age. The device is only gauranteed to operate correctly within this area. Note that the on-chip
Brown-out Detector (BOD) has a minimum threshold of 1.8V. Systems that rely on this BOD to
prevent incorrect operation due to power loss should only operate at 12 MHz or below. Systems
at higher frequencies may require an external BOD.

The following charts show typical behavior. These figures are not tested during manufacturing.
All current consumption measurements are performed with all I/O pins configured as quasi-bidi-
rectional (with internal pull-ups). A square wave generator with rail-to-rail output is used as an
external clock source for consumption versus frequency measurements.
