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.

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
