How to find out SPI controller version

seb234 · ‎2026-02-26

Hi,

I would like to know where I can find the SPI controller version of the STM32G491.

AN5543 lists features depending on the SPI controller version and says "To identify the version and the available feature set refer to the product reference manual and datasheet". However, I was not able to find this info in the RM or datasheet of the STM32G491 or anywhere else.

I guess you're referring to this:

I think what it means is that you look at the features in that table, compare to what features are actually listed in the RM for your particular chip - then that will tell you the version ?

Yes, it would be a lot more helpful to just state the version!

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.

Ah, I see. I think (unfortunately) you are correct.

Thanks
