BU21049GUL Description
Unlike most resistive touch screen controllers, the BU21049GUL 4-wire resistive touch-screen controller generate data to enable dual touch detection. The Host processor can use data to detect single point coordinates and dual coordinates.
BU21049GUL Key Features
- Enables single touch and dual touch using standard 4-wire resistive touch screen
- I2C like interface for interfacing to the host processor
- 12-bit Resolution
- Single 1.65V to 3.60V Supply
- Power on reset
- Auto power down control
- Built-in clock oscillation circuit
