STMicroelectronics introduces the first automotive microcontroller with AI acceleration for edge intelligence

STMicroelectronics announced the Stellar P3E, the first automotive microcontroller (MCU) with built-in AI acceleration for automotive edge intelligence. Designed for future software-defined vehicles, the Stellar P3E simplifies multi-function integration for X-in-1 Electronic Control Units (ECUs) that reduce system cost, weight, and complexity.

A defining feature of the Stellar P3E is its integrated ST Neural-ART Accelerator™ for real-time AI efficiency - making it the first MCU with an embedded neural network accelerator for the automotive industry. Powered by this dedicated neural processing unit (NPU) with an advanced data-flow architecture for AI workloads, and combined with its rich sensing capabilities, the P3E enables smart sensing that opens the door to new applications such as virtual sensors.

The P3E delivers inference processing at microsecond speeds, achieving up to 30x greater efficiency compared to traditional MCU core processors. This enables always-on, low-power artificial intelligence (AI) that can support real-time functions, including predictive maintenance and smart sensing, delivering significant benefits across a wide range of applications. For example, these capabilities can enhance charging speed and efficiency in electric vehicles and enable rapid deployment of new features, whether in the factory or in the field. Original equipment manufacturers (OEMs) can introduce new functions and more intuitive behaviors through different AI models, reducing the need for additional sensors, modules, wiring, and integration effort (more info).
