Introducing SMED

The heart of the STLUX family is the SMED (state machine event driven) technology which

allows the device to pilot six independently configurable PWM clocks with a maximum

resolution of 1.3 ns. A SMED is a powerful autonomous state machine, which is

programmed to react to both external and internal events and may evolve without any

software intervention. The SMED reaction time can be as low as 10.4 ns, giving the STLUX

the ability of operating in time critical applications. The SMED offers superior performance

when compared to traditional, timer based, PWM generators.

Each SMED is configured via the STLUX internal microcontroller. The integrated controller

extends the STLUX reliability and guarantees more than 15 years of both operating lifetime

and memory data retention for program and data memory after cycling.

A set of dedicated peripherals complete the STLUX:



4 analog comparators with configurable references and 50 ns max. propagation delay.

It is ideal to implement zero current detection algorithms or detect current peaks.



10-bit ADC with configurable op amp and 8-channel sequencer.



DALI: hardware interface that provides full IEC 60929 and IEC 62386 slave interface.



96 MHz PLL for high output signal resolution.
