STM32N6 Series MCUs
STMicroelectronics MCUs redefine performance for industrial and consumer applications
Image of STMicroelectronics STM32N6 Series MCUsThe STMicroelectronics STM32N6 is based on the Arm® Cortex®-M55 running at 800 MHz. The Cortex-M55 is the first MCU to introduce the Arm Helium vector processing technology, bringing DSP processing capability to a standard MCU.
The STM32N6 is the first STM32 MCU that embeds the ST Neural-ART Accelerator™, an in-house developed neural processing unit (NPU) engineered for power-efficient edge AI applications. Clocked at 1 GHz and providing up to 600 GOPS of processing capabilities, it allows for real-time neural network inference of computer vision and audio applications.
A dedicated computer vision pipeline consisting of a MIPI CSI-2® interface paired with image signal processing assures large compatibility with cameras on the market. An H264 hardware encoder, JPEG codec, and the NeoChrom™ accelerator for graphics allow the STM32N6 to be deployed in demanding feature-rich products.
