Notes:

1. Core 1 characteristics apply only to MPC8640D

2. If two separate power supplies are used for VDD_Core0 and VDD_Core1, they must be at the same nominal voltage and the

individual power supplies must be tracked and kept within 100 mV of each other during normal run time.

3. Caution: D

_MV

IN must meet the overshoot/undershoot requirements for Dn_GVDD as shown in Figure 2.

4. Caution: L/TVIN must meet the overshoot/undershoot requirements for L/TVDD as shown in Figure 2 during regular run time.

5. Caution: OVIN must meet the overshoot/undershoot requirements for OVDD as shown in Figure 2 during regular run time.

6. Timing limitations for M,L,T,O)VIN and Dn_MVREF during regular run time is provided in Figure 2

7. The 2.5 V ± 125 mV range is for DDR and 1.8 V ± 90 mV range is for DDR2.

8. See Section 8.2, “FIFO, GMII, MII, TBI, RGMII, RMII, and RTBI AC Timing Specifications” for details on the recommended

operating conditions per protocol.

9. The PCI Express interface of the device is expected to receive signals from 0.175 to 1.2 V. For more information refer to

Section 14.4.3, “Differential Receiver (RX) Input Specifications."

10. Applies to Part Number MC8640wxx1067NC only. VDD_Coren = 0.95 V and VDD_PLAT = 1.05 V devices. Refer to Table 73

Part Numbering Nomenclature to determine if the device has been marked for VDD_Coren = 0.95 V.

11. This voltage is the input to the filter discussed in Section 20.2, “Power Supply Design and Sequencing” and not necessarily

the voltage at the AVDD_Coren pin, which may be reduced from VDD_Coren by the filter.

12. Applies to part number MC8640DTxxyyyyaC. Refer to Table 73 Part Numbering Nomenclature to determine if the device

has been marked for extended operating temperature range.
