Resistive Type Touch Screen Control IC - BU21029GUL

Unlike most resistive touch screen controllers, the BU21029GUL 4-wire resistive touch-screen controller can generate data that enables dual touch detection. The Host processor can use this data to detect single and dual point coordinates.

* This product is a STANDARD grade product and not recommend for on-vehicle devices.
