How much internal RAM does the MIMXRT1052CVL5B actually have?

Is it true that the internal RAM is only 512KB at most? Is the total RAM (ITCM/DTCM/SRAM) 512KB?

Or is it 512K SRAM + 512K TCM?

Hi @SDFDSFSF ,

Thank you for your question!

The MIMXRT1052CVL5B is not "512KB SRAM + 512KB TCM". Its total on-chip SRAM should be understood as 512KB; this 512KB is FlexRAM, which can be reallocated among ITCM, DTCM, and OCRAM.

You can find detailed instructions in AN12077 .

Best regards,
Gavin
