Overview

The STM32F105RBT6 is a Connectivity Line microcontroller featuring an ARM Cortex-M3 core running at 72MHz. It is specifically designed for applications requiring robust communication, offering dual CAN interfaces and a USB 2.0 OTG full-speed controller.

Why Choose This Part

This MCU provides a significant upgrade over standard F1 series parts by adding USB OTG and a second CAN interface while maintaining the familiar Cortex-M3 architecture. Its 64KB of RAM is generous for its class, facilitating larger buffers for communication stacks.

Applications

Industrial Gateways
Utilizing dual CAN 2.0B interfaces and five USARTs to bridge industrial fieldbus networks.
Automotive Aftermarket Tools
Ideal for OBD-II scanners and vehicle data loggers due to its integrated CAN controllers and USB connectivity.
USB Peripherals
Implementing USB OTG for devices that need to switch between host and device roles in the field.
Motor Control Systems
Leveraging 16-bit timers with PWM outputs and a 16-channel 12-bit ADC for precise sensor feedback.
