CY8CMBR2016  
CapSense® Express™ 16 Button Matrix  
Controller  
Capacitive Button Controllers  
■ Industrial temperature range: –40 °C to + 85 °C  
■ 48-pin QFN package (6 × 6 × 0.6 mm)  
Features  
■ Hardware Configurable Matrix CapSense® Controller  
❐ Does not require software tools or programming  
❐ 16 buttons can be configured individually or as a matrix  
❐ Supports 3x4 and 4x4 matrix configurations  
Overview  
The CY8CMBR2016 CapSense Express capacitive touch  
sensing controller incorporates several innovative features to  
save time and money to quickly enable a capacitive touch  
sensing user interface in your design. It is a hardware  
configurable device and does not require any software tools,  
firmware coding or device programming. This device is enabled  
with Cypress's revolutionary SmartSense™ auto-tuning  
algorithm. SmartSense™ auto-tuning ends the need to manually  
tune the user interface during development and production  
ramp. This speeds the time to volume and saves valuable  
engineering time, test time and production yield loss.  
■ Matrix Host Interface Communication  
❐ Industrystandardhostinterfaceprotocolsreuseexistinghost  
processor firmware  
• Key Scan Interface  
• Truth Table Interface  
❐ Encoded GPO Interface - minimizes number of pins required  
■ SmartSense™ Auto-Tuning  
❐ Maintains optimal button performance even in noisy  
environments  
The device supports up to 16 capacitive touch buttons that can  
be organized in any format, such as a matrix array. With its  
backward compatible key scan interface, it can enable users to  
achieve quick-to-market (retrofit) designs in large keypad  
applications such as fire alarm control panels, security systems,  
and door locks. Any application that requires up to 16 CapSense  
buttons can utilize CY8CMBR2016.  
❐ CapSense parameters dynamically set in runtime  
❐ Wide parasitic capacitance (CP) range (5–40 pF)  
❐ Saves time and effort in device tuning  
■ Noise Immunity  
❐ High sensitivity, low noise capacitive sensing algorithm  
❐ Strong immunity to RF and AC noise  
❐ Low radiated noise emission  
The wide operating range of 1.71 V to 5.5 V enables unregulated  
battery operation, further saving component cost. This device  
supports ultra low-power consumption in both run mode and  
deep sleep mode to stretch battery life. In addition, this device  
also supports many advanced features, which enhance the  
robustness and user interface of the end solution. Some of the  
key advanced features include Noise Immunity and FSS. Noise  
Immunity improves the immunity of the device against radiated  
and conducted noise, such as audio and radio frequency (RF)  
noise. FSS provides robust sensing even with closely spaced  
buttons. FSS is a critical requirement in small form factor  
applications.  
■ System Diagnostics of CapSense Buttons  
❐ Reports any faults at device power up  
❐ Button shorts  
❐ Improper value of modulating capacitor (CMOD  
)
❐ Parasitic capacitance (CP) out of range  
■ Advanced Features  
❐ Flanking Sensor Suppression (FSS) provides robust sensing  
even with closely spaced buttons  
❐ Buzzer Signal Output  
The CY8CMBR2016 provides three different host interface  
communication modes. These include the industry standard host  
interface protocols such as Key Scan Interface and Truth Table  
Interface. These two protocols reuse existing host processor  
firmware leading to easy conversion of existing mechanical  
buttons to CapSense. The third host interface communication is  
the Encoded GPO Interface with a 4-bit output, which minimizes  
the number of pins required for a button output. These three  
outputs are configurable which helps provide a wide variety of  
device usage in multiple applications.  
❐ Configurable sensitivity for all buttons  
❐ Interrupt line to host to indicate any CapSense button status  
change  
❐ Serial Debug Data out  
• Simplifies production line testing and system debug  
■ Wide operating range  
❐ 1.71–5.5 V  
❐ Ideal for both regulated and unregulated battery  
applications [1]  
Serial Debug Data output gives the critical information about the  
design, such as button Cp and raw counts. This further helps in  
production line testing.  
■ Low power consumption  
❐ Supply current in run mode as low as 20 µA[2] per button  
❐ Deep sleep current: 100 nA  
Notes  
1. Supply variation should not be more than 5% for proper CapSense operation  
2. Power consumption calculated with 250 ms scan time, 2% touch time and C of each button < 19 pF.
