Notes:
1. Power is based on VDD specified in the table and TC = max. specified in Table 10 on page 61, while running Linux and a test application
that exercises each core with representative traffic.

Notes:
1. See “Absolute Maximum Ratings” on page 61 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. VDD current and power are primarily
dependent on the applications running and the use of internal chip functions (DMA, PCI, Ethernet, and so on). OVDD current and power
are primarily dependent on the capacitive loading, frequency, and utilization of the external buses.
3. Typical current is estimated at 667MHz with VDD = +1.5V, OVDD = +3.3V, SVDD = +2.5V, and TC = +85°C, while running Linux and a test
application that exercises each core with representative traffic.
4. Maximum current is estimated at 667MHz with VDD = +1.6V, OVDD = +3.6V, SVDD = +2.7V, TC = +85°C, and a best-case process (which
drives worst-case power), while running Linux and a test application that exercises each core with representative traffic.
