Product Details

Unlike most resistive touch screen controllers, the BU21029GUL 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.

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
