Product details

The STM32F105RCT6V is a 32-bit ARM Cortex-M3 microcontroller from STMicroelectronics' STM32F1 Connectivity line. It runs at 72 MHz and carries 256 KB of Flash program memory with 64 KB of SRAM.

At 72 MHz the Cortex-M3 executes single-cycle multiply and hardware divide. The 51 GPIOs, 16-channel 12-bit ADC, and dual 12-bit DAC let you close analog and digital control loops without external glue logic.

Connectivity mix — USB OTG and CAN

The STM32F105RCT6V carries USB OTG full-speed and two CAN 2.0B interfaces alongside I²C, SPI, UART/USART, IrDA, and LIN.

Frequently asked questions

What is the STM32F105RCT6V used for?

It is a 32-bit ARM Cortex-M3 MCU designed for industrial connectivity applications that require USB OTG and dual CAN interfaces, such as fieldbus gateways, motor drives with CANopen, and embedded data loggers.

What is the closest pin-compatible alternative to STM32F105RCT6V?

The STM32F107 series is pin-compatible with the STM32F105RCT6V and adds an Ethernet MAC, so a board designed for the F105 can accept an F107 with a firmware change.

What compliance documentation does STM32F105RCT6V carry?

STMicroelectronics provides RoHS and REACH compliance documentation for this part. The 64-LQFP package is lead-free and compatible with standard reflow profiles.
