The newest technology of microcontroller models, or MCUs, guarantees to allow builders to push extra synthetic intelligence to edge units equivalent to robots. STMicroelectronics International NV this month introduced a brand new MCU sequence that it claimed is its strongest to this point and integrates accelerated machine studying capabilities.
“We are on the verge of a significant transformation at the tiny edge. This transformation involves the increasing augmentation or replacement of our customers’ workloads by AI models,” said Remi El-Ouazzane, president of the Microcontrollers, Digital ICs and RF Products Group (MDRF) at STMicroelectronics. “Currently, these models are used for tasks such as segmentation, classification, and recognition. In the future, they will be applied to new applications yet to be developed.”
Geneva, Switzerland-based STMicroelectronics mentioned it has extra then 50,000 staffers making semiconductor applied sciences. The built-in system producer works with over 200,000 clients and 1000’s of companions to design and construct merchandise, techniques, and ecosystems that handle their challenges.

STM32N6 consists of new options
STMicroelectronics mentioned its STM32N6 sequence is the primary MCU to embed its proprietary neural processing unit (NPU), the Neural-ART accelerator, which it designed for power-efficient edge AI purposes. The firm asserted that the MCU can ship 600 instances extra machine-learning efficiency than a high-end STM32 MCU at the moment.
The STM32N6 options an 800 MHz Arm Cortex-M55 core and boasts 4.2 MB of RAM for data-intensive workloads. The Neural-ART Accelerator runs at 1 GHz and supplies as much as 600 GOPS (Giga operations per second), enabling real-time neural community inference for laptop imaginative and prescient and audio purposes, mentioned STMicroelectronics.
For the primary time on an MCU, the STM32N6 incorporates a picture sign processor (ISP) that gives direct sign processing, enabling using easy and inexpensive picture sensors, the corporate mentioned. This ISP may be configured with the free STM32-ISP-IQTune software program for customizable parameters equivalent to publicity time, distinction, or shade stability.
“[The STM32N6] will utilize a new release of our unique AI software ecosystem package,” mentioned El-Ouazzane. “This marks the beginning of a long journey of AI hardware-accelerated STM32, which will enable innovations in applications and products in ways not possible with any other embedded processing solution.”
STMicroelectronics added {that a} devoted laptop imaginative and prescient pipeline with a MIPI CSI-2 interface ensures compatibility with a variety of cameras. The STM32N6 additionally options an H264 {hardware} encoder and the NeoChrom Accelerator for graphics, making it appropriate for feature-rich merchandise.
Available in six totally different packages starting from 169 to 264 pins and from 0.4 to 0.8 mm pitch, the MCU helps as much as 125°C ambient temperature, making it appropriate for harsh environments.
“It is a common misconception that AI is purely a big data center, power-hungry application,” noticed Tom Hackenberg, principal analyst within the Memory and Computing Group at Yole Group.
“This is no longer true,” he mentioned. “Today’s IoT [Internet of Things] edge applications are hungry for the kind of analytics that AI can provide. The STM32N6 is a great example of the new trend melding energy-efficient microcontroller workloads with the power of AI analytics to provide computer vision and mass sensor-driven performance capable of great savings in the total cost of ownership in modern equipment.”
STMicroelectronics MCU helps AI, app dev
STMicroelectronics mentioned its Edge AI Suite consists of software program instruments for the event of edge machine-learning purposes, together with the likelihood to “bring your own model” in codecs equivalent to TensorFlow Lite, Keras and ONNX.
In addition, the brand new microcontroller helps a rising AI “model zoo,” providing enhanced efficiency and flexibility for numerous purposes. Users can discover the increasing assortment of AI fashions to attain higher outcomes and shorten their time to market.
The STM32N6 gives superior security measures, assembly the most recent requirements with goal SESIP Level 3 and PSA Level 3 certifications.
The STM32N6 has been out there to pick clients since October 2023 and is now able to be provided in excessive volumes. Companies equivalent to LG Electronics are integrating the STM32N6 into their merchandise.
“The STM32N6 delivers remarkable AI performance and provides excellent flexibility in a small silicon package ideal for embedded systems and wearable devices,” mentioned Yehan Ahn, analysis and improvement job chief at LG’s CTO Division. “The inference speed, powered by the groundbreaking Neural-ART Accelerator, has exceeded our expectations and ST’s developer-friendly software tools let us seamlessly integrate our AI models into the MCU.”
“We have rigorously evaluated ST’s latest microcontroller, STM32N6, in our labs, noting its outstanding neural processing performance and excellent power efficiency,” mentioned Seiichi Kawano, principal researcher at Lenovo Research. “This microcontroller represents the beginning of a new era, accelerating our research of ‘AI for all’ technologies at the edge.”
