CC2340R5: Usable FLASH and RAM

Rahul
Intellectual 945 points
Part Number: CC2340R5

Tool/software:

Hi,

As per the chipset datasheet, it is mentioned that the CC2340R52E0RKPR has 512KB of FLASH and 36KB of RAM. I assume the default TI BLE stack may consume some of this memory. What will be the actual size of FLASH and RAM accessible to the user?

Thanks,

Rahul

    Hi Rahul,

    The exact size of FLASH and RAM accessible to the user will vary according to the SDK version, the configuration of the project (peripheral, central, ...) and compiler used (IAR or TIClang).

    However, in the 8.10 SDK, you can expect between 300 KB to 355 KB of Flash unused, and around 23 KB of RAM unused, do note that the System Reduce ~9KB from the Available RAM (Heap) on Boot and BLE Stack Init
