STM32MP15 microprocessors are based on the Arm® Cortex®-A7 dual core. They support Trustzone mode for secure operations, a Vivante GPU and an Arm® Cortex®-M4 coprocessor.
This article starts with information on STM32MP15x lines 
part number codification and block diagram. STM32MP15x belongs to STM32MP1 series (refer to the list of part numbers provided below).
Then technical aspects are introduced, providing information on:
- STM32MP15 documentation
- articles dedicated to Internal peripherals that make the transition towards the software frameworks required to control these peripherals
- the list of boards supporting STM32MP15 devices
- the supported software distributions, that can be downloaded into the STM32MP15 device.
1. Introduction[edit | edit source]
STM32MP15x microprocessors are targeting industry 4.0, factory automation, smart metering, smart homes and electric vehicle charging infrastructure applications.
They are based on the flexible architecture of a Dual Arm® Cortex®-A7 core running up to 800 MHz and Cortex®-M4 at 209 MHz combined with a dedicated 3D graphics processing unit (GPU) and MIPI-DSI display interface.
2. Part number codification[edit | edit source]
The figure below shows the differences between the three STM32MP15x lines, with their security and frequency options. Each line can be delivered in one of four packages represented on the right side: refer to the technical documentation to get details on the available features per package.
The tables below explains how the part numbers are encoded for all the above combinations.

2.4. Junction temperature[edit | edit source]
3. Block diagram[edit | edit source]
Here below is the STM32MP157F block diagram offering the richest features set of the STM32MP15 microprocessor.
The above figure shows a functional view of the design that does not aim to be aligned with the real design: it shows the available features and not how they are implemented into the microprocessor.
For instance, SPDIF RX and SPDIF TX functions are grouped in a single box, whereas, SPDIF RX is implemented in one dedicated peripheral, and SPDIF TX is supported by SAI.
4. Technical documentation[edit | edit source]
- STM32MP15 Reference Manual: device and internal peripheral user specifications
- STM32MP15 Datasheet: electrical characteristics, package and pinout descriptions
The whole documentation set, related to STM32MP15x lines , is available also on st.com [3]
5. Internal peripherals[edit | edit source]
STM32MP15 peripherals overview article gives a description of all the internal peripherals available on STM32MP15 devices, with direct links to the articles where you can find:
- an overview of each peripheral
- the list of instances available for each peripheral type,
- information on the way each instance can be shared between Arm® Cortex®-A7 and Cortex®-M4 cores,
- direct links to the software frameworks used to control the peripheral from different Arm® cores and security modes such as Cortex®-A7 non secure, Cortex®-A7 secure or Cortex®-M4 (non secure).
