Notes:
1. This is a maximum power supply number which is provided for power supply and board design information. The numbers are
based on 100% bus utilization for each component. The components listed are not expected to have 100% bus usage
simultaneously for all components. Actual numbers may vary based on activity.
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
two for the total. The other eTSEC protocols dissipate less than this number per port. Note that the power needs to be
multiplied by the number of ports used for the protocol for the total eTSEC port power dissipation.
4.This includes Local Bus, DUART, I2C, DMA, Multiprocessor Interrupts, System Control & Clocking, Debug, Test, Power
management, JTAG and Miscellaneous I/O voltage.
5. These power numbers are for Part Number MC8641xxx1000NX only. VDD_Coren = 0.95 V and VDD_PLAT = 1.05 V.
