Hi,
We are working on railway projects where we are looking for SIL 2 microcontroller.
As per our analysis we found out that we need to integrate the X-CUBE-STL package to make it to SIL 2compliance. And we have found out that it should have supported MCU's. As per our analysis the STM32H5 and STM32H7 series supports X-CUBE-STIL package.
So, we wanted to know are the safety certified libraries available in this package to make it as SIL 2 compliance. Also, can you suggest if there are any SIL 2 certified microcontrollers available.
Regards,
Rajath
Solved! Go to Solution.

Correct, you'll get the NDA documents via your distributor.
Good luck!

Hi @Peter BENSCH,
Since we are working on railway projects, we have the requirement of using the motor.
We are currently evaluating motor controllers for a 48V BLDC motor application and have identified the STSPIN32F0B, which features an internal gate driver, as a potential candidate.
Before proceeding further, we would like to confirm whether this controller is SIL (Safety Integrity Level) compliant, as our application requires adherence to SIL standards.
Additionally, we would appreciate clarification on a general point:
Do motor controllers typically fall under SIL compliance requirements, or is this dependent on specific use cases or certifications?
Furthermore, if the STSPIN32F0B is not SIL-compliant, we would be grateful if you could suggest any SIL-compliant motor controllers suitable for 48V BLDC motor control applications.

I have worked for a company with SIL products - my job was luckily in a "pre-development" department where we could simply play with and test new controllers / sensors.
But the product development department had as many SIL-experts as development engineers, alone the testing regimen...
So, judging by your questions I would advise to find some experts - it's much more than choosing the right controller and SW package.

I would definitely second that, dealing with software for SIL-2 systems as well.
