STM32F303CB (32k RAM. 128k Flash)

Contents

Hardware

Platform :ref:`platform_ststm32`: The STM32 family of 32-bit Flash MCUs based on the ARM Cortex-M processor is designed to offer new degrees of freedom to MCU users. It offers a 32-bit product range that combines very high performance, real-time capabilities, digital signal processing, and low-power, low-voltage operation, while maintaining full integration and ease of development.

Microcontroller STM32F303CBT6
Frequency 72MHz
Flash 128KB
RAM 32KB
Vendor Generic

Configuration

Please use genericSTM32F303CB ID for :ref:`projectconf_env_board` option in :ref:`projectconf`:

[env:genericSTM32F303CB]
platform = ststm32
board = genericSTM32F303CB

You can override default STM32F303CB (32k RAM. 128k Flash) settings per build environment using board_*** option, where *** is a JSON object path from board manifest genericSTM32F303CB.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:genericSTM32F303CB]
platform = ststm32
board = genericSTM32F303CB

; change microcontroller
board_build.mcu = stm32f303cbt6

; change MCU frequency
board_build.f_cpu = 72000000L

Uploading

STM32F303CB (32k RAM. 128k Flash) supports the following uploading protocols:

  • blackmagic
  • cmsis-dap
  • jlink
  • stlink

Default protocol is stlink

You can change upload protocol using :ref:`projectconf_upload_protocol` option:

[env:genericSTM32F303CB]
platform = ststm32
board = genericSTM32F303CB

upload_protocol = stlink

Debugging

:ref:`piodebug` - "1-click" solution for debugging with a zero configuration.

Warning

You will need to install debug tool drivers depending on your system. Please click on compatible debug tool below for the further instructions and configuration information.

You can switch between debugging :ref:`debugging_tools` using :ref:`projectconf_debug_tool` option in :ref:`projectconf`.

STM32F303CB (32k RAM. 128k Flash) does not have on-board debug probe and IS NOT READY for debugging. You will need to use/buy one of external probe listed below.

Compatible Tools On-board Default
:ref:`debugging_tool_blackmagic`   Yes
:ref:`debugging_tool_cmsis-dap`    
:ref:`debugging_tool_jlink`    
:ref:`debugging_tool_stlink`
