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 22: Current consumption
measurement scheme.
All the run-mode current consumption measurements given in this section are performed
with a reduced code that gives a consumption equivalent to CoreMark code.

1. The product behavior is guaranteed by design down to the minimum V
POR/PDR
value.
2. Guaranteed by design, not tested in production.
3. The reset timing is measured from the power-on (POR reset or wakeup from V
BAT
) to the instant when first
instruction is fetched by the user application code.
