It is a register-configurable device and does not require any firmware coding or device programming. In addition, this device is enabled with Cypress’s SmartSense Auto-Tuning algorithm which elimi- nates the need to manually tune the user interface during devel- opment and production ramp. This speeds the time to volume and saves valuable engineering time, test time, and production yield loss. The EZ-Click Customizer tool is a simple graphical interface for configuring the device features, through the I2C interface. One configuration can be used to configure multiple samples in different boards. The CY8CMBR2110 CapSense controller supports up to ten capacitive sensing buttons and ten GPOs. The GPO is an active low output controlled directly by the CapSense input making it ideal for a wide variety of consumer, industrial, and medical appli- cations. The wide operating range of 1.71 V to 5.5 V enables unregulated battery operation, further saving component cost. The same device can also be used in different applications with varying power supplies. This device supports ultra low-power consumption in both run mode and deep sleep modes to stretch battery life. In addition, this device also supports many advanced features, which enhance the robustness and user experience of the end solution. The key advanced features are Noise Immunity and Flanking Sensor Suppression (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. Power-on LED effects provide visual feedback to the design at system power-on. Button-controlled LED effects provide visual feedback on a button touch. These effects improve the aesthetic value of the end product. Buzzer Signal Output provides audio feedback on a button touch. System diagnostics test for design faults at power-on and report any failures. This simplifies production-line testing and reduces manufacturing costs. CapSense data output through I2C gives critical information about the design, such as button CP and signal-to-noise ratio (SNR). This further helps in system debug and production-line testing. Note 1. 23 µA per button (4 buttons used, 180 button touch per hour, average button touch time of 1000 ms, buzzer disabled, Button Touch LED Effects disabled, 10 pF < CP of all buttons < 20 pF, Button Scan Rate = 541 ms, with power consumption optimized, Noise Immunity level Normal, CSx sensitivity Medium). |
