Electrical Characteristics
Figure 3 shows the undershoot and overshoot voltage of the PCI interface of the MPC8347EA for the
3.3-V signals, respectively.

Output Driver Characteristics
Table 3 provides information on the characteristics of the output driver strengths. The values are
preliminary estimates.
2.2
Power Sequencing
The device does not require the core supply voltage and I/O supply voltages to be applied in any particular
order. Note that during the power ramp up, before the power supplies are stable, there may be a period of
time that I/O pins are actively driven. After the power is stable, as long as PORESET is asserted, most I/O
pins are three-stated. To minimize the time that I/O pins are actively driven, it is recommended to apply
core voltage before I/O voltage and assert PORESET before the power supplies fully ramp up.
