On-chip peripheral current consumption
The current consumption of the on-chip peripherals is given in Table 20. The MCU is placed
under the following conditions:
●
●
●
all I/O pins are in input mode with a static value at V or V (no load)
DD SS
all peripherals are disabled unless otherwise mentioned
the given value is calculated by measuring the current consumption
–
–
with all peripherals clocked off
with only one peripheral clocked on
●
ambient operating temperature and V supply voltage conditions summarized in
DD
