DC Electrical Specifications  
Table 7.3 below lists the worst case current consumption for each of the supplies of the LAN9215i.  
These figures are provided to assist system designers properly design the power supply; they cannot  
be used to determine typical power consumption of the device. All of these values are preliminary.  
Note: The current measurements listed below were taken under the following conditions:  
Temperature: .....................................................................................................................-40°C to +85°C  
Device VDD:....................................................................................................................+3.30 V +/- 10%
