The newest era of microcontroller items, or MCUs, guarantees to allow builders to push extra synthetic intelligence to edge units reminiscent of robots. STMicroelectronics Worldwide NV this month introduced a brand new MCU sequence that it claimed is its strongest thus far and integrates accelerated machine studying capabilities.
“We’re on the verge of a major transformation on the tiny edge. This transformation includes the rising augmentation or alternative 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 reminiscent of segmentation, classification, and recognition. Sooner or later, they are going to be utilized to new purposes but to be developed.”
Geneva, Switzerland-based STMicroelectronics stated it has extra then 50,000 staffers making semiconductor applied sciences. The built-in system producer works with over 200,000 prospects and 1000’s of companions to design and construct merchandise, programs, and ecosystems that deal with their challenges.

STM32N6 contains new options
STMicroelectronics stated 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 occasions extra machine-learning efficiency than a high-end STM32 MCU at present.
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, stated 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 reasonably priced picture sensors, the corporate stated. This ISP may be configured with the free STM32-ISP-IQTune software program for customizable parameters reminiscent of publicity time, distinction, or colour steadiness.
“[The STM32N6] will make the most of a brand new launch of our distinctive AI software program ecosystem bundle,” stated El-Ouazzane. “This marks the start of an extended journey of AI hardware-accelerated STM32, which is able to allow improvements in purposes and merchandise in methods not doable with another 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.
Obtainable 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’s a widespread false impression that AI is only a giant information middle, power-hungry software,” noticed Tom Hackenberg, principal analyst within the Reminiscence and Computing Group at Yole Group.
“That is now not true,” he stated. “At the moment’s IoT [Internet of Things] edge purposes are hungry for the form of analytics that AI can present. The STM32N6 is a good 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 price of possession in trendy tools.”
STMicroelectronics MCU helps AI, app dev
STMicroelectronics stated its Edge AI Suite contains software program instruments for the event of edge machine-learning purposes, together with the likelihood to “deliver your personal mannequin” in codecs reminiscent of TensorFlow Lite, Keras and ONNX.
As well as, the brand new microcontroller helps a rising AI “mannequin zoo,” providing enhanced efficiency and flexibility for varied purposes. Customers can discover the increasing assortment of AI fashions to attain higher outcomes and shorten their time to market.
The STM32N6 provides superior security measures, assembly the most recent requirements with goal SESIP Degree 3 and PSA Degree 3 certifications.
The STM32N6 has been accessible to pick prospects since October 2023 and is now able to be provided in excessive volumes. Firms reminiscent of LG Electronics are integrating the STM32N6 into their merchandise.
“The STM32N6 delivers outstanding AI efficiency and supplies glorious flexibility in a small silicon bundle superb for embedded programs and wearable units,” stated Yehan Ahn, analysis and improvement process 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 now have rigorously evaluated ST’s newest microcontroller, STM32N6, in our labs, noting its excellent neural processing efficiency and glorious energy effectivity,” stated 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.”
