Product details
Overview
STM32F107RCT6TR from STMicroelectronics is a 32-bit ARM Cortex-M3 microcontroller in the Connectivity line, featuring 256 KB Flash, 64 KB SRAM, dual CAN 2.0B interfaces, USB OTG FS with on-chip PHY, and a 10/100 Ethernet MAC with IEEE 1588 support - deployed in industrial gateways requiring real-time protocol bridging and dual-network edge connectivity.
For engineers reviewing the STM32F107RCT6TR datasheet, STM32F107RCT6TR pinout, STM32F107RCT6TR application, or STM32F107RCT6TR equivalent, key selection criteria include Ethernet MAC timing compliance, CAN message buffer allocation, USB OTG host/device mode switching latency, and LQFP64 package thermal resistance under sustained 72 MHz operation.
Technical Context
The device integrates a single ARM Cortex-M3 core running at up to 72 MHz with 1.25 DMIPS/MHz performance, hardware division, and single-cycle multiplication. It supports full-speed USB OTG (with HNP/SRP/ID), MII/RMII Ethernet physical layer interfacing, and two independent CAN 2.0B controllers each backed by 256 bytes of dedicated SRAM.
Its clock system includes a 3–25 MHz external crystal oscillator, factory-trimmed 8 MHz RC, and 40 kHz RC for RTC; all peripherals-including 10 timers, 2×12-bit ADCs (2 MSPS interleaved), and 2×12-bit DACs-are synchronized via configurable APB/AHB bus matrix with pin remap capability for layout flexibility.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar connectivity-focused microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F107VCT6 | LQFP100 package (100 pins), adds 29 additional GPIOs and extra USART/I2C channels - no change in core, memory, or connectivity IP. | Required when board layout needs more peripheral routing flexibility or higher pin-count for expansion headers. | Select when >51 GPIOs are needed or when RMII/MII pin grouping conflicts occur in LQFP64 layout. |
| STM32F407VGT6 | Cortex-M4F core @ 168 MHz, FPU, 1 MB Flash, enhanced Ethernet MAC (with DMA descriptors), but no native CAN 2.0B - uses external CAN transceivers only. | Suitable for high-throughput data aggregation where floating-point math or larger code footprint dominates over dual-CAN requirement. | Choose only if CAN is handled externally and computational load exceeds Cortex-M3 capacity - not a drop-in replacement. |
Compared with STM32F107RCT6TR, the VCT6 offers pin-count scalability within the same architecture, while the F407VGT6 trades dual-CAN integration for raw compute and memory headroom - making the RCT6 optimal for cost-sensitive, dual-bus edge nodes where silicon-level CAN and Ethernet coexistence is mandatory.

FAQ
What is the maximum operating frequency and associated power consumption in Run mode?
The STM32F107RCT6TR operates at up to 72 MHz with typical active current of 36 mA at 3.3 V and 25°C when executing from Flash with all peripherals enabled. This value scales linearly with voltage and rises ~10% at 85°C ambient, per Section 5.3.5 of DocID15274 Rev 10.
Does this MCU support IEEE 1588 Precision Time Protocol (PTP) hardware timestamping?
Yes - the integrated 10/100 Ethernet MAC includes dedicated hardware registers for capturing transmit/receive timestamps with nanosecond resolution, enabling full PTP slave functionality per IEEE 1588-2008 without CPU intervention or software timestamp jitter.
Can the USB OTG interface operate in host mode without an external PHY?
Yes - the on-chip USB OTG FS PHY supports both device and host modes natively. In host mode, it drives standard USB 2.0 full-speed peripherals (e.g., HID, mass storage) directly via PA11/PA12, requiring only passive termination resistors per Figure 46 in the datasheet.
How many CAN message objects can be configured simultaneously?
Each of the two CAN controllers supports up to 14 transmit mailboxes and 16 receive FIFOs, with 512 bytes of dedicated SRAM split between them. Total configurable message objects exceed 60, enabling concurrent handling of multiple CAN IDs and filters in multi-network applications.
