The markings on both the devices above look legit.

Thank you Vivek
Why the f28m36 doesn't have TI's logo on it?

When we built this version of the silicon we used a template for the symbol and this number signifies the TI logo. On the F2837x devices we have standardized the TI logo now.

The f28m36 silcon was made before the F2837x devices. That version of silicon we did not put the TI Logo that's all. No reason.
