Resistive Type Touch Screen Controller ICs BU21023GUL BU21023MUV General Description Unlike most resistive touch screen controllers, the BU21023 4-wire resistive touch screen controller enables dual-touch detection and gesture recognition. These intelligent controllers expose a set of registers to a HOST processor and are configured through software. The controllers can detect single point coordinates, dual coordinates, pinch, spread, rotate left and rotate right gestures, enabling pan and zoom operations in applications that previously had to rely exclusively on capacitive touch technology. Resistive touch does not require custom screen development which reduces development...
