Product details
Overview
STM32F207IFT6 from STMicroelectronics is a 32-bit Arm® Cortex®-M3 microcontroller operating at up to 120 MHz, featuring 1 MB Flash, 128+4 KB SRAM, 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 deterministic real-time networking and multi-protocol connectivity.
For engineers reviewing the STM32F207IFT6 datasheet, STM32F207IFT6 pinout, STM32F207IFT6 application, or STM32F207IFT6 equivalent, key selection criteria include Ethernet MAC timing compliance, dual-CAN arbitration latency, ART Accelerator™-enabled Flash execution performance, and LQFP100 package I/O count with 5 V-tolerant capability.
Technical Context
The device integrates a dual-bus AHB matrix enabling concurrent access to Flash, SRAM, and peripherals - critical for simultaneous Ethernet packet buffering, CAN message queuing, and camera interface streaming. Its ART Accelerator™ eliminates Flash wait states at 120 MHz, delivering 150 DMIPS sustained performance without external cache.
Hardware-accelerated IEEE 1588v2 timestamping operates independently of CPU load, while dedicated DMA channels serve Ethernet (2x), USB OTG HS (2x), and DCMI (1x) - ensuring deterministic latency for time-sensitive industrial protocols.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F407VGT6 | Higher clock (168 MHz), FPU, no IEEE 1588v2 hardware support, same LQFP100 pinout but different ETH/DCMI pin mapping. | Lacks hardware timestamping - requires software timestamping with higher jitter (>1 µs) unsuitable for precision motion control. | Select when floating-point math dominates over deterministic Ethernet timing. |
| STM32H743VIT6 | Cortex-M7 core (480 MHz), dual-core option, 2 MB Flash, supports TSN via Ethernet AVB extensions, incompatible pinout. | Requires PCB redesign; adds complexity for TSN but unnecessary for standard 1588v2 deployments. | Choose only when migrating to Time-Sensitive Networking with AVB/TSN bridges. |
Compared with STM32F407VGT6, STM32F207IFT6 delivers lower-jitter IEEE 1588v2 timestamping and dual-CAN arbitration without FPU overhead; versus STM32H743VIT6, it offers pin-compatible upgrade path from legacy F2 designs while retaining proven industrial Ethernet drivers and HAL support.

FAQ
What is the maximum operating temperature range for STM32F207IFT6?
The STM32F207IFT6 is rated for industrial temperature range: –40°C to +85°C ambient. Its internal temperature sensor (±1.5°C accuracy) and voltage regulator stability across this range ensure reliable operation in unventilated control cabinets and outdoor metering enclosures without thermal throttling.
Does STM32F207IFT6 support USB OTG Host mode with mass storage class?
Yes - the integrated USB OTG HS controller supports full-speed and high-speed host mode with class-compliant Mass Storage Class (MSC) driver support in STM32CubeF2 middleware. It enumerates USB flash drives and SD card readers without external PHY, leveraging the on-chip ULPI interface for HS operation.
How many Ethernet MAC clock sources are supported, and what are their frequencies?
The Ethernet MAC supports two clock sources: RMII mode uses a 50 MHz external crystal or oscillator; MII mode requires a 25 MHz source. Both are routed through the AHB bus matrix and synchronized to the APB1 domain - enabling precise PTP timestamp alignment independent of system clock scaling.
Can the FSMC interface be used simultaneously with the DCMI camera interface?
No - FSMC and DCMI share overlapping GPIO resources (e.g., PD0–PD15) and cannot operate concurrently. The reference manual specifies mutual exclusion: enabling DCMI disables FSMC address/data multiplexing, and vice versa - requiring hardware partitioning in PCB layout for dual-function designs.
