Notes:

1. See “Absolute Maximum Ratings” on page 66 for filter recommendations.

2. SOVDD will be either +2.5V or +1.8V but not both.

3. 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, Ethernet, and so on).

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

4. Typical current is estimated at 667MHz with VDD = +1.5V, OVDD = +3.3V, EOVDD = +2.5V, SOVDD = +2.5V (DDR1) or +1.8V (DDR2),

and TC = +100°C with a typical process.

5. Maximum current is measured at 667MHz with VDD = +1.6V, OVDD = +3.45V, EOVDD = +2.6V, SOVDD = +2.6V (DDR1) or +1.9V

(DDR2), and TC = +100°C, and best-case process (which drives worst-case power).
