Electrical characteristics
SPEAr600
3. The maximum current and power values listed above, obtained with typical supply voltages, 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.
1 V current and power are primarily dependent on the applications that are running and the use of internal
chip functions (DMA, USB, Ethernet, and so on).
3.3 V current and power are primarily dependent on the capacitive loading, frequency, and utilization of the
external buses.

Ratio of overshoot (or undershoot) duration with respect to
pulse width
If the amplitude of the overshoot/undershoot increases (decreases), the ratio of
overshoot/undershoot width to the pulse width decreases (increases). The formula relating
the two is:
Amplitude of OS/US = 0.75*(1- ratio of OS (or US) duration with respect to pulse width)
Note:
56/97
The value of overshoot/undershoot should not exceed the value of 0.5 V. However, the
duration of the overshoot/undershoot can be increased by decreasing its amplitude.
