Product details

Overview

STM32F407IGH7 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 Ethernet timing.

For engineers reviewing the STM32F407IGH7 datasheet, STM32F407IGH7 pinout, STM32F407IGH7 application, or STM32F407IGH7 equivalent, key selection criteria include Ethernet MAC + IEEE 1588v2 hardware timestamping capability, dual-CAN bus coexistence, camera interface (DCMI) bandwidth up to 54 MB/s, and CCM RAM for time-critical ISR execution without cache latency.

Technical Context

The device integrates an Adaptive Real-time Accelerator (ART Accelerator) enabling zero-wait-state execution from flash at 168 MHz, paired with a memory protection unit (MPU) for secure task isolation. Its multi-AHB bus matrix concurrently services CPU, DMA, and peripheral accesses without arbitration stalls.

It implements dual USB PHYs - one full-speed on-chip PHY for OTG_FS and one high-speed PHY with ULPI interface plus dedicated DMA for OTG_HS - alongside a fully featured 10/100 Ethernet MAC supporting MII/RMII, IEEE 1588v2 hardware timestamping, and integrated DMA for low-CPU-load packet processing.

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; delivers 210 DMIPS and deterministic interrupt latency for hard real-time tasks.
Flash / RAM	1 MB flash + 192 KB SRAM + 4 KB backup SRAM + 64 KB CCM RAM; CCM allows critical code/data placement for zero-latency access by CPU core.
Ethernet Interface	10/100 MAC with IEEE 1588v2 hardware timestamping; supports precise time-synchronized industrial networking (e.g., TSN-aware gateways).
USB Support	Dual controllers: OTG_FS (on-chip FS PHY) and OTG_HS (dedicated DMA + on-chip FS PHY + ULPI for HS); enables simultaneous host/device roles with minimal firmware overhead.
Camera Interface	8–14-bit parallel DCMI supporting up to 54 MB/s; directly interfaces CMOS image sensors for embedded vision without external FIFO buffering.
Analog Peripherals	Three 12-bit ADCs (2.4 MSPS each, 7.2 MSPS triple interleaved) + two 12-bit DACs; supports multichannel sensor acquisition and waveform generation in test equipment.

Pinout & Package

STM32F407IGH7 uses a UFBGA176 package (10 × 10 mm, 0.8 mm pitch) with 176 I/O terminals, including dedicated Ethernet MII/RMII pins, dual CANH/CANL pairs, DCMI data/control lines, and dual USB ULPI/FS PHY signal groups.

Pin/Terminal	Circuit Role	Design Meaning
PA0–PA15, PB0–PB15, etc.	General-purpose I/O with multiple alternate functions	Configurable as GPIO, UART TX/RX, SPI SCK/MOSI/MISO, I2C SCL/SDA, or timer channels - enabling flexible peripheral routing on PCB.
PH13–PH15, PI0–PI10	Ethernet MII interface signals	Direct connection to external PHY chip (e.g., LAN8720A) without level-shifting; supports both MII and RMII modes via software configuration.
PD0–PD7, PD8–PD15	DCMI data bus (D0–D15)	16-bit parallel pixel data path synchronized to HSYNC/VSYNC/PCLK; supports 720p30 capture with DMA offload to SRAM.
PA11/PA12, PB14/PB15	USB OTG_FS and OTG_HS physical layer signals	PA11/PA12 = FS D+/D− with integrated transceiver; PB14/PB15 = ULPI clock/data for HS PHY - no external USB PHY required for FS, optional for HS.
PB8/PB9, PD0/PD1	CAN1/CAN2 TX/RX	Dual independent CAN controllers with separate TX/RX pins; enables redundant fieldbus communication or gateway bridging between two CAN networks.

Key Features

Feature	Design Value
ART Accelerator	Enables 0-wait-state execution from flash at 168 MHz - eliminates instruction fetch stalls and ensures consistent real-time response.
CCM RAM	64 KB tightly coupled memory accessible only by CPU core - ideal for ISRs, stack, or critical variables needing deterministic access time.
IEEE 1588v2 Hardware Timestamping	Embedded timestamp logic in Ethernet MAC captures PTP event message timestamps at wire-level precision (<100 ns resolution).
Triple-interleaved ADC Mode	7.2 MSPS aggregate sampling across three 12-bit ADCs - supports high-speed analog monitoring in power quality analyzers.
Dual USB Controllers	OTG_FS + OTG_HS with independent DMA engines - allows concurrent USB device (e.g., CDC ACM) and host (e.g., mass storage) operation without CPU contention.

Equivalent & Alternatives

The following parts are listed as comparable options for similar microcontroller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice

FAQ

What is the maximum operating temperature range for STM32F407IGH7?

The STM32F407IGH7 is rated for industrial temperature range: –40 °C to +85 °C ambient, validated per ST's qualification standards (AEC-Q100 not applicable; this is an industrial-grade part). Thermal performance is specified with 176-ball UFBGA package and JEDEC-standard PCB layout per DS8626 Section 7.8.

Does STM32F407IGH7 support external memory expansion?

Yes - it integrates a Flexible Static Memory Controller (FSMC) supporting NOR, PSRAM, SRAM, and NAND flash with 8-/16-bit data bus widths and configurable timing. The UFBGA176 package exposes all necessary address/data/control signals (e.g., NE1–NE4, NOE, NWE, A0–A25, D0–D15) for direct connection to external memories up to 64 MB address space.

How many independent CAN interfaces does STM32F407IGH7 provide?

It provides two fully independent bxCAN 2.0B controllers (CAN1 and CAN2), each with its own TX/RX pins, message RAM, and filter banks. Both support bit rates up to 1 Mbps and operate simultaneously - enabling gateway applications that bridge separate CAN networks or implement redundant communication paths.

Is the Ethernet MAC capable of IEEE 1588v2 hardware timestamping?

Yes - the integrated 10/100 Ethernet MAC includes dedicated hardware timestamping logic compliant with IEEE 1588-2008 (v2) Annex D. It captures precise transmit/receive timestamps for PTP event messages at the PHY interface level with sub-100 ns resolution, independent of CPU load or software interrupt latency.
