On-chip peripheral current consumption
The current consumption of the on-chip peripherals is given in Ta ble 2 0 . The MCU is placed
under the following conditions:
● all I/O pins are in input mode with a static value at V
DD
or V
SS
(no load)
● 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 V

2. Add an additional power consumption of 0.8 mA per ADC for the analog part. In applications, this
consumption occurs only while the ADC is on (ADON bit is set in the ADC_CR2 register).
