Device Characteristics
Table 7. Absolute Maximum Ratings
The absolute maximum ratings below are stress ratings only. Operation at or beyond these maximum ratings can cause
permanent damage to the device. None of the performance specification contained in this document are guaranteed when
operating at these maximum ratings.

1. The analog voltages used for the on-chip PLLs can be derived from the logic voltage, but must be filtered before entering the
PPC440SPe. A separate filter, as shown below, is recommended for each voltage:
