Power Consumption (Device Only)
This section provides typical power consumption values for the LAN9221/LAN9221i in various modes
of operation. These measurements were taken under the following conditions:
Temperature: ................................................................................................................................... +25°C
Device VDD (VDDVARIO, VDD33REG, VDD33A): ....................................................................... +3.30V
Note: Power dissipation is determined by operating frequency, temperature, and supply voltage, as
well as external source/sink requirements.
