Product details
Overview
STM32F107RCT6 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 controller with on-chip PHY, and 10/100 Ethernet MAC with IEEE 1588 support. It operates at up to 72 MHz, integrates two 12-bit ADCs (16-channel, 1 µs conversion), two 12-bit DACs, and supports industrial networking gateways requiring real-time protocol bridging and deterministic communication.
For engineers reviewing the STM32F107RCT6 datasheet, STM32F107RCT6 pinout, STM32F107RCT6 application, or STM32F107RCT6 equivalent, key selection criteria include Ethernet MAC + USB OTG coexistence, dual-CAN timing synchronization, remappable I/O for PCB layout flexibility, and 5 V-tolerant GPIOs for mixed-voltage system interfacing.
Technical Context
The device implements a tightly coupled ARM Cortex-M3 core with single-cycle multiplication and hardware division, enabling deterministic interrupt latency and efficient real-time control. Its clock system includes three oscillators (HSE 3–25 MHz, HSI 8 MHz, LSE 32.768 kHz) and three PLLs supporting independent domain clocking for Ethernet, USB, and CPU subsystems.
Connectivity peripherals are hardware-optimized: the Ethernet MAC uses dedicated 4 KB SRAM and DMA with MII/RMII physical layer support; USB OTG FS includes integrated PHY, 1.25 KB SRAM, and HNP/SRP/ID session management; both CAN controllers feature 512 bytes of dedicated SRAM and full 2.0B Active compliance.

FAQ
What is the maximum operating temperature range for STM32F107RCT6?
The STM32F107RCT6 is qualified for industrial temperature range: –40°C to +85°C ambient. This is confirmed in Section 5.3.1 of the datasheet (DocID15274 Rev 10), with thermal characteristics validated for LQFP64 package under specified PCB copper area conditions.
Does STM32F107RCT6 support USB Host mode without external PHY?
Yes. The integrated USB OTG FS controller includes a full-speed transceiver PHY, enabling native USB Host, Device, and OTG functionality without external components. Hardware support for HNP, SRP, and ID detection is built-in per Section 2.3.22 of the datasheet.
Can the Ethernet MAC operate simultaneously with USB OTG and dual CAN?
Yes. The STM32F107RCT6's architecture allocates dedicated SRAM (4 KB for Ethernet, 1.25 KB for USB, 512 bytes per CAN) and independent DMA channels, allowing concurrent operation. Datasheet Section 2.3.20 confirms hardware isolation and priority arbitration between these peripherals.
Is the LQFP64 package of STM32F107RCT6 pin-compatible with other STM32F107x variants?
No. The LQFP64 variant (e.g., STM32F107RCT6) has different pin assignments than LQFP100 or LFBGA100 packages-even for identical functions like USB DP/DM or CAN TX/RX. Pin definitions are package-specific and documented separately in Tables 5 and Figures 3–4 of the datasheet.
