The AS7225 is equipped with the product family’s industry-first embedded tri-stimulus CIE XYZ color sensor to enable precise color sensing with direct mapping to the International Commission on Illumination (CIE) 1931 color space which is recognized as the standard coordinate definition for human color perception. CCT and daylighting tuning directives are communicated to the host microprocessor via an industry standard I2C interface, allowing IoT smart lighting manufacturers to avoid costly calibration and tuning algorithm development and reduce time to deployment.

FEATURES
• XYZ tri-stimulus chromatic sensing
• Simple register-based control commands
• I2C interface
• Calibrated nano-optic silicon interference filters
• Readable registers for CIE 1931 and 1975 color-point coordinates, CCT, duv and lux
• 4.5 x 4.7 x 2.5mm 20-pin LGA package
• 0°C to +85°C operating temperature
• 1k MSRP: $2.40 US
