    S29GL064S90TFVV10 NOR-Flash buffer write timeout inquiry


      Dear All,,,


      I am now in NOR Flash Memory of Cypress

      We are testing our application using S29GL064S90TFVV.

      Buffer timeout occurs intermittently during buffer write operation.

      Please let me know how long you should set the maximum write buffer timeout value of the NOR Flash!

      Thank you.

          Thank you for contacting Cypress Community.


          Could you please explain your question? Are you asking how much maximum time should the controller wait after write buffer operation to ensure the program operation has completed successfully?

          If yes, I would like to inform you that it is highly recommended to poll the status of the DQ bits to determine the status of the flash after program/erase operations instead of waiting for a fixed time duration.
