 FLASH

The board is assembled with 8MB of flash memory using an 8-bit data bus. The device 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. Connections between FPGA and Flash are shown

in Figure 4-35.

 EEPROM

The board has 32Kb EEPROM. With the benefit of I2C bus, users could use it as residence of user

data like version information, MAC address or other description substance. Figure 4-36 gives the

schematic view of the EEPROM. The configured access address of EEPROM is 0xA0 for writing

and 0xA1 for reading.
