Product details
Overview
STM32F407IEH6TR from STMicroelectronics is a high-performance Arm® Cortex®-M4 32-bit microcontroller with FPU, operating up to 168 MHz (210 DMIPS), featuring 512 KB flash memory, 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 STM32F407IEH6TR datasheet, STM32F407IEH6TR pinout, STM32F407IEH6TR application, or STM32F407IEH6TR equivalent, key selection criteria include Ethernet MAC + IEEE 1588v2 hardware timestamping capability, triple 12-bit ADCs (7.2 MSPS interleaved), camera interface (DCMI) bandwidth up to 54 MB/s, and 138 5 V-tolerant I/Os for mixed-voltage system interfacing.
Technical Context
The STM32F407IEH6TR integrates an Adaptive Real-Time (ART) Accelerator enabling zero-wait-state execution from flash at 168 MHz, alongside a multi-AHB bus matrix for concurrent peripheral access. Its memory subsystem includes 64 KB core-coupled memory (CCM) for time-critical code/data and 512 KB of embedded flash with ECC and 20-year data retention.
It implements dual USB OTG controllers - one full-speed with on-chip PHY, one high-speed with dedicated DMA and ULPI support - plus a 10/100 Ethernet MAC with MII/RMII physical layer interface, hardware-accelerated IEEE 1588v2 timestamping, and integrated DMA for deterministic packet handling without CPU intervention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-performance ARM Cortex-M4 microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F407VGT6 | LQFP100 package (100 pins); 1 MB flash, same peripherals but fewer GPIOs (82 vs. 140) and no DCMI | Suitable for space-constrained designs where Ethernet + USB FS suffices, but lacks camera interface and 5 V-tolerant I/O count | Select when board area is limited and DCMI/5 V-tolerance are not required; verify pin compatibility for existing LQFP100 footprints |
| STM32F767ZIT6 | Cortex-M7 core @ 216 MHz; 2 MB flash, 512 KB RAM; adds FMC, Chrom-ART accelerator, and crypto/hash accelerators | Better suited for GUI-rich HMIs or cryptographic gateway functions; higher power and cost; no native IEEE 1588v2 hardware support | Choose for applications needing >200 MHz compute headroom or hardware crypto, but accept trade-offs in power, cost, and missing 1588v2 timestamping logic |
Compared with STM32F407VGT6, the STM32F407IEH6TR provides 40+ additional GPIOs, DCMI, and 5 V-tolerant I/Os essential for sensor aggregation; versus STM32F767ZIT6, it delivers deterministic IEEE 1588v2 timestamping at lower power and cost - critical for time-sensitive industrial networking.

FAQ
What is the maximum operating temperature range for STM32F407IEH6TR?
The STM32F407IEH6TR is rated for industrial temperature range: –40 °C to +85 °C ambient, validated per JEDEC JESD22-A104. Thermal derating begins above 70 °C ambient when operating at 168 MHz with Ethernet and USB HS active; PCB layout must include thermal vias under the exposed pad for sustained performance.
Does STM32F407IEH6TR support hardware encryption acceleration?
No - the STM32F407IEH6TR does not include dedicated AES, DES, or SHA hardware accelerators. It relies on software libraries (e.g., mbed TLS) for cryptographic operations. For hardware-accelerated crypto, consider STM32F417x or STM32F7xx families, which integrate Crypto Processor (CRYP) and Hash modules.
Can the Ethernet MAC operate without an external PHY?
No - the STM32F407IEH6TR integrates only the Media Access Control (MAC) layer. An external PHY (e.g., LAN8720A or DP83848) is required for physical layer signaling (10/100BASE-TX). The RMII interface uses five signals (REF_CLK, CRS_DV, RXD0/1, TX_EN, TXD0/1) and supports both MII and RMII modes via configuration bits.
How many independent PWM outputs can be generated simultaneously?
The STM32F407IEH6TR supports up to 36 independent PWM outputs: twelve 16-bit timers (TIM2–TIM5, TIM9–TIM14) and two 32-bit timers (TIM1/TIM8), each offering up to four complementary PWM channels with dead-time insertion - sufficient for three-phase motor control, LED dimming, and digital power supply regulation concurrently.
