STM32
The degree of digitalization and intelligence of industrial applications is an important criterion for measuring new quality productivity. STM32MP2, the latest generation of 64-bit microprocessors from STM32, empowers high-performance and highly connected Industry 4.0 applications with advanced computing power, rich interfaces and high security.
Four key features of STM32MP2 enable Industry 4.0 applications
The first product in the STM32MP2 series, the STM32MP25, is now in mass production, with a junction temperature range of -40 to 125 degrees Celsius, supporting 100% operation time for 10 years, and has a 10-year rolling supply guarantee like other STM32 products.

The STM32MP2 has a heterogeneous architecture and excellent performance, strong security performance, advanced edge AI capabilities and multimedia functions, and has rich peripheral interfaces and on-chip functions, which can reduce the burden on the CPU in applications.
The STM32MP25 has a large-core and large-core heterogeneous architecture with excellent performance:
a dual-core Cortex-A35 with a main frequency of 1.5GHz and a Cortex-M33 with a main frequency of 400MHz, both of which can be started separately. The large Cortex-A35 core usually runs applications based on Linux or Android, and can meet users' high-end and complex business needs in combination with 3D GPU, video codec, high-speed peripheral interfaces, etc.; the Cortex-M33 core not only has the ability to directly access on-chip SRAM resources, but also can efficiently access on-board DDR storage. When running key applications such as hard real-time based on bare metal or real-time operating systems (RTOS), it can enjoy high data throughput and sufficient memory resources, thereby ensuring efficient operation and real-time response of the system. The heterogeneous dual-core can achieve efficient dual-core communication based on on-chip shared memory, and can flexibly allocate on-chip resources.
Stronger security features for Industry 4.0 applications:
The STM32MP25 has passed SESIP Level 3 and PSA Level 1 target certification, and has built-in powerful security encryption hardware to protect memory and peripherals to prevent unauthorized access and control;
it has a security encryption accelerator to enhance robustness against physical attacks;
it supports runtime code isolation protection and device authenticity verification during the product life cycle.
Advanced edge AI and rich multimedia functions empower more industrial scenarios:
STM32MP25 has a built-in NPU edge AI accelerator with a computing power of up to 1.35 TOPS, supports MIPI CSI interface with ISP, and can realize a variety of AI applications such as machine vision; STM32MP25 also has a built-in 3D GPU with a main frequency of 900MHz; developers can flexibly choose to run AI applications on CPU, GPU, and NPU.
The 3D GPU supports up to 1080p resolution and is equipped with a MIPI CSI-2 camera interface with an ISP processor. The STM32MP25 also has built-in full HD video codec and a rich display interface, supporting RGB, LVDS and DSI output.
The STM32MP25 has a rich set of peripheral interfaces and on-chip functions that can offload the CPU in applications.

Figure: Industrial HMI Gateway Block Diagram
Take the industrial HMI gateway as an example:
-
The STM32MP25 has a built-in H.264 full HD video processor, 3D GPU graphics processor, ISP image signal processor and display controller, and assists the Cortex-A35 CPU to achieve a high-performance HMI graphical interaction interface;
-
Cortex-M33 MCU handles industrial hard real-time applications;
-
The multi-channel Gigabit Ethernet with built-in TSN switch function of STM32MP25 can realize Ethernet ring topology;
-
The PCIe high-speed interface allows users to connect FPGA and other peripherals to achieve high-speed communication;
-
Various fieldbus communications can be achieved through CANFD, UART/USART and other bus interfaces;
-
The Cortex-A35 and Cortex-M33 have their own independent power domains and can be started separately, ensuring that in industrial scenarios, when Linux or Android-based applications on the A35 core need to be restarted for some reason, the real-time applications on the M33 will not be interrupted;
-
The Cortex-A35 has excellent energy efficiency. When combined with the matching power management chip STPMIC25, it can simplify the design and optimize power consumption. When designing products, users do not need to configure additional heat dissipation devices for MP25, which not only saves material costs and PCB space, but also ensures product reliability, stability and a longer life cycle.
STM32MP2 product lineup is strong
STM32MP25 has four product lines, STM32MP257, STM32MP255, STM32MP253 and STM32MP251, which are in mass production according to different peripherals. In addition, STM32MP23 and STM32MP21 will also be released this year and next year.
