 I have my own product board with STM32L073VBT6.The power comsumption increase to 10mA (an other is 4mA) when enter low power mode.So I had removed all other chips only left the STM32 and found out that the MCU cost the 10mA. The function of the chip is ok. I Don't understand How the chip came to that with the function ok.

?????STM32L073??pCB????????10mA??????????????IC??????????3?mA????????????????????????

Unfortunately your post lacks sufficient detail to replicate or understand the circuit and software as implemented.

Is this with a debugger attached?

How to you make a determination about the internal state of the processor?

Sleep/Standby?

External buffers, LEDs, pull up/down resistors?
