STMicroelectronics STM32F407VGT6TR

Overview

STM32F407VGT6TR 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, 10/100 Ethernet MAC with IEEE 1588v2 hardware support, and USB OTG HS/FS controllers - deployed in industrial gateways requiring real-time connectivity and deterministic I/O control.

For engineers reviewing the STM32F407VGT6TR datasheet, STM32F407VGT6TR pinout, STM32F407VGT6TR application, or STM32F407VGT6TR equivalent, key selection criteria include Ethernet MAC timing compliance, dual-CAN bus arbitration latency, ART Accelerator-enabled zero-wait-state flash execution at 168 MHz, and 140 GPIOs with 5 V tolerance for mixed-voltage system interfacing.

Technical Context

The STM32F407VGT6TR integrates an Arm Cortex-M4 core with hardware FPU and Adaptive Real-Time (ART) Accelerator enabling deterministic 168 MHz execution from flash memory without wait states. Its multi-AHB bus matrix concurrently services CPU, DMA, and peripheral accesses, supporting high-throughput data movement between Ethernet MAC, DCMI, and SDIO interfaces.

It implements dual independent clock domains (APB1 @ 42 MHz, APB2 @ 84 MHz) with dedicated prescalers, enabling precise timer synchronization across 17 timers - including two 32-bit general-purpose timers with quadrature encoder input and four-channel PWM output - critical for motor control and industrial PLC timing.

FAQ

What is the maximum operating temperature range for STM32F407VGT6TR?

The STM32F407VGT6TR is rated for industrial temperature range: –40 °C to +85 °C ambient. Thermal characteristics in DS8626 Rev 12 specify junction-to-ambient thermal resistance (R_θJA) of 34.2 °C/W for LQFP100, requiring minimum 2-layer PCB with thermal vias under the exposed pad for sustained 168 MHz operation at +85 °C.

Does STM32F407VGT6TR support USB device, host, and OTG simultaneously?

No - the STM32F407VGT6TR integrates two independent USB controllers: one full-speed (FS) and one high-speed/full-speed (HS/FS) OTG. Only one can operate in device or host mode at a time; simultaneous dual-role operation is not supported. The FS controller lacks ULPI interface, while the HS/FS controller includes ULPI and dedicated DMA.

How many independent CAN buses does STM32F407VGT6TR support?

The STM32F407VGT6TR supports two fully independent CAN 2.0B controllers (bxCAN1 and bxCAN2), each with its own message RAM, filter banks, and dedicated APB1 clock domain. They operate concurrently without resource contention, enabling dual-bus applications like chassis diagnostics and powertrain monitoring.

Is the 64 KB CCM SRAM accessible by DMA?

No - the 64 KB Core Coupled Memory (CCM) SRAM is accessible exclusively by the Cortex-M4 CPU and cannot be addressed by DMA controllers. This architectural restriction ensures deterministic ISR execution and prevents DMA-induced memory contention, making CCM ideal for critical stack storage or real-time algorithm variables.
