32.1 Features

  • Low-Power, High-Sensitivity, Environmentally Robust Capacitive Touch Buttons, Sliders, Wheels and 2D Surface
  • Supports Mix-and-Match Mutual Capacitance and Self-Capacitance Sensing
    • Supports 11/17/23/27 PTC pins for the 14-/20-/28-/32- pin variants, respectively
  • Supports Lumped Mode that allows the Integration of Multiple Sensors, Configuring them to function as a Single Sensor
  • One Pin per Electrode – No External Components
  • Load Compensating Charge Sensing:
    • Parasitic capacitance compensation
    • Adjustable gain for superior sensitivity
  • Zero Drift Over the Temperature and VDD Range:
    • Auto-calibration and recalibration of sensors
  • Hardware Noise Filtering and Noise Signal Desynchronization for High-Conducted Immunity
  • Supports Analog Accumulation. Digital accumulation supported with ADC interface
  • Driven Shield+ for Superior Noise Immunity and Moisture Tolerance
    • Any PTC X/Y line can be used for the driven shield
  • Supports External Integration Capacitors (EXTCINT) for Large Capacitance Sensors
  • Boost Mode for Doubled Signal-to-Noise Ratio or 4x Faster Response Time in Mutual Capacitance Systems
  • Uses ADC Peripheral for Signal Conversion and Acquisition
  • Supported by the MPLAB® Code Configurator (MCC) Touch Configurator Development Tools
