Stm32 energy storage power supply

What is the main supply of STM32?

The main supply of STM32 is called VDD. On the simplest products and/or the smallest packages, this is used to supply the entire device. Slightly more advanced products have other input power supplies dedicated to specific features like analog peripherals, GPIO, USB, SPI, LCD. Some STM32 are internally divided into different power domains.

What is stm32h5 smart power management?

The smart power management includes the cache configuration, the DMA access, and many other features. For further information contact your local STMicroelectronics sales office. This document applies to the STM32H5 Arm®-based microcontrollers. Arm is a registered trademark of Arm Limited (or its subsidiaries) in the US and/or elsewhere.

How to reduce current consumption on STM32 peripherals?

Lowering the CPU or peripheral clock frequency helps to reduce the current consumption. Important note: A current spike is drawn when increasing the frequency, a current spike that must be handled by the power supply. 3.3.3. Peripherals On STM32 peripherals are dynamically configurable, they can be deactivated when not used.

How does a STM32 work?

Some STM32 have a range of operating voltages, this able to choose the voltage level to reduce consumption. The core voltage V CORE selected by VOSx and peripherals such as V DDIO or V DDX voltage can be modulated depending on the product. Keep in mind that lowering the voltage lowers the maximum operating frequency.

Why are STM32 microcontrollers made of different power domains?

STM32 microcontrollers are composed of different power domains. This has different purposes: To have different operating voltage. To have different power sources. To shut down some parts to reduce power consumption. To isolate from perturbations. The main supply of STM32 is called VDD.

What is STM32 microcontroller?

Cannot retrieve latest commit at this time. The STM32 platform is a family of microcontrollers based on the Arm Cortex M processor, offering among many powerful features, plenty of 12-bit analog inputs and high speed sampling, making them particularly suitable for energy monitoring applications.
