Product details
Overview
STM32F407IEH6 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 protocol bridging and deterministic network timing.
For engineers reviewing the STM32F407IEH6 datasheet, STM32F407IEH6 pinout, STM32F407IEH6 application, or STM32F407IEH6 equivalent, key selection criteria include Ethernet MAC + IEEE 1588v2 hardware timestamping capability, dual-CAN bus arbitration support, DCMI camera interface bandwidth (up to 54 MB/s), ART Accelerator-enabled zero-wait-state flash execution, and 138 5 V-tolerant I/Os for mixed-voltage system interfacing.
Technical Context
The STM32F407IEH6 integrates an Arm Cortex-M4 core with single-precision FPU and Adaptive Real-Time (ART) Accelerator, enabling deterministic 168 MHz operation from internal flash without wait states. Its multi-AHB bus matrix concurrently services CPU, DMA, and peripheral accesses - critical for simultaneous Ethernet packet processing, CAN message filtering, and high-speed ADC sampling.
It features a dedicated Ethernet MAC with IEEE 1588v2 hardware timestamping logic, MII/RMII PHY interface, and integrated DMA; two bxCAN controllers supporting full CAN 2.0B protocol with programmable bit timing and mailbox-based TX/RX buffering; and a parallel digital camera interface (DCMI) supporting 8–14-bit YUV/RGB formats at up to 54 MB/s for machine vision preprocessing.
Key Specifications

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-pin), 1 MB flash, same core/peripherals but fewer I/Os (82 vs. 138) and no DCMI. | Suitable for compact designs where Ethernet + single CAN suffices; lacks camera interface and 5 V-tolerant I/O count. | Select when board space is constrained and DCMI/camera functionality is unnecessary. |
| STM32H743ZIT6 | Cortex-M7 core @ 480 MHz, 2 MB flash, dual-core option, no native IEEE 1588v2 hardware timestamping in MAC. | Higher compute throughput for AI inference; requires software PTP stack - increases jitter and CPU load vs. STM32F407IEH6's hardware solution. | Choose for compute-intensive tasks where deterministic sub-μs timestamping is secondary to raw MIPS. |
Compared with STM32F407VGT6, the IEH6 offers 36 more 5 V-tolerant I/Os and integrated DCMI - essential for vision-augmented gateways; versus STM32H743ZIT6, it trades peak CPU performance for guaranteed low-jitter IEEE 1588v2 hardware timestamping and lower power at 168 MHz.

FAQ
What is the maximum operating temperature range for STM32F407IEH6?
The STM32F407IEH6 is rated for industrial temperature range: –40 °C to +85 °C ambient. This is validated per ST's DS8626 specification under regulator ON conditions with VDD = 3.3 V and 168 MHz operation. Thermal derating applies above 70 °C ambient when sustained CPU/DMA load exceeds 70%.
Does STM32F407IEH6 support hardware encryption acceleration?
No, the STM32F407IEH6 does not include dedicated cryptographic accelerators (e.g., AES, SHA, PKA). It relies on software libraries for encryption; secure boot and key storage are unsupported. For hardware crypto, ST's STM32L4+, STM32H7, or STM32U5 series are required.
Can the Ethernet MAC operate in RMII mode with external PHY?
Yes - the STM32F407IEH6 Ethernet MAC supports both MII and RMII physical layer interfaces. RMII mode uses 10 pins (REF_CLK, CRS_DV, TX_EN, TXD[1:0], RXD[1:0], RX_ER) and requires a 50 MHz reference clock. External PHYs like LAN8720A or DP83848 are fully compatible with documented timing constraints.
How many independent PWM channels can be generated simultaneously?
The STM32F407IEH6 supports up to 36 independent PWM outputs: 12 timers (TIM1–TIM5, TIM8–TIM11, TIM13–TIM14) provide 4 channels each, with TIM1/TIM8 offering complementary outputs + dead-time insertion. All channels are individually configurable for frequency, duty cycle, and polarity via ARR/CCR registers.
