Product details
Overview
STM32F207IGH6J 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-connectivity application processor in industrial gateways requiring real-time networking, fieldbus coexistence, and deterministic communication.
For engineers reviewing the STM32F207IGH6J datasheet, STM32F207IGH6J pinout, STM32F207IGH6J application, or STM32F207IGH6J equivalent, key selection considerations include Ethernet MAC timing compliance, dual-CAN arbitration latency, ULPI interface signal integrity, and VBAT-backed RTC + 4 KB backup SRAM retention under brownout conditions.
Technical Context
The device integrates a multi-AHB bus matrix enabling concurrent access to Flash, SRAM, and peripherals without contention; its ART Accelerator™ eliminates Flash wait states at 120 MHz, delivering 150 DMIPS (1.25 DMIPS/MHz). The embedded Ethernet MAC includes dedicated DMA, MII/RMII PHY interface, and hardware timestamping for IEEE 1588v2 precision time protocol.
It supports triple-interleaved ADC sampling at up to 6 MSPS across 24 channels, two 12-bit DACs, and a parallel 8–14-bit DCMI interface capable of 48 MB/s camera data capture. Clock management includes dual PLLs - main PLL for CPU/system clocks and audio PLL (PLLI2S) for I2S synchronization - with factory-trimmed 16 MHz HSI and 32 kHz LSE for RTC calibration.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-connectivity MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F407IGT6 | Higher CPU frequency (168 MHz), FPU, but no IEEE 1588v2 hardware timestamping; Ethernet MAC lacks MII/RMII dual-mode support. | Suitable for floating-point intensive tasks (e.g., sensor fusion), but requires software PTP stack with higher jitter. | Select when computational throughput outweighs deterministic Ethernet timing needs. |
| STM32H743ZIT6 | Cortex-M7 core (480 MHz), dual-core option, TSN-capable Ethernet, but no native ULPI interface; requires external USB HS PHY with PCIe-like SerDes complexity. | Targeted at time-sensitive networking (TSN) and AI edge inference; higher BOM cost and PCB layer count. | Select only when migrating to TSN standards or requiring >200 DMIPS real-time processing. |
Compared with STM32F407IGT6, STM32F207IGH6J delivers superior deterministic Ethernet performance via hardware IEEE 1588v2 support and RMII flexibility, while STM32H743ZIT6 trades off USB HS simplicity for TSN readiness - making the F207 optimal for cost-sensitive industrial gateways needing proven, low-risk 10/100 Ethernet + dual CAN integration.

FAQ
What is the maximum operating temperature range for STM32F207IGH6J?
The STM32F207IGH6J is rated for industrial temperature range: –40 °C to +105 °C ambient. This is validated per JEDEC JESD22-A104 for storage and JESD22-A108 for operating life, with thermal derating applied above 85 °C ambient when using the LQFP176 EPAD for heatsinking.
Does STM32F207IGH6J support hardware encryption acceleration?
No, the STM32F207IGH6J does not include a cryptographic accelerator. It relies on software libraries (e.g., STM32Cube HAL with AES-128 CBC mode) for encryption. For hardware crypto, consider STM32F415xx or STM32L4+ series with CRYP/Hash peripherals.
Can the USB HS interface operate without an external PHY?
No - USB HS requires an external ULPI-compliant PHY (e.g., SMSC USB3300 or Microchip USB5744). The STM32F207IGH6J provides only the ULPI interface (60 MHz clock + 8-bit bidirectional data bus); on-chip transceivers are limited to USB FS mode.
How is the 4 KB backup SRAM enabled and retained?
The 4 KB backup SRAM is enabled via PWR_CR.BRSD bit and powered by VBAT. It retains data during main power loss if VBAT ≥ 1.8 V and the BKP domain is unreset. Access requires unlocking the backup domain with PWR_CR.DBP = 1 and enabling the BKP clock in RCC_BDCR.
