In a first part, this article shows the STM32MP157 line part number codification and block diagram. STM32MP157 belongs to STM32MP1 Series (refer to the list of part numbers provided below).
The second part of this article digs into technical aspects, and provides entry points to:
- 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 dowloaded into the STM32MP15 device.

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.
Arm® Cortex®-M4 coprocessor and its peripheral set are directly inherited from the STM32 MCU family .
2 Part number codification
The table below shows the STM32MP15 microprocessor different part numbers available, together with their corresponding internal peripherals, security options and packages.

3 Block diagram
Here below is the STM32MP157F block diagram offering the richest features set of the STM32MP15 microprocessor.
Notice that the diagram above is a functional view that is not fully aligned with the real design. 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
- STM32MP15 Reference Manual: device and internal peripheral user specifications
- STM32MP15 Datasheet: electrical characteristics, package and pinout descriptions
5 Internal peripherals
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).
