Use of EFM8SB10F2G in jetson orin nano carrier board

  1. I’m confused about the use of EFM8SB10F2G MCU in carrier board design. is it just to maintain the time delay according to power sequencer?
  2. is it necessary to use this MCU or is there any other method to implement this functionality without any MCU.

Please refer to the Orin nano Design Guide and devkit carrier board P3768 schematic in DLC for that. MCU is not must, custom design should follow the power on sequence listed in Design Guide.
