MPC826xA (HiP4) Family Hardware Specifications
MOTOROLA
Electrical and Thermal Characteristics
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.
