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

Table 39. Peripheral current consumption in Run or Sleep mode(1)
