7.10.2.4 Isolated MCU and Main Domains Power- Up Sequencing

Isolated MCU and Main voltage domains enable an SoC’s MCU and Main processor sub-systems to operate

independently. There are 2 reasons an SoC’s PDN design may need to support independent MCU and Main

processor functionality. First is to provide flexibility to enable SoC low power modes that can significant reduce

SoC power dissipation when processor operations are not needed. Second is to enable robustness to gain

freedom from interference (FFI) of a single fault impacting both MCU and Main processor sub-systems which

is especially beneficial if using the SoC’s MCU as the system safety monitoring processor. The number of

additional PDN power rails needed is dependent upon number of different MCU IO signaling voltage levels. If

only 1.8V IO signaling is used, then only 2 additional power rails could be required. If both 1.8 and 3.3V IO

signaling is desired, then 4 additional power rails could be needed.
