Key Features
- CapTIvate™ Technology: Supports capacitive touch sensing with up to 8 self-capacitance and 16 mutual-capacitance electrodes.
- Performance: Fast electrode scanning with two simultaneous scans, proximity sensing, and high reliability with increased immunity to power line, RF, and other environmental noise.
- Noise Immunity: Built-in spread spectrum, automatic tuning, noise filtering, and debouncing algorithms ensure reliable touch solutions even in harsh environments.
- Low Power Consumption: Less than 4 µA wake-on-touch with two sensors, and a wake-on-touch state machine that allows electrode scanning while the CPU is asleep.
- Flexibility: Supports multi-touch functionality and a wide range of capacitance detection (0 to 300 pF).
- Ease of Use: CapTIvate Design Center and CapTIvate software library in ROM simplify the design and tuning process without requiring extensive coding.
- Environmental Robustness: Supports touch through glass, plastic, and metal overlays and offers water rejection designs.
