Dear Sir,

I have to interface Quad SPI  Winbond  part no: W25N512GVxIG/IT with TM4C129XCNZAD .

Facing issue in readout of Device ID . I have used the TM4C 129XCNZAD  interfaced with MX66L51235F code.

Please find the datasheet of winbond

    Hello Rajesh,

    We do not take responsibility for making a comparison on interface requirements between two devices from other companies as we have no knowledge of the individual device requirements.

    In general I would recommend looking at:

    • Verify the pinout match up
    • Check for any initialization requirements
    • See if there are differences in how to handle register reads/writes
    • Scope QSSI lines to see differences in communications which should give some clues where the code is not working as expected.

    Best Regards,

    Ralph Jacobi
