Product details
Overview
STM32F405RGT6V 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), USB OTG HS/FS, 10/100 Ethernet MAC, and dual CAN 2.0B interfaces - deployed in industrial gateways requiring real-time connectivity and deterministic control.
For engineers reviewing the STM32F405RGT6V datasheet, STM32F405RGT6V pinout, STM32F405RGT6V application, or STM32F405RGT6V equivalent, key selection criteria include its 168 MHz Cortex-M4+FPU core, integrated Ethernet MAC with IEEE 1588v2 hardware support, triple 12-bit ADCs (7.2 MSPS interleaved), camera interface (DCMI) up to 54 MB/s, and LQFP64 package compatibility with legacy STM32F40x designs.
Technical Context
The STM32F405RGT6V implements an Adaptive Real-time Accelerator (ART Accelerator) enabling zero-wait-state execution from flash memory at 168 MHz, paired with a memory protection unit (MPU) for secure task isolation in RTOS environments. Its multi-AHB bus matrix concurrently services CPU, DMA, and peripheral accesses without contention.
It integrates dual USB controllers - one full-speed OTG with on-chip PHY, another high-speed/full-speed OTG with dedicated DMA and ULPI support - alongside a 10/100 Ethernet MAC with MII/RMII physical layer interface and hardware-accelerated IEEE 1588v2 timestamping for precision time synchronization in industrial automation networks.

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/peripherals but adds LCD-TFT controller and additional Ethernet features; 100-pin LQFP package | Requires larger PCB footprint and lacks pin compatibility with LQFP64 layout | Select when TFT display interface or extra Ethernet PHY signals are needed; not drop-in replaceable |
| STM32H743VIT6 | Cortex-M7 core (480 MHz), dual-core capability, enhanced security (firewall, TCM), 2 MB flash, but no native DCMI | Higher performance and security, but requires redesign for camera interface (uses MIPI DSI or external bridge) | Choose for next-gen designs needing >300 DMIPS and PSA Level 2 certification; not compatible for DCMI-dependent legacy systems |
Compared with STM32F407VGT6, the STM32F405RGT6V offers identical real-time performance in a space-constrained LQFP64 form factor, while the STM32H743VIT6 delivers higher compute density at the cost of camera interface removal and increased power/complexity - making the F405RGT6V optimal for cost-sensitive, size-limited industrial edge nodes with parallel imaging requirements.

FAQ
What is the maximum operating frequency and associated DMIPS rating?
The STM32F405RGT6V operates at up to 168 MHz with an integer performance rating of 210 DMIPS (Dhrystone 2.1), achieved using the ART Accelerator for zero-wait-state flash execution. This rating assumes use of the embedded FPU and DSP instruction set, validated under standard test conditions (VDD = 3.3 V, TA = 25 °C).
Does this MCU support hardware-accelerated IEEE 1588v2 timestamping?
Yes - the integrated 10/100 Ethernet MAC includes dedicated hardware timestamping logic compliant with IEEE 1588v2 Annex D, enabling sub-microsecond precision for PTP synchronization without CPU intervention or external timing ICs.
What are the key differences between the STM32F405RGT6V and STM32F407VGT6?
The STM32F405RGT6V and STM32F407VGT6 share identical core, memory, USB, CAN, and ADC specifications, but the F407 adds an LCD-TFT controller and enhanced Ethernet features (e.g., hardware checksum offload). The F407 uses LQFP100 packaging, making it physically incompatible with the LQFP64 footprint of the F405RGT6V.
Is the DCMI interface capable of supporting VGA resolution at 30 fps?
Yes - the DCMI supports 8- to 14-bit parallel data capture at up to 54 MB/s, sufficient for raw VGA (640×480×2 bytes/pixel = ~61.4 MB/s at 30 fps); actual achievable frame rate depends on sensor timing, DMA configuration, and memory bandwidth allocation to CCM and main SRAM.
