SY22312CS42-J00 is 11-channel multi-spectrum light sensor. It’s suitable for applications where spectrum identification and color matching are necessary. SY22312CS42-J00 can then detect 8 channels which cover visible range from 380nm to 780nm, along with Flicker channel to detect low frequency ambient light flicker. 

SY22312CS42-J00 also integrates a near infra-red channel which can sense 800~1100nm infra-red light. The NIR channel in combination with all other visible channels can provide surrounding ambient light information and help to distinguish light source type. Flicker sensing engine can calculate whether it’s 100Hz or 120Hz via relative flag bit by internal algorithm, and can also buffer data to calculate flicker frequency by external logic algorithm. 

SY22312CS42-J00 provides a separate pin for various types of interrupt schemes which simplifies system design complexity by eliminating the need to poll sensor readings. A SMBus compatible I2C interface is also integrated for easy connection to a microcontroller or embedded controller. 

SY22312CS42-J00 design featuring high SNR performance, high data uniformity, user friendly interface, wide operating temperature range, is suitable for battery-powered equipment with the requirements of ambient light sensing and proximity sensing.
