          At top of this page there is a "Part Search" window. enter "FM25*" (without the quotes) and search for. There are no obsolete parts within this category.

             

          You may select your required part and then directly click on "Datasheet" to retrieve your needed informations.

            Hi     

             

               

            Thanks for the reply     

             

               

            I checked the datasheet but it dose not have the sample code     

             

               

            It would be much appreciated if you can direct me any location which contains sample codes

               

             

               

            Thanks in advance

              Not as easy as to ask for. The memory chip has got a SPI interface which is hardware and must be routed correctly.

                 

              Coding depends on your processor, your IDE and your choosen language, all things nobody here knows about.

                 

              I would suggest you to:

                 

               

                 

              1st Build a SPI interface to your fram

                 

              2nd Program SPI to read fram's status register

                 

              3rd Set the Write Enable Latch (WEL)

                 

              4th verify success with 2nd

                 

              Now you can write and read to your fram
