Power modes

The i.MX 7Solo has the following power modes:

•

OFF mode: all power rails are off

•

SNVS mode: only RTC and tamper detection logic is active

•

LPSR mode: an extension of SNVS mode, with 16 GPIOs in low power state retention mode

•

RUN Mode: all external power rails are on, CPU is active and running, other internal module can

be on/off based on application;

•

Low Power mode (System Idle, Low Power Idle, and Deep Sleep): most external power rails are

still on, CPU is in WFI state or power gated, most of the internal modules are clock gated or power

gated

The valid power mode transition is shown in this diagram.
