11-key QTouch^®Touch Sensor IC

DATASHEET

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 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), CHANGE pin, discrete detection

outputs
