Product details
Overview
STM32F746NGH6E from STMicroelectronics is a high-performance ARM® Cortex®-M7 32-bit microcontroller with FPU, delivering 462 DMIPS at 216 MHz, featuring 1 MB Flash, 320 KB + 16 KB + 4 KB SRAM, integrated LCD-TFT controller (XGA), dual CAN 2.0B, USB OTG HS/FS, and 10/100 Ethernet MAC - deployed in industrial HMI, medical imaging front-ends, and connected gateway controllers.
For engineers reviewing the STM32F746NGH6E datasheet, STM32F746NGH6E pinout, STM32F746NGH6E application, or STM32F746NGH6E equivalent, key selection criteria include real-time performance (ART Accelerator™ + L1 cache), parallel camera interface (54 MB/s), Chrom-ART Accelerator™ for GUI rendering, IEEE 1588v2 Ethernet support, and dual-mode Quad-SPI for secure firmware storage.
Technical Context
The device implements a tightly coupled Arm Cortex-M7 core with adaptive real-time accelerator (ART) and 4 KB instruction/data caches enabling zero-wait-state execution from flash or external memory. It integrates dual-bank Flash with read-while-write capability and supports boot from internal Flash, system memory, or external interfaces via flexible remap.
Its peripheral architecture features an AXI-AHB bus matrix for concurrent high-bandwidth access to Flash, SRAM, and peripherals; dedicated DMA controllers for Ethernet, USB OTG HS, and LCD-TFT; and dual PLLs (main PLL + audio-specific PLLSAI/PLLI2S) for independent clock domain management across display, audio, and communication subsystems.

FAQ
What is the maximum operating frequency and associated performance metric of the STM32F746NGH6E?
The STM32F746NGH6E operates at a maximum CPU frequency of 216 MHz, achieving 462 DMIPS (Dhrystone 2.1) and 2.14 DMIPS/MHz. This performance is sustained using the ART Accelerator™ and 4 KB instruction/data caches, enabling zero-wait-state execution from embedded Flash or external memory interfaces.
Does the STM32F746NGH6E support hardware-accelerated graphics rendering?
Yes - it integrates the Chrom-ART Accelerator™ (DMA2D), a dedicated 2D graphics processor supporting ARGB8888/RGB565 blending, image scaling, rotation, and color format conversion. This offloads the Cortex-M7 core during GUI composition, enabling smooth animation and fast screen updates without CPU intervention.
What Ethernet capabilities does the STM32F746NGH6E provide?
The device includes a full-featured 10/100 Ethernet MAC with dedicated DMA and hardware support for IEEE 1588v2 Precision Time Protocol, including ingress/egress packet timestamping. It supports both MII and RMII physical layer interfaces and enables deterministic network synchronization critical for industrial automation and time-sensitive networking.
How many analog-to-digital converters does the STM32F746NGH6E integrate, and what are their key specifications?
It integrates three independent 12-bit ADCs, each capable of 2.4 MSPS sampling. In triple interleaved mode, they achieve 7.2 MSPS aggregate throughput across up to 24 channels. All ADCs support hardware oversampling, analog watchdogs, and injected/conversion modes - optimized for motor control current sensing and multi-sensor data acquisition.
