On-chip peripheral current consumption
The current consumption of the on-chip peripherals is given in Ta bl e 1 8 . 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
● ambient operating temperature and V
DD
supply voltage conditions summarized in
Ta bl e 5 .
5.3.6 External clock source characteristics
High-speed external user clock generated from an external source
The characteristics given in Ta b le 1 9 result from tests performed using an high-speed
external clock source, and under the ambient temperature and supply voltage conditions
summarized in Tab l e 8 .
