Product details

Overview

STM32F207IGH7 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 real-time protocol bridging and deterministic network timing.

For engineers reviewing the STM32F207IGH7 datasheet, STM32F207IGH7 pinout, STM32F207IGH7 application, or STM32F207IGH7 equivalent, key selection considerations include Ethernet MAC timing compliance, dual-CAN bus arbitration latency, DCMI camera interface bandwidth (up to 48 MB/s), and ART Accelerator™-enabled zero-wait-state Flash execution at 120 MHz.

Technical Context

The device integrates a multi-AHB bus matrix enabling concurrent access to Flash, SRAM, and peripherals including Ethernet DMA, USB OTG HS DMA, and DCMI. Its nested vectored interrupt controller (NVIC) supports 84 maskable interrupt channels with programmable priority levels for time-critical industrial control tasks.

Clock architecture includes three PLLs: main PLL for CPU/system clocks, audio PLL (PLLI2S) for I2S synchronization, and dedicated USB OTG HS PLL - all configurable via RCC registers with spread-spectrum clock generation (SSCG) support to reduce EMI in dense PCB layouts.

Equivalent & Alternatives

The following parts are listed as comparable options for similar microcontroller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STM32F407IGT6	Higher CPU frequency (168 MHz), FPU, no Ethernet MAC, single CAN, no DCMI	Better for floating-point math-intensive tasks (motor control), unsuitable for Ethernet gateway or camera interface roles	Select when floating-point performance outweighs Ethernet/CAN/DCMI requirements
STM32H743VIT6	Cortex-M7 core (480 MHz), dual-core option, 2 MB Flash, no DCMI, Ethernet with AVB support	Targeted at high-end HMI and AI edge inference; lacks native camera interface and dual CAN 2.0B compatibility	Choose for advanced graphics or ML workloads where legacy camera or CAN 2.0B integration is not required

Compared with STM32F407IGT6 and STM32H743VIT6, the STM32F207IGH7 uniquely balances deterministic real-time Ethernet/CAN protocol stack execution, hardware-accelerated camera capture, and industrial-grade peripheral integration - making it irreplaceable for cost-constrained, connectivity-dense embedded gateways.

FAQ

What is the maximum operating temperature for STM32F207IGH7 in LQFP176 package?

The STM32F207IGH7 is rated for industrial temperature range (–40°C to +85°C). Thermal characteristics in DS6329 Rev 18 specify junction-to-ambient thermal resistance (R_θJA) of 26.5°C/W for LQFP176, enabling reliable 120 MHz operation at +85°C ambient with standard 2-layer PCB layout and 1 oz copper.

Does STM32F207IGH7 support hardware encryption or secure boot?

No. The STM32F207IGH7 does not integrate hardware cryptographic accelerators (AES, SHA, PKA) or secure boot ROM. Security relies on software-implemented TLS stacks and external secure elements; later STM32F4/F7/H7 families add TRNG and crypto peripherals.

Can the Ethernet MAC operate in RMII mode with internal PHY?

No. The STM32F207IGH7 Ethernet MAC requires an external PHY for both MII and RMII modes. It provides only the MAC layer with dedicated DMA and IEEE 1588v2 timestamping logic - no integrated PHY is present.

How many independent CAN message objects does the dual CAN controller support?

Each CAN controller supports 14 dedicated message objects (mailboxes) with individual acceptance filters and transmit/receive FIFOs. Combined, the dual CAN subsystem manages up to 28 concurrent message buffers - sufficient for CANopen master node or J1939 gateway implementations.
