Product details
Overview
STM32F207VCT6 from STMicroelectronics is a 32-bit Arm® Cortex®-M3 microcontroller operating at up to 120 MHz, featuring 256 KB Flash, 64+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 real-time protocol bridging and deterministic network timing.
For engineers reviewing the STM32F207VCT6 datasheet, STM32F207VCT6 pinout, STM32F207VCT6 application, or STM32F207VCT6 equivalent, key selection criteria include Ethernet MAC + IEEE 1588v2 hardware timestamping capability, dual-CAN bus arbitration support, and parallel camera interface (DCMI) timing compliance at 48 MB/s.
Technical Context
The device integrates a multi-AHB bus matrix enabling concurrent access to Flash, SRAM, and peripherals, with dedicated DMA channels for Ethernet (10/100 MAC), USB OTG HS (with ULPI), and DCMI. Its ART Accelerator™ eliminates Flash wait states at 120 MHz, sustaining 150 DMIPS performance.
Clock architecture includes three PLLs: main PLL (up to 120 MHz), audio PLL (PLLI2S) for I2S clock generation, and dedicated USB OTG HS PLL; RTC features 32 kHz crystal oscillator with calibration and VBAT-backed 20×32-bit registers plus optional 4 KB backup SRAM.
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 | Higher clock (168 MHz), larger Flash (1 MB), FPU, but no IEEE 1588v2 hardware timestamping or dual CAN; uses same LQFP100 package. | Lacks hardware PTP support - requires software timestamping (±1–2 µs jitter), unsuitable for sub-microsecond TSN synchronization. | Select when floating-point math or higher instruction throughput is prioritized over deterministic Ethernet timing. |
| STM32H743VIT6 | Cortex-M7 core (480 MHz), dual-core option, 2 MB Flash, Ethernet with IEEE 1588v2, but no DCMI interface; LQFP100 package with different pinout. | Missing parallel camera interface - cannot replace STM32F207VCT6 in DCMI-dependent vision applications without redesign. | Choose for next-gen designs needing higher compute density and future-proof Ethernet features, accepting DCMI removal and board layout change. |
Compared with STM32F407VGT6, STM32F207VCT6 provides deterministic IEEE 1588v2 hardware timestamping essential for industrial Ethernet, while STM32H743VIT6 trades DCMI for higher performance and dual-core flexibility - making STM32F207VCT6 optimal for cost-constrained, camera + Ethernet co-integration use cases.

FAQ
What is the maximum operating frequency and how is it achieved?
The STM32F207VCT6 achieves 120 MHz maximum CPU frequency using its internal main PLL driven by the HSE (4–26 MHz crystal) or HSI (16 MHz RC). The ART Accelerator™ eliminates Flash wait states at this speed, enabling sustained 150 DMIPS performance with zero-cycle instruction fetch latency from internal Flash memory.
Does STM32F207VCT6 support hardware-accelerated 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 PHY boundary with sub-100 ns resolution, independent of CPU load, enabling accurate master clock synchronization in industrial TSN networks.
What camera interfaces does STM32F207VCT6 support and what is the maximum data rate?
The device features an 8- to 14-bit parallel Digital Camera Interface (DCMI) supporting up to 48 MB/s throughput. In 8-bit mode with PIXCLK at 48 MHz, it captures VGA (640×480) at 30 fps with full DMA offload - no CPU involvement required for pixel buffering or frame transfer to SRAM.
How many CAN interfaces are integrated and what protocol versions do they support?
STM32F207VCT6 integrates two independent CAN 2.0B controllers supporting both standard (11-bit) and extended (29-bit) identifier frames. While the hardware is compatible with CAN FD physical layer signaling, the firmware driver stack and reference designs provided by ST are limited to CAN 2.0B operation per ISO 11898-1:2015.
