4.3Power Consumption

This section details the power consumption of LAN9500/LAN9500i as measured during various modes of operation. Power consumption values are provided for both the device-only, and for the device plus Ethernet components. Power dissipation is determined by temperature, supply voltage, and external source/sink requirements.
