__HAL_RCC_LSEDRIVE_CONFIG() WB55 vs WB5MMG

[DS.4]

I see a higher drive in the WB55MMG 

#ifdef WB55
__HAL_RCC_LSEDRIVE_CONFIG(RCC_LSEDRIVE_LOW);
#else WB5MMG
__HAL_RCC_LSEDRIVE_CONFIG(RCC_LSEDRIVE_MEDIUMHIGH);
#endif // MIGO_BORAD

 

would like to preserve as much power as possible, what are the consequences of using it _LOW?

Hello @DS.4 

It is recommended to use the LSE Medium-high drive to get a reliable LSE oscillation. It may work perfectly with the LOW drive, but we can't guarantee that.  

Best Regards.

Can you tell the effect it has on power consumption?

[STTwo-32]

Sure, the low drive is the best choice for power consumption. 

Best Regards.
