Typical IDD values are calculated as the mean value of current under the following conditions:
typically processed silicon, nominal supply voltage, T
otherwise specified), and a normal amount of traffic or signal activity. These values are suitable for
evaluating typical device performance in a system
Max IDD values are currents guaranteed by the production test program and/or characterization over
process for operating currents at the maximum operating voltage and operating temperature that
yields the highest current (including outputs loaded to 30 pF, unless otherwise specified)
Typical power values are calculated using the formula:
Where i denotes all the various power supplies on the device, VDDNomi is the nominal voltage for
supply i, and IDDTypi is the typical current for supply i (as defined in note 1 above). These values are
suitable for evaluating typical device performance in a system
High power values are a “normal high power” estimate and are calculated using the formula:
Where i denotes all the various power supplies on the device, VDDMaxi is the maximum operating
voltage for supply i, and IDDHighi is the current for supply i. IDDHigh values are calculated as the
mean value plus two sigmas (2σ) of measured current under the following conditions: T
outputs loaded with 30 pF (if not otherwise specified). These values are suitable for evaluating board
and device thermal characteristics.
Conditions
Power = ∑i(VDDNomi x IDDTypi)
Power = ∑i(VDDMaxi x IDDHighi)
