The most recent technology of microcontroller items, or MCUs, guarantees to allow builders to push extra synthetic intelligence to edge gadgets similar to robots. STMicroelectronics Worldwide NV this month introduced a brand new MCU sequence 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 rising augmentation or substitute of our prospects’ workloads by AI fashions,” acknowledged Remi El-Ouazzane, president of the Microcontrollers, Digital ICs and RF Merchandise Group (MDRF) at STMicroelectronics. “At present, these fashions are used for duties similar to segmentation, classification, and recognition. Sooner or later, they are going to be utilized to new purposes 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 prospects and 1000’s of companions to design and construct merchandise, methods, and ecosystems that deal with their challenges.

STM32N6 contains 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 this time.
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 gives as much as 600 GOPS (Giga operations per second), enabling real-time neural community inference for pc 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 similar to publicity time, distinction, or shade steadiness.
“[The STM32N6] will make the most of a brand new launch of our distinctive AI software program ecosystem bundle,” mentioned El-Ouazzane. “This marks the start of a protracted journey of AI hardware-accelerated STM32, which can allow improvements in purposes and merchandise in methods not potential with another embedded processing resolution.”
STMicroelectronics added {that a} devoted pc 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.
Out there 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 frequent false impression that AI is solely an enormous knowledge heart, power-hungry utility,” noticed Tom Hackenberg, principal analyst within the Reminiscence and Computing Group at Yole Group.
“That is now not true,” he mentioned. “At present’s IoT [Internet of Things] edge purposes are hungry for the type of analytics that AI can present. The STM32N6 is a superb instance of the brand new development melding energy-efficient microcontroller workloads with the facility of AI analytics to supply pc imaginative and prescient and mass sensor-driven efficiency able to nice financial savings within the complete price of possession in fashionable gear.”
STMicroelectronics MCU helps AI, app dev
STMicroelectronics mentioned its Edge AI Suite contains software program instruments for the event of edge machine-learning purposes, together with the chance to “deliver your individual mannequin” in codecs similar 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 purposes. Customers can discover the increasing assortment of AI fashions to realize higher outcomes and shorten their time to market.
The STM32N6 gives superior safety features, assembly the newest requirements with goal SESIP Degree 3 and PSA Degree 3 certifications.
The STM32N6 has been accessible to pick out prospects since October 2023 and is now able to be supplied in excessive volumes. Firms similar to LG Electronics are integrating the STM32N6 into their merchandise.
“The STM32N6 delivers exceptional AI efficiency and gives glorious flexibility in a small silicon bundle excellent for embedded methods and wearable gadgets,” mentioned Yehan Ahn, analysis and growth activity 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.”
“We’ve got rigorously evaluated ST’s newest microcontroller, STM32N6, in our labs, noting its excellent neural processing efficiency and glorious 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.”
