STMicroelectronics STM32F207IGH6TR

Overview

STM32F207IGH6TR 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 2.0 HS/FS OTG. It serves as a high-integration application processor in industrial gateways requiring real-time connectivity, protocol bridging, and deterministic network timing.

For engineers reviewing the STM32F207IGH6TR datasheet, STM32F207IGH6TR pinout, STM32F207IGH6TR application, or STM32F207IGH6TR equivalent, key selection criteria include Ethernet MAC + IEEE 1588v2 hardware timestamping capability, dual-CAN bus arbitration support, parallel camera interface (DCMI) bandwidth up to 48 MB/s, and ART Accelerator™ enabling zero-wait-state execution from Flash at 120 MHz.

Technical Context

The device integrates a multi-AHB bus matrix for concurrent access to Flash, SRAM, and peripherals, with dedicated DMA channels for Ethernet, USB HS/FS, and DCMI-enabling simultaneous high-bandwidth data paths without CPU intervention. Its clock system includes dual PLLs: main PLL for core/system clocks and audio PLL (PLLI2S) for I2S and DCMI pixel clock generation.

It implements a full-featured memory protection unit (MPU), adaptive real-time accelerator (ART Accelerator™) with prefetch buffer and branch cache, and flexible static memory controller (FSMC) supporting NAND/NOR/PSRAM for external storage expansion. The embedded Ethernet MAC supports MII/RMII physical layer interfaces and hardware-accelerated IEEE 1588v2 timestamping for precision time synchronization.

FAQ

What is the maximum operating frequency and how is it achieved?

The STM32F207IGH6TR achieves 120 MHz maximum CPU frequency using the Arm Cortex-M3 core with Adaptive Real-Time Accelerator (ART Accelerator™). This hardware prefetch and branch cache unit eliminates Flash wait states, enabling zero-wait-state execution from internal 1 MB Flash memory under typical conditions (VDD ≥ 2.7 V).

Does this MCU support hardware-accelerated IEEE 1588 Precision Time Protocol?

Yes. The integrated 10/100 Ethernet MAC includes dedicated IEEE 1588v2 hardware timestamping logic-capable of capturing transmit/receive timestamps with sub-microsecond resolution in hardware, independent of CPU load or interrupt latency. This is confirmed in DS6329 Rev 18 Section 3.26 and Register Reference Manual RM0033.

What camera interfaces does the STM32F207IGH6TR support?

It features an 8–14-bit parallel Digital Camera Interface (DCMI) supporting up to 48 MB/s throughput. The interface synchronizes with the audio PLL (PLLI2S) for precise pixel clock generation and supports ITU-R BT.601/656 standards. DCMI operates independently with dedicated DMA channel, enabling direct frame transfer to SRAM without CPU involvement.

Is the LQFP176 package RoHS-compliant and lead-free?

Yes. The STM32F207IGH6TR in LQFP176 package is manufactured per RoHS Directive 2011/65/EU and uses lead-free matte tin finish on pins. This is documented in ST's official packaging information (DS6329 Rev 18 Section 7.5) and material declaration reports available via ST's Quality & Reliability portal.
