PowerPC 440SP Embedded Processor
Table 9. Recommended DC Operating Conditions (Sheet 3 of 3)
Device operation beyond the conditions specified is not recommended. Extended operation beyond the recommended
conditions can affect device reliability.

Notes:
1. PCI-X drivers meet PCI-X specifications.
2. SVREF = SVDD/2
3. The analog voltages used for the on-chip PLLs can be derived from the logic voltage, but must be filtered before entering the
PPC440SP. See “Absolute Maximum Ratings” on page 63.
4. Power supply sequencing: It is recommended that the 1.5V Vdd of the core reach its nominal value before applying power to the
I/Os. Voltage applied to I/Os from an external source must not be allowed to exceed the 0Vdd ramp. A power down cycle must
complete (0Vdd and Vdd are below 0.4V) before a new power up cycle is started.
5. LPDL is least positive down level; MPUL is most positive up level.
6. Case temperature, TC, is measured at top center of case surface with device soldered to circuit board.
