STMicroelectronics STM32F207VGT6J

Overview

STM32F207VGT6J 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, secure firmware updates, and deterministic network timing.

For engineers reviewing the STM32F207VGT6J datasheet, STM32F207VGT6J pinout, STM32F207VGT6J application, or STM32F207VGT6J equivalent, key selection criteria include Ethernet MAC + IEEE 1588v2 hardware timestamping capability, dual-CAN bus arbitration support, camera interface (DCMI) bandwidth up to 48 MB/s, and 138 5 V-tolerant I/Os for mixed-voltage system interfacing.

Technical Context

The STM32F207VGT6J integrates an Adaptive Real-time Accelerator (ART Accelerator™) enabling zero-wait-state execution from Flash at 120 MHz, coupled with a multi-AHB bus matrix for concurrent peripheral access. Its memory protection unit (MPU) supports secure task isolation in RTOS environments.

It implements two independent USB controllers: full-speed OTG_FS with on-chip PHY and high-speed OTG_HS with dedicated DMA and ULPI interface. The Ethernet MAC includes MII/RMII physical layer support and hardware-accelerated IEEE 1588v2 timestamping for precision time synchronization in industrial automation.

FAQ

Does STM32F207VGT6J support hardware-accelerated IEEE 1588v2 timestamping?

Yes. The Ethernet MAC includes dedicated hardware registers for precise packet timestamping on ingress and egress, enabling sub-microsecond accuracy required for Precision Time Protocol (PTP) slave operation in industrial Ethernet networks. This is confirmed in Section 3.26 of DS6329 Rev 18 and validated by register-level access to ETH_TSHR/TSLR and ETH_TSHUR/TSULR.

What is the maximum DCMI interface bandwidth supported by STM32F207VGT6J?

The Digital Camera Interface (DCMI) supports up to 48 MB/s data throughput, corresponding to 8–14-bit parallel pixel streams at up to 6 MHz pixel clock. This is specified in Section 3.31 and electrical timing Table 6.3.26 of DS6329 Rev 18, verified by DCMI_HSYNC/DCMI_VSYNC/DCMI_PCLK timing constraints.

Is STM32F207VGT6J pin-compatible with other STM32F207xx variants in LQFP100 package?

Yes. All STM32F207xx devices in LQFP100 (e.g., STM32F207VCT6, STM32F207VET6) share identical pinout and footprint per Table 8 (pin definitions) and Section 7.3 (package info) of DS6329 Rev 18. Differences are limited to Flash/RAM size and peripheral enablement - no pin function changes.

How many 5 V-tolerant I/Os does STM32F207VGT6J have, and which pins are they?

It has up to 138 5 V-tolerant I/Os, covering all GPIO ports (PA–PK) except analog inputs (e.g., ADC channels) and specific power-related pins (VCAP1/VCAP2). This is explicitly stated in the "Features" section and confirmed in Section 6.3.16 (I/O port characteristics) of DS6329 Rev 18.
