BU21029MUV Overview
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.
Key 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 voltage
- Temperature range
