STMicroelectronics STM32F207VET6

Overview

STM32F207VET6 from STMicroelectronics is a 32-bit Arm® Cortex®-M3 microcontroller operating at up to 120 MHz, featuring 512 KB 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 networked edge control.

For engineers reviewing the STM32F207VET6 datasheet, STM32F207VET6 pinout, STM32F207VET6 application, or STM32F207VET6 equivalent, key selection criteria include Ethernet MAC timing compliance, dual-CAN arbitration latency, OTG HS ULPI interface readiness, and ART Accelerator™-enabled zero-wait-state Flash execution at 120 MHz.

Technical Context

The device integrates a multi-AHB bus matrix enabling concurrent access to Flash, SRAM, and peripherals including Ethernet DMA, USB OTG HS DMA, and FSMC - critical for deterministic data movement in protocol gateway applications. Its nested vectored interrupt controller (NVIC) supports 84 programmable interrupts with 16 priority levels, ensuring low-latency response to Ethernet packet arrival, CAN frame reception, and USB SOF events.

Clock architecture includes three PLLs: main PLL (up to 120 MHz), audio PLL (PLLI2S) for I2S synchronization, and dedicated USB OTG HS PLL - all independently configurable to meet simultaneous high-speed peripheral timing requirements without clock domain conflict.

FAQ

What is the maximum operating temperature rating for STM32F207VET6?

The STM32F207VET6 is qualified for industrial temperature range: –40°C to +105°C ambient. This rating is validated per AEC-Q100 stress tests and applies to all LQFP100 packages. Thermal derating begins above 85°C ambient when operating at full 120 MHz with all peripherals active, requiring ≥37 °C/W PCB thermal resistance.

Does STM32F207VET6 support USB device mode without external PHY?

Yes - the integrated USB OTG FS controller includes a full-speed on-chip PHY, enabling direct USB device mode (e.g., CDC ACM, HID, MSC) using only passive ESD protection. The OTG HS interface requires an external ULPI PHY (e.g., SMSC USB3343) for high-speed operation.

How many CAN interfaces does STM32F207VET6 have, and what protocol versions are supported?

The STM32F207VET6 integrates two independent CAN 2.0B controllers supporting both standard (11-bit) and extended (29-bit) identifier frames, with programmable bit rates up to 1 Mbps. Neither controller supports CAN FD; for CAN FD, consider STM32H7 or STM32G4 series devices.

Is the Ethernet MAC capable of full-duplex 100 Mbps operation without external components?

Yes - the integrated 10/100 Ethernet MAC supports full-duplex 100 Mbps in MII mode using only magnetics and RJ45 connector. RMII mode reduces pin count but requires a 50 MHz reference clock. No external PHY is needed for MAC-layer operation; however, physical layer signaling requires external magnetics and PHY-compatible layout.
