Description
The user interface of a product is a key element that design engineers need to address to provide a compelling user experience. Touchpads, slides and rotaries offer a more intuitive and effective way of user interaction than traditional buttons. And, designing a touch-based user interface is simplified with this NXP touch solution.
The touch function is more and more popular in the consumer market, especially in the white-good field. The KE15Z series of MCUs offers the Touch Sensing Interface (TSI) which recognizes finger touch by sensing capacitance changes.
Features
- Advanced EMC robustness, pass IEC61000-4-6 standard test
- Supports both self-cap sensor and mutual-cap sensor, up to 36 touch keys
- Low BOM cost per touch key, no need for external devices
- Adjustable touch sensing resolution and sensitivity, high-performance for waterproof applications
- Low-power support
