STM32L011F4 power consumption

[krishna K H]

Hi team,

i need your help, i use STM32L011F4 controller ,This controller consuming 2mA current in sleep mode, as per datasheet it consumes only a less than 0.5mA current in sleep mode,

i can use only a I2C and RTC peripheral with 16MHz frequency.....

sleep mode function is

 HAL_PWR_EnterSLEEPMode(PWR_MAINREGULATOR_ON, PWR_SLEEPENTRY_WFI);

please help me how can i configured the controller? and how to reduce the power?

Thanks

Krishna

Any floating pin will ruin your current consumption. STM32L0 GPIO starts in analog mode, which is not suscensible to floating. However if you change any GPIO away from analog, you have to care for floating pins.
