STM32L151xx, STM32L152xx
On-chip peripheral current consumption
The current consumption of the on-chip peripherals is given in the following table. The MCU
is placed under the following conditions:
●
all I/O pins are in input mode with a static value at V
●
all peripherals are disabled unless otherwise mentioned
●
the given value is calculated by measuring the current consumption
