STM32F205VC - embedded SRAM Mapping

we are using the STM32F205VCT7 controller which should have 256k embedded flash and 96k embedded sram.


I am wondering now where the available SRAM is mapped.

It seems to be splitted into SRAM1 and SRAM2 where SRAM2 starts at 0x2001C000 and goes up to 0x20020000

But all memory mappings i found are showing the full 128k SRAM.



I have not found any memory mapping for the smaller devices like the STM32F205VC.


Is there 96k memory from 0x2000000 up to 0x20017FFF and then 32k "nothing".

Or is there a gap between SRAM1 and SRAM2?

==> SRAM1 from 0x20000000 to 0x20013FFF (80k)

==> SRAM2 from 0x2001C000 to 0x2001FFFF (16k)

==> nothing from 0x20014000 to 0x2001BFFF


And what will happen, if a non existing memory is accessed?


Does anyone know where to find this information?


Thank you.
