Product details

Overview

STM32F746G-DISCO from STMicroelectronics is a full-featured Discovery kit centered on the STM32F746NGH6 Arm® Cortex®-M7 microcontroller (1 MB Flash, 340 KB RAM, BGA216), integrated with a 4.3" 480×272 RGB TFT LCD with capacitive touch, Ethernet PHY, USB OTG HS/FS, SAI audio codec, dual MEMS microphones, 128-Mbit Quad-SPI flash, and 128-Mbit SDRAM.

For engineers reviewing the STM32F746G-DISCO datasheet, STM32F746G-DISCO pinout, STM32F746G-DISCO application, or STM32F746G-DISCO equivalent, this board serves as a production-ready reference design for graphics-rich embedded applications requiring real-time audio, multi-sensor fusion, high-speed connectivity, and secure firmware development.

Technical Context

The board implements the STM32F746NGH6 MCU in a fully routed, debug-ready configuration with hardware-accelerated graphics (Chrom-ART Accelerator™), floating-point and DSP instructions, and dual-bank Flash enabling seamless firmware updates. It integrates IEEE 802.3-compliant Ethernet MAC+PHY, USB OTG with dual-role capability (host/peripheral), and SAI interface driving an external audio codec.

Power architecture supports flexible sourcing (ST-LINK VBUS, micro-USB, or external 5 V/3.3 V), with regulated outputs for external peripherals. ARDUINO® Uno V3 headers and dedicated expansion connectors (camera, microSD, RF-EEPROM) enable rapid prototyping across industrial HMI, audio gateway, and edge AI sensor node use cases.

FAQ

Does STM32F746G-DISCO include the target MCU soldered and functional?

Yes. The board features the STM32F746NGH6 MCU (1 MB Flash, 340 KB RAM, BGA216 package) fully assembled and tested. It operates out-of-box with preloaded demonstration firmware accessible via the onboard LCD and touch interface, and is programmable/debuggable using the integrated ST-LINK/V2-1 debugger without external hardware.

Can the on-board SDRAM be used for frame buffer storage in graphics applications?

Yes. The 128-Mbit SDRAM (64 Mbits accessible) is directly connected to the MCU's Flexible Memory Controller (FMC) and configured in the STM32CubeF7 examples for use as a frame buffer for the RGB LCD. It supports double-buffering and DMA-driven refresh, enabling smooth 60 Hz UI rendering without CPU overhead.

Is Ethernet functionality operational without external PHY components?

Yes. The board integrates a compliant IEEE 802.3 PHY (DP83848 or equivalent) with magnetics and RJ45 connector. The STM32F746NGH6's embedded Ethernet MAC interfaces directly to this PHY, and LwIP-based TCP/IP stack examples are included in the STM32CubeF7 software package for immediate network connectivity testing.

What audio interfaces are supported natively by the board?

The board supports SAI (Serial Audio Interface) for I²S/TDM audio codec interfacing, SPDIF RCA input for digital audio ingestion, analog line-in/line-out jacks, and stereo speaker outputs driven by the onboard audio codec. Dual MEMS microphones provide far-field audio capture with PDM-to-I²S conversion handled by the MCU's DFSDM peripheral.
