STM32MP25 peripherals overview

Applicable for

This article lists all internal peripherals embedded in STM32MP25x lines and shows the assignment possibilities to the execution contexts for each one of them.
From this article, you can also access to individual peripheral articles with information related to the overview and configuration aspects.

1. Internal peripherals overview[edit source]

The figure below shows all peripherals embedded in STM32MP25x lines , grouped per functional domains that are reused in many places of this wiki to structure the articles.
Several execution contexts exist on STM32MP25x lines ^[1], corresponding to the different Arm cores and associated security modes:

Arm dual core Cortex-A35 secure (Trustzone), running ROM code and TF-A BL2 at boot time, and running OP-TEE and/or TF-A BL31 at runtime
Arm dual core Cortex-A35 non secure , running U-Boot at boot time, and running Linux at runtime
Arm Cortex-M33 secure (Trustzone), running TF-M
Arm Cortex-M33 non-secure , running STM32Cube

The legend below shows how assigned and shared peripherals are identified in the assignment diagram that follows:

When a peripheral box owns execution context color, that means the assignment of this peripheral is fixed by hardware to the execution context.
When a peripheral box owns a mix of two execution colors that means this peripheral is shared by hardware between the two execution contexts.
When a peripheral box has dark gray color, that means this peripheral is protected by RIF and could be assigned to any execution context.
When a peripheral box has light gray color, that means this peripheral is a RIF-aware peripheral. This peripheral owns several features which can be assigned independently to any execution context.

Internal peripheral assignment tables list assignment capabilities for each peripheral.

Both the diagram below and the following summary tables (in Internal peripherals runtime assignment and Internal peripherals boot time assignment chapters below) are clickable in order to jump to each peripheral overview articles and get more detailed information (like software frameworks used to control them). They list STMicroelectronics recommendations. The STM32MP25 reference manual ^[2] may expose more possibilities than what is shown here.

STM32MP25 internal peripherals

Check boxes illustrate the possible peripheral allocations supported by STM32 MPU Embedded Software:

☐ means that the peripheral can be assigned to the given runtime context.
☑ means that the peripheral is assigned by default to the given runtime context and that the peripheral is mandatory for the STM32 MPU Embedded Software distribution.
⬚ means that the peripheral can be assigned to the given runtime context, but this configuration is not supported in STM32 MPU Embedded Software distribution.
✓ is used for system peripherals that cannot be unchecked because they are hardware connected in the device.

The present chapter describes STMicroelectronics recommendations or choice of implementation. Additional possibilities might be described in STM32MP25 reference manuals.
