On-board quad SPI Flash memory S25FL127S (U5) is used to store initial FPGA configuration. Besides FPGA configuration, remaining free flash memory can be used for user application storage. All four SPI data lines are connected to the Zynq SoC's PS, allowing x1, x2 or x4 data bus widths. Maximum data rate depends on the bus width and clock frequency used.
