Application Notes:
The Atmel(R) AT42QT1050 is a QTouchADC(TM) sensor driver. The device can sense from one to five keys, dependent on mode. The QT1050 includes all signal processing functions necessary to provide stable sensing under a wide variety of changing conditions, and the outputs are fully debounced. Only a few external parts are required for operation and no external Cs capacitors are required. The QT1050 modulates its bursts in a spread-spectrum fashion in order to heavily suppress the effects of external noise, and to suppress RF emissions. The QT1050 uses a QTouchADC method of acquisition. This provides greater noise immunity and eliminates the need for external sampling capacitors, allowing touch sensing using a single pin.
- Configurations: Comms mode
- Number of Keys: 1 to 5 keys (or 1 to 4 keys plus a Guard Channel)
- Technology: Patented spread-spectrum QTouchADC charge-transfer
- Key Outline Sizes: 6 mm × 6 mm or larger (panel thickness dependent); widely different sizes and shapes possible
- Layers Required: One
- Electrode Materials: Etched copper; Silver; Carbon; Indium Tin Oxide (ITO)
- Panel Materials: Plastic; Glass; Composites; Painted surfaces (low particle density metallic paints possible)
- Up to 10 mm glass (electrode size dependent)
- Up to 5 mm plastic (electrode size dependent)
- Key Sensitivity: Individually settable using simple commands over I2C interface
- Interface: I2C slave mode (400 kHz). Discrete detection outputs
- Self-calibration
- Auto-drift compensation
- Noise filtering
- Adjacent Key Suppression® (AKS®) – up to three groups possible
- Moisture Tolerance: Increased moisture tolerance based on hardware design and firmware tuning
- Power Saving: Low Power (LP) mode supports both Low Power and Deep Sleep modes
- Power: 1.8 V to 5.5 V
- 12-ball WLCSP RoHS-compliant IC
- 20-pin VQFN RoHS-compliant IC
