Renesas is a member of the Digital Illumination Interface Alliance (DiiA). We have offered MCU products, evaluation boards, and protocol stacks supporting the DALI interface for over a decade, and a large number of customers in many countries have adopted these products. DALI protocol stack components from Renesas have been tested Official DALI tester *1, who must all be members of the DiiA, so customers can use them with confidence. A number of library versions have also been developed by partner vendors working closely with Renesas. Moving forward, Renesas is committed to fostering the widespread adoption of DALI by supporting the development work of customers in collaboration with our partner vendors.



DALI-2 TOTAL Solution is useful solution to support both “Control Device” (master application like a router), and “Control Gear” (slave application like a lighting fixture). Users can save stack and application development resource from half to 1 year for by making use this solution.

DALI-2 Total Solution

Control Device: Application Controller

  • FreeRTOS that can support cloud service condition and DALI Application Controller library ( support IEC62386-103 )
  • Able to control dimmer by 3 type, Web(AWS), PC(GUI), Switch (Local)
  • ID certification, support to OTA
  • DALI Driver that can support proprietary frame for future extended function

Control Gear

  • Proven DALI Control Gear library (support IEC62836-102 )
  • Contribute CPU workload and code scale reduction, and total board cost reduction by DALI communication and peripheral function in RL78/I1A that can support digital power control.
  • Easy evaluation by auto-generation tool
