STMicroelectronics — STM32MP1 Series Dual-Core Microprocessors

STMicroelectronics STM32MP1 Series Dual-Core Microprocessors

Dual-core microprocessors execute real-time operations at low power

The STM32MP1 series of multi-core microprocessors from STMicroelectronics features high-performance computing and graphics capabilities combined with power-efficient real-time control and multiple integrated features.


The heterogeneous architecture implemented in the STM32MP1 processors combines Arm® Cortex®-A7 and Cortex®-M4 cores. This flexible architecture performs fast processing and real-time tasks on a single chip while maintaining high power efficiency. For example, by stopping Cortex-A7 execution and running only from the more efficient Cortex-M4, power can typically be reduced by 75%.


STM32MP1 processors support a wide range of external DDR SDRAM and Flash memories. The processors are backed by ST’s OpenSTLinux, a mainlined open-source Linux® operating system distribution. The distribution contains all the essential building blocks for running software on the application processor cores.


To support development with the high-performance STM32MP1 products, ST provides a broad ecosystem of software packages and support for cutting-edge open-source security initiatives.


The code available from ST for security mechanisms includes the Open Portable Trusted Execution Environment (OP-TEE) and the Trusted Firmware-A (TF-A) projects. This helps developers using the STM32MP1 series processors to address the key elements of information security in their applications: confidentiality, integrity, availability, and authentication.


ST has also introduced software expansion packages tailored for the STM32MP1 which help designers to deploy artificial intelligence (AI) in computer vision projects and to accelerate the development of predictive maintenance applications. These include X-LINUX-AI, an expansion package which contains AI frameworks and application examples for the Linux operating system to help designers to quickly begin implementing computer vision use cases with STM32 evaluation boards and Discovery kits.


To accelerate development of predictive maintenance applications, the X-LINUX-PREDMNT expansion package helps to implement edge gateway features between sensors and cloud services.
