Freescale Semiconductor
Electrical and Thermal Characteristics
Table 2 lists recommended operational voltage conditions.
NOTE: Core, PLL, and I/O Supply Voltages
VDDH, VCCSYN, and VDD must track each other and both must vary in
the same direction—in the positive direction (+5% and +0.1 Vdc) or in the
negative direction (–5% and –0.1 Vdc).
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 VCC).
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.

conditions is not guaranteed.
