3.1.5

Maximum supply currents

Power consumption is highly dependent on the application. Estimating the maximum supply currents

required for power supply design is difficult because the use cases that requires maximum supply current

is not a realistic use cases.

To help illustrate the effect of the application on power consumption, data was collected while running

consumer standard benchmarks that are designed to be compute and graphic intensive. The results

provided are intended to be used as guidelines for power supply design.

3.1.6

Power modes

The i.MX 8M Mini processors support 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

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.
