Product Details

Unlike most resistive touch screen controllers, the BU21028FV-M 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.

AEC-Q100
standard 4-wire resistive touch screens
Single and dual touch detection
I²C-like interface (for the host processor I/F)
12-bit resolution
Single 2.7V to 3.6V power supply
Auto power down/on control
Built-in clock oscillator circuit
