Added Value of Using AS7221

Applications

Autonomous, networked solid-state lighting manager for

variable CCT and daylight harvesting:

• Integrated smart lighting control of variable CCT white

lighting solutions

• Luminaires intended to meet California Title 24

daylighting requirements

• Commercial, retail, and residential white/color changing

LED lighting systems

• Networked lighting systems with IoT sensor expandability

Benefits

Features

• Accurate control of variable CCT and spectrally

tunable lighting

• Calibrated XYZ tri-stimulus color sensing for direct

translation to CIE 1931/1976 standard observer color

maps

• Automatic spectral and lumen maintenance

over temperature and time

• Autonomous color point and lumen output

adjustment resulting in automatic spectral and

lumen maintenance

• Direct serial interface for connection to

standard networks

• Simple UART interface for connection to network

hardware clients for protocols such as Bluetooth,

ZigBee and WiFi

• Simple lamp or luminaire configuration and

commissioning using defined command set

• Smart Lighting Command Set (SLCS) uses simple

text-based commands to control and configure a

wide variety of functions

• Compatible with standard dimmer controls and

occupancy sensors

• Directly interfaces to 0-10V dimmer controls and

standard occupancy sensors

• Directly interfaces to LED driver via PWM

• Built-in PWM generator to dim LED lamps and

luminaires

• 12-bit resolution for precise dimming down to 1%

• Directly interfaces to ballast via 0-10V

• 0-10V analog output for control of conventional

dimming ballasts in a current steering design

• Small package, wide operating range with

critical optics built-in

• 20-pin LGA package 4.5mm x 4.7mm x 2.5mm with

integrated aperture

• -40°C to 85°C
