    Hi Kaka-san,

    I did parsed the Micron SPI Flash datasheet and it looks ok to me including operating voltage.

    But suggest you to reconfirm on the below operating conditions for SPI flash to work.

    • The device must support at least a 500-kHz SPI clock.

    • The device uses three bytes (24 bits) for internal addressing (up to 16MB).  -  Though the other Flash device supports upto 32MB

    • The device must have the capability to auto-increment its internal address counter to allow sequential reads from the device. - This looks like its supported. 

    • Any and all write-protect features must be disabled if re-authoring is needed.  - Recheck and confirm (if re-authoring)

    Hope this helps.

     

    Regards

    >>Though the other Flash device supports upto 32MB
    What does it mean "the other flash"?
    And can C5535 support the 32MByte flash size in maximum?
    ** The bootloader is described " (up to 16MB).".

    Best regards.

    Vasanth:   By "other flash" -  I meant the  Flash: N25Q032A13EF440F 


    And can C5535 support the 32MByte flash size in maximum? ** The bootloader is described " (up to 16MB).".

    Vasanth:  C5535 with 24-bit SPI can support up to 16MB, you could use bigger flash but not all memories can be accessed.

     

    Hope this clarifies.

    Regards
