On-chip peripheral current consumption

The current consumption of the on-chip peripherals is given in the following tables. 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
