ST Launches STM32MP1: Dual‑Core Arm Cortex MP1 with OpenSTLinux and Low‑Power Performance

STMicroelectronics leverages its Arm Cortex expertise to extend its award‑winning STM32 MCU family into the realm of high‑performance, power‑efficient, open‑source software‑centric applications. The new STM32MP1 multicore microprocessor series combines compute and graphics acceleration, real‑time control, and dense feature integration, enabling advanced Industrial, Consumer, Smart‑Home, and Health & Wellness solutions.

Built on the proven STM32 ecosystem—including development tools, middleware, and ST’s extensive partner network—the STM32MP1 delivers a heterogeneous architecture that marries an Arm Cortex‑A core for Linux and a Cortex‑M core for deterministic control. Coupled with the open‑source OpenSTLinux distribution, which has received endorsement from the Linux Foundation, Yocto Project, and Linaro, the platform addresses demanding real‑time, power‑constrained requirements while maintaining a robust supply chain backed by ST’s 10‑year longevity commitment.

Key technical highlights include:

• Dual‑core design: Arm Cortex‑A7 for high‑level processing and Cortex‑M4 for real‑time tasks. Power‑management allows the A core to be throttled or disabled, reducing consumption to roughly 25% of full‑active mode, with standby modes that cut power 2.5 k times while keeping Linux resumable in 1‑3 s.
• Integrated 3D GPU for rich HMI displays.
• Flexible memory interface supporting DDR SDRAM and external Flash.
• Comprehensive peripheral set that can be dynamically allocated to either core, enabling tight coupling between application and real‑time functions.
• Multiple BGA packages designed for low PCB cost and minimal board footprint.

ST accelerates time‑to‑market through its enhanced STM32Cube toolchain, upgraded from the familiar STM32Cube suite for Cortex‑M microcontrollers, and tailored for Cortex‑A‑core MPUs. Combined with OpenSTLinux, developers have a full stack—from bootloader to kernel to application framework—ready for rapid prototyping and production deployment.

With the STM32MP1, ST demonstrates its commitment to empowering developers with a reliable, high‑performance, and fully open‑source platform that meets the most stringent industrial and professional demands.
