Product details
Overview
STM32F405VGT6 from STMicroelectronics is a high-performance Arm® Cortex®-M4 32-bit microcontroller with FPU, operating at 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 timing.
For engineers reviewing the STM32F405VGT6 datasheet, STM32F405VGT6 pinout, STM32F405VGT6 application, or STM32F405VGT6 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-accelerated crypto primitives including TRNG and CRC unit.
Technical Context
The STM32F405VGT6 integrates an Adaptive Real-time Accelerator (ART Accelerator) enabling zero-wait-state execution from flash memory at 168 MHz, alongside a Memory Protection Unit (MPU) for secure task isolation in RTOS environments. Its multi-AHB bus matrix supports concurrent access to flash, SRAM, and peripherals without contention.
It implements two independent USB controllers: OTG_FS with on-chip full-speed PHY and OTG_HS with dedicated DMA, ULPI interface, and external high-speed PHY support. The Ethernet MAC includes MII/RMII physical layer support and hardware timestamping for IEEE 1588v2 precision time protocol applications.

Pinout & Package
LQFP144 package with 144 leads, 20 × 20 mm body, 0.5 mm lead pitch, exposed thermal pad (EPAD) on underside for enhanced thermal dissipation in continuous operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VSS, VSSA | Power supply and ground | Separate analog/digital domains ensure clean ADC/DAC reference; VDDA must be ≥ VDD − 0.3 V for valid analog operation |
| PA0–PA15, PB0–PB15, etc. | General-purpose I/O | 140 total GPIOs; 138 support 5 V tolerance - enables direct interfacing with legacy 5 V logic without level shifters |
| PA11/PA12, PB14/PB15 | USB OTG FS/HS D+/D− | Dedicated differential pairs with internal pull-ups; OTG_FS uses PA11/PA12; OTG_HS uses PB14/PB15 (ULPI mode) or PA11/PA12 (FS fallback) |
| PC1–PC4, PD0–PD7 | Ethernet MAC interface | MII/RMII signals (TXD0–TXD3, RXD0–RXD3, TX_EN, CRS_DV, REF_CLK); RMII reduces pin count to 9 pins vs. 16 for MII |
| PD3–PD12 | DCMI data bus (D0–D11) | 12-bit parallel camera interface supporting up to 54 MB/s throughput; synchronous capture with HSYNC/VSYNC/PIXCLK inputs |
Key Features

| CCM RAM | 64 KB core-coupled memory accessible only by CPU (not DMA) - ideal for time-critical ISR stacks and real-time control buffers |
| Flexible Static Memory Controller (FSMC) | Supports NOR/NAND/PSRAM/SRAM/CompactFlash with programmable timing - enables direct attachment of external displays, FPGA co-processors, or legacy memory modules |
| Hardware Crypto Acceleration | Integrated TRNG and CRC calculation unit - accelerates secure boot, firmware signature verification, and data integrity checks without CPU overhead |
| Low-power Modes | Sleep/Stop/Standby with RTC + 20×32-bit backup registers + optional 4 KB backup SRAM - maintains state during battery-backed operation for metering or alarm systems |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-performance MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F407VGT6 | Includes Ethernet MAC + MII/RMII; identical core/peripherals except adds Ethernet PHY interface signals | Required where native 10/100 Ethernet PHY integration is needed (e.g., industrial switches) | Select if Ethernet PHY routing is feasible; otherwise STM32F405VGT6 saves PCB area and cost |
| STM32H743VIT6 | Dual-core (Cortex-M7 + Cortex-M4); 480 MHz M7 core; 2 MB flash; no DCMI; different pinout and power architecture | Targeted at AI inference edge nodes needing >500 DMIPS and dual-core RTOS partitioning | Choose only when performance headroom exceeds 2× and legacy peripheral compatibility is not required |
Compared with STM32F407VGT6, the STM32F405VGT6 omits Ethernet PHY pins but retains full MAC functionality - reducing BOM cost and layout complexity while maintaining identical software compatibility.

FAQ
What is the maximum operating temperature range for STM32F405VGT6?
The STM32F405VGT6 is rated for industrial temperature range: –40 °C to +85 °C ambient. Thermal characteristics in the datasheet (DS8626 Rev 12, Section 7.8) specify θJA = 25.5 °C/W for LQFP144 package, requiring minimum 2 cm² copper pour under EPAD for sustained 168 MHz operation at +85 °C.
Does STM32F405VGT6 support external memory expansion?
Yes - it integrates a Flexible Static Memory Controller (FSMC) supporting NOR, PSRAM, NAND, SRAM, and CompactFlash™ with configurable address/data bus widths and timing parameters. Up to 64 MB of external memory can be mapped into four banks, each with independent wait-state and burst settings.
Can STM32F405VGT6 run FreeRTOS with Ethernet and USB stacks simultaneously?
Yes - validated ST reference designs (e.g., STM32CubeF4 middleware) demonstrate concurrent FreeRTOS tasks managing lwIP Ethernet TCP/IP stack, USB CDC ACM host, and FATFS SDIO file system. Critical sections use MPU-protected memory regions and priority-based NVIC preemption.
Is the DCMI interface capable of progressive scan video capture?
Yes - the Digital Camera Interface supports progressive scan formats up to UXGA (1600×1200) at 15 fps via 12-bit parallel bus (D0–D11) with hardware synchronization (HSYNC/VSYNC/PIXCLK). Frame buffer DMA transfers are supported directly to CCM RAM or main SRAM with scatter-gather chaining.
