Chapter 1: SP605 Evaluation Board

4. Linear BPI Flash

A Numonyx JS28F256P30 Linear Flash memory (U25) on the SP605 (Figure 1-5) 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 “Configuration Options.”
