Electrical characteristics

On-chip peripheral current consumption

The current consumption of the on-chip peripherals is given in Table 29. The MCU is placed

under the following conditions:

•

All I/O pins are in analog mode

•

All peripherals are disabled unless otherwise mentioned

•

The given value is calculated by measuring the current consumption

–

with all peripherals clocked off

–

with only one peripheral clocked on

•

Ambient operating temperature and supply voltage conditions summarized in Table 15:

Voltage characteristics

•

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

Table 29. The power consumption of the analog part of the peripherals (where

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