How much SRAM does the i.MX RT 1015 have?

Hi All

 

Simple question which is answered in the data sheet:

 

 

But, when I try to configure its FlexRAM (which should have 4 banks of 32k each) I find that there are 8 banks and their default layout is the same a the RAM in the i.MX RT 1021, rather than 4 as in the i.MX RT 1011 - which indeed has 128k.

This means that I needed to use the same set up as I use on an i.MX RT 1021 since it would otherwise not work. And I have 256k of RAM to work in (and not the reported 128k).

 

Is the data sheet wrong or is my chip (on MIMXRT1015) strange???

 

Regards
