Is bank swap of stm32h523VCT6 possible?

[Roy_Lee]

I checked the datasheet and there is a memory map of 521Kbyte.
But I use the stm32h523VCT6 chip.
This chip has 256Kbyte of memory.
Can't a chip with 256Kbyte of memory use bankswap?
If it can, can you tell me the memory address?

Look in manual, to be sure... (i am just guessing, from my H743ZG and H743ZI ....same chip): 

bankswap for 512K cpu is 2x 256K; (continuous memory area);

bankswap for 256K cpu is 2x 128K , same address for start of ram area, just ram is no more continuous.

btw

chip should be the same, so your 256K cpu also has 512K ram, just check it.

Only problem: its not tested and no guaranty to work; only the 256K, you payed for, is tested.

Yes, the STM32H523VCT6 chip, which has 256 Kbytes of memory, supports bank swapping as indicated in the provided table from reference manual.
