STM32F105RCT6 Connectivity-Line MCU | Cortex-M3 72MHz | USB OTG & Dual CAN | STMicroelectronics

STM32F105RCT6

32-bit connectivity-line MCU built on an Arm® Cortex®-M3 core running at 72 MHz, featuring 256 KB Flash and 64 KB SRAM, with USB OTG FS, dual CAN, and rich communication interfaces for industrial control, communication gateways, and application master controllers.

Product Description

Product Overview

The STM32F105RCT6 belongs to STMicroelectronics' STM32F105xx interconnect series, emphasizing a combination of connectivity and control capabilities. This series enhances USB OTG and CAN bus resources on top of the standard STM32F1 architecture, making it suitable for use as a communication hub or protocol gateway.

The chip uses a 72 MHz Arm Cortex-M3 core, supporting single-cycle multiplication and hardware division. Combined with 256 KB Flash and 64 KB SRAM, it provides ample computing and storage space for the TCP/IP protocol stack, USB protocol stack, and multi-task scheduling.

The STM32F105RCT6 integrates 2×12-bit ADCs, 2×DACs, up to 10 timers, and up to 14 communication interfaces (up to 2×I²C, 3×SPI/2×I²S, 5×USART, 2×CAN, 1×USB OTG FS), operating stably over a wide voltage range of 2.0–3.6 V and in industrial temperatures ranging from -40°C to +105°C.
