PSoC® CapSense

Enables Efficient Design of Capacitive Sensor Scan Applications

Simple. Flexible. Integrated.   CapSense. Capacitive sensing replaces mechanical buttons, switches, sliders, and proximity detectors in systems from cell phones and cars to notebooks, PCs, white goods and industrial applications. Immune to environmental wear-and-tear, Cypress's cost-effective CapSense solution leverages the flexibility of our configurable PSoC mixed-signal array and brings elegance, economy and functionality to your designs.

PSoC(R) CapSense takes advantage the unique features of the PSoC to enable efficient design of capacitive sensor scan applications. These features include wide analog MUX allowing all channels to be serviced by a common comparator and current source, internal programmable current source, and automatic connection of comparator to sensor discharge switch.

The PSoC architecture allows designers to incorporate multiple capacitive sensing design elements into an application. Buttons, sliders, touchpad’s and proximity detectors are supported simultaneously with the same device in the same circuit. Internal hardware eliminates the need for external components to set charging current or to calibrate sensitivity.

The flexibility of PSoC and CapSense allows designers to move across platforms and adapt to design changes quickly. All calibration is completed in software through an easy-to-use, graphical development environment. Application changes do not require migration to other devices because PSoC is highly configurable.

Non-CapSense applications are easily accomplished using PSoC's digital and analog resources. Use PSoC to scan switches and use the activation status to drive LEDs, control a motor, drive a speaker, etc.     Free CapSense Web Seminar
