Part 3: SPI Flash

The AC4040 FPGA core board A is equipped with one 64MBit SPI FLASH,

and the model is M25P64, which uses the 3.3V CMOS voltage standard. Due
to the non-volatile nature of SPI FLASH, it can be used as a boot device for the
system to store the boot image of the system. These images mainly include
FPGA bit files, core application code and other user data files. The specific
models and related parameters of SPI FLASH are shown in Table 3-1.
