11-key QTouch® Touch Sensor IC
Features
DATASHEET
Sensor Keys: Up to 11 QTouch® channels
Data Acquisition: Measurement of keys triggered either by a signal applied to the SYNC pin or at
regular intervals timed by the AT42QT1110 internal clock Keys measured sequentially for better performance, or in parallel groups for faster
operation Raw data for key touches can be read as a report over the SPI interface Discrete Outputs: Configurable “Detect” outputs indicating individual key touch (7-key mode) Device Setup: Device configuration can be stored in EEPROM Technology: Patented spread-spectrum charge-transfer (direct mode) Key Outline Sizes: 6 mm × 6 mm or larger (panel thickness dependent); widely different sizes and
shapes possible, including solid or ring shapes Key Spacings:
7 mm center-to-center or more (panel thickness dependent) Layers Required:
One Electrode Materials:
Etched copper, silver, carbon, Indium Tin Oxide (ITO) Electrode Substrates:
PCB, FPCB, plastic films, glass Panel Materials:
Plastic, glass, composites, painted surfaces (low particle density metallic paints
possible) Panel Thickness:
Up to 10 mm glass, 5 mm plastic (electrode size dependent) Key Sensitivity:
Individually settable via simple commands over serial interface Adjacent Key Suppression® (AKS®)
Patented AKS technology to enable accurate key detection Interface:
Full-duplex SPI slave mode (1.5 MHz)...
