SR-uSOM-MX6 Typical Power Consumption
The following power measurements were performed on a CuBox-i4pro based system, where
the main supply is 5V and internally a 5V to 3.3V LDO is being used on the carrier board
(refer to CuBox-i rev-1.1 schematics).

Note #3
Notes:
1. CuBox-i uses an LDO that provides 5V to 3.3V conversion that feeds the Ethernet
PHY on the MicroSOM. Due to that, the addition of 100mA on the 3.3V rail when
PHY is set to 1Gbps, adds 100mA consumption on the 5.0V power rails.
PHY is set to 1Gbps, adds 100mA consumption on the 5.0V power rails.
2. Notice the power difference between the same workload while Tjunction of the die
is 55c and 87c (~110mA difference from the 5V power rail).
It takes about 60 minutes to reach that stable 87c Tjunction.
It takes about 60 minutes to reach that stable 87c Tjunction.
3. This is using Linux suspend to memory when the front LED is off. This consumption is
mainly due to DDR entering self-refresh (2GByte) and some consumption on the
3.3V LDO and leakage on the processor and SoC digital part rails.
