• The power consumption in Power-down mode is independent of clock selection.
• The current consumption is a function of several factors such as: operating voltage, operating
• The current drawn from capacitive loaded pins may be estimated (for one pin) as C

configured as inputs and with internal pull-ups enabled. A sine wave generator with rail-to-rail
output is used as clock source.
