On-chip peripheral current consumption
The current consumption of the on-chip peripherals is given in
. The MCU is placed
under the following conditions:
•
All I/O pins are in analog mode
•
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 supply voltage conditions summarized in
Table 32. Peripheral current consumption
