I3C compatible boards

[DanLumi]

Hi there,

I'm looking for development boards that can support I3C at full SDR speed (12.5MHz), and I have the following MCUs that we can try I3C from the AN5879 application note:

• STM32H5 series.
• STM32H7R3/7S3 line.
• STM32H7R7/7S7 line.

On the other hand, I found STM32H7B3I-DK, which can work with the integrated peripherals without adding extensions, but it uses the STM32H7B3LIH6QU chip (STM32H7B3), which is not in the list above.

Is there any update from the AN5879's release date (June 2024) with I3C-compatible MCUs so we can find more development boards to try I3C?

Also, does ST maintain a place to check for updated I3C-compatible MCUs and boards?

Thank you,

Daniel.

Hi @DanLumi ,

STM32H7Bx doesn't support I3C.

With MCU/MPU Selector (in STM32CubeMX or MCUFinder), you can look for MCUs with I3C and you have also proposals for boards containing it. I made the exercise and this is what I get as result: 

I assume that a new version of AN5879 will be available soon to support STM32N6.

Thanks @Amel NASRI. That will help to search for I3C-enabled MCUs.
