AS7221 CCT Tuning Smart Lighting Manager

Network-Enabled Sensing and Integrated IoT Luminaire Management for Spectrally Tunable Systems

AS7221 is a networking-enabled IoT Smart Lighting Manager with embedded tri-stimulus color sensing for direct CIE color point mapping and control. IoT luminaire control is through a network connection, or by direct connection to 0-10V dimmers, with control outputs that include direct PWM to LED drivers and analog 0-10V to dimming ballasts. A simple text-based Smart Lighting Command Set and serial UART interface, enables easy integration to standard network clients.

Key Features

  • XYZ tri-stimulus sensor for accurate CCT/spectral control
  • Compatible with standard dimmer, occupancy controls and ballasts
  • Built-in PWM generator for precise 1% dimming
  • 2.3 x 2.5mm WLCSP or 4.4 x 4.5mm LGA packages

Key Benefits

  • Networked CCT/spectral tuning management
  • Direct 0-10V inputs/outputs
  • Direct PWM interfaces
  • Choice of compact 20-pin packages
