AT42QT1110-AU

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

Moisture Tolerance



Increased moisture tolerance based on hardware design and firmware tuning

Power:



3 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
