Current consumption measurement
Figure 19. Current consumption measurement scheme with and without external
SMPS power supply
The IDD_ALL parameters given in Table 26 to Table 48 represent the total MCU consumption
including the current supplying VDD, VDDA, VDDUSB and VBAT.

Absolute maximum ratings
Stresses above the absolute maximum ratings listed in Table 19: Voltage characteristics,
Table 20: Current characteristics and Table 21: Thermal characteristics may cause
permanent damage to the device. These are stress ratings only and functional operation of
the device at these conditions is not implied. Exposure to maximum rating conditions for
extended periods may affect device reliability. Device mission profile (application conditions)
is compliant with JEDEC JESD47 qualification standard, extended mission profiles are
available on demand.
