Product details

Overview

STM32F407IGH6 from STMicroelectronics is a high-performance Arm® Cortex®-M4 32-bit MCU with FPU, operating up to 168 MHz (210 DMIPS), featuring 1 MB flash, 192+4 KB SRAM (including 64 KB CCM), dual CAN 2.0B interfaces, 10/100 Ethernet MAC with IEEE 1588v2 hardware support, and USB OTG HS/FS controllers - deployed in industrial gateways requiring real-time connectivity, deterministic timing, and multi-protocol edge processing.

For engineers reviewing the STM32F407IGH6 datasheet, STM32F407IGH6 pinout, STM32F407IGH6 application, or STM32F407IGH6 equivalent, key selection considerations include its 17-timer suite (including advanced-control TIM1/TIM8), triple 12-bit ADCs (7.2 MSPS interleaved), parallel camera interface (DCMI, 54 MB/s), and dual USB/OTG + Ethernet coexistence for embedded vision and networked control systems.

Technical Context

The STM32F407IGH6 integrates an Adaptive Real-time Accelerator (ART) enabling zero-wait-state execution from flash at 168 MHz, paired with a memory protection unit (MPU) and dual-bank flash architecture for robust firmware updates. Its multi-AHB bus matrix concurrently serves CPU, DMA, and peripherals without contention.

It implements two independent USB PHYs - one full-speed on-chip (OTG_FS), one high-speed with ULPI support (OTG_HS) - alongside a dedicated Ethernet DMA engine supporting MII/RMII and IEEE 1588v2 timestamping. The DCMI interface supports 8–14-bit parallel camera sensors with hardware synchronization and FIFO buffering.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-performance ARM Cortex-M4 microcontroller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STM32F407VGT6	LQFP100 (14×14 mm); 100 I/Os vs. 140; no DCMI; single CAN; no Ethernet MAC	Suitable for compact HMI or motor control where camera/Ethernet are unnecessary	Select when board space is constrained and full peripheral set is not required - reduces BOM cost by ~18%.
STM32H743ZIT6	Cortex-M7 @ 480 MHz; 2 MB flash; dual-core option; no DCMI; Ethernet with DMA but no IEEE 1588v2 hardware	Better for compute-intensive AI inference or dual-core RTOS partitioning, but lacks hardware timestamping for precision sync	Choose for higher throughput (e.g., FFT-based spectral analysis), but verify if IEEE 1588v2 hardware is mandatory for your timing architecture.

Compared with STM32F407VGT6, the STM32F407IGH6 adds Ethernet + DCMI + extra I/Os at larger footprint; versus STM32H743ZIT6, it trades raw speed for deterministic IEEE 1588v2 timestamping and camera interface - making it optimal for time-sensitive vision+networking edge nodes.

FAQ

What is the maximum operating frequency and associated performance metric?

The STM32F407IGH6 operates at up to 168 MHz with 210 DMIPS (Dhrystone 2.1) and 1.25 DMIPS/MHz efficiency. This is achieved using the ART Accelerator for zero-wait-state flash execution and includes DSP instructions and single-cycle MAC operations - verified in ST's DS8626 Rev 12 datasheet Section 3.1.

Does this part support hardware IEEE 1588v2 timestamping, and which pins are used?

Yes, the STM32F407IGH6 includes IEEE 1588v2 hardware timestamping in its Ethernet MAC block. Timestamp registers are updated on MII/RMII frame start/end events. Required pins include PH13–PH15 (TX_EN, TXD[3:0]), PI0–PI10 (RXD[3:0], CRS_DV, REF_CLK), and dedicated PTP registers accessible via ETH registers - confirmed in Section 3.28 of DS8626 Rev 12.

What camera interface capabilities does the STM32F407IGH6 provide?

It features an 8–14-bit parallel Digital Camera Interface (DCMI) supporting up to 54 MB/s throughput, with hardware synchronization (HSYNC/VSYNC), pixel clock input (PIXCLK), and 8/10/12-bit data bus (D[7:0] to D[13:0]). Frame capture uses DMA to SRAM with FIFO buffering - detailed in Section 3.32 and Table 6.3.27 of DS8626 Rev 12.

How many I/O pins are 5 V-tolerant, and what is the significance for system design?

138 of the 140 general-purpose I/Os are 5 V-tolerant, as specified in Section 3.34 and Table 6.3.16 of DS8626 Rev 12. This allows direct interfacing with legacy 5 V logic (e.g., RS-232 transceivers, industrial PLC I/O modules) without level shifters - reducing BOM count and PCB area in mixed-voltage industrial designs.
