to note that the MCA power consumption is very stable in run-time and fluctuates very little
from one use case to another. So, for this element, only three use cases are represented:
suspend to RAM, power-off, and run-time.
Note These power consumption numbers should be considered guidelines only, never as fixed or
absolute values. Actual values will depend entirely upon individual setup and system application.
Note The wireless tests were run with the device in test mode. Since in test mode the system is
configured to work at 99% time transmitting, these values can be considered to be the highest power
consumption associated with each wireless mode. In real wireless transmission, many modes and
modulations may be used in a single connection depending on the environmental conditions, resulting
in different power consumption numbers. See Power consumption: Real wireless transmission.
Power consumption use cases
This section describes the use cases that were used to measure power consumption of the
ConnectCore 6UL module.
Suspend
System in suspend-to-RAM mode. The power consumption in this operation mode will be evaluated
when using and not using the PMIC Front-end LDO. See Power supply for more information about how
to power up the ConnectCore 6UL module.
CAUTION! You can achieve minimum power consumption numbers by disabling both
3.3V power domains. However, in some applications it may not be possible to switch
them off, depending on what they are powering.
Power-off
System in power-off with RTC enabled. RTC is running in the MCA. The power consumption in this
operation mode will be also evaluated when using and not using the PMIC Front-end LDO.
IDLE
System up and running. Ethernet and wireless disabled.
Decoding video
System up and running with the following configuration:
n Ethernet and wireless disabled.
n Fusion7 parallel display connected to the system.
Includes two different use cases:
n Display connected in IDLE mode (without decoding video).
n CPU decoding video.
CPU stress
System up and running with the following configuration:
