STMicroelectronics STM32F207ZGT6

Overview

STM32F207ZGT6 from STMicroelectronics is a high-performance Arm® Cortex®-M3 microcontroller featuring 120 MHz CPU clock, 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 STM32F207ZGT6 datasheet, STM32F207ZGT6 pinout, STM32F207ZGT6 application, or STM32F207ZGT6 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 140 I/Os with 5 V tolerance for mixed-voltage system interfacing.

Technical Context

The STM32F207ZGT6 integrates a Cortex-M3 core with Adaptive Real-time Accelerator (ART Accelerator™) enabling zero-wait-state execution from Flash at 120 MHz, and includes a multi-AHB bus matrix for concurrent access to Flash, SRAM, and peripherals. Its memory subsystem supports external NOR/NAND/PSRAM via FSMC and features 96-bit unique ID plus CRC calculation unit for firmware integrity.

Timing architecture combines three independent clock domains (AHB/APB1/APB2), dual PLLs (main PLL + audio PLLI2S), and dedicated Ethernet DMA with MII/RMII physical layer support. The DCMI interface operates synchronously with pixel clocks up to 48 MHz, while dual CAN controllers share message RAM but maintain independent TX/RX FIFOs and filtering logic.

FAQ

What is the maximum operating temperature range for STM32F207ZGT6?

The STM32F207ZGT6 is rated for industrial temperature range: −40°C to +105°C ambient. This is validated per datasheet Section 6.3.1 and confirmed by thermal characterization in Section 7.7, supporting deployment in uncontrolled environments such as factory floors and outdoor enclosures without active cooling.

Does STM32F207ZGT6 support USB High-Speed device mode without an external PHY?

Yes - the STM32F207ZGT6 integrates a full-speed USB PHY and supports ULPI interface for external high-speed PHY connection. Its USB OTG HS peripheral includes dedicated DMA and on-chip FS PHY, enabling HS device/host operation when paired with a compliant ULPI PHY like SMSC USB334x.

How many independent CAN controllers does STM32F207ZGT6 integrate?

The STM32F207ZGT6 integrates two fully independent CAN 2.0B controllers (CAN1 and CAN2), each with dedicated message RAM, transmit/receive FIFOs, and filter banks. They operate concurrently without resource contention, verified in Section 3.27 and Table 3 of DS6329 Rev 18.

Is the Ethernet MAC capable of IEEE 1588v2 hardware timestamping?

Yes - the integrated 10/100 Ethernet MAC includes dedicated hardware timestamping logic compliant with IEEE 1588v2 Annex D, enabling sub-microsecond frame timestamp accuracy without CPU involvement. This is documented in Section 3.26 and electrical specs Table 6.3.26 of the datasheet.
