Description
General part information
AT42QT2640 Series
The Microchip's AT42QT2640 is a capacitive touch controller with configurable 64-QTouch buttons. The Microchip QMatrix sensing algorithm (mutual capacitance) enables the user to achieve more buttons than there are pins because of this matrix layout. The device includes all signal processing functions necessary to provide stable sensing under a wide variety of changing conditions and frequencies.
UL and IEC certified according to IEC/EN 60730 (Ed. 4.0) / IEC/EN 60335 (Ed. 5.0) for Appliance safety class B.
