AT42QT2100

In Production

The QT2100 is the functional replacement of the QT1106. It is a capacitive touch controller with 10 configurable QTouch?? channels, up to seven buttons and either 1-slider or 1-wheel. The QTouch, self capacitance sensing algorithm is the more simplistic algorithm that measures the capacitance between one sensing electrode and another object (usually a finger). The button sensors can be constructed in a variety of shapes and sizes. The device includes all signal processing functions necessary to provide stable sensing under a wide variety of changing conditions and frequencies.

    • Demo & Eval Boards
    • QT1 Xplained Pro extension kit ( ATQT1-XPRO )

      QT1

      QT1 Xplained Pro kit is an extension kit that enables evaluation of self- and mutual capacitance mode using the Peripheral Touch Controller(PTC). The kit shows how easy it is to design a capacitive touch board solution using the PTC without the need for any external components. The kit includes two boards, one using self-capacitance and one using mutual capacitance.

    • SAMC20 QTR Demo ( ATSAMC20-QTRDEMO )

      SAMC20

      The SAM C20 QTouch Robustness Evaluation kit demonstrates the high capacitive touch performance of the Peripheral Touch Controller (PTC) while achieving best-in-class conducted immunity and moisture tolerance required in home appliance and industrial applications.

      The demo is based on the QTouch Library.

      Key features:
