Overview

The STM32F105RCT6 is a Connectivity Line microcontroller featuring a 32-bit ARM Cortex-M3 core running at 72MHz. It provides 256KB of Flash memory and 64KB of RAM, specifically designed for applications requiring high-speed communication interfaces.

Why Choose This Part

The integration of dual CAN 2.0B controllers and USB 2.0 OTG FS makes this an ideal bridge for complex communication tasks. It maintains 5V-tolerant I/O and provides a high performance-to-power ratio with 72MHz operation and flexible low-power modes like Standby and Stop.

Applications

Industrial Gateway
Utilizing dual CAN interfaces and USB OTG to bridge industrial fieldbus networks with PC-based monitoring systems.
Automotive Aftermarket Tools
Implementing OBD-II diagnostic interfaces or vehicle data loggers that require robust CAN bus integration.
USB Peripheral Controller
Designing devices that need to switch between USB Host and Device roles using the integrated USB OTG Full-speed PHY.
Embedded Audio Systems
Leveraging the two 12-bit DACs and multiple SPI/I2S-capable interfaces for basic audio signal processing and playback.
