6.3.6 Supply current characteristics
The current consumption is a function of several parameters and factors such as the
operating voltage, ambient temperature, I/O pin loading, device software configuration,
operating frequencies, I/O pin switching rate, program location in memory and executed
binary code.
The current consumption is measured as described in Figure 20: Current consumption
measurement scheme.
All Run mode current consumption measurements given in this section are performed using
CoreMark code.

1. Guaranteed by design, not tested in production.
2. The reset temporization is measured from the power-on (POR reset or wakeup from V
BAT
) to the instant
when first instruction is read by the user application code.
