STMicroelectronics STM32F746IGT6E

Overview

STM32F746IGT6E 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 Ethernet MAC, USB OTG HS/FS, LCD-TFT controller, and dual CAN 2.0B interfaces - deployed in industrial HMI, medical imaging front-ends, and networked edge gateways.

For engineers reviewing the STM32F746IGT6E datasheet, STM32F746IGT6E pinout, STM32F746IGT6E application, or STM32F746IGT6E equivalent, key selection criteria include its 216 MHz Cortex-M7 core with L1 cache, dual-mode Quad-SPI, Chrom-ART Accelerator™ for GUI rendering, IEEE 1588v2 Ethernet support, and TFBGA100 package compatibility with high-density PCB layouts.

Technical Context

The STM32F746IGT6E implements an adaptive real-time accelerator (ART Accelerator™) with 4 KB instruction and 4 KB data caches, enabling zero-wait-state execution from Flash or external memory. Its AXI-AHB bus matrix supports concurrent high-bandwidth access to Flash, SRAM, and peripherals including FMC, SAI, and SDMMC.

It integrates dual USB controllers (OTG_FS with on-chip PHY and OTG_HS with ULPI interface), a 10/100 Ethernet MAC with dedicated DMA and hardware IEEE 1588v2 timestamping, and a parallel camera interface (DCMI) supporting up to 54 MB/s for real-time image capture.

FAQ

What is the maximum operating frequency and associated performance metric of the STM32F746IGT6E?

The STM32F746IGT6E operates at up to 216 MHz with its ARM Cortex-M7 core, 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 Flash or external memory.

Does the STM32F746IGT6E include an integrated Ethernet physical layer (PHY)?

No, the STM32F746IGT6E integrates only the Ethernet MAC with dedicated DMA and IEEE 1588v2 hardware timestamping. An external PHY (e.g., LAN8742A or DP83848) is required for physical-layer signaling via MII or RMII interface - confirmed in Section 3.31 of DS10916 Rev 5.

How many 12-bit ADC channels does the STM32F746IGT6E support, and what is their aggregate sampling rate?

The device integrates three independent 12-bit ADCs, each capable of 2.4 MSPS. In triple interleaved mode, they achieve a combined sampling rate of 7.2 MSPS across up to 24 channels - verified in Section 3.39 and Table 2 of the datasheet.

What package type and ball pitch does the STM32F746IGT6E use, and how many I/Os are 5 V-tolerant?

STM32F746IGT6E uses a TFBGA100 package (8 × 8 mm) with 0.8 mm ball pitch. It supports up to 166 5 V-tolerant I/Os - explicitly stated in Section 2.2 and Table 10 of DS10916 Rev 5, critical for interfacing with legacy 5 V peripherals.
