Features
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 AT42QT1111 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 (750 kHz), CHANGE pin, discrete detection outputs
Moisture Tolerance
Increased moisture tolerance based on hardware design and firmware tuning
Power:
1.8 V – 5.5 V
Package:
32-pin 5 × 5 mm QFN RoHS compliant
32-pin 7 × 7 mm TQFP RoHS compliant
Signal Processing:
Self-calibration, auto drift compensation, noise filtering, AKS technology
Applications:
Consumer and industrial applications, such as TV, media player
