Preliminary Data Sheet
440GR – PPC440GR Embedded Processor
Device Characteristics
Table 8. 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.

Notes:
1. If OVDD ≤ 0.4V, it is required that VDD ≤ 0.4V. Supply excursions not meeting this criteria must be limited to less than 25ms duration
during each power up or power down event.
2. The analog voltages used for the on-chip PLLs can be derived from the logic voltage, but must be filtered before entering the
PPC440GR. A separate filter, as shown below, is recommended for each voltage:
3. This value is not a specification of the operational temperature range, it is a stress rating only.
