STMicroelectronics has released the STLUX development environment that includes demonstration boards, a graphical configurator, software libraries and compiler. According to the company, it provides everything needed to start designing high-performance LED lighting with STLUX385A, the first in the company's family of lighting controllers boasting ST's breakthrough digital control technique.

The SMED is an advanced hardware-configurable state machine where state advancement is automatically triggered by internal or external events, ensuring faster response than a conventional interrupt-driven microprocessor, ST noted. In addition, the STLUX385A supports smart grid connectivity and DALI1 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 available for sampling from ST.

STLUX development platform

The STLUX385A includes six SMEDs with 10ns reaction time, four analog comparators with internally-generated and external references, an ADC with an 8-channel sequencer, native DALI, built-in memory including 32KB program Flash, serial and I2C communication channels and an integrated low-power STM8 MCU. The STLUX development environment also provides a highly optimised compiler for the MCU, together with the related in-circuit debugger/programmer.
