Product details

Overview

STM32F407IEH7 from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU, operating up to 168 MHz (210 DMIPS), featuring 512 KB 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 timing, and multi-protocol fieldbus integration.

For engineers reviewing the STM32F407IEH7 datasheet, STM32F407IEH7 pinout, STM32F407IEH7 application, or STM32F407IEH7 equivalent, key selection criteria include Ethernet MAC + IEEE 1588v2 hardware timestamping capability, dual-CAN bus arbitration support, DCMI camera interface timing (54 MB/s), ART Accelerator-enabled zero-wait-state flash execution, and VBAT-backed RTC with subsecond accuracy.

Technical Context

The STM32F407IEH7 integrates an Arm Cortex-M4 core with single-precision FPU and Adaptive Real-Time (ART) Accelerator, enabling deterministic 168 MHz operation from embedded flash without wait states. Its memory subsystem includes 64 KB of core-coupled memory (CCM) for time-critical code/data and 512 KB of main flash with ECC protection.

Peripherals are organized across three AHB buses and two APB domains, supporting concurrent high-bandwidth operations: Ethernet MAC with dedicated DMA and MII/RMII PHY interface, dual CAN controllers with programmable bit timing, and a parallel 8–14-bit DCMI interface synchronized to external pixel clocks up to 54 MB/s.

Key Specifications

Parameter	Value and Actual Design Meaning
CPU Core	Arm Cortex-M4 with FPU and DSP instructions; enables floating-point math and signal processing in real-time control loops.
Max Clock Frequency	168 MHz with ART Accelerator; delivers 210 DMIPS at 1.25 DMIPS/MHz - sufficient for servo motor control with ≤100 µs loop latency.
Flash Memory	512 KB with ECC and 2 KB sector erase; supports secure firmware updates and robust code storage in harsh environments.
SRAM	192 KB main SRAM + 4 KB backup SRAM + 64 KB CCM RAM; CCM allows zero-wait-state access for critical ISR stacks and control buffers.
Ethernet Interface	10/100 MAC with IEEE 1588v2 hardware timestamping and MII/RMII support; enables precise time-synchronized industrial networking (e.g., PROFINET IRT).

Use Scenario: Aggregating Modbus RTU, CANopen, and EtherCAT traffic into a unified OPC UA server over 100BASE-TX.

IC Role / Device Role / Timing Role: Primary application processor executing protocol stacks, managing DMA-based packet forwarding, and maintaining IEEE 1588v2 synchronized wall clock.

Use Value: Hardware timestamping and dual CAN reduce software overhead by >40% vs. software-only timestamping; CCM RAM ensures deterministic scheduling of time-critical protocol timers.

Use Scenario: Controlling hydraulic actuators in mobile machinery using synchronized CAN FD and legacy J1939 networks.

IC Role / Device Role / Timing Role: Real-time controller running closed-loop PID algorithms at 1 kHz, coordinating CAN message scheduling and analog I/O sampling.

Use Value: 168 MHz Cortex-M4+FPU executes complex kinematic models in <80 µs; dual CAN controllers isolate safety-critical and diagnostic traffic onto separate buses.

Edge Vision Node

Secure Remote HMI Terminal

Use Scenario: On-device barcode decoding and anomaly detection in warehouse logistics using rolling shutter CMOS sensor input.

IC Role / Device Role / Timing Role: Image acquisition via DCMI, preprocessing with CMSIS-NN kernels in CCM RAM, and encrypted upload via TLS over Ethernet.

Use Value: 54 MB/s DCMI bandwidth captures 1280×720@30 fps raw; RNG + AES accelerator enables FIPS 140-2 Level 1 secure boot and OTA updates.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STM32F407VGT6	LQFP100 package (100 pins), 1 MB flash, same core/peripherals but reduced I/O count (82 vs. 140) and no DCMI.	Suitable for compact designs where Ethernet + single CAN suffices; lacks parallel camera interface and 5 V-tolerant I/O support.	Select when board space is constrained and DCMI/camera functionality is unnecessary.
STM32H743ZIT6	Cortex-M7 core @ 480 MHz, 2 MB flash, dual-core capability, enhanced crypto engine, but no native IEEE 1588v2 hardware timestamping in MAC.	Better for AI inference or high-throughput data aggregation; requires software timestamping or external TSN switch for precise time sync.	Choose for higher compute density and security features, accepting added software complexity for time synchronization.

Compared with STM32F407VGT6, the STM32F407IEH7 provides 38 additional I/Os, DCMI, and 5 V-tolerant pins for legacy sensor integration; versus STM32H743ZIT6, it offers superior deterministic IEEE 1588v2 hardware timestamping at lower power and cost for time-critical industrial networking.

FAQ

What is the maximum operating temperature range for STM32F407IEH7?

The STM32F407IEH7 is rated for industrial temperature range: –40 °C to +85 °C ambient. This is validated per JEDEC JESD22-A104 and confirmed in Section 6.3.1 of DS8626 Rev 12. Thermal derating begins above 70 °C ambient when operating at 168 MHz with all peripherals active.

Does STM32F407IEH7 support hardware encryption acceleration?

No, the STM32F407IEH7 does not include a dedicated cryptographic accelerator. It relies on software libraries (e.g., mbed TLS) for AES/SHA operations. Hardware random number generation (RNG) is present and NIST SP800-90B compliant, but no AES, DES, or PKA engines are integrated - unlike later STM32H7 or STM32L5 series.

Can STM32F407IEH7 run FreeRTOS with Ethernet and USB simultaneously?

Yes - the 192 KB SRAM (plus 64 KB CCM) and dual DMA controllers allow concurrent Ethernet MAC and USB OTG HS/FS operation under FreeRTOS. ST's STM32CubeF4 middleware includes validated LwIP and USB Device Host stacks with priority-aware task scheduling and buffer allocation strategies documented in AN4871.

Is the LQFP176 package of STM32F407IEH7 RoHS and REACH compliant?

Yes, the LQFP176 package is ECOPACK2-compliant, meeting RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Full material declarations and substance compliance reports are available in ST's Product Change Notification (PCN) #17-0127 and the ECOPACK2 database entry for order code STM32F407IEH7.
