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
