2.2.2 Increased Current Consumption May Occur When VDD Drops

The device may experience increased current consumption of approximately 1.5 mA if VDD drops below 2.1V and is held in the range of 1.9-2.1V. This will only occur if VDD is originally at a higher level and then drops down to the mentioned voltage range.

Work Around

Ensure VDD is always kept above 2.1V by setting the BOR trigger level to 2.2V to keep the device from executing if VDD drops towards the affected voltage range. If operation in voltage range 1.9-2.1V is required, make sure VDD does not rise above 2.1V and then drops down again. Note that the voltage levels given are not absolute values but typical values.
