Data Sheet

Case Temperature rating for C package

+100

°C6

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

PPC440GP. See “Absolute Maximum Ratings” on page 55.

4. During chip power-up, OVDD should begin to ramp before VDD. External voltage should not be applied to the chip I/O pins before

OVDD is applied to the chip. A power-down cycle should complete (OVDD and VDD should both be 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.

Notes:

1. See “Absolute Maximum Ratings” on page 55 for filter recommendations.

2. The current values listed above are not guaranteed to be the highest obtainable. These values are dependent on many factors including

the type of applications running, clock rates, use of internal functional capabilities, external interface usage, case temperature, and the

power supply voltages. Your specific application can produce significantly different results. VDD (logic) current and power are primarily

dependent on the applications running and the use of internal chip functions (DMA, PCI, Ethernet, and so on). OVDD (I/O) current and

power are primarily dependent on the capacitive loading, frequency, and utilization of the external buses.

Recommended DC Operating Conditions (Continued)

Device operation beyond the conditions specified is not recommended. Extended operation beyond the recommended

conditions can affect device reliability.
