1. 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. VDD (logic) current and
power are primarily dependent on the applications running and the use of internal chip functions (DMA, PCI Express, Ethernet, and so
on). OVDD (I/O) current and power are primarily dependent on the capacitive loading, frequency, and utilization of the external buses.
The information in this table provides details about the conditions under which the listed values were obtained. Maximum power is
measured on a best-case process (worst-case power) part running at 600MHz with a case temperature of +85°C and with voltages of
V
DD = +1.30V, OVDD = +3.45V, SVDD = +2.6V, and EOVDD = +2.6V while running Linux and test applications that exercise each
function with representative traffic (2 PCI Express, 2 Gigabit Ethernet, USB, Security).
