Product details
Overview
STM32F405VGT7TR 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. It targets high-performance embedded control in industrial gateways and real-time communication nodes.
For engineers reviewing the STM32F405VGT7TR datasheet, STM32F405VGT7TR pinout, STM32F405VGT7TR application, or STM32F405VGT7TR equivalent, key selection criteria include its dual-CAN + Ethernet + USB OTG HS connectivity, CCM RAM for deterministic ISR execution, ART Accelerator enabling zero-wait-state flash operation, and 140 I/Os with 5 V tolerance - critical for mixed-voltage industrial I/O subsystems.
Technical Context
The device integrates an Adaptive Real-Time (ART) Accelerator that eliminates flash wait states at 168 MHz, paired with a memory protection unit (MPU) for secure task isolation in RTOS environments. Its multi-AHB bus matrix enables concurrent access to flash, SRAM, and peripherals without contention.
It implements two independent USB controllers: OTG_FS with on-chip PHY and OTG_HS with ULPI interface and dedicated DMA, plus a full-featured 10/100 Ethernet MAC supporting MII/RMII and hardware timestamping per IEEE 1588v2 - enabling deterministic time-synchronized networking in PLC and motion-control applications.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-performance Cortex-M4 MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F407VGT6 | Same core, memory, and peripheral set but lacks USB OTG HS ULPI interface; uses internal FS PHY only. | Suitable for USB FS-only designs; cannot support high-speed USB host/device without external PHY. | Select when Ethernet + dual CAN + USB FS suffices and board space/cost constraints exclude ULPI routing. |
| STM32H743VIT6 | Dual-core (Cortex-M7 + Cortex-M4), 480 MHz, 2 MB flash, 1 MB RAM, enhanced crypto, no DCMI; requires different toolchain and power design. | Targeted at higher-tier edge AI and real-time HMI; overqualified for pure industrial comms where F405's cost/performance ratio dominates. | Choose only if >200 DMIPS, dual-core isolation, or hardware crypto acceleration are mandatory - not for drop-in replacement. |
Compared with STM32F407VGT6, the STM32F405VGT7TR adds USB OTG HS ULPI for high-bandwidth peripheral attachment, while versus STM32H743VIT6 it trades raw performance for lower power, simpler power sequencing, and proven ecosystem maturity in industrial field deployments.

FAQ
What is the maximum operating temperature range for STM32F405VGT7TR?
The STM32F405VGT7TR is rated for industrial temperature range: –40 °C to +85 °C ambient. This is validated per datasheet Section 6.3.1 and applies to all LQFP100 packages. Thermal derating begins above 85 °C ambient, and junction temperature must remain below 125 °C under sustained load with proper PCB copper pour and thermal vias.
Does STM32F405VGT7TR support external memory expansion?
Yes - it includes a Flexible Static Memory Controller (FSMC) supporting NOR, PSRAM, NAND, and CompactFlash memories with programmable timing. The FSMC provides up to 16-bit data bus and 26-bit address bus, enabling direct connection to external displays, FPGA co-processors, or legacy memory-mapped peripherals without glue logic.
How many USB interfaces does STM32F405VGT7TR integrate?
It integrates two independent USB controllers: one USB OTG Full-Speed (OTG_FS) with integrated PHY, and one USB OTG High-Speed (OTG_HS) with ULPI interface and dedicated DMA channel. OTG_HS requires external ULPI PHY (e.g., TUSB1210), while OTG_FS operates standalone.
Is the STM32F405VGT7TR pin-compatible with other STM32F40x variants in LQFP100?
Yes - all STM32F405xx and STM32F407xx devices in LQFP100 (100-pin) package share identical pinouts per datasheet Table 7 and Section 4. This includes STM32F405VGT6/7 and STM32F407VGT6/7. Function mapping differs only in peripheral enablement (e.g., OTG_HS pins are no-connect on F407), not physical layout.
