On-chip peripheral current consumption

The current consumption of the on-chip peripherals is given in Table 48. 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 18:

Voltage characteristics

•

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

Table 48. The power consumption of the analog part of the peripherals (where

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