About STM32WBA25 RAM Size for Multiple Functions

[CY_Tsai]

Hi

If I develop an application using the STM32WBA25 MCU with BLE, ThreadX, and USBX, is the RAM size sufficient?

96KB looks like decent amount of RAM  - but RTOSes such as ThreadX require a lot of RAM for thread stacks. So it highly depends on the number of your tasks/threads.

Hi @Pavel A. ,

Given that my application includes approximately 3 KB of historical data, a CC protocol using the FUSB302B, and a USBX CDC stack requiring at least 12 KB of memory, would you recommend continuing development with the STM32WBA25 series?

 

Sincerely.

Eric

Eric,

It looks feasible, but actually depends on the application RAM usage, on the compiler (some compilers optimize better) so it's hard to tell. Do you have alternatives?
