STMicroelectronics STM32F207VFT6

Overview

STM32F207VFT6 from STMicroelectronics is an Arm® Cortex®-M3 32-bit MCU 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 STM32F207VFT6 datasheet, STM32F207VFT6 pinout, STM32F207VFT6 application, or STM32F207VFT6 equivalent, key selection criteria include Ethernet MAC+DMA integration, dual-CAN coexistence, ART Accelerator™-enabled zero-wait-state Flash execution, and 140 I/Os with 5 V tolerance for mixed-voltage system interfacing.

Technical Context

The device integrates a multi-AHB bus matrix enabling concurrent access to Flash, SRAM, and peripherals, with dedicated DMA channels for Ethernet (2), USB OTG HS (2), and camera interface (DCMI). Its clock system includes dual PLLs - main PLL for CPU/system clocks and audio PLL (PLLI2S) for precise I2S synchronization - plus independent 32 kHz RTC oscillator with calibration.

Peripheral coexistence is architecturally enforced: Ethernet MAC and USB OTG HS share no resource contention via separate AHB domains; DCMI supports 8–14-bit parallel input at up to 48 MB/s; and three 12-bit ADCs operate in triple interleaved mode delivering 6 MSPS aggregate sampling rate with hardware oversampling.

FAQ

Does STM32F207VFT6 support hardware-accelerated AES encryption?

No. The STM32F207VFT6 does not include a dedicated cryptographic accelerator. It relies on software libraries for AES, though its 120 MHz Cortex-M3 core and ART Accelerator™ enable efficient execution of lightweight crypto stacks. For hardware AES, consider STM32F417 or STM32H7-series MCUs.

What is the maximum achievable frame rate using the DCMI interface?

At 48 MB/s maximum DCMI bandwidth, the STM32F207VFT6 supports 720p (1280×720) video at 30 fps with 16-bit RGB565 format. Frame rate scales inversely with resolution and bit depth - e.g., VGA (640×480) at 60 fps or QVGA (320×240) at 120 fps - assuming DMA buffer management and sufficient SRAM allocation.

Can the Ethernet MAC operate in RMII mode with an external PHY?

Yes. The STM32F207VFT6 supports both MII and RMII physical layer interfaces. In RMII mode, it connects to external PHYs (e.g., LAN8720A) using 50 MHz REF_CLK, TXD[1:0], RXD[1:0], TX_EN, CRS_DV, and RX_ER signals - reducing pin count and PCB complexity versus MII.

Is the USB OTG HS interface functional without an external ULPI PHY?

No. USB OTG HS requires an external ULPI-compliant PHY (e.g., USB334x) for high-speed operation. The on-chip PHY supports only full-speed (12 Mbps) mode. HS functionality depends entirely on external ULPI PHY connection and proper impedance-controlled routing of ULPI data/control lines.
