Ultra-low power MCUs - what makes STM32L5 MCUs special

Join us for 1-hour webinar on STM32L5 MCUs: the right architecture to meet your power consumption targets

This webinar was broadcasted Tuesday, June 2nd 2020

Ultra-low power applications typically go through three different phases, which are repeated several times: the inactive phase, the inactive-to-active transition phase and the active phase. 

In order to reduce the amount of energy needed during each phase and save battery lifetime, microcontrollers need to offer:

- efficient computation power and smart peripherals to reduce current consumption  and the time spent in the active phase

- a fast wake-up time, to spend minimal time in the inactive-to-active transition phase

- multiple low-power modes to be able to select the most appropriate one for given use cases and reduce current consumption in the inactive phase.

During this one-hour webinar, our experts will present the STM32L5 architecture and technical features that directly address the requirements of ultra-low power applications and show you several live demos.


  • STM32L5 overview and ultra-low power features
  • STM32L5 offers computation performance and efficiency
  • Demo: CoreMark
  • Demo: Consumption measurement with CoreMark
  • STM32L5 low power modes and their typical selection
  • Demo: Low-power applications
  • Conclusion

There will be a live Q&A session at the end of the webinar where ST’s experienced engineers will be available to answer your questions.
