Macronix International Co., Ltd. announced on March 10, 2025, that STMicroelectronics is utilizing Macronix OctaFlash memory for its new STM32N6 high-performance microcontroller (MCU) platform. This platform integrates the Neural-ART Accelerator NPU, designed for power-efficient edge AI applications.
Macronix's MX25UW1G45G and MX25UM51245G memories have been selected for the STM32N6 Discovery Kits and Nucleo evaluation boards. These high-performance flash memories enable advanced AI computer-vision applicability and a graphical user interface (GUI) experience that simulates 3D-like GUIs and animations.
The STM32N6, based on the Arm Cortex-M55 processing core running at 800 MHz, embeds the ST-developed Neural-ART accelerator, clocked at 1 GHz and providing up to 600 GOPS. The OctaFlash memories deliver instant-on performance and real-time system responsiveness, supporting efficient Execution-In-Place (XIP) and over-the-air (OTA) software updates.
