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)
