STMicroelectronics STM32F417VET6TR

Overview

STM32F417VET6TR from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU, operating at up to 168 MHz (210 DMIPS), featuring 512 KB Flash, 192+4 KB SRAM (including 64 KB CCM), 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 secure fieldbus connectivity.

For engineers reviewing the STM32F417VET6TR datasheet, STM32F417VET6TR pinout, STM32F417VET6TR application, or STM32F417VET6TR equivalent, key selection criteria include Ethernet MAC timing compliance, dual-CAN arbitration latency, CCM RAM allocation for deterministic ISR execution, and ULPI interface signal integrity for high-speed USB peripheral attachment.

Technical Context

The device integrates a dual-bus AHB matrix enabling concurrent access to Flash, SRAM, and peripherals - critical for sustaining 54 MB/s parallel camera interface throughput while servicing Ethernet DMA and USB OTG HS transfers. Its ART Accelerator eliminates Flash wait states at 168 MHz, ensuring deterministic instruction fetch for hard real-time control loops.

Hardware cryptographic acceleration supports AES-128/192/256, Triple DES, and SHA-1/MD5 with HMAC, offloading TLS 1.2 handshake processing from the Cortex-M4 core. The dedicated Ethernet MAC includes MII/RMII PHY interface support, IEEE 1588v2 timestamping logic, and hardware-assisted checksum generation for TCP/UDP/IP packets.

Key Specifications

Pinout & Package

Equivalent & Alternatives

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

Compared with STM32F417VET6TR, the ZGT6 variant offers higher compute throughput but removes DCMI and one CAN interface - making it unfit for camera-integrated fieldbus gateways, while the ZGT6's larger package better serves complex I/O expansion needs.

FAQ

What is the maximum operating temperature range for STM32F417VET6TR?

The STM32F417VET6TR is rated for industrial temperature range: –40 °C to +85 °C ambient. Thermal characteristics in Section 6.7 of DS8597 Rev 9 specify junction-to-ambient thermal resistance (R_θJA) of 44.5 °C/W for LQFP100, requiring ≤1.2 W total power dissipation to stay within safe junction limits at 85 °C ambient.

Does STM32F417VET6TR support external SDRAM via FSMC?

Yes - the Flexible Static Memory Controller (FSMC) supports external SDRAM with row/column address multiplexing, refresh control, and burst access. Section 2.2.9 of DS8597 confirms SDRAM interface capability, and Table 8 lists dedicated FSMC signals (FSMC_SDCLK, FSMC_SDNWE, etc.) assigned to specific LQFP100 pins.

How is the USB OTG HS interface implemented on this part?

USB OTG HS uses a ULPI (UTMI+ Level 3) interface with dedicated DMA channel, on-chip full-speed PHY, and external high-speed PHY connection. Pin assignments (e.g., PA5/PA12 for ULPI_CLK/DIR) are defined in Table 7 of DS8597, and electrical timing complies with ULPI v1.1 spec per Section 5.3.21.

Can the CCM SRAM be used for DMA buffer storage?

No - CCM SRAM is accessible only by the Cortex-M4 CPU and cannot be targeted by DMA controllers. Section 2.2.6 of DS8597 explicitly states "CCM data RAM is not accessible by the DMA controller"; DMA buffers must reside in main SRAM (192 KB) or external memory via FSMC.
