Low Power Modes on STM32 Microcontrollers

This document, originating from Université Savoie Mont Blanc, provides an in-depth exploration of low-power modes available on STM32 microcontrollers. It details techniques for reducing power consumption, essential for embedded systems development. The guide covers specific STM32 series like STM32F446RE and STM32L073RZ, discussing their processor modes, sleep states, and standby features. It also introduces measurement tools such as the X-NUCLEO-LPM01A board and the STM32CubeMonitor-Power software for analyzing power consumption. Practical advice on debugging low-power applications is also provided, making it a valuable resource for engineers and students working with STM32 platforms.

Key topics include:

• Understanding processor modes and low-power states (Sleep, Stop, Standby).
• Methods to reduce power consumption by optimizing CPU frequency, clock sources, and peripherals.
• Practical measurement setups using STMicroelectronics hardware and software tools.
• Strategies for debugging applications operating in low-power modes.

This resource is ideal for developers seeking to enhance the energy efficiency of their embedded designs. For more information on STM32 microcontrollers, visit the STMicroelectronics website.
