    The SD card can be interfaed by using SPI

     

    here is the link for SPI in ATmega16 tutorials:

    also see external EEPROM interfacing link(given on this site) it will help you in understand the memory architecture….

    Dear Hardeep,

     

                         I am glad to tell you that connections can be done through SPI and I am sending you Few Links.

     

    1. Link for Pin Connection of interfacing to your circuit.

     

         http://www.labbookpages.co.uk/electronics/avrs/sdCards.html

     

    2.Link for General purpose SD Card Datasheet.

     

         http://www.cypress.com/?docID=9706

     

    3.Link For standard Micro SD Card Datasheet.

     

        http://www.pqi.com.tw/upload/download/AE56-xxxx%281%29.pdf

     

    Refer it and connect it .
