# SoC sleep

Source: [https://docs.qualcomm.com/doc/80-88500-4/topic/49_SoC_sleep.html](https://docs.qualcomm.com/doc/80-88500-4/topic/49_SoC_sleep.html)

The SoC resource sleep states are independent. In RPMh, there are no sleep
    modes.

The system sleep is tightly-coupled into the following sleep modes:

- XO shutdown
- Vdd minimization (Vdd\_Min)

The following sleep states are available for a resource:

- XO – off
- Vdd\_CX
    - Retention
    - Collapse (off)
- Vdd\_MX – retention
- AOSS – The sleep state occurs when the subsystem goes into a low-power state
