1. The typical current consumption values are given with PDR OFF (internal reset OFF). When the PDR is OFF (internal reset

OFF), the typical current consumption is reduced by additional 1.2 µA.

2. Based on characterization, not tested in production unless otherwise specified.

3. Based on characterization, tested in production.
