Product details

Overview

STM32F407IGH6TR 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, 10/100 Ethernet MAC with IEEE 1588v2 hardware support, and USB OTG HS/FS controllers - deployed in industrial gateways requiring real-time connectivity, deterministic control, and multi-protocol edge processing.

For engineers reviewing the STM32F407IGH6TR datasheet, STM32F407IGH6TR pinout, STM32F407IGH6TR application, or STM32F407IGH6TR equivalent, key selection criteria include Ethernet MAC timing compliance, dual-CAN bus arbitration latency, ART Accelerator-enabled zero-wait-state flash execution, and 140-pin LQFP package I/O routing for parallel camera (DCMI) and FSMC-based external memory expansion.

Technical Context

The STM32F407IGH6TR integrates an Arm Cortex-M4 core with floating-point unit and DSP extensions, coupled with ST's Adaptive Real-Time (ART) Accelerator enabling deterministic 0-wait-state execution from flash at 168 MHz. Its memory subsystem includes 1 MB of embedded flash, 192 KB main SRAM, 4 KB backup SRAM, and 64 KB CCM RAM tightly coupled to the CPU for low-latency data access.

Peripheral architecture features a multi-AHB bus matrix supporting concurrent access to Ethernet MAC, USB OTG HS DMA, DCMI, and FSMC; dual CAN controllers with time-triggered communication capability; and a 14-bit parallel camera interface capable of 54 MB/s throughput synchronized to pixel clock inputs - all coordinated via nested vectored interrupt controller (NVIC) with 224 interrupt channels.

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	LQFP100 package (100-pin), 100 GPIOs, no DCMI, reduced FSMC signals - lacks parallel camera interface and full Ethernet MII routing.	Suitable for compact Ethernet nodes without vision requirements; cannot support 8080 LCD or NAND flash expansion.	Select when board space is constrained and DCMI/FSMC are unused; verify pin compatibility for existing LQFP176 layout migration.
NXP MK66FN2M0VLQ18	ARM Cortex-M4 @ 180 MHz, 2 MB flash, no Ethernet MAC, single CAN, no DCMI - adds USB HS but omits IEEE 1588 and dual-CAN redundancy.	Better for USB-centric medical devices; unsuitable for time-synchronized industrial networks requiring hardware PTP.	Choose only if USB high-speed device functionality outweighs Ethernet and dual-CAN needs; requires redesign of PHY interface and clock tree.

Compared with STM32F407VGT6, the IGH6TR provides 40 additional I/Os and full DCMI/FSMC/Ethernet MII support; versus MK66FN2M0VLQ18, it delivers hardware IEEE 1588v2 timestamping and dual-CAN bus arbitration - both critical for deterministic industrial control where protocol coexistence and timing accuracy are non-negotiable.

FAQ

What is the maximum operating temperature range for STM32F407IGH6TR?

The STM32F407IGH6TR is rated for industrial temperature range: –40 °C to +85 °C ambient, verified per JESD22-A108. Thermal derating begins above 70 °C ambient when operating at 168 MHz with all peripherals active; junction temperature must remain below 125 °C under continuous load.

Does STM32F407IGH6TR support hardware encryption acceleration?

No, the STM32F407IGH6TR does not integrate a cryptographic accelerator (AES, SHA, PKA). It relies on software libraries (e.g., Mbed TLS) for encryption; for hardware-accelerated crypto, consider STM32F412 or STM32L4+ series with CryptoCell-310 or AES engines.

Can the Ethernet MAC operate in RMII mode with external PHY?

Yes, the STM32F407IGH6TR supports both MII and RMII physical layer interfaces. RMII mode uses 5 pins (REF_CLK, CRS_DV, RXD0, RXD1, TX_EN, TXD0, TXD1) and requires a 50 MHz reference clock - confirmed in Section 3.28 of DS8626 Rev 12 and validated with LAN8720A and DP83848 PHYs.

Is the 96-bit unique ID accessible via standard debug interface?

Yes, the factory-programmed 96-bit unique ID is readable via SWD/JTAG through the DBGMCU_IDCODE register (address 0xE0042000) and also accessible in firmware via system memory read at 0x1FFF7A10–0x1FFF7A1B - used for secure device binding and license enforcement without external EEPROM.
