Features
Sensor Keys:
– Up to 11 QTouch channels
Data Acquistion:
– Measurement of keys triggered either by a signal applied to the SYNC pin or at
regular intervals timed by the AT42QT1111's 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 x 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 Good
Power:
– 1.8V ~ 5.5V
Package:
– 32-pin 5 x 5 mm MLF RoHS compliant
– 32-pin 7 x 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, etc
QTouch 11-key
