BU21049GUL
BU21049GUL is 4-wire Resistive Touch Screen Controller manufactured by ROHM.
Description
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.
