Low Power Run Mode in STM32WBxx

[DaveGoing]

I want to know if the STM32WB series can operate normally with a main frequency of 100 kHz in low-power-run mode, including the RF part?

Hello @DaveGoing 

According to the RM0473 part 6.4.2, In the Low-power run mode, the system frequency must not exceed 2 MHz
The Radio sub-system cannot be used in low-power Run mode. For more details you can refer to the Table 25. Functionalities depending on system operating mode. 

For the other STM32WB, the system frequency must be under 2 MHz and The Radio sub-system cannot be used in low-power Run mode. Also, you have to refer to the Power control chapter for more details.

Best Regards.
