STMicroelectronics STM32F407VGT6J

Overview

STM32F407VGT6J from STMicroelectronics is a high-performance Arm® Cortex®-M4 32-bit 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 STM32F407VGT6J datasheet, STM32F407VGT6J pinout, STM32F407VGT6J application, or STM32F407VGT6J 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 140 GPIOs with 5 V tolerance - critical for multi-interface edge node designs.

Technical Context

The STM32F407VGT6J 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 for secure firmware updates. Its multi-AHB bus matrix supports concurrent access to flash, SRAM, and peripherals without contention.

It features a dedicated Ethernet DMA engine with MII/RMII physical layer support, hardware-accelerated IEEE 1588v2 timestamping, and a full-duplex DCMI interface capable of 8–14-bit parallel video capture - all synchronized via a shared clock tree managed by multiple PLLs (main PLL, PLLI2S, PLLSAI).

FAQ

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

The STM32F407VGT6J achieves 168 MHz maximum CPU frequency using its main PLL driven by either the 4–26 MHz HSE crystal or the internal 16 MHz HSI RC oscillator. The Adaptive Real-time Accelerator (ART) enables zero-wait-state execution from flash memory at this speed, eliminating instruction fetch bottlenecks. This frequency is sustained under industrial temperature conditions (–40°C to +85°C) with proper VCAP capacitor decoupling per datasheet Section 6.3.2.

Does STM32F407VGT6J support hardware IEEE 1588v2 timestamping?

Yes - the integrated 10/100 Ethernet MAC includes dedicated hardware timestamping logic compliant with IEEE 1588v2 Annex D, capturing transmit/receive packet timestamps with sub-microsecond resolution. Timestamp values are stored in dedicated MAC registers and accessible via DMA or CPU reads, enabling precise time synchronization without software overhead or external timestamping ICs.

Can the DCMI interface operate at full 54 MB/s bandwidth with standard CMOS sensors?

Yes - the DCMI supports 8–14-bit parallel data capture at up to 54 MB/s, validated with common sensors like OV7670 (VGA@30fps = ~27 MB/s) and OV5640 (UXGA@15fps = ~52 MB/s). Achieving full bandwidth requires correct setup of DCMI clock (PCLK), synchronous capture mode, and DMA double-buffering to prevent FIFO overrun - all supported natively in HAL drivers and reference examples.

How many independent CAN 2.0B interfaces does STM32F407VGT6J provide?

The STM32F407VGT6J integrates two fully independent bxCAN 2.0B controllers, each with its own message RAM, filter banks, and dedicated TX/RX pins. Both support bit rates up to 1 Mbps, loopback/self-test modes, and programmable time quanta - enabling dual-bus architectures such as CAN FD gateway bridging or redundant safety networks without external CAN controllers.
