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.

1 Caution: These are the recommended and tested operating conditions. Proper device operating outside of these

conditions is not guaranteed.
