Note:

1. The maximum current and power 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

(I/O) current and power are primarily dependent on the capacitive loading, frequency, and utilization of the external buses. The following

information provides details about the conditions under which the listed values were obtained:

a. In general, the values were measured using a PPC405GPr Evaluation Board with four PCI devices, an external bus master on

the

peripheral bus, and external wrap-back on the Ethernet port. For all CPU clock rates, PLB = 133.3MHz, OPB = PerClk = 66.6MHz,

PCI = SysClk = 33.3MHz.

to maximize CPU power consumption. An external PCI master heavily loads the PCI bus with transfers targeting SDRAM while the

internal DMA controller further increases SDRAM bus traffic.
