Cypress CapSense® Capacitive Touch Sensing Technology

Buttons, switches, sliders and proximity sensors integrated into CapSense controllers, PSoC programmable systems-on-chip, and USB-Serial bridge controllers

Integrated touch-sensing user interfaces are replacing mechanical buttons and knobs everywhere. State-of-the-art products need a sophisticated and elegant user interface solution that works reliably in wet, electrically noisy conditions and complies with rigorous IEC 61000 generic standards for noise immunity and emissions. CapSense technology does all this. Cypress offers a range of devices integrating CapSense with LED and LCD control, sensor interfaces, system monitoring, USB-Serial bridging and many other system functions.

CapSense technology features include:

  • 1 – 44 CapSense I/Os available for configuring buttons, sliders and proximity sensors
  • Easy-to-use configurable options that require no programming know-how
  • Fully-programmable options for power users wanting detailed control
  • QuietZone™ technology for immunity to radiated and conducted noise
    • Superior signal-to-noise ratio (SNR) in all conditions with CSDPLUS sensing method
    • Sensitivity to finger capacitance changes as low as 0.1 pF, supporting 15 mm glass and 5 mm plastic overlays
  • Cypress’s SmartSense™ Auto-Tuning algorithm, which continuously compensates for system, manufacturing, and environmental changes during run-time
  • Fully-tested solutions for features such as proximity sensing and water tolerance
  • Ultra-low power with industry's widest voltage range: 1.8 V – 5.5 V
  • Multiple memory and footprint options for easy device selection
