STMicroelectronics STM32F207ZCT7

Overview

STM32F207ZCT7 from STMicroelectronics is a high-performance Arm® Cortex®-M3 microcontroller featuring 120 MHz CPU operation, 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 deterministic network timing.

For engineers reviewing the STM32F207ZCT7 datasheet, STM32F207ZCT7 pinout, STM32F207ZCT7 application, or STM32F207ZCT7 equivalent, key selection criteria include Ethernet MAC + USB OTG HS coexistence, dual-CAN redundancy, DCMI camera interface timing (48 MB/s), ART Accelerator™-enabled zero-wait-state Flash execution, and 144-pin LQFP package I/O count (114 GPIOs with 5 V tolerance).

Technical Context

The STM32F207ZCT7 integrates a Cortex-M3 core with MPU and Adaptive Real-Time Accelerator (ART) for deterministic 120 MHz execution from Flash. Its multi-AHB bus matrix enables concurrent access to Flash, SRAM, FSMC, and peripherals without contention.

It implements two independent USB PHYs (FS on-chip, HS via ULPI), a full-duplex 10/100 Ethernet MAC with dedicated DMA and IEEE 1588v2 timestamping logic, and a parallel digital camera interface (DCMI) supporting 8–14-bit YUV/RGB formats at up to 48 MB/s - all synchronized via a shared APB/AHB clock tree with programmable prescalers.

FAQ

What is the maximum operating frequency and how is it achieved?

The STM32F207ZCT7 achieves 120 MHz CPU operation using its internal PLL driven by the HSE (4–26 MHz crystal) or HSI (16 MHz RC). The ART Accelerator™ eliminates Flash wait states at this frequency, enabling true zero-wait-state execution from internal Flash memory - verified in DS6329 Rev 18 Section 3.2.

Does STM32F207ZCT7 support IEEE 1588 Precision Time Protocol?

Yes - the integrated 10/100 Ethernet MAC includes dedicated hardware timestamping logic compliant with IEEE 1588v2, capable of inserting 64-bit timestamps into transmit packets and extracting them from received frames with nanosecond-level resolution, as specified in Section 3.26 of the datasheet.

Can the USB OTG HS and FS interfaces operate simultaneously?

No - the USB OTG HS and FS controllers share internal resources and cannot operate concurrently. The HS interface uses the ULPI bus (PB12–PB15), while FS uses the on-chip PHY (PA11/PA12); software must select one mode at boot via the OTG_FS_GCCFG register, per Section 3.29.

What is the DCMI interface's maximum pixel clock frequency and supported data width?

The DCMI supports pixel clocks up to 48 MHz and data widths of 8, 10, 12, or 14 bits - enabling 720p@30fps (1280×720×30 ≈ 27.6 MB/s) or VGA@60fps capture. Timing parameters are defined in Section 6.3.26 (DCMI timing specs) and Table 62 (clock timing), with hardware sync signal handling (VSYNC/HSYNC/PIXCLK) fully autonomous.
