User Module Datasheet: CapSenseĀ® Sigma-Delta Datasheet CSD V 1.70 (CY8C21x34, CY8CLED04)

Last Updated: 10/22/2012
Version: 1.80


Features and Overview

  • Scan 1 to 28 capacitive sensors.
  • Sensing possible with up to a 15 mm glass overlay.
  • Proximity detection to 20 cm with a wire-based sensor.
  • High immunity to AC mains noise, EMC noise, and power supply voltage changes.
  • Supports different combinations of independent and slide capacitive sensors.
  • Double slide sensor physical resolution using diplexing.
  • Increase slide sensor resolution using interpolation.
  • Touchpad support with two slide sensors.
  • Sensing support through high resistive conductive materials (ITO films for example).
  • Shield electrode support for reliable operation in the presence of water film or droplets.
  • Guided sensor and pin assignments using the CSD Wizard.
  • Integrated baseline update algorithm for handling temperature, humidity, and electrostatic discharge (ESD) events.
  • Easily adjustable operational parameters.
  • PC GUI application support for raw data monitoring and parameter optimization in real time.
     

Capacitive sensing using a sigma delta modulator (CSD) provides CapSense® functionality using a switched capacitor technique with a sigma-delta modulator to convert the sensing switched capacitor current to digital code.
