Product details

Overview

STM32F405VGT6TR 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, USB OTG HS/FS, and 10/100 Ethernet MAC with IEEE 1588v2 support - deployed in industrial gateways requiring real-time connectivity and deterministic communication.

For engineers reviewing the STM32F405VGT6TR datasheet, STM32F405VGT6TR pinout, STM32F405VGT6TR application, or STM32F405VGT6TR equivalent, key selection criteria include its 144-pin LQFP package, triple 12-bit ADCs (7.2 MSPS interleaved), camera interface (DCMI) supporting 54 MB/s, and hardware crypto acceleration via RNG and CRC units.

Technical Context

The STM32F405VGT6TR integrates an Adaptive Real-Time Accelerator (ART Accelerator) enabling zero-wait-state execution from flash at 168 MHz, paired with a memory protection unit (MPU) for secure task isolation in RTOS environments. Its multi-AHB bus matrix concurrently serves CPU, DMA, and peripherals without contention.

It implements dual USB controllers - one full-speed OTG with on-chip PHY, another high-speed OTG with dedicated DMA and ULPI support - alongside a fully featured Ethernet MAC with MII/RMII physical layer interface and hardware timestamping for time-sensitive networking.

Equivalent & Alternatives

The following parts are listed as comparable options for similar microcontroller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STM32F407VGT6	Same core, memory, and peripheral set but includes integrated Ethernet PHY (RMII only); lacks USB HS ULPI interface.	Better suited for cost-sensitive Ethernet-only designs where external PHY is undesirable; unsuitable for USB HS host applications.	Select when Ethernet is primary interface and USB HS is not required - reduces BOM count by eliminating external PHY.
STM32H743VIT6	Higher-performance Cortex-M7 (480 MHz), dual-core option, larger flash (2 MB), enhanced crypto (AES-256, SHA-256), no DCMI.	Targets AI inference at edge and high-throughput industrial vision where STM32F405's 168 MHz and DCMI are insufficient.	Choose for next-generation designs needing >2× CPU throughput and hardware security extensions - requires PCB redesign due to LQFP176 package.

Compared with STM32F407VGT6, the STM32F405VGT6TR offers identical MCU functionality but excludes the internal Ethernet PHY - enabling flexible PHY selection and lower EMI in mixed-signal layouts. Versus STM32H743VIT6, it trades raw compute for proven real-time determinism, lower power, and mature toolchain support in established industrial platforms.

FAQ

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

The STM32F405VGT6TR achieves 168 MHz maximum CPU frequency using its internal PLL driven by either the 4–26 MHz HSE crystal oscillator or the 16 MHz HSI RC oscillator. The ART Accelerator ensures zero-wait-state execution from flash memory at this speed, validated across voltage (1.8–3.6 V) and temperature (–40°C to +85°C) ranges per DS8626 Rev 12.

Does this part support USB High-Speed device/host functionality?

Yes - the STM32F405VGT6TR integrates a dedicated USB 2.0 high-speed/full-speed OTG controller with on-chip full-speed PHY and ULPI interface for external high-speed PHY connection. It supports HS device/host/OTG roles with dedicated DMA, enabling bandwidth-intensive applications like USB video class (UVC) streaming.

What are the key differences between STM32F405 and STM32F407 variants?

The STM32F405VGT6TR and STM32F407VGT6 share identical CPU, memory, timers, ADCs, and communication peripherals. The primary difference is that the F407 includes an integrated Ethernet MAC + PHY (supporting both MII and RMII), whereas the F405 provides only the MAC layer - requiring an external PHY for Ethernet operation.

Is the LQFP144 package RoHS-compliant and lead-free?

Yes - the STM32F405VGT6TR in LQFP144 package is ECOPACK2-compliant, meeting RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. It uses lead-free matte tin plating and is rated for peak reflow temperatures up to 260°C per J-STD-020, with full traceability documentation available upon request.
