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 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
Table 37. Peripheral current consumption in Run or Sleep mode⁽¹⁾
Typical consumption, V_DD = 3.0 V, T_A = 25 °C
