(1) Total current measured on both AVCC and DVCC supplies.
(2) Calculated using the box method: (MAX(–40°C to 85°C) – MIN(–40°C to 85°C)) / MIN(–40°C to 85°C) / (85°C – (–40°C))
(3) Calculated using the box method: (MAX(1.62 V to 3.7 V) – MIN(1.62 V to 3.7 V)) / MIN(1.62 V to 3.7 V) / (3.7 V – 1.62 V)
