It is a digital light intensity sensor IC for a two-wire serial bus interface.
The brightness of the LCD and keyboard backlights can be adjusted using the light intensity data collected by the module.
The module resolution can detect a wide range of light intensity changes.
Spectral sensitivity feature：typical value of wave length about sensitivity: 560nm.
Weak dependency of light source: optional incandescent lamp, fluorescent lamp, halogen lamp, white light LED.
