STM32WL5MOCH6 Frequency Range

Hello Everyone,

I'm checking the STM32WL5MOCH6TR MCU of a custom board that i made a few years ago, and I don't understand something : 

- On the datasheet, it says that its frequency range supported is 864–928 MHz

- When I open a CubeIDE project, I'm able to set a much wider range :

SubGHz_Phy example :

Is that intentional ? Maybe those Middlewares are general-purpose?

Hi Yaxsomo,

you can configure by software the frequency range from 150 MHz to 960 MHz which is supported by the STM32WL5x family. The config on cubeIDE are defined by regions based on the allowed frequencies on each one.

However, the the RF circuit (IPD + RF Switch) in the STM32WL5MOC is designed for the frequency range 864–928 MHz. Being outside of that range gives you poor performance.

    Note that the STM32WL5MOCH6TR is a module - not just an MCU:
