BU21028FV-M Datasheet 4-wire Resistive Touch Screen Controller

Manufacturer: ROHM

General Description

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.
