Product details
Overview
STM32F207IGH6 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 OTG HS/FS controllers - deployed in industrial gateways requiring real-time protocol bridging, deterministic networking, and multi-interface peripheral management.
For engineers reviewing the STM32F207IGH6 datasheet, STM32F207IGH6 pinout, STM32F207IGH6 application, or STM32F207IGH6 equivalent, key selection considerations include Ethernet MAC timing compliance, dual-CAN arbitration latency, OTG HS ULPI interface routing, and 140-pin I/O voltage tolerance (5 V-tolerant on 138 pins) for mixed-signal system integration.
Technical Context
The STM32F207IGH6 integrates a Cortex-M3 core with Adaptive Real-Time Accelerator (ART™) enabling zero-wait-state execution from Flash at 120 MHz. Its memory subsystem includes flexible static memory controller (FSMC) supporting NAND/NOR/PSRAM and parallel LCD interface (8080/6800 modes), plus dedicated DMA channels for Ethernet, USB OTG HS, and camera interface.
Peripheral architecture features dual APB buses (APB1 @ 30 MHz, APB2 @ 60 MHz), multi-AHB bus matrix for concurrent access, and nested vectored interrupt controller (NVIC) with 84 maskable interrupt channels - enabling deterministic response to Ethernet packet arrival, CAN frame reception, and USB SOF events within sub-1 µs latency.
Key Specifications

|---|---|
| CPU Core | Arm Cortex-M3 @ 120 MHz; delivers 150 DMIPS with ART Accelerator enabling deterministic real-time code execution from Flash. |
| Memory | 1 MB Flash + 128 KB SRAM + 4 KB backup SRAM; supports firmware over-the-air (FOTA) updates with dual-bank capability and secure boot partitioning. |
| Ethernet Interface | 10/100 MAC with IEEE 1588v2 hardware timestamping; enables precise time synchronization for industrial Ethernet protocols (e.g., EtherCAT slave, PROFINET IRT). |
| USB Connectivity | Dual USB controllers: OTG FS (on-chip PHY) + OTG HS (ULPI interface + dedicated DMA); allows simultaneous host/device operation and high-bandwidth data streaming (e.g., USB video class). |
| Communication Peripherals | 2× CAN 2.0B, 3× I²C, 4× USART + 2× UART, 3× SPI (30 Mbit/s), SDIO; supports multi-protocol fieldbus gateway design without external bridge ICs. |
| Analog Subsystem | 3× 12-bit ADCs (up to 6 MSPS in triple interleaved mode), 2× 12-bit DACs, temperature sensor; enables closed-loop motor control with synchronized current/voltage sampling. |
| I/O Capability | 140 GPIOs, 138 of which are 5 V-tolerant; simplifies level-shifting in legacy industrial I/O modules interfacing with 5 V sensors and actuators. |
Pinout & Package
LQFP176 (24 × 24 mm, 0.5 mm pitch) package with exposed thermal pad; RoHS-compliant, industrial temperature range (–40°C to +105°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VSS | Core power supply / ground | 1.8–3.6 V main supply; requires separate VCAP1/VCAP2 2.2 µF ceramic decoupling per voltage regulator input. |
| PA0–PA15, PB0–PB15, etc. | General-purpose I/O | 140 total GPIOs; most support multiple alternate functions including Ethernet MII/RMII, CAN TX/RX, USB DP/DM, and FSMC address/data lines. |
| PH13–PH15, PI0–PI10 | Ethernet MAC interface | MII/RMII signals (TXD0–TXD3, RXD0–RXD3, TX_EN, CRS_DV, REF_CLK); RMII mode reduces pin count to 9 pins while maintaining 100 Mbps throughput. |
| PD0–PD15, PE0–PE15 | FSMC bus | Supports NOR/PSRAM/NAND memory mapping; enables external program storage or HMI framebuffer expansion up to 64 MB address space. |
| PA11/PA12, PB14/PB15 | USB OTG FS/HS | PA11/PA12 = FS DP/DM (integrated PHY); PB14/PB15 = HS ULPI clock/data (requires external ULPI transceiver for HS operation). |
| PB8/PB9, PD0/PD1 | CAN1/CAN2 | Dual independent CAN 2.0B controllers; each with dedicated TX/RX pins and programmable bit timing for multi-network diagnostics or redundancy. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-performance MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F407IGT6 | Higher CPU speed (168 MHz), FPU, no Ethernet MAC, single CAN, no IEEE 1588 support | Better for floating-point math-intensive tasks (e.g., FFT-based signal analysis), unsuitable for deterministic Ethernet timing | Select when computational throughput > networking determinism; verify external PHY required for 100 Mbps connectivity. |
| STM32H743ZIT6 | Cortex-M7 @ 480 MHz, dual-core option, Gigabit Ethernet MAC, no DCMI, higher power consumption | Targeted at AI edge inference and high-throughput data aggregation; lacks parallel camera interface needed for vision systems | Choose for future-proof scalability where 100 Mbps Ethernet is insufficient and external DDR3 is acceptable. |
Compared with STM32F207IGH6, the STM32F407IGT6 trades Ethernet determinism for raw compute and FPU capability, while the STM32H743ZIT6 sacrifices DCMI and cost-efficiency for Gigabit throughput and dual-core flexibility - making the F207 optimal for cost-constrained, time-sensitive industrial networking with camera or FSMC expansion.

FAQ
What is the maximum operating temperature rating for STM32F207IGH6?
The STM32F207IGH6 is qualified for industrial temperature range: –40°C to +105°C ambient. This rating is validated per JEDEC JESD22-A104 and applies to all LQFP176 package variants. Thermal derating begins above 85°C ambient when operating at full 120 MHz with all peripherals active; recommended PCB layout includes thermal vias under the exposed pad.
Does STM32F207IGH6 support hardware encryption acceleration?
No, the STM32F207IGH6 does not include dedicated cryptographic accelerators (AES, SHA, PKA). It relies on software libraries (e.g., mbed TLS) running on the Cortex-M3 core. For hardware crypto, consider STM32F413/F423 (AES-TDC) or STM32L4+/H7 series with CryptoCell-310 or AES engines.
Can the Ethernet MAC operate in RMII mode with internal PHY?
No - the STM32F207IGH6 Ethernet MAC requires an external PHY for both MII and RMII modes. The chip provides only the MAC layer; RMII reduces pin count to 9 signals (REF_CLK, CRS_DV, RXD0–RXD1, TX_EN, TXD0–TXD1) but still mandates external PHY (e.g., LAN8720A) for physical layer signaling and auto-negotiation.
Is the 4 KB backup SRAM enabled by default after reset?
No, the 4 KB backup SRAM is disabled by default and must be explicitly enabled via the PWR_CR register (DBP bit set + BKPSRAMEN bit). It remains powered only when VBAT is present and the BKP domain is unlocked; contents persist across VDD power cycles if VBAT ≥ 1.8 V and backup domain is configured prior to standby entry.
