DC Electrical Characteristics
NOTE: Core, PLL, and I/O Supply Voltages
After power up sequence is complete, VDDH and VDD/VCCSYN must
track each other and both voltages must vary in the same direction. When
varying in the positive direction, VDDH may vary up to 5% from nominal
or 3.3 + 0.165 = 3.465 V, in which case VDD/VCCSYN must also vary
upward by 5% from nominal or 1.525 + 0.075 = 1.6 V. The same applies
to the negative direction: VDDH may vary downward up to -5% from
nominal or 3.3 –0.165 = 3.135 V, in which case VDD/VCCSYN must vary
downward by-5% from nominal or 1.525 –0.075 = 1.45 V. A/C timing
specification violation may occur during the time that voltage tracking is
not correct.
This device contains circuitry protecting against damage due to high static voltage or electrical fields;
however, it is advised that normal precautions be taken to avoid application of any voltages higher than
maximum-rated voltages to this high-impedance circuit. Reliability of operation is enhanced if unused
inputs are tied to an appropriate logic voltage level (either GND or V
CC
).
Figure 2 shows the undershoot and overshoot voltage of the 60x and local bus memory interface of the
MPC8280. Note that in PCI mode the I/O interface is different.
