On-chip peripheral current consumption

The current consumption of the on-chip peripherals is given in Ta bl e 2 8. 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)

● 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
