8 / 140 page  MPC8640 and MPC8640D Integrated Host Processor Hardware Specifications, Rev. 1 8 Freescale Semiconductor Electrical Characteristics eTSEC 3 and 4 I/O supply voltage TVDD 3.3 V ± 165 mV V 8 2.5 V ± 125 mV V 8 Local Bus, DUART, DMA, Multiprocessor Interrupts, System Control & Clocking, Debug, Test, Power management, I2C, JTAG and Miscellaneous I/O voltage OVDD 3.3 V ± 165 mV V 5 Input voltage DDR and DDR2 SDRAM signals D n _MVIN GND to D n_GVDD V3, 6 DDR and DDR2 SDRAM reference D n _MV REF D n_GVDD/2 ± 1% V Three-speed Ethernet signals LVIN TVIN GND to LVDD GND to TVDD V4, 6 DUART, Local Bus, DMA, Multiprocessor Interrupts, System Control & Clocking, Debug, Test, Power management, I2C, JTAG and Miscellaneous I/O voltage OVIN GND to OVDD V5,6 Junction temperature range TJ 0 to 105 °C -40 to 105 12 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 n _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. Table 2.
