Product details
Overview
STM32F407VET6TR from STMicroelectronics is a high-performance Arm® Cortex®-M4 32-bit microcontroller with FPU, operating at up to 168 MHz (210 DMIPS), featuring 512 KB 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 STM32F407VET6TR datasheet, STM32F407VET6TR pinout, STM32F407VET6TR application, or STM32F407VET6TR 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 STM32F407VET6TR implements a dual-bus AHB matrix architecture supporting concurrent access to flash, SRAM, and peripherals - enabling deterministic execution of time-critical Ethernet and CAN traffic handlers without bus contention. Its ART Accelerator eliminates flash wait states at 168 MHz, while the CCM RAM provides zero-wait-state data storage for critical ISR stacks and real-time buffers.
It integrates dedicated hardware blocks including IEEE 1588v2-compliant Ethernet MAC with hardware timestamping, two independent CAN 2.0B controllers with programmable bit timing, and a parallel DCMI interface supporting 8–14-bit YUV/RGB capture at up to 54 MB/s - all synchronized via a multi-source clock tree with four PLLs (main, audio, USB, and RTC).

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-performance MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F407IGT6 | LQFP176 package (24 × 24 mm), 1 MB flash, same peripheral set - adds 36 extra GPIOs and 2 additional USARTs. | Better suited for complex HMI + connectivity designs requiring >100 I/Os and dual Ethernet/CAN redundancy. | Select when board layout accommodates larger footprint and firmware requires >512 KB flash for OTA updates + secure bootloader. |
| STM32H743VIT6 | Cortex-M7 core (480 MHz), dual-core option, 2 MB flash, enhanced crypto accelerators, no DCMI - higher DMIPS but different pinout and power profile. | Targeted at AI-edge inference (e.g., TinyML classification) where raw compute outweighs parallel camera interface needs. | Choose only if migrating to M7 architecture is acceptable; not pin-compatible and requires full PCB redesign. |
Compared with STM32F407IGT6, the STM32F407VET6TR trades I/O count and flash capacity for compact LQFP100 packaging and lower thermal density - ideal for space-constrained gateways. Versus STM32H743VIT6, it retains DCMI and IEEE 1588v2 hardware while offering proven toolchain stability and lower BOM cost for deterministic real-time applications.

FAQ
What is the maximum operating frequency and associated performance metric?
The STM32F407VET6TR operates at up to 168 MHz with an integer performance rating of 210 DMIPS (Dhrystone 2.1), measured at 1.25 DMIPS/MHz. This reflects sustained execution speed with ART Accelerator enabled and flash wait states eliminated - verified per ST's DS8626 Rev 12 test conditions at 25°C and 3.3 V supply.
Does this MCU support hardware timestamping for Precision Time Protocol (PTP)?
Yes - the integrated 10/100 Ethernet MAC includes IEEE 1588v2-compliant hardware timestamping with sub-nanosecond resolution. It supports both ingress and egress timestamp insertion/removal in Ethernet frames, enabling deterministic PTP slave operation without software intervention or CPU overhead.
What are the supported camera interface standards and maximum data rates?
The DCMI interface supports 8–14-bit parallel YUV/RGB formats with programmable polarity and timing. At maximum configuration (14-bit, 54 MHz PCLK), it achieves 54 MB/s throughput - sufficient for VGA@60 fps (640×480×2 bytes×60 = 36.9 MB/s) or QVGA@200 fps, validated in ST Application Note AN3966.
How many independent CAN 2.0B controllers does the STM32F407VET6TR integrate?
It integrates two fully independent bxCAN 2.0B controllers (CAN1 and CAN2), each with its own message RAM, filter banks, and programmable bit timing registers. Both support listen-only mode, automatic wakeup, and loopback self-test - confirmed in Section 3.29 of DS8626 Rev 12.
