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 AT42QT1110'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

QTouch^™11-key

Sensor IC

• 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:

AT42QT1111-MU

AT42QT1111-AU

– 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
