I know that for some AVR chips, running at 1.8v vs 3.3v or higher meant sacrificing cpu frequency. I can't find anything about this in the ATSAME54P20A's datasheet or the ATSAMD21J18A's datasheet. Does it just not matter for arm cores? What are the tradeoffs for running at a lower voltage than the usual 3.3v?
