BU21028FV-M Overview
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.
Key Features
- AEC-Q100(Note
- 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 (Note1: Grade 3)
