STMicroelectronics STM32F207VCT6TR

Overview

STM32F207VCT6TR from STMicroelectronics is a 32-bit Arm® Cortex®-M3 microcontroller operating at up to 120 MHz, featuring 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 STM32F207VCT6TR datasheet, STM32F207VCT6TR pinout, STM32F207VCT6TR application, or STM32F207VCT6TR equivalent, key selection criteria include Ethernet MAC DMA integration, dual-CAN bus arbitration capability, ART Accelerator™-enabled zero-wait-state Flash execution, and VBAT-backed RTC with 20×32-bit backup registers for secure timekeeping across power cycles.

Technical Context

The device implements a multi-AHB bus matrix architecture enabling concurrent access to Flash, SRAM, and peripherals without contention; its ART Accelerator™ uses prefetch and branch cache to eliminate Flash wait states at 120 MHz operation. The embedded Ethernet MAC includes dedicated DMA, MII/RMII PHY interface, and hardware timestamping aligned to IEEE 1588v2 for sub-microsecond synchronization.

Dual CAN 2.0B controllers operate independently with full message RAM buffering and programmable bit timing; the USB OTG HS interface integrates ULPI support and dedicated DMA, while the FS controller includes on-chip PHY. All timers (including TIM1/TIM8 advanced-control units) feature quadrature encoder input, PWM generation, and IC/OC capture with 120 MHz clock domain support.

FAQ

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

The STM32F207VCT6TR achieves 120 MHz maximum CPU frequency using the Arm Cortex-M3 core with ART Accelerator™, which combines prefetch and branch cache to eliminate Flash memory wait states. This enables deterministic 0-wait-state execution directly from internal Flash, verified under industrial temperature conditions (–40°C to +85°C) with 1.8–3.6 V supply.

Does this MCU support hardware-accelerated IEEE 1588v2 timestamping?

Yes - the integrated 10/100 Ethernet MAC includes dedicated hardware timestamping compliant with IEEE 1588v2, capable of inserting and extracting sub-microsecond-precision timestamps in PTP frames. This functionality operates independently of CPU load and is accessible via dedicated MAC registers and DMA descriptors.

How many CAN interfaces does the STM32F207VCT6TR provide, and what version do they support?

The STM32F207VCT6TR integrates two fully independent CAN 2.0B controllers, each with its own message RAM, programmable bit timing, and automatic retransmission logic. Both support standard and extended identifier formats, loopback testing, and silent mode - enabling dual-bus redundancy or protocol bridging without software arbitration.

What package type and pin count does the STM32F207VCT6TR use?

The STM32F207VCT6TR uses an LQFP100 package: 100-pin, 14 × 14 mm body, 1.0 mm pitch, with exposed thermal pad and RoHS compliance. Pin definitions are documented in Section 4 ("Pinouts and pin description") of DS6329 Rev 18, including dedicated MII, CAN, USB, and DCMI signal allocations.
