[MK40DX128VMD10] Flash memory size is different.

Hello NXP

The flash memory size of operating feature on the NXP portal and flash memory size on datasheet are different.

I believe the value on datasheet is correct but I need your confirm.

Please see following pictures and let me know which one is correct.

Hi @waynejeong 

Many thanks for your patience and hoping you are well.

Effectively, the flash memory size from operating features on the NXP portal have an error. The correct flash memory size for this part number MK40DX128VMD10 is 128kB on Program flash memory size.

Thanks a lot for letting me know. If you have more questions, feel free to ask for us.

Sincerely,

Pablo Avalos

Hey, @waynejeong 

Hoping you are excellent and having happy holidays.

Just adding, the official NXP Portal might be confusing, because it considers Flash Memory such as real Flash Memory + FlexNVM (Non-Volatile Flash Memory), and the part number that you mentioned has a FlexNVM of 128KB, so together the regular flash and FlexNVM, form 256KB.

Please check this pdf on page 18 where you are able to see this information:

Let me know if you have more questions.

Regards.
