Quad SPI Flash Memory
On-board QSPI flash memory S25FL127SABMFV10 is used to store initial FPGA configuration. Datasheet is provided in Texas Instruments. Besides FPGA configuration, remaining free flash memory can be used for user application and data storage. All four SPI data lines are connected to the FPGA allowing x1, x2 or x4 data bus widths. Maximum data rate depends on the selected bus width and clock frequency used.

EEPROM
The Microchip Technology Inc. 24LC64 is 24xx64 is a 64 Kbit Electrically Erasable PROM. The device is organized as a single block of 8K x 8-bit memory with a 2-wire serial interface. Lowvoltage design permits operation down to 1.7V, with standby and active currents of only 1 μA and 3 mA, respectively. It has been developed for advanced, lowpower applications such as personal communications or data acquisition. The 24LC64 24xx64 also has a page write capability for up to 32 bytes of data. Functional address lines allow up to eight devices on the same bus, for up to 512 Kbits address space.
