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 ■ Single 1.
65V to 3.
60V supply ■ Power on reset ■ Auto power down control ■ Built-in clock oscillator circuit
●Key Specifications ■ Power supply
