| |
The latest datasheet Rev. 0.1, 03/2020 removes below constrain:
"If VDD_SOC/GPU/DDR = 0.95V, then VDD_ARM must be >= 0.95V."
So, for 1.2GHz setpoint VDD_ARM can use its typical voltage directly.
The datasheet can be downloaded from below link: https://www.nxp.com/docs/en/data-sheet/IMX8MNCEC.pdf
