Suggesstions about TMS750LS20216

Does that really require a processor specifically designed for safety-critical systems?

"how much the vendor assist for their product i.e example code, tutorials, technical support team etc."

Have you actually looked on the TI website to see what they have available?

Have you looked at their support forums, to see the level of activity there?

I can certainly tell you that TI provide excellent support for their Stellaris range via their forums - they are one of the very few companies where the support staff do actively participate in the forum.
[Keil et al take note!]

"Is there enough support for these devices form third party vendors? like debuggers/compilers etc."

That depends on what you mean by "enough" - doesn't it?

Again, the TI website should list 3rd-party support.

One thing to note, though, is that this chip is specifically targetted at safety-critical systems. That's a specialist market, which is bound to have less support than a "general purpose" product.

Also, safety-critical systems are, obviously, subject to stringent controls - so don't expect things to be "cheap" or "simple"
