Denitions of Idd Typical and Idd Maximum
These denitions apply to DC current specications given in the "DC Characteristics" table on page 42.
The typical DC current values represent the current drawn at nominal voltage with a typical, busy computing
load. Variations in the device, computing load, and system implementation affect the actual current.
The maximum DC current values will rarely, if ever, be exceeded running all known computing loads over
the entire operating range. The maximum values are based on simulations.

1. Even with the recommended bypass capacitance, there will be some dv/dt due to dynamic load variation. This 0-20 MHz dv/dt may be up to
100mV and is not included in the VDD requirements.
