5. QSPI Flash
The board is assembled with 128Mbit of QSPI flash memory using an 4-bit data
bus. The flash device is N25Q128 which uses 3.3V CMOS signaling standard.
Because of its non-volatile property, it is usually used for storing software binaries,
images, sounds or other media. Detail information of QSPI FLASH is shown in table
2-5-1 below:
