STM32N65x Arm®‑based 32-bit MCU

The STM32N6 is based on the Arm® Cortex®-M55 running at 800 MHz, the first CPU to introduce Arm Helium vector processing technology, bringing DSP processing capability to a standard CPU.

The STM32N6 is the first STM32 MCU to embed 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, it enables real-time neural network inference for computer vision and audio applications.

A dedicated computer vision pipeline with a MIPI CSI-2 interface and image signal processing (ISP) ensures compatibility with a wide range of cameras. The STM32N6 also features an H264 hardware encoder and the NeoChrom™ Accelerator for graphics, making it suitable for feature-rich products.

It offers 4.2 Mbytes of contiguous embedded RAM, ideal for neural networks or graphics applications, complemented by high-speed external memory interfaces (hexa-SPI, OCTOSPI, FMC).
