The most recent era of microcontroller items, or MCUs, guarantees to allow builders to push extra synthetic intelligence to edge gadgets comparable to robots. STMicroelectronics Worldwide NV this month introduced a brand new MCU collection that it claimed is its strongest so far and integrates accelerated machine studying capabilities.
“We’re on the verge of a major transformation on the tiny edge. This transformation entails the growing augmentation or alternative of our clients’ workloads by AI fashions,” said Remi El-Ouazzane, president of the Microcontrollers, Digital ICs and RF Merchandise Group (MDRF) at STMicroelectronics. “At present, these fashions are used for duties comparable to segmentation, classification, and recognition. Sooner or later, they are going to be utilized to new functions but to be developed.”
Geneva, Switzerland-based STMicroelectronics mentioned it has extra then 50,000 staffers making semiconductor applied sciences. The built-in machine producer works with over 200,000 clients and hundreds of companions to design and construct merchandise, methods, and ecosystems that deal with their challenges.

STM32N6 consists of new options
STMicroelectronics mentioned its STM32N6 collection is the primary MCU to embed its proprietary neural processing unit (NPU), the Neural-ART accelerator, which it designed for power-efficient edge AI functions. The firm asserted that the MCU can ship 600 occasions extra machine-learning efficiency than a high-end STM32 MCU right now.
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 functions, mentioned STMicroelectronics.
For the primary time on an MCU, the STM32N6 incorporates a picture sign processor (ISP) that gives direct sign processing, enabling the usage of easy and reasonably priced picture sensors, the corporate mentioned. This ISP could be configured with the free STM32-ISP-IQTune software program for customizable parameters comparable to publicity time, distinction, or colour steadiness.
“[The STM32N6] will make the most of a brand new launch of our distinctive AI software program ecosystem package deal,” mentioned El-Ouazzane. “This marks the start of a protracted journey of AI hardware-accelerated STM32, which is able to allow improvements in functions and merchandise in methods not potential with some other embedded processing resolution.”
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.
Accessible in six completely 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’s a widespread false impression that AI is only a giant knowledge middle, power-hungry utility,” noticed Tom Hackenberg, principal analyst within the Reminiscence and Computing Group at Yole Group.
“That is not true,” he mentioned. “At the moment’s IoT [Internet of Things] edge functions are hungry for the form of analytics that AI can present. The STM32N6 is a superb instance of the brand new development melding energy-efficient microcontroller workloads with the ability of AI analytics to supply laptop imaginative and prescient and mass sensor-driven efficiency able to nice financial savings within the complete value of possession in trendy tools.”
STMicroelectronics MCU helps AI, app dev
STMicroelectronics mentioned its Edge AI Suite consists of software program instruments for the event of edge machine-learning functions, together with the chance to “carry your personal mannequin” in codecs comparable to TensorFlow Lite, Keras and ONNX.
As well as, the brand new microcontroller helps a rising AI “mannequin zoo,” providing enhanced efficiency and flexibility for numerous functions. Customers can discover the increasing assortment of AI fashions to realize higher outcomes and shorten their time to market.
The STM32N6 presents superior safety features, assembly the newest requirements with goal SESIP Stage 3 and PSA Stage 3 certifications.
The STM32N6 has been out there to pick out clients since October 2023 and is now able to be supplied in excessive volumes. Corporations comparable to LG Electronics are integrating the STM32N6 into their merchandise.
“The STM32N6 delivers outstanding AI efficiency and supplies wonderful flexibility in a small silicon package deal ideally suited for embedded methods and wearable gadgets,” mentioned Yehan Ahn, analysis and improvement job chief at LG’s CTO Division. “The inference pace, powered by the groundbreaking Neural-ART Accelerator, has exceeded our expectations and ST’s developer-friendly software program instruments allow us to seamlessly combine our AI fashions into the MCU.”
“Now we have rigorously evaluated ST’s newest microcontroller, STM32N6, in our labs, noting its excellent neural processing efficiency and wonderful energy effectivity,” mentioned Seiichi Kawano, principal researcher at Lenovo Analysis. “This microcontroller represents the start of a brand new period, accelerating our analysis of ‘AI for all’ applied sciences on the edge.”
