Introduction

All STM32H5 series feature a variety of power-saving mechanisms that can help to reduce significantly power consumption.

Thus, it enables an optimal balance between performance processing and power efficiency.

This document dealing with the STM32H5 series describes the system architecture and configurations. It also provides

guidelines related to the different power modes and the reduction of power consumption. The document outlines different ways

of:

• Decreasing power consumption

• Optimizing battery life

The smart power management includes the cache configuration, the DMA access, and many other features.
