard sensor to prevent  
false touches in streaming water conditions. The shield electrode  
and guard sensor consume a port pin each in the CapSense  
controller. Refer to the CY8CMBR3xxx CapSense Design Guide  
for best practices and design guidelines for implementing  
liquid-tolerant designs.  
The CY8CMBR3xxx family of controllers supports up to 16  
capacitive sensors. These can be configured as follows:  
Up to 16 CapSense buttons  
Up to two sliders: Configurable as linear or radial sliders  
Up to two proximity sensors that can detect up to 30-cm  
proximity distance  
Noise Immunity  
Sliders  
The CY8CMBR3xxx family features the robust CSD PLUS  
capacitive sensing algorithm. Additionally, it implements the  
advanced noise immunity algorithm, EMC, for stable operation  
in extremely noisy conditions.  
Supports up to two 5-segment sliders  
Configures each slider individually as linear or radial  
Combines both sliders to form one 10-segment slider  
Slider resolution is user-configurable  
The EMC algorithm has higher average power consumption. For  
low-power applications, where noise conditions are not extreme,  
you can disable this feature through the I2C interface.  
Proximity Sensors  
Flanking Sensor Suppression (FSS)  
The CY8CMBR3xxx family supports up to two proximity  
sensors with a detection range of up to 30 cm. These proximity  
sensors are capable of detecting both proximity and touch  
events.  
This feature distinguishes between signals from closely spaced  
buttons, eliminating false touches. It ensures that the system  
recognizes only the first button touched.  
Touch Feedback  
The wake-on-approach feature wakes the devices from a

audio-visual feedback through a buzzer or an LED.  
low-power state to Active mode on a proximity event.  
The device also features driven shield, which enhances the  
proximity sensing range in the presence of metal objects.  
General-Purpose Outputs (GPOs)  
The device supports proximity sensors with CP ranging from  
8 pF to 45 pF.  
The GPOs are high-sink current outputs that can drive most  
LEDs. The GPO status can be controlled directly by the  
CapSense sensors so that a sensor 'ON' status automatically  
turns ON a corresponding LED. Alternatively, GPOs can be  
controlled by the host through the I2C interface.  
SmartSense Auto-tuning  
The CY8CMBR3xxx family features SmartSense Auto-tuning,  
Cypress's patented CapSense algorithm, which continuously  
compensates for system and environmental changes during run  
time. SmartSense Auto-tuning has the following advantages:  
The GPOs also support advanced features, such as:  
CSx to GPOx Direct Drive: Directly control the GPOs upon  
button touch or proximity event.  
Reduces design effort by eliminating manual tuning  
Pulse width modulation (PWM): Controls LED brightness.  
Adapts to variations in PCB, overlay, paint, and manufacturing  
that degrade touch-sensing performance  
Toggle: The GPO status is toggled upon every touch event on  
the button sensors, and proximity event on proximity sensors,  
to mimic the functionality of the mechanical toggle switch.  
Eliminates manual tuning in production  
Adapts to changes in the system environment due to noise  
Voltage output: Analog voltage that represents the button  
status.  
Allows a platform design approach with different overlays,  
button shapes, and trace lengths  
Buzzer Drive  
The output pins of the CY8CMBR3xxx controllers can be  
configured for driving a single-input DC Piezo-electric buzzer  
through a PWM. The PWM frequency and buzzer activation  
duration are configurable. The buzzer output is activated for a  
finite amount of time when a finger touch is detected.  
Liquid Tolerance  
The CY8CMBR3xxx family delivers water-tolerant designs that  
eliminate false touches due to wet conditions, such as water  
droplets, moisture, mist, steam, or even wet hands. The  
CapSense controller locks up the user interface in firmware to  
prevent touch inputs in streaming water.
