Product details

Overview

STM32F407IGT6 from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU, operating at 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 protocol bridging and deterministic network timing.

For engineers reviewing the STM32F407IGT6 datasheet, STM32F407IGT6 pinout, STM32F407IGT6 application, or STM32F407IGT6 equivalent, key selection criteria include Ethernet MAC + IEEE 1588v2 hardware timestamping capability, triple 12-bit ADCs (7.2 MSPS interleaved), camera interface (DCMI) bandwidth up to 54 MB/s, and 138 5 V-tolerant I/Os for mixed-voltage system interfacing.

Technical Context

The device integrates an Adaptive Real-time Accelerator (ART Accelerator) enabling zero-wait-state execution from flash memory at 168 MHz, paired with a memory protection unit (MPU) for secure task isolation in RTOS environments. Its multi-AHB bus matrix concurrently services CPU, DMA, and peripheral accesses without contention.

It implements two independent USB PHYs: one full-speed on-chip PHY for OTG_FS and a dedicated high-speed PHY with ULPI interface and dedicated DMA for OTG_HS - enabling simultaneous host/device operation across speed classes. The Ethernet MAC supports MII/RMII physical layer interfaces and hardware-accelerated IEEE 1588v2 timestamping for sub-microsecond time synchronization.

FAQ

What is the maximum operating frequency and associated performance metric of the STM32F407IGT6?

The STM32F407IGT6 operates at a maximum CPU frequency of 168 MHz, delivering 210 DMIPS (Dhrystone 2.1) at 1.25 DMIPS/MHz. This performance is sustained with zero-wait-state execution from flash memory thanks to the integrated ART Accelerator, eliminating performance penalties typically incurred by flash-based instruction fetches.

Does the STM32F407IGT6 support hardware-accelerated IEEE 1588v2 timestamping, and how is it implemented?

Yes, the STM32F407IGT6's embedded 10/100 Ethernet MAC includes dedicated hardware registers and logic for IEEE 1588v2 timestamping. It captures precise transmit/receive timestamps at the PHY boundary with sub-microsecond resolution, supports PTP event packet detection, and enables hardware-based correction of propagation delays - all without CPU involvement or software timing overhead.

How many 5 V-tolerant I/O pins does the STM32F407IGT6 provide, and why is this significant in industrial design?

The STM32F407IGT6 features up to 138 5 V-tolerant I/O pins across its LQFP176 package. This eliminates the need for external level shifters when interfacing with legacy 5 V peripherals such as RS-232 transceivers, optocoupled inputs, or industrial PLC I/O modules - reducing bill-of-materials cost, PCB area, and signal integrity risks in mixed-voltage industrial control systems.

What camera interface capabilities does the STM32F407IGT6 offer, and what is its maximum data throughput?

The STM32F407IGT6 integrates an 8–14-bit parallel Digital Camera Interface (DCMI) supporting up to 54 MB/s throughput. It accepts HSYNC/VSYNC/PCLK and up to 14 data lines (D0–D13), enabling direct connection to CMOS image sensors like OV5640 or MT9V034 without external frame buffers - sufficient for 720p@30 fps raw Bayer data streaming in edge vision applications.
