On-chip peripheral current consumption

The current consumption of the on-chip peripherals is given in Table 51. 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 20:

Voltage characteristics

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

Table 51. The power consumption of the analog part of the peripherals (where

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