Product details
Overview
STM32F405VGT6V 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 with dedicated DMA, and 10/100 Ethernet MAC with IEEE 1588v2 hardware support - deployed in industrial gateways requiring real-time protocol bridging and multi-interface edge processing.
For engineers reviewing the STM32F405VGT6V datasheet, STM32F405VGT6V pinout, STM32F405VGT6V application, or STM32F405VGT6V equivalent, key selection criteria include Ethernet MAC timing compliance, dual-CAN bus arbitration latency, USB HS PHY integration, DCMI camera interface bandwidth (up to 54 MB/s), and CCM RAM allocation for deterministic ISR execution.
Technical Context
The device integrates an Adaptive Real-time Accelerator (ART) enabling zero-wait-state execution from flash at 168 MHz, paired with a multi-AHB bus matrix for concurrent access to flash, SRAM, and peripherals. Its memory protection unit (MPU) supports region-based privilege enforcement across privileged/unprivileged code and data spaces.
Clock architecture includes three PLLs: main PLL for CPU/system clocks, dedicated audio PLL (PLLI2S) for I2S synchronization, and USB OTG HS PLL with ULPI interface support. The 10/100 Ethernet MAC implements MII/RMII physical layer interfacing with hardware timestamping for IEEE 1588v2 precision time protocol.

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; differs only in Ethernet PHY support - F407 includes integrated 10/100 PHY, F405 requires external PHY. | F407 suits designs needing integrated Ethernet PHY; F405 offers greater flexibility with external PHY selection (e.g., for extended temperature or PoE variants). | Select F405VGT6V when external PHY choice, isolation requirements, or cost-sensitive BOM optimization are priorities. |
| STM32H743VIT6 | Higher-performance Cortex-M7 core (480 MHz), dual-core option, larger flash (2 MB), enhanced security (AES, PKA), but no native DCMI and different pinout. | Suitable for next-gen edge AI inference where compute density outweighs camera interface necessity; not drop-in compatible due to architectural and peripheral differences. | Choose H743 only for new designs requiring >2× CPU performance and cryptographic acceleration - not for F405 migration. |
Compared with STM32F407VGT6, the STM32F405VGT6V trades integrated Ethernet PHY for design flexibility and lower base die cost; versus STM32H743VIT6, it retains DCMI and dual CAN while offering proven toolchain maturity and lower power consumption in mixed-signal industrial environments.

FAQ
What is the maximum operating temperature range for STM32F405VGT6V?
The STM32F405VGT6V is rated for industrial temperature range: –40 °C to +85 °C ambient. This is validated per ST's qualification standards (AEC-Q100 not applicable; industrial-grade reliability testing performed). Thermal derating begins above 70 °C ambient depending on PCB layout and power dissipation.
Does STM32F405VGT6V support USB High-Speed device mode without an external PHY?
No. USB High-Speed (480 Mbps) operation requires an external ULPI PHY connected via the ULPI interface (pins PA3, PB0–PB5, PC0). The chip integrates only a full-speed PHY; HS functionality depends on external PHY compliance with ULPI v1.1 specification.
How many independent CAN controllers does STM32F405VGT6V integrate?
The STM32F405VGT6V integrates two fully independent bxCAN 2.0B controllers (CAN1 and CAN2), each with its own message RAM, filter banks, and transmit/receive FIFOs - enabling simultaneous operation on separate CAN networks without software arbitration overhead.
Is the 64 KB CCM RAM accessible by DMA channels?
No. The 64 KB CCM (Core Coupled Memory) is accessible only by the Cortex-M4 CPU - not by DMA controllers. This ensures deterministic ISR latency and protects critical real-time buffers from DMA contention, as confirmed in Section 3.6 of DS8626 Rev 12.
