Detalhes do produto
BU21021GUL is a resistive touch screen controller,which is capable of detecting 2 points touch with a legacy 4-wire resistive touch screen. BU21021GUL is capable of detecting X/Y coordinates, touch pressure in1 point detection mode, and a pair of X/Y coordinates in2 point detection mode. It is also capable of recognizing multiple finger gestures from coordinate data variation and notifying to host with gesture detection flags respectively. BU21021GUL employs embedded CPU for noise filtering, coordinate calculation, gesture detection and other signal processing required on a chip.
