Product details
Overview
STM32F207IFH6TR from STMicroelectronics is a 32-bit Arm® Cortex®-M3 microcontroller with 1 MB Flash, 128 + 4 KB SRAM, dual CAN 2.0B interfaces, 10/100 Ethernet MAC with IEEE 1588v2 hardware support, and USB 2.0 HS/FS OTG controllers - deployed in industrial gateways requiring real-time protocol bridging, secure firmware updates, and deterministic network timing.
For engineers reviewing the STM32F207IFH6TR datasheet, STM32F207IFH6TR pinout, STM32F207IFH6TR application, or STM32F207IFH6TR equivalent, key selection criteria include Ethernet MAC DMA coherency, dual-CAN arbitration latency, ART Accelerator™-enabled zero-wait-state Flash execution at 120 MHz, and 140 I/Os with 5 V tolerance for mixed-voltage system interfacing.
Technical Context
The device integrates a multi-AHB bus matrix enabling concurrent access to Flash, SRAM, and peripherals without contention; its Ethernet MAC supports MII/RMII physical layer interfaces and hardware timestamping for IEEE 1588v2 precision time protocol (PTP) synchronization in industrial automation networks.
ART Accelerator™ eliminates Flash wait states by caching instruction fetches and branch predictions, while the flexible static memory controller (FSMC) supports NOR/NAND/PSRAM with programmable timing for external display or storage expansion - critical for HMI and edge data logging applications.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F407IGT6 | Higher clock (168 MHz), FPU, no Ethernet MAC hardware timestamping, same LQFP176 package | Lacks IEEE 1588v2 support; requires software timestamping for PTP - unsuitable for sub-1 µs synchronization | Select when floating-point math dominates over deterministic network timing. |
| STM32H743ZIT6 | Cortex-M7 core, dual-core option, 1 MB Flash, 1 MB SRAM, enhanced Ethernet with TSN support | TSN-capable but higher power and cost; overqualified for basic EtherNet/IP or PROFINET IRT Class A | Select only if Time-Sensitive Networking features (gate control, frame preemption) are mandatory. |
Compared with STM32F207IFH6TR, the STM32F407IGT6 trades IEEE 1588v2 hardware timestamping for FPU performance, while the STM32H743ZIT6 adds TSN readiness at significantly higher cost and power - making the F207 optimal for cost-constrained, precision-timing industrial gateways.

FAQ
What is the maximum operating frequency and how is it achieved?
The STM32F207IFH6TR achieves 120 MHz maximum CPU frequency using the internal PLL driven by the HSE (4–26 MHz crystal) or HSI (16 MHz RC). The ART Accelerator™ enables zero-wait-state execution from Flash memory at this speed, verified per DS6329 Rev 18 Section 3.2. This eliminates instruction fetch stalls and guarantees consistent interrupt latency for real-time control loops.
Does this MCU support hardware-based IEEE 1588v2 timestamping?
Yes - the integrated 10/100 Ethernet MAC includes dedicated hardware timestamping logic compliant with IEEE 1588v2 Annex D. It captures precise transmit/receive timestamps at the MAC layer with sub-microsecond resolution, independent of CPU load. This is confirmed in DS6329 Rev 18 Section 3.26 and Electrical Characteristics Table 6.3.26.
How many CAN interfaces does the STM32F207IFH6TR provide, and are they electrically isolated?
The device integrates two fully independent CAN 2.0B controllers (CAN1 and CAN2), each with dedicated message RAM, filters, and FIFOs. Neither interface includes galvanic isolation; external isolated transceivers (e.g., ISO1050) must be used for bus-level isolation. Pin assignments are PA12/PA11 (CAN1) and PD0/PD1 (CAN2), per DS6329 Rev 18 Pin Definitions Table 8.
What package type and pin count does STM32F207IFH6TR use?
STM32F207IFH6TR uses the LQFP176 package: 176-pin, 24 × 24 mm body, 0.5 mm pitch, with exposed thermal pad (EPAD) for enhanced thermal dissipation. This matches the 'H' suffix in the part number and is documented in DS6329 Rev 18 Section 7.5 and Table 1. It operates across the industrial temperature range (–40°C to +105°C).
