Detailed Description
4. Linear BPI Flash
A Numonyx JS28F256P30 Linear Flash memory (U25) on the SP605 (
) provides
32 MB of non-volatile storage that can be used for configuration as well as software
storage. The Linear Flash is operated in asynchronous mode.
For details on configuring the FPGA, see
