Ultra-low power MCUs. What makes STM32L5 MCUs special - Webinar Replay

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.

Content:
STM32L5 overview and description
Demos: CoreMark, Consumption measurement with CoreMark, Low-power applications

This webinar is from our premium 2020 premium archives. We are making it available to a wider audience as we believe it still provides relevant and useful technical information to those of you interested by the subject matter.

We’ve optimized the content as far as possible by condensing the material and adjusted the audio.
