STM32N6 High Performance Microcontrollers

STMicroelectronics STM32N6 High-Performance Microcontrollers are powered by the Arm^® Cortex^®-M55, running at 800MHz. These MCUs introduce Arm Helium™ vector processing for DSP capabilities and feature the ST Neural-ART accelerator™, an in-house NPU designed for power-efficient edge AI applications, with a 1GHz clock speed and up to 600 GOPS. STMicroelectronics STM32N6 MCUs support real-time neural network inference for computer vision and audio tasks. A MIPI CSI2 interface and image signal processing ensure broad camera compatibility, while an H.264 encoder, JPEG codec, and NeoChrom™ Accelerator for graphics enable deployment in feature-rich products.
