Product details
Overview
STM32F407IGT7 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 and deterministic I/O control.
For engineers reviewing the STM32F407IGT7 datasheet, STM32F407IGT7 pinout, STM32F407IGT7 application, or STM32F407IGT7 equivalent, key selection criteria include Ethernet MAC timing compliance, dual-CAN bus arbitration latency, DCMI interface bandwidth (up to 54 MB/s), ART Accelerator-enabled zero-wait-state flash execution, and CCM RAM allocation for time-critical ISR stacks.
Technical Context
The STM32F407IGT7 integrates an Adaptive Real-time Accelerator (ART) enabling deterministic 0-wait-state execution from flash 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 implements dual-domain clocking: APB1 (42 MHz) for low-speed peripherals (I²C, USART, CAN), APB2 (84 MHz) for high-speed I/O (GPIO, ADC, TIM), and AHB (168 MHz) for core, memory, and high-bandwidth interfaces (Ethernet, USB OTG HS, SDIO). The dedicated Ethernet DMA supports scatter-gather descriptors and checksum offload.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M4 with FPU and DSP instructions; enables floating-point math for motor control and audio processing without software emulation. |
| Max Clock Frequency | 168 MHz with ART Accelerator; guarantees cycle-accurate timing for servo loop execution ≤ 6 µs. |
| Flash / SRAM | 1 MB flash + 192 KB SRAM + 4 KB backup SRAM + 64 KB CCM; CCM supports zero-latency stack access for critical ISRs. |
| Ethernet Interface | 10/100 MAC with IEEE 1588v2 hardware timestamping; enables sub-microsecond packet timestamping for industrial time-sensitive networking (TSN). |
| USB Support | OTG HS (480 Mbps) + OTG FS (12 Mbps) with dedicated DMA; allows simultaneous host/device roles and isochronous audio streaming. |
| Analog Peripherals | Three 12-bit ADCs (2.4 MSPS each, 7.2 MSPS interleaved); supports synchronized sampling across three phases in PMSM motor control. |
| Camera Interface | 8–14-bit parallel DCMI supporting 54 MB/s throughput; enables direct connection to OV5640 or similar CMOS sensors without external FIFO buffering. |
Pinout & Package
LQFP176 (24 × 24 mm, 0.5 mm pitch) package with 140 general-purpose I/Os - 136 rated for 84 MHz operation and 138 tolerant to 5 V on input-only pins. Includes dedicated VCAP_1/VCAP_2 pins for internal regulator decoupling and NRST with Schmitt-trigger input for robust reset assertion.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| PG13 | ETH_TXD0 | Dedicated MII/RMII Ethernet transmit data line; requires impedance-controlled PCB routing (50 Ω single-ended) for 100BASE-TX compliance. |
| PC1 | ETH_MDC | Management Data Clock for PHY register access; operates at ≤ 2.5 MHz and must be routed away from high-speed digital traces. |
| VCAP_1 / VCAP_2 | Internal voltage regulator bypass | Require 2.2 µF X5R ceramic capacitors placed within 2 mm of respective pins to stabilize core voltage during dynamic load transitions. |
Key Features
| Feature | Design Value |
|---|---|
| ART Accelerator | Eliminates flash wait states at 168 MHz, reducing instruction fetch latency to match SRAM performance - critical for hard real-time control loops. |
| CCM RAM | 64 KB tightly coupled memory accessible only by CPU (not DMA); used for ISR stacks and low-latency variables without bus arbitration delay. |
| Dual CAN Controllers | Independent CAN 2.0B modules with programmable bit timing, TX mailbox prioritization, and automatic retransmission - supports redundant fieldbus communication. |
| IEEE 1588v2 Hardware Timestamping | Dedicated registers capture precise ingress/egress timestamps on Ethernet frames at hardware level, enabling sub-100 ns synchronization accuracy. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-performance MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32H743VIT6 | Arm Cortex-M7 @ 480 MHz, 2 MB flash, dual-core capability, no DCMI, higher power consumption | Better for AI inference offload but lacks native camera interface; requires external image buffer | Select when >300 DMIPS and dual-core RTOS partitioning are required, and camera interface is handled externally. |
| STM32F429ZIT6 | Same Cortex-M4 core, identical pinout, adds LCD-TFT controller and Chrom-ART accelerator, same Ethernet/USB/DCMI | Direct drop-in replacement with enhanced graphics capability; same thermal profile and BOM footprint | Choose when embedded GUI rendering (e.g., Qt Quick or emWin) is needed alongside existing STM32F407IGT7 functionality. |
Compared with STM32F407IGT7, the STM32F429ZIT6 offers identical real-time control and connectivity features plus integrated display engine - ideal for HMI-integrated gateways - while the STM32H743VIT6 trades camera support for raw compute headroom, better suited for edge ML where vision preprocessing occurs upstream.

FAQ
What is the maximum ambient temperature rating for continuous operation of STM32F407IGT7 in LQFP176 package?
The STM32F407IGT7 in LQFP176 package has a specified operating ambient temperature range of –40 °C to +85 °C. At maximum junction temperature (105 °C), thermal resistance θJA is 25.2 °C/W; sustained operation above 85 °C ambient requires forced airflow or PCB copper pour to maintain junction temperature below limit.
Does STM32F407IGT7 support hardware encryption acceleration such as AES or SHA?
No, the STM32F407IGT7 does not include dedicated hardware crypto accelerators for AES, SHA, or RSA. It relies on software libraries (e.g., mbed TLS) executed on the Cortex-M4 core. For hardware-accelerated cryptography, ST recommends STM32L4+, STM32H7, or STM32WB series MCUs with CryptoCell or HASH/AES peripherals.
Can the Ethernet MAC operate in RMII mode with external PHY, and what are the critical layout requirements?
Yes, the STM32F407IGT7 supports both MII and RMII modes. In RMII, REF_CLK (50 MHz) must be sourced from external PHY or oscillator, and all RMII signals (TXD0/1, RXD0/1, CRS_DV, TX_EN, REF_CLK) require controlled-impedance routing (50 Ω ±10%), length matching within 250 mils, and separation from noisy digital traces to meet IEEE 802.3u timing margins.
How many independent PWM channels can be generated simultaneously using advanced timers on STM32F407IGT7?
The STM32F407IGT7 includes two advanced-control timers (TIM1 and TIM8), each supporting six PWM outputs (CH1–CH6) with complementary pairs, dead-time insertion, and break input. Combined, they provide up to 12 independent, phase-shifted PWM channels - sufficient for three-phase dual-motor FOC control with redundancy.
