STMicroelectronics has revealed a development environment for designing LED lighting with its lighting controller, STLUX385A. The platform comprises demonstration boards, a graphical configurator, software libraries, and compiler.

The company has developed plug-and-play demonstration board featuring all controller functionalities and a user-friendly ecosystem for programming PWM waveforms using the six on-chip SMED (State Machines Event Driven) digital controllers.

The SMED is an advanced hardware-configurable state machine where state advancement is automatically triggered by internal or external events thereby ensuring faster response than a conventional interrupt-driven microprocessor. In addition, the controller supports smart-grid connectivity and digitally addressable lighting interface communication for remote control, enabling use in energy-efficient lighting throughout smart cities.

Using the STLUX development environment, designers can control the STLUX385A via a serial line and a console. The graphical SMED configurator simplifies design of innovative topologies targeting maximum efficiency at full load with minimum energy consumption in idle conditions, high-quality dimming with high current-control precision. Ready-to-use application examples are also provided.

The demonstration boards are currently available for sampling from ST. For further information and links to all components of STLUX ecosystem, please visit

The development board is expected to help designers familiarise themselves with the STLUX385A device and the innovative SMED (state machine, event driven) functionality.
