CY8C20xx7 device family supports water tolerance applications
Does the CY8C20xx7 device family support water tolerance applications?
Yes, the CY8C20xx7 device family supports shield electrodes on 5 ports pins. Each shield electrode can be enabled independently from other shield electrode. Maximum parasitic capacitance of shield electrode should be less than 100pF for a 3MHz sensor scan clock for the shield electrode to work perfectly. The shield electrode feature in CY8C20xx7 is ideal for implementing:
- Water tolerant buttons and sliders,
- Buttons and sliders in presence of metal objects and
- Proximity sensors.
