Engineers are increasingly tasked with deploying edge artificial intelligence (AI) capabilities that balance complex data processing, stringent security requirements, and low power consumption. Advanced Industrial Internet of Things (IIoT) devices in factories, transportation, and energy systems must analyze data in real time, often in rugged environments where latency and security are vital. Processing vast amounts of data quickly and securely at the edge, rather than relying on cloud infrastructure, minimizes latency and reduces vulnerability to cyber threats. However, implementing these solutions with limited power budgets and maintaining hardware that’s robust enough for industrial settings while meeting Industry 5.0 requirements adds another layer of difficulty. Engineering teams need solutions that offer both performance and reliability without extensive power demands or security trade-offs.
This week’s New Tech Tuesday focuses on how the second-generation, industrial-grade 64-bit STM32MP25x microprocessors from STMicroelectronics meet these needs.
The STM32MP25x microprocessor series has a powerful architecture and industrial-grade features that address the array of challenges engineers face when adopting edge AI in IIoT. Built on a 64-bit framework, this second-generation microprocessor series is purpose-designed to support advanced edge computing in Industry 5.0 applications. With the Security Evaluation Standard for IoT Platforms (SESIP) Level 3 certification for system integrity, dedicated edge AI accelerators, and a secure development ecosystem, the STM32MP25x series (Figure 1) is on track to redefine IIoT security, responsiveness, and intelligence.

Edge AI requires real-time data processing close to where data is generated, and the STM32MP25x series includes a powerful neural processing unit (NPU) to meet this demand. This NPU offers up to 1.35 trillion operations per second (TOPS), accelerating machine learning tasks and allowing developers flexibility in deploying AI workloads on the central processing unit (CPU), graphics processing unit (GPU), or NPU as needed. By enhancing data processing capabilities, the STM32MP25x supports more responsive and adaptive IIoT systems, particularly in applications where latency and real-time decision-making are critical, such as predictive maintenance and quality control systems.
Beyond AI acceleration, the STM32MP25x series features multimedia capabilities ideal for edge devices handling video and graphical data. This includes vision processing unit (VPU)-based video encoding/decoding and a GPU capable of delivering full HD graphics, enabling smooth visual interfaces. Such multimedia support is essential for applications like industrial inspection, where high-resolution imaging and video processing are central. This functionality makes the STM32MP25 suitable for various smart IIoT applications, from remote monitoring to augmented reality (AR) for repair and maintenance.
The STM32MP25x series is equipped with three gigabit Ethernet ports, PCIe Gen2, and USB 3.0 to simplify data communication across devices and networks in industrial setups. Its inclusion of time-sensitive networking (TSN) support and multiple flexible data-rate controller area network (FDCAN) peripherals allow for precise and reliable communication, ensuring data integrity across connected devices. These connectivity features are critical for industrial applications needing high data transfer speeds, like automated manufacturing lines or real-time monitoring systems.
The STMicroelectronics STM32MP25x microprocessor series is a game-changer in edge AI and IIoT technology, integrating powerful processing, advanced multimedia capabilities, extensive connectivity, and hardened security. With features like the 1.35 TOPS NPU for AI acceleration, SESIP Level 3 certification for secure operations, and high-speed network interfaces, these devices enable the creation of intelligent, responsive, and resilient industrial applications. Engineers seeking robust solutions for Industry 5.0 and beyond will find ST’s STM32MP25x microprocessors an invaluable asset, bringing both enhanced performance and security to the forefront of their IIoT systems.
