TMS320F28377D: COTS vs EP, Functional safety-compliance and certification

Part Number: TMS320F28377D
Other Parts Discussed in Thread: , TMS570LC4357, TMS570LC4357-EP

Hello,

I am looking for a microcontroller that will have to work in harsh environment. I am considering, among others, these four:

  • TMS320F28377D
  • TMS320F28377D-EP
  • TMS570LC4357
  • TMS570LC4357-EP

As I understood, generally speaking, the -EP products are supposed to be more reliable and to be used preferentially in harsh environments and in sensitive applications. Therefore, I do not understand why they do not seem to be «Functional safety-compliant» as their standard counterparts.

It is not clear to me either, is it possible to use the safety libraries (like http://www.ti.com/tool/C2000-SAFETI-DIAGNOSTICS-LIB or http://www.ti.com/tool/SAFETI-HERCULES-DIAG-LIB-CSP) in the -EP parts the same way as the standard part ? There is a lot of information about that in the standard parts documentation, but I found nothing in the -EP documentation. And if – as I expect – it is indeed possible, does it facilitate safety certifications as for the standard parts?

The first prototype will a priori not need any certification. But it may probably be the case later on.

To summarize my questions:

  1. Why are only the standard parts Functional safety-compliant and not the -EP?
  2. Can I use the safety libraries and safety functions equally on both type?
  3. Does it affect certification in any way?

Thank you very much for your help, best regards
