Notes:  
1. PCI drivers meet PCI specifications.  
2. SVREF = SOVDD/2. SOVDD = +1.8V for DDR2 memory or +2.5V for DDR1 memory.  
3. The analog voltages used for the on-chip PLLs can be derived from the logic voltage, but must be filtered before entering the  
PPC440EPx. See “Absolute Maximum Ratings” on page 66.  
4. Startup sequencing of the power supply voltages is not required. A power-down cycle must complete (OV  
and V  
are below  
DD  
DD  
+0.4V) before a new power-up cycle is started  
5. At IOH = IOL= 10ma.  
6. Case temperature, TC, is measured at top center of case surface with device soldered to a circuit board.
