STM32 Wireless MCUs external flash and ram capacity

[FlorentNapoleoni]

Hello,

I would like to know the capacity of external memories supported by STM32 MCUs wireless family :

- STM32WBA

- STM32WB

- STM32WB0

- STM32WL

 

I looked up in the datasheet of all referencies but I didn't find the information.

 

Thank you for your help.

 

Best Regards.

Welcome @FlorentNapoleoni, to the community!

The STM32Wx designed for wireless communication are optimized for very low power consumption, an external memory would significantly increase this power consumption, which is rather counterproductive for battery-operated devices.

What type and size of external memory do you need and what is the specific reason for this? You can connect external memory e.g. via SPI, but accessing the data located there is significantly slower compared to internal memory for several reasons.
