The SoC includes two dedicated controllers to manage power: the platform management controller (PMC), and the processing system management (PSM) controller.

The PSM firmware controls the power islands and domains of the processing system. The PMC firmware controls the other power domains including the PL. The firmware manage isolation, reset, and power down.

The primary power domains for power management are listed in the following table.
Table 1. Primary Power Domains
Power Domain Description
PMC power domain Includes the RCU, PPU, PMC flash controllers, PMC I2C controller, and PMC GPIO controller. This is the power domain for device start-up.
Low-power domain (LPD) Includes the RPU, PSM, two SPI controllers, two LPD I2C controllers, LPD GPIO controller, UART controller, USB controller, PS gigabit Ethernet MAC, CAN FD controller, LPD SWDT, and CPM5 (device option) with its CPipe and GTYPs.
Full-power domain (FPD) Includes the APU, SMMU, CCI, and FPD SWDT.
Battery power domain (BPD) Includes the real-time clock (RTC) and the battery-backed RAM (BBRAM).
System power domain (SPD) Includes the NoC, NPI, DDR controller.
PL power domain Includes the programmable logic, PL GTs, integrated hardware and hardware options, and the PCIe coherency module (CPM, when present).
