On-chip peripheral current consumption

The current consumption of the on-chip peripherals is given in Table 44. 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 16:

Voltage characteristics



The power consumption of the digital part of the on-chip peripherals is given in

Table 44. The power consumption of the analog part of the peripherals (where

applicable) is indicated in each related section of the datasheet.
