Notes:
1. Power is based on V_DD specified in the table and T_C = max. specified in Table 9 on page 59, while running Linux and a test application
that exercises each core with representative traffic.

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 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 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 V_DD = +1.5V, OV_DD = +3.3V, SV_DD = +2.5V, and T_C = +85°C, while running Linux and a test
application that exercises each core with representative traffic..
4. Maximum current is estimated at 667MHz with V_DD = +1.6V, OV_DD = +3.6V, SV_DD = +2.7V, and T_C = +85°C, and best-case process
(which drives worst-case power), while running Linux and a test application that exercises each core with representative traffic.
Test Conditions
Clock timing and switching characteristics are specified in accordance with operating
conditions shown in the table “Recommended DC Operating Conditions.” AC
Output
Pin
specifications are characterized with V_DD = 1.5V, T_C = +85 °C and a 50pF test load as
50 pF
shown in the figure to the right.
