Product details
Overview
STM32F207VGT7 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 and deterministic network timing.
For engineers reviewing the STM32F207VGT7 datasheet, STM32F207VGT7 pinout, STM32F207VGT7 application, or STM32F207VGT7 equivalent, key selection criteria include Ethernet MAC + USB OTG HS coexistence, ART Accelerator™-enabled zero-wait-state Flash execution at 120 MHz, 140 I/Os with 5 V tolerance, and integrated DCMI for embedded vision edge nodes.
Technical Context
The STM32F207VGT7 integrates a dual-bus AHB matrix enabling concurrent access to Flash, SRAM, and peripherals - critical for sustaining 150 DMIPS while driving Ethernet DMA, USB OTG HS DMA, and camera interface simultaneously. Its ART Accelerator™ eliminates Flash wait states via instruction prefetch and branch cache, ensuring deterministic 120 MHz execution without external memory.
It features three independent clock domains (APB1 @ 30 MHz, APB2 @ 60 MHz, AHB @ 120 MHz), with dedicated PLLs for USB OTG HS (480 MHz), audio (PLLI2S), and system clock - allowing simultaneous high-speed USB, Ethernet, and I2S operation without clock contention or jitter accumulation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M3 @ 120 MHz; delivers 150 DMIPS with ART Accelerator™ for zero-wait-state Flash execution - enables real-time control loops without external RAM buffering. |
| Memory | 1 MB Flash + 128 KB SRAM + 4 KB backup SRAM; supports firmware updates in place and retains critical state during brownout via VBAT-supplied backup domain. |
| Ethernet Interface | IEEE 802.3 10/100 MAC with dedicated DMA and hardware IEEE 1588v2 timestamping - enables sub-microsecond time synchronization for industrial PLCs and motion controllers. |
| USB Connectivity | Dual USB controllers: OTG FS (on-chip PHY) + OTG HS (ULPI interface + dedicated DMA); allows simultaneous device/host roles and high-bandwidth data streaming (e.g., USB-to-Ethernet bridge). |
| Analog Peripherals | Three 12-bit ADCs (6 MSPS triple interleaved), two 12-bit DACs, temperature sensor, and VBAT monitoring - supports closed-loop analog sensing and actuation without external converters. |
| I/O & Timing | 140 I/Os (138 5 V-tolerant), 17 timers including two 32-bit general-purpose timers @ 120 MHz - enables precise PWM generation, quadrature encoder decoding, and multi-channel capture for motor control. |
| Communication Interfaces | 2× CAN 2.0B, 3× I2C, 4× USART + 2× UART, 3× SPI + 2× I2S, SDIO, DCMI (48 MB/s parallel camera) - supports fieldbus integration, wireless module interfacing, and machine vision preprocessing. |
Pinout & Package
LQFP100 (14 × 14 mm, 0.5 mm pitch) package with exposed thermal pad; 100-pin footprint optimized for industrial PCB layout with dedicated VCAP1/VCAP2 decoupling pins adjacent to VDD/VSS pairs and segregated analog/digital power domains.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VSS | Core power supply pair | 1.8–3.6 V main supply; requires separate 2.2 µF ceramic decoupling per VDD–VSS pair near pins 19/20 and 55/56 to stabilize ART Accelerator™ operation. |
| VCAP1, VCAP2 | Internal regulator bypass | Must connect 2.2 µF X7R ceramic capacitors directly to VCAP1 (pin 21) and VCAP2 (pin 57); failure causes boot failure or erratic Flash execution. |
| PA0–PA15, PB0–PB15, etc. | General-purpose I/O bank | 140 total I/Os grouped into GPIOA–GPIOI banks; each supports configurable pull-up/down, alternate functions (e.g., ETH_MII, USB_OTG_HS), and interrupt on change. |
| PH13–PH15, PI0–PI10 | DCMI interface | 12-pin parallel camera bus (HSYNC, VSYNC, PIXCLK, D0–D7, D8–D13); supports 48 MB/s throughput for VGA@30fps raw Bayer data ingestion. |
| PA1–PA7, PB12–PB13 | Ethernet MII/RMII | 25-pin MII or 9-pin RMII configuration; RMII mode reduces pin count while maintaining 100 Mbps full-duplex - ideal for space-constrained gateway designs. |
| PA11–PA12, PB14–PB15 | USB OTG FS/HS physical layer | PA11/PA12 = FS DP/DM; PB14/PB15 = HS ULPI CLK/DAT[0:7]; requires strict 90 Ω differential impedance routing for HS signal integrity. |
Key Features
| Feature | Design Value |
|---|---|
| ART Accelerator™ | Eliminates Flash wait states at 120 MHz - enables deterministic ISR latency ≤12 cycles and eliminates need for critical code relocation to SRAM. |
| Flexible Static Memory Controller (FSMC) | Direct NAND/NOR/PSRAM/CF interfacing with programmable timing - supports external 16-bit NOR flash boot or FPGA configuration memory mapping. |
| IEEE 1588v2 Hardware Timestamping | Dedicated timestamp registers synchronized to Ethernet PTP frames - achieves ±50 ns time accuracy for distributed motion control networks. |
| Dual USB OTG Controllers | Simultaneous FS device + HS host operation - enables embedded USB hub functionality (e.g., connecting USB cameras and Ethernet adapters to a single MCU). |
| Backup Domain Resources | 20 × 32-bit backup registers + 4 KB backup SRAM powered by VBAT - preserves calibration data and RTC alarm settings across full power cycles. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-performance ARM Cortex-M3 microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F407VGT6 | Higher clock (168 MHz), FPU, no Ethernet MAC, USB OTG HS only (no FS), 1 MB Flash/192 KB SRAM | Lacks integrated 10/100 Ethernet MAC and dual USB controllers - requires external PHY and USB transceiver for equivalent connectivity. | Select when floating-point math dominates workload and Ethernet is handled externally; avoid when board space or BOM count is constrained. |
| STM32H743VIT6 | Cortex-M7 @ 480 MHz, dual-core option, 2 MB Flash/1 MB SRAM, Ethernet + USB HS/FS, but no DCMI or FSMC | Replaces DCMI with MIPI DSI; FSMC removed in favor of OctoSPI - unsuitable for legacy parallel camera or NOR flash interfaces. | Choose for AI inference acceleration or GUI rendering; not drop-in for STM32F207VGT7 designs relying on DCMI or FSMC-based external memory. |
Compared with STM32F407VGT6, the STM32F207VGT7 provides integrated Ethernet MAC and dual USB without external components, reducing system complexity; versus STM32H743VIT6, it retains DCMI and FSMC for legacy industrial imaging and memory expansion - making it optimal for cost-sensitive, connectivity-rich edge nodes.

FAQ
What is the maximum operating temperature range for STM32F207VGT7?
The STM32F207VGT7 is rated for industrial temperature range: –40 °C to +105 °C ambient. This is validated per DS6329 Rev 18 Section 6.3.1, with thermal derating applied above 85 °C for sustained 120 MHz operation. The LQFP100 package's θJA is 44 °C/W, requiring ≥2 cm² copper pour under the thermal pad for full-range reliability.
Does STM32F207VGT7 support hardware encryption?
No, the STM32F207VGT7 does not include hardware AES or PKA accelerators. It features a true random number generator (RNG) and CRC calculation unit, but cryptographic operations require software libraries (e.g., mbed TLS). For hardware crypto, ST recommends STM32L4+, STM32G0, or STM32H7 series.
Can the Ethernet MAC operate in RMII mode with internal PHY?
No - the STM32F207VGT7 Ethernet MAC requires an external PHY for both MII and RMII modes. It provides only the MAC layer with dedicated DMA and IEEE 1588v2 timestamping logic; RMII signals (REF_CLK, CRS_DV, RXD[1:0], TXD[1:0], TX_EN) must be routed to a compliant PHY such as LAN8720A or DP83848.
How many VCAP capacitors are required, and what value?
Two 2.2 µF X7R ceramic capacitors are mandatory: one on VCAP1 (pin 21) and one on VCAP2 (pin 57). These stabilize the internal 1.2 V regulator powering the Cortex-M3 core and Flash memory. Using less capacitance or wrong dielectric causes boot failure or Flash corruption - confirmed in DS6329 Section 6.3.2.
