Electrical characteristics
On-chip peripheral current consumption
The current consumption of the on-chip peripherals is given in Table 35. The MCU is placed
under the following conditions:
• All I/O pins are in analog mode
• 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 supply voltage conditions summarized in Table 21:
