Power modes

The i.MX 8M Plus supports the following power modes:

•

RUN Mode: All external power rails are on, CPU is active and running; other internal modules can

be on/off based on application.

•

IDLE Mode: When there is no thread running and all high-speed devices are not active, the CPU

can automatically enter this mode. The CPU can be in the power-gated state but with L2 data

retained, DRAM and the bus clock are reduced. Most of the internal logic is clock gated but still

remains powered. The M7 core can remain running. Compared with RUN mode, all the external

power rails from the PMIC remain the same, and most of the modules still remain in their state.

NVCC_<XXX>

Imax = N x C x V x (0.5 x F)

Where:

N—Number of IO pins supplied by the power line

C—Equivalent external capacitive load

V—IO voltage

(0.5 x F)—Data change rate. Up to 0.5 of the clock

rate (F).

In this equation, Imax is in Amps, C in Farads, V in

Volts, and F in Hertz.
