4-wire Resistive

Touch Screen Controller

BU21049GUL

●General Description

●Key Specifications

Unlike most resistive touch screen controllers, the

BU21049GUL 4-wire resistive touch-screen controller

generate data to enable dual touch detection.

The Host processor can use data to detect single point

coordinates and dual coordinates.
