148/272 DS11585 Rev 9
On-chip peripheral current consumption
The current consumption of the on-chip peripherals is given in Table 50. The MCU 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 19:
Voltage characteristics
• The power consumption of the digital part of the on-chip peripherals is given in
Table 50. The power consumption of the analog part of the peripherals (where
applicable) is indicated in each related section of the datasheet.
