Datasheet 4-wire Resistive Touch Screen Controller BU21029MUV ●General Description Unlike most resistive touch screen controllers, the BU21029MUV 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. ●Features ■ Single and dual touch detection for standard 4-wire resistive touch screens ■ I2C-like interface for interfacing with the host processor ■ 12-bit resolution ■ Singl.
