also, mcu Nuvoton N76E003 Microcontroller will serve this purpose or any better nuvoton microcontroller for the same purpose????

Why are you sensing/measuring the mains voltage? If the mains fails then your micro loses its supply and won't be able to measure, control or display anything.
Is this a school/college assignment?
What is the starter intended to start? Certain loads might require sophisticated safety features.

MS51FB9AE Nuvoton MCU this would be useful for this project?
See post #9.
