STMicroelectronics STM32F407VGT7

Overview

STM32F407VGT7 from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller 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 protocol bridging and deterministic network timing.

For engineers reviewing the STM32F407VGT7 datasheet, STM32F407VGT7 pinout, STM32F407VGT7 application, or STM32F407VGT7 equivalent, key selection criteria include Ethernet MAC + IEEE 1588v2 hardware timestamping capability, triple 12-bit ADCs (7.2 MSPS interleaved), camera interface (DCMI) bandwidth (54 MB/s), ART Accelerator-enabled zero-wait-state flash execution, and 138 5 V-tolerant I/Os for mixed-voltage system interfacing.

Technical Context

The STM32F407VGT7 integrates an Arm Cortex-M4 core with single-precision FPU and DSP extensions, coupled with ST's Adaptive Real-Time (ART) Accelerator enabling deterministic 0-wait-state execution from flash at 168 MHz. Its memory subsystem includes 1 MB of embedded flash, 192 KB main SRAM, 4 KB backup SRAM, and 64 KB CCM RAM tightly coupled to the CPU for low-latency data access.

Peripherals are organized across three AHB buses and two APB domains, supporting concurrent high-bandwidth operations: Ethernet MAC with dedicated DMA and hardware IEEE 1588v2 timestamping, dual USB OTG controllers (one HS with ULPI/PHY, one FS with on-chip PHY), and DCMI with 8–14-bit parallel capture up to 54 MB/s - all synchronized via a multi-source clock tree with four PLLs (main, audio, USB, and system).

FAQ

What is the maximum operating frequency and how is it achieved?

The STM32F407VGT7 achieves 168 MHz using its main PLL driven by either the 4–26 MHz HSE crystal or 16 MHz HSI RC oscillator. The ART Accelerator enables zero-wait-state execution from flash memory at this frequency, verified per DS8626 Rev 12 Section 3.2. This eliminates instruction fetch stalls and ensures deterministic timing for hard real-time tasks.

Does the part support hardware-based IEEE 1588v2 timestamping?

Yes - the integrated 10/100 Ethernet MAC includes dedicated IEEE 1588v2 hardware timestamping logic with sub-100 ns resolution, as specified in DS8626 Rev 12 Section 3.28. It captures transmit/receive packet timestamps in real time without CPU intervention, enabling precise PTP slave clock synchronization in industrial networks.

What are the key differences between the VGT7 and IGK6 variants?

The STM32F407VGT7 uses LQFP100 packaging (100 pins), while STM32F407IGK6 uses LQFP176 (176 pins). Both share identical core architecture, flash/RAM size, and peripheral sets, but the IGK6 provides more GPIOs (140 vs. 100), additional FSMC address/data lines, and extra timer/ADC channels - confirmed in Table 1 and Section 7 of DS8626 Rev 12.

Is the DCMI interface capable of handling 720p30 video capture?

Yes - the DCMI supports up to 54 MB/s bandwidth (DS8626 Rev 12 Section 3.32), sufficient for 720p (1280×720) at 30 fps with 16-bit RGB565 (≈44 MB/s). Pixel clock (PIXCLK) operates up to 54 MHz, and synchronous capture with HSYNC/VSYNC ensures frame-accurate timing without external FIFOs.
