1. See “Absolute Maximum Ratings” on page 48 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.
