Product details
Overview
STM32F417IGT6 from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU, operating up to 168 MHz (210 DMIPS), featuring 1 MB Flash, 192+4 KB SRAM (including 64 KB CCM), dual USB OTG (FS/HS), 10/100 Ethernet MAC with IEEE 1588 support, and hardware crypto acceleration (AES-128/192/256, SHA-1, MD5). It targets industrial gateway controllers requiring real-time connectivity, secure firmware updates, and multi-interface coexistence.
For engineers reviewing the STM32F417IGT6 datasheet, STM32F417IGT6 pinout, STM32F417IGT6 application, or STM32F417IGT6 equivalent, key selection criteria include its dual USB OTG PHY integration, Ethernet MAC with dedicated DMA, triple 12-bit ADCs (7.2 MSPS interleaved), 140 GPIOs (138 5 V-tolerant), and LQFP176 package compatibility with camera interface (DCMI) and FSMC for external memory expansion.
Technical Context
The STM32F417IGT6 implements an Adaptive Real-time Accelerator (ART) enabling zero-wait-state execution from Flash at 168 MHz. Its memory subsystem includes CCM RAM for time-critical code/data, OTP for secure keys, and FSMC supporting NAND/NOR/PSRAM for HMI or data logging.
Connectivity is segmented across three domains: high-speed peripherals (USB HS, Ethernet, DCMI) on AHB, communication interfaces (3×I²C, 4×USART, 2×CAN, SDIO) on APB1/APB2, and analog subsystems (dual DAC, triple ADC, RNG, temperature sensor) tightly coupled to the core via DMA and interrupt routing.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-connectivity MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F427ZGT6 | Same core, +128 KB SRAM, no Ethernet MAC, adds Chrom-ART accelerator and FMC with SDRAM support. | Better suited for graphics-rich HMIs; lacks integrated Ethernet PHY interface and IEEE 1588 hardware. | Select when display performance outweighs industrial networking requirements. |
| STM32H743ZIT6 | Cortex-M7 @ 480 MHz, dual-core option, 1 MB Flash/1 MB RAM, no DCMI, adds DSI host and GPU. | Higher compute throughput for AI inference; replaces DCMI with MIPI DSI for embedded displays and omits hardware crypto for SHA-256. | Choose for next-gen edge AI where Ethernet is handled externally and display bandwidth exceeds LQFP176 pin count limits. |
Compared with STM32F427ZGT6, the STM32F417IGT6 trades graphics acceleration for deterministic Ethernet and camera I/O; versus STM32H743ZIT6, it offers lower BOM cost, proven industrial qualification, and pin-compatible migration path for legacy F4 designs requiring minimal rework.

FAQ
What is the maximum operating temperature range for STM32F417IGT6?
The STM32F417IGT6 is qualified for industrial temperature range: –40°C to +105°C ambient. This rating is verified per JEDEC JESD22-A104 and applies to all LQFP176 variants. Thermal derating begins above 85°C case temperature; PCB layout must include thermal vias under the exposed pad per datasheet Section 6.6.
Does STM32F417IGT6 support external SDRAM via FSMC?
No. The FSMC in STM32F417IGT6 supports NOR, PSRAM, NAND, and CompactFlash-but not SDRAM. SDRAM support requires the FMC peripheral found only in STM32F42xxx/F446xx/F7/H7 series. Attempting SDRAM connection to FSMC will result in timing violations and bus lockup.
Can the USB OTG HS interface operate without an external PHY?
No. USB OTG HS requires an external ULPI-compliant PHY (e.g., SMSC USB3343 or Microchip USB5744). The STM32F417IGT6 provides only the digital ULPI interface (D0–D7, CLK, DIR, NXT, STP); the analog transceiver, termination, and ESD protection are external responsibilities per datasheet Section 2.2.31.
How many independent PWM channels does STM32F417IGT6 support at 168 MHz?
It supports up to 36 independent PWM outputs: 12 timers × 4 channels each (TIM1–TIM5, TIM8–TIM11, TIM12–TIM14), all configurable at full 168 MHz clock. Channel polarity, dead-time insertion, and complementary output are supported on advanced-control timers (TIM1/TIM8) for 3-phase motor gate drive.
