The AS7221, introduced as the industry’s first integrated white-tunable smart lighting manager, allows lighting manufacturers to quickly integrate high-precision CCT, or “Kelvin-tuning”, capabilities into their Internet of Things (IoT) smart lighting offerings. Its architecture includes an I2C extension interface, allowing it to deliver Internet of Awareness IoT sensor hub platform capabilities for sensing functions such as air quality, temperature, occupancy, and presence. The device integrates an industry-first embedded tri-stimulus CIE XYZ color sensor and is compatible with standard 0-10V inputs and enabled for IoT connectivity and network control through standard clients such as Bluetooth Smart, ZigBee or WiFi, through a complete Smart Lighting Command Set. LED control for spectral tuning is implemented via direct PWM channel outputs, resulting in a high-precision solution that slashes development and integration time when compared with more bulky discrete component approaches. Pricing for the AS7221 is set at $3.13 each/10,000. For more details, go to or email
