On-chip peripheral current consumption
The current consumption of the on-chip peripherals is given in the table below. The device is
placed under the following conditions:
• All I/O pins are in analog mode.
• The given value is calculated by measuring the difference of the current consumptions:
– when the peripheral is clocked on
– when the peripheral is clocked off
• Ambient operating temperature and supply voltage conditions summarized in Table 21:
Voltage characteristics.
• The power consumption of the digital part of the on-chip peripherals is given in the table
below. The power consumption of the analog part of the peripherals (where applicable)
is indicated in each related section of the datasheet.
