STMicroelectronics STM32F207VGT6TR

Overview

STM32F207VGT6TR from STMicroelectronics is a high-performance Arm® Cortex®-M3 microcontroller featuring 120 MHz CPU frequency, 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 and deterministic network timing.

For engineers reviewing the STM32F207VGT6TR datasheet, STM32F207VGT6TR pinout, STM32F207VGT6TR application, or STM32F207VGT6TR equivalent, key selection criteria include Ethernet MAC + IEEE 1588v2 hardware timestamping capability, dual-CAN bus arbitration support, and parallel camera interface (DCMI) bandwidth up to 48 MB/s for vision-assisted HMI systems.

Technical Context

The STM32F207VGT6TR integrates a Cortex-M3 core with Adaptive Real-Time Accelerator (ART Accelerator™), enabling zero-wait-state execution from Flash at 120 MHz. Its memory subsystem includes 1 MB Flash with ECC, 128 KB main SRAM, and 4 KB backup SRAM powered by VBAT.

It features a multi-AHB bus matrix supporting concurrent access to peripherals including dual CAN controllers, Ethernet MAC with dedicated DMA, USB HS/FS OTG, and DCMI - all synchronized via a flexible clock tree with multiple PLLs (main PLL, audio PLL, and USB PLL).

FAQ

Does STM32F207VGT6TR support IEEE 1588v2 hardware timestamping?

Yes. The integrated 10/100 Ethernet MAC includes dedicated hardware timestamping registers compliant with IEEE 1588v2 Annex D, enabling sub-microsecond precision for PTP event messages. This feature operates independently of CPU load and requires no software overhead for timestamp insertion or extraction.

What is the maximum data rate supported by the DCMI interface?

The DCMI supports up to 48 MB/s in 14-bit parallel mode with pixel clock up to 24 MHz. Verified operation includes OV5640 (5 MP) at 640×480@30 fps in YUV422 format, with synchronous capture controlled via DMA and hardware frame synchronization signals (VSYNC/HSYNC).

Can both CAN interfaces operate simultaneously with independent message filtering?

Yes. Each CAN peripheral (CAN1 and CAN2) has its own set of 14 32-bit filter banks, allowing independent configuration for standard/extended ID filtering, mask mode, and list mode. Both controllers support concurrent transmission/reception without arbitration interference.

Is the ART Accelerator™ enabled by default after reset?

Yes. The ART Accelerator™ is enabled by default upon exit from reset and remains active unless explicitly disabled via SYSCFG register. It automatically manages prefetch and branch cache for Flash accesses, delivering zero-wait-state performance at 120 MHz without user intervention.
