    External memory interface

    Hi All,

    I am looking for IC numbers for RAM so I can store my data in it. it shall be larger than 1 MByte.

    I hope it is fast enough because it will be shared between CPLD and AVR.

    did anyone succeed to interface with computers RAM ?

    Hi,

    I hope it is fast enough
    Designing electronics has nothing to do with hoping.

    Decide your specifications.
    Read datasheets.
    Do the calculations.

    "1 MByte" is a useful information. All other informations are just vague.

    Re: External memory interface

    We are speaking about 8 bit AVR? Does they support HW memory interfaces?
    Love me or hate me. All infractions will be ignored.

    Some do, some don´t.

    Those who have, have detailed datasheet section, with connection example.
