The maximum power dissipation for individual power supplies of the MPC8641D is shown in
Freescale Semiconductor
Notes:
1. This is a maximum power supply number which is provided for power supply and board design information. The numbers are
2. Number is based on a per port/interface value.
3. This is based on one eTSEC port used. Since 16-bit FIFO mode involves two ports, the number will need to be multiplied by

multiplied by the number of ports used for the protocol for the total eTSEC port power dissipation.
