Other Parts Discussed in Thread: SM320F28335-EP
HI Team,
I am using this controller but the core voltage is lower.
I have other controllers in comparison, SM320F28335-EP.
What is the rational for using 1.8V and 1.2V as core voltage.
To conclude.

This is dependent on the technology node (transistor size) used on the particular device, as well as to limit power dissipation on chip as devices move to smaller/newer nodes.
The F28335 device is based on 180nm transistor sizes, while the F28377D is a newer device that is based on 65nm transistor size.
Best,
