Hello,

As i am designing a project for low power application. The best microcontroller that i had selected is STM32L053R8 which is cortex m0+. Now after drawing shematics according to my application requirement i found that the current consumption of the controller itself is 5mAmp. I am bit confused to see that the low power controller drawing so much of current. I have no clue to slove this issue . I kindly request you to provide me soultion for this. I here by attach controller part schematics that i had drawn uing eagle. If you require any further information regarding this issue i am happy to provide. If there is any problem with schemtics deisgns suggestions are taken in to consideration. Thanks,Best Regards,Sandeep. #lowpower #stm32 #nucleo

I recommend that you refer to the

which guides you to establish your design with the best recommendations. (start by adding capacitors between power supply and device’ Vdds)
