TS-7250-V3 Power Consumption

From Technologic Systems Manuals

The TS-7250-V3's i.MX6UL CPU is very flexible with power. It can change the running frequency as needed to consume less power or to allow for more processing power.

The Ethernet can be put into a lower power state by bringing them up, and back down on startup. This is not done by default, and helps power savings regardless of if Ethernet is connected.

ifconfig eth0 up
ifconfig eth1 up
ifconfig eth0 down
ifconfig eth1 down
ifconfig wlan0 up # only needed if WIFI is present

These tests were run with 5V input. Unless otherwise specified these tests are run with no external connections except power, booted over eMMC at an idle prompt. The above ifconfig commands are included in our tests.

TS-7250-V3
Test Avg. (W) Peak (W)
Idle 0.77 1.29
CPU fully loaded [1] 1.03 1.45
CPU idle, single Ethernet port up and active [2] 1.17 1.75
CPU fully loaded [1], single Ethernet port up and active [2] 1.40 2.03
Silabs sleep mode (ARM CPU off) 0.055 0.063
  1. 1.0 1.1 This is accomplished by running stress-ng --matrix 0 -t 60m which generally consumes 100% CPU time
  2. 2.0 2.1 Using iperf to create bidirectional activity which adds minor CPU load
