Solved
Currently, I am using STM32F417IG with a 3.3V supply. If I want to use a microcontroller with a 1.8V supply to avoid level translators in the new design. Is there anything I should consider if I change the supply voltage to 1.8V from 3.3V?

Hello
Yes, there are impacts when work on 1.8v
Increased flash wait states, reduced ADC sampling rates, reduced max clock output frequency on I/O pins, reduced max voltage for five volt tolerant pins and others .
Suggest to read carefully the Datasheet before decide to reduce the voltage.
