Interfacing a SRAM with Zedboard

Former Member

Hello All,

I need to connect an 8 bit SRAM (for instance, this: http://www.issi.com/WW/pdf/61LV5128AL.pdf ) to my Zedboard. I think I can make a PCB, solder the SRAM onto it and use the FMC connector in order to connect it to the Zedboard. However, I would like to seek for some cheaper and easier solutions first.

Do you have any advice or idea?

By the way, I don't need to drive the SRAM at full speed, I just need a SRAM connected to my Zedboard in order to develop a basic SRAM interface.

Thanks in advance,
mss

    Hi mss,

    I think unless you can find a demo board with the chip you are looking for pre-populated, you will need to spin a board.  Due to the pin count it is probably better to use the FMC, especially since it was physically setup to handle higher speeds.

    The other thing to be mindful of is the timing constraints.  As you move from prototype to production, you might need to adjust the constraints due to trace length or connector choice, etc.

    If you are not running at any great speeds, it may not matter as much, however just be aware of your constraints!

    Hi Dan,

    Firstly, thanks for the comment.

    Yes, FMC is the finest solution but I have some problems with it. If I will use FMC, I have two options; I have to make a custom PCB or I need to have a FMC prototyping board.

    Since, FMC connectors are not through hole and the leads are not visible for soldering with a soldering iron, I have to use a reflow oven. But, unfortunately, I don't own a reflow oven.

    On the other hand, FMC prototyping boards are too expensive. But, I think I don't have many options.

    Thanks for your comment again.
