Supply current characteristics
The current consumption is measured as described in Section 5.1.7. It depends upon
several parameters, such as operating voltage, ambient temperature, I/O pin loading, device
software configuration, operating frequency, I/O pin switching rate, program location in
memory, and executed binary code.

1. VREFINT does not take into account package and soldering effects.
2. The shortest sampling time for the application can be determined by multiple iterations.
3. Specified by design, not tested in production.
4. Evaluated by characterization, not tested in production.
