STMicroelectronics STM32F207ZCT6

Overview

STM32F207ZCT6 from STMicroelectronics is a high-performance Arm® Cortex®-M3 microcontroller featuring 120 MHz CPU clock, 256 KB Flash, 64+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 STM32F207ZCT6 datasheet, STM32F207ZCT6 pinout, STM32F207ZCT6 application, or STM32F207ZCT6 equivalent, key selection criteria include Ethernet MAC + IEEE 1588v2 hardware timestamping capability, dual-CAN redundancy for fieldbus interoperability, and parallel camera interface (DCMI) support up to 48 MB/s for embedded vision edge nodes.

Technical Context

The STM32F207ZCT6 integrates a Cortex-M3 core with Adaptive Real-Time Accelerator (ART Accelerator™), enabling zero-wait-state execution from Flash at 120 MHz. Its memory subsystem includes 256 KB of on-chip Flash, 64 KB main SRAM, and 4 KB battery-backed SRAM - all accessible via multi-AHB bus matrix for concurrent peripheral access.

It implements dedicated hardware blocks for time-critical connectivity: a full-featured 10/100 Ethernet MAC with MII/RMII PHY interface and IEEE 1588v2 timestamp registers, two independent CAN 2.0B controllers with programmable bit timing, and a 8–14-bit parallel DCMI supporting CCIR656 and ITU-R BT.601 video formats at up to 48 MB/s.

FAQ

Does STM32F207ZCT6 support hardware-based IEEE 1588v2 timestamping?

Yes. The integrated Ethernet MAC includes dedicated 64-bit timestamp registers and hardware capture logic for PTP event messages (Sync, Delay_Req, etc.), enabling sub-microsecond timestamp accuracy without CPU intervention or software stack jitter.

What is the maximum data rate supported by the DCMI interface?

The DCMI supports up to 48 MB/s in 14-bit parallel mode, corresponding to 640×480@60 fps raw Bayer data or 1280×720@30 fps YUV422 - verified in DS6329 Rev 18 Section 6.3.26 with timing constraints for HSYNC/VSYNC and pixel clock.

Can both CAN interfaces operate simultaneously with independent bit timing?

Yes. CAN1 and CAN2 are fully independent controllers with separate prescalers, time quanta registers, and acceptance filters - allowing concurrent operation on different baud rates (e.g., 500 kbps on CAN1 and 125 kbps on CAN2) without resource contention.

Is the 4 KB backup SRAM retained during Standby mode with VBAT supply?

Yes. When VBAT is applied and the backup domain is enabled, the 4 KB backup SRAM retains data across Standby mode entry/exit - confirmed in DS6329 Rev 18 Section 3.17 and electrical characteristics Table 25 (VBAT mode current consumption).
