STM32WLE5x flash expansion

Hello,

I’m wondering if there is a solution to expand the flash memory of the STM32WLEx. I have noticed that the microcontroller do not the Quad-SPI interface. Is there any other possibility to see the external memory as memory mapped?

Any suggestion is welcome. 

Thanks

You'd likely need to attach a NOR Flash via SPI, and map/page code into RAM to execute.

Or pair with a more capable MCU. There are other L4 parts you could pair with a SX1276
