AC electrical characteristics
Note:
IDDRUN
is the consumption in applications exploiting the full performances of the core. A
typical GPS application would run at 33MHz, at the maximum frequency (66MHz) the power
consumption is IDDRUN = 150 mA (typ).
In WFI mode the VReg and Flash are ON to guarantees the minimum interrupt response
time.
