The document is referring to some K40 sub family. I don t understand the presentation of the Memory and memory interface on the first page of the document.
Since the DX devices support the FlexMemory, I need to understand where it is located.
The document says : Up to 512KB program flash memory on non FlexMemory devices.
Up to 256 KB program flash memory on FlexMemory devices.
Up to 256 KB program FlexNVM on FlexMemory devices.
This means a ..DX256.. device has 128KB of program flash AND 128KB of FlexMemory/FlexNVM ,
while a ..DN256.. device has 256KB of program flash And NO FlexMemory.
Is it correct???
