DALI Digital Lighting Control

The DALI digital lighting control is based on Digital Addressable Lighting Interface (DALI) technology for DiiA specified in IEC 62386. The DALI system is widely used in building automation and public transportation. Nuvoton supports software of both control device and control gear, for the reference design, Nuvoton features NDA102, and NDA103 microcontrollers. Moreover, the hardware reference design built-in RGB LED driver, Turntable white, Power component, as well as the DALI bus interface.
