Features and Overview
-
Implements CapSense® capacitive sensing in the CY8C20xx6L family of PSoC® devices using the sigma-delta data conversion
-
Immune to GPIO current transient, VDD fluctuation, entry and exit from sleep, and IDAC RTS noise
-
Configurable system parameters enable tuning so that performance is optimized in a broad range of applications
-
Supports up to 36 capacitive sensors and 6 sliders
-
Capable of detecting 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
-
Supports capacitive sensors configured as independent buttons and as dependent arrays to form sliders
-
Effective numbers of slider elements can double the number of dedicated I/O pins using the diplexing technique
-
Supports slider resolution greater than the physical pitch through interpolation
-
Gives shield electrode for reliable operation with high parasitic capacitance and in the presence of a water film
-
Guided sensor and pin assignments using the CSDe Wizard
