Typicals are measured at 25°C.
Values given here are preliminary estimates prior to completing characterization.
All modules clocks switch on, code run from flash, FEI mode, and does not include any dc loads on port pins.
Most customers are expected to find that auto-wakeup from stop2 or stop3 can be used instead of the higher current wait
mode.
Values given under the following conditions: low range operation (RANGE = 0), low power mode (HGO = 0).
