    Hi, I have a project in which I would need to get information from a certan Microprocessor http://www.emesystems.com/pdfs/parts/SX48BD.pdf [SX52BD/PQ] (the datasheet provides a similar model). And I have a FRAM memory RIC FM24C16-P http://www.digchip.com/datasheets/parts/datasheet/000/FM24C16-P-pdf.php.

    The main question is - Would I be able to download the program located on the memory and after that alter it. The program is written in assembler, but it doesn't really make much difference.

    And if I would be able to download it, than how?

    It depends on weather the security fuses have been programmed or not. If they have been programmed your only hope is to carefully slice open the package and using an electron microscope examine the memory cells one by one.

    See pp. 15-17 of the datasheet for information on the security fuses.
