Hi, 

 

I am currently working with the STM32WB5MMG MCU and looking for some insights regarding its power consumption. Specifically, I would like to know:

  • What is the current consumption when the MCU is in STOP2 mode with the RTC enabled?

If anyone has experience or data on this, please share your insights. Any references to documentation or practical measurements would be greatly appreciated.

Thanks in advance!

Hello @SDhar.1

All the low power modes current measurements are available in the STM32WB55xx datasheet 

For STOP 2 mode RTC enabled, check this table:

What is the current consumption when the MCU is in STOP2 mode and Bluetooth is advertising?

 

If anyone has measured this or has any information, please share your findings. Any tips on optimizing power consumption in this scenario

Hello again @SDhar.1

When the STM32WB5MMG MCU is in STOP2 mode and Bluetooth is advertising, the current consumption can vary based on the advertising interval, the number of channels used, and the transmission power. 

Please check the following values in datasheet:
