Hi,
I'm working on STM32L496 for some security application, as per L4 series documents I see that L4 series controllers has AES hardware, but in my IOC settings under security option I don't see the AES.
Why is this? does it mean STM32L496 doesn't have AES hardware inbuilt? if yes is there any software approach?
Thanks

Hello @ML2020 ,
The STM32L496 does not support AES hardware accelerator.
It seems there is a mistake in the RM0351 rev 9 at beginning of chapter 28 page 833
Instead of
This section applies to STM32L49x/L4Ax devices only.
it should be
This section applies to STM32L48x/L4Ax devices only.
You can check in related datasheets.
Best regards

answering your question "if yes is there any software approach?"
if you want to do this by software you can used ST cryptographic library found in this link and a guide on how to incorporate it into you project in here .

There's always a software approach..

Hello @ML2020 and @Jocelyn RICARD ;
The reference manual issue is fixed in RM0351 Rev10.
Thank you.
