Notes:
1. See “Absolute Maximum Ratings” on page 58 for filter recommendations.
2. The maximum 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. V
DD
(logic) current and power are
primarily dependent on the applications running and the use of internal chip functions (DMA, PCI, Ethernet, and so on). OV
DD
(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 are measured using a PPC440GX Evaluation Board set for Ethernet mode 4, PCI-X running at 100MHz with
an Intel Pro 1000, an Agilent Test card, an EBMI test card, a UART wrap plug, and one 128MB Micron DIMM while running
applications designed 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.
System clock rates are set as follows: SysClk = 33MHz, CPU = 667MHz, PLB = 167MHz, and OPB = EBC = 83MHz.
