Arduino Portenta C33

Hardware

Platform Renesas RA: Renesas Advanced (RA) 32-bit microcontrollers with the Arm Cortex-M33, -M23 and -M4 processor cores deliver key advantages compared to competitive Arm Cortex-M MCUs by providing stronger embedded security, superior CoreMark performance and ultra-low power operation.

Microcontroller	R7FA6M5BH2CBG
Frequency	200MHz
Flash	2MB
RAM	511.35KB
Vendor	Arduino

Configuration

Please use portenta_c33 ID for board option in “platformio.ini” (Project Configuration File):

[env:portenta_c33]
platform = renesas-ra
board = portenta_c33

You can override default Arduino Portenta C33 settings per build environment using board_*** option, where *** is a JSON object path from board manifest portenta_c33.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:portenta_c33]
platform = renesas-ra
board = portenta_c33

; change microcontroller
board_build.mcu = r7fa6m5bh2cbg

; change MCU frequency
board_build.f_cpu = 200000000L

Uploading

Arduino Portenta C33 supports the following uploading protocols:

• dfu

• jlink

Default protocol is dfu

You can change upload protocol using upload_protocol option:

[env:portenta_c33]
platform = renesas-ra
board = portenta_c33

upload_protocol = dfu

Debugging

Debugging - “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 Tools & Debug Probes using debug_tool option in “platformio.ini” (Project Configuration File).

Arduino Portenta C33 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
J-LINK		Yes
