On-chip peripheral current consumption
The current consumption of the on-chip peripherals is given in Table 18. The MCU is placed
under the following conditions:
●
all I/O pins are in input mode with a static value at VDD or VSS (no load)
●
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 VDD supply voltage conditions summarized in
Table 5.
Table 18.
