Product Details

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.

Legacy 4-wire resistive touch screen is applicable
1 point / 2 points touch detection
On chip coordinate generation
Multiple gesture detections
3V single power supply
Higher coordinate resolution with 12-bit SAR A/D converter
On chip clock generator
Selectable HOST I/F(IFSEL pin) 4-wire SPI / 2-wire serial bus
