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.
