On-chip peripheral current consumption
The current consumption of the on-chip peripherals is given in the following table. The MCU
is placed under the following conditions:
•
all I/O pins are in input mode with a static value at V
DD
or V
SS
(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
