The most recent technology of microcontroller models, or MCUs, guarantees to allow builders to push extra synthetic intelligence to edge gadgets corresponding 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 big transformation on the tiny edge. This transformation entails the growing augmentation or substitute of our prospects’ workloads by AI fashions,” said Remi El-Ouazzane, president of the Microcontrollers, Digital ICs and RF Merchandise Group (MDRF) at STMicroelectronics. “Presently, these fashions are used for duties corresponding 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 system producer works with over 200,000 prospects and 1000’s of companions to design and construct merchandise, programs, and ecosystems that tackle 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 purposes. The corporate asserted that the MCU can ship 600 occasions extra machine-learning efficiency than a high-end STM32 MCU immediately.
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 might be configured with the free STM32-ISP-IQTune software program for customizable parameters corresponding to publicity time, distinction, or shade stability.
“[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 an extended journey of AI hardware-accelerated STM32, which can allow improvements in purposes and merchandise in methods not potential with every 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.
Obtainable 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 information 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. “Immediately’s IoT [Internet of Things] edge purposes are hungry for the sort of analytics that AI can present. The STM32N6 is a good instance of the brand new pattern melding energy-efficient microcontroller workloads with the facility of AI analytics to offer laptop imaginative and prescient and mass sensor-driven efficiency able to nice financial savings within the whole price of possession in fashionable 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 purposes, together with the likelihood to “carry your personal mannequin” in codecs corresponding 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 varied purposes. Customers can discover the increasing assortment of AI fashions to attain higher outcomes and shorten their time to market.
The STM32N6 presents superior safety features, assembly the most recent requirements with goal SESIP Stage 3 and PSA Stage 3 certifications.
The STM32N6 has been obtainable to pick prospects since October 2023 and is now able to be supplied in excessive volumes. Firms corresponding to LG Electronics are integrating the STM32N6 into their merchandise.
“The STM32N6 delivers exceptional AI efficiency and supplies wonderful flexibility in a small silicon package deal splendid for embedded programs and wearable gadgets,” mentioned Yehan Ahn, analysis and improvement 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 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.”
