STMicroelectronics STM32F207ZFT6

Overview

STM32F207ZFT6 from STMicroelectronics is a high-performance Arm® Cortex®-M3 microcontroller featuring 120 MHz CPU speed, 1 MB Flash, 132 KB SRAM (128+4 KB), dual CAN 2.0B interfaces, and integrated 10/100 Ethernet MAC with IEEE 1588v2 hardware support - deployed in industrial gateways requiring real-time protocol bridging and deterministic network timing.

For engineers reviewing the STM32F207ZFT6 datasheet, STM32F207ZFT6 pinout, STM32F207ZFT6 application, or STM32F207ZFT6 equivalent, key selection criteria include Ethernet MAC + USB HS/FS OTG coexistence, triple 12-bit ADCs (6 MSPS interleaved), camera interface (DCMI) bandwidth up to 48 MB/s, and 140 I/Os with 5 V tolerance - critical for multi-interface embedded control systems.

Technical Context

The STM32F207ZFT6 implements a tightly coupled Cortex-M3 core with Adaptive Real-Time Accelerator (ART™) enabling zero-wait-state execution from Flash at 120 MHz, MPU for memory protection, and multi-AHB bus matrix for concurrent peripheral access. Its clock system integrates HSE (4–26 MHz), HSI (16 MHz), LSE (32.768 kHz), and dual PLLs - one for system clock, one dedicated audio PLL (PLLI2S).

Peripheral architecture includes dedicated DMA channels for Ethernet MAC, USB OTG HS/FS, SDIO, and DCMI; flexible static memory controller (FSMC) supporting NOR/NAND/PSRAM; and nested vectored interrupt controller (NVIC) with 84 programmable IRQ lines - optimized for deterministic real-time response in protocol-aware edge nodes.

FAQ

What is the maximum operating temperature range for STM32F207ZFT6?

The STM32F207ZFT6 is rated for industrial temperature range: –40 °C to +105 °C ambient. This is validated per ST's DS6329 Rev 18 specification, with thermal derating applied above 85 °C ambient depending on PCB copper area and airflow. The LQFP144 package includes an exposed thermal pad to support sustained operation at upper limits.

Does STM32F207ZFT6 support USB Device and Host simultaneously?

Yes - it integrates two independent USB controllers: USB OTG FS (with on-chip PHY) and USB OTG HS/FS (with ULPI interface and dedicated DMA). This enables true concurrent device and host operation, such as acting as a USB mass storage device while enumerating a USB HID keyboard - confirmed in Section 3.28 and 3.29 of DS6329.

How many independent CAN interfaces does STM32F207ZFT6 provide?

The STM32F207ZFT6 includes two fully independent CAN 2.0B Active controllers (CAN1 and CAN2), each with its own message RAM, filters, and dedicated APB1 clock domain. Both support bit rates up to 1 Mbps and are electrically isolated in routing - verified in Table 3 and Section 3.27 of the datasheet.

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 1588-2008 (v2), enabling frame-level timestamp insertion and extraction with sub-100 ns resolution. This is documented in Section 3.26 and electrical specs Table 6.3.26 of DS6329 Rev 18.
