Features and Overview
-
Implements CapSense® capacitive sensing in the CY8C20xx6A family of PSoC® devices using sigma-delta data conversion.
-
Configurable system parameters allow tuning to optimize performance 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, detecting a finger is possible 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/or as dependent arrays to form sliders.
-
Effective number of slider elements can double the number of dedicated I/O pins using diplexing technique.
-
Supports slider resolution greater than physical pitch through interpolation.
-
Shield electrode provided for reliable operation with high parasitic capacitance and/or in the presence of water film.
-
Guided sensor and pin assignments using the CSD Wizard.
-
The CY8C20045 family does not support sliders.
