Features and Overview

  • Implements CapSense® capacitive sensing in the CY8C20xx7S family of PSoC® devices
  • Auto-tunes configurable system parameters in runtime to account for sensor, IC, and PCB characteristics
  • Supports as many as 35 capacitive sensors and six sliders
  • Supports parasitic sensor capacitance range of 5 pF to 45 pF
  • Detects touches as low as 0.1 pF, that is, a finger touch can be detected through up to 15 mm of glass or 5 mm of plastic
  • High immunity to AC mains noise, other EMI, and power supply noise
  • Supports capacitive sensors configured as independent buttons and also as dependent arrays to form sliders
  • Provides diplexing option, which enables two linear slider elements to be assigned per dedicated I/O pin
  • Supports slider resolution greater than physical pitch through interpolation
  • Provides shield electrode for reliable operation with high parasitic capacitance and in the presence of water film
  • Enables guided sensor and pin assignments using the SmartSense_EMCplus™ Wizard
  • The SmartSense Electromagnetic Compatible (SmartSense_EMCplus) User Module provides superior noise immunity against external noise
Note: This user module supports only C language projects: Assembly language (ASM) projects are not supported.
