power consumption
typical current consumption BATT:
3 µA
maximum power consumption BATT:
10 µA @25°C
Thermal design power (summary all chips)
With 1GHz SoloX CPU
5.5 Watt @25°C
Additional with Wifi mounted
+1.6 Watt @25°C
Maximum output current VLCD
500 mA
Maximum output current V33-Enable
100 mA
Power consumption of connected devices like display, USB devices, SD card, miniPCIe card
has to be added for power calculation.
Real power consumption could be much lower depends CPU workload, used graphic
interfaces and features and the workload on I/O interfaces.
