6 / 31 page  CY8CMBR2010 Document Number: 001-74495 Rev. *A Page 6 of 31 Configuring the CY8CMBR2010 The CY8CMBR2010 device features are configured using external resistors. The resistors on the hardware configurable pins are determined by the device upon power-on. The Appendix on page 28 gives the matrix of features enabled using different external resistor configurations. To know more about the required settings for your design, refer to the CY8CMBR2010 Design Guide. Device Features CapSense Buttons ■ Supports up to ten CapSense buttons. ■ Ground the CSx pin to disable CapSense button input. ■ A 2.2 nF (±10%) capacitor must be connected on the CMOD pin for proper CapSense operation. ■ For proper CapSense operation, ensure CP of each button is less than 40 pF. SmartSense™ Auto-Tuning ■ Supports auto-tuning of CapSense parameters ■ No manual tuning required; all parameters are automatically tuned by the device. ■ Reduces the design cycle time. ❐ No manual tuning. ■ Ensures portability of the user interface design. ■ Compensates Printed Circuit Board (PCB) variations, Device process variations, and PCB vendor changes. General-Purpose Outputs ■ GPOx pin outputs are strong drive[3] ■ The GPOx is controlled by the corresponding CSx ■ Active low output – supports sinking configuration for LEDs (see Figure 3) ■ If CSx is disabled (grounded), then the corresponding GPOx must be left floating ■ A 5-ms pulse is sent after 350 ms (if Noise Immunity level is “Normal”) / 1000 ms (if Noise Immunity level is “High”) after power-up on the GPOx if the CSx fails the System Diagnostics Figure 3. Example of GPO0 Driven by CS0 CS0 GPO0 Sensor Touched Sensor Released Button Button Table 2. Advanced Features Supported by CY8CMBR2010 Feature Benefit Toggle ON/OFF Button retains state on touch (ON/OFF) Flanking Sensor Suppression (FSS) Helps in distinguishing closely spaced buttons Noise Immunity Improves device immunity to external noise (such as RF noise) LED ON Time Gives an LED effect on button release Button Auto Reset Disables false output trigger, due to conducting object placed close to button Power-on LED Effects Provides visual effects to design at power-on Analog Voltage Support External resistors can be used with GPOs to generate analog voltage output LED Backlighting Common GPO available for LED drive if Analog Voltage Support enabled Sensitivity Control for CS0 Button and Debounce Control for CS0 Button Useful for special function buttons such as power button System Diagnostics Support for production testing and debugging Serial Debug Data Support for production testing and validating design Low Power Sleep Mode and Deep Sleep Mode Low power consumption Note 3. When a pin is in strong drive mode, it is pulled up to VDD when the output is HIGH and pulled down to Ground when the output is LOW. |
