Universal Lighting Controller

ST Microelectronics (Geneva, Switzerland) has introduced the STLUX385 (Masterlux™ platform), the world’s first programmable digital controller specifically optimized for lighting and power-supply applications. The STLUX385 integrates six specially-designed peripherals called SMED (State Machine, Event- Driven) circuits that interact with each other and with external signals via a programmable switching matrix to control the power delivered to the lighting elements. In addition to the specific application signals, the SMEDs can process external commands to turn the lights on/off or set the dimming level, diagnostic signals such as open- or short-circuit detected, or inputs from sensors in applications where the lighting is designed to adapt to ambient conditions.
