• EEPROM<br />
The board has 32Kb EEPROM. With the benefit of I2C bus, users could use it as residence of user<br />
data like version information, MAC address or other description substance. Figure 4-36 gives the<br />
schematic view of the EEPROM. The configured access address of EEPROM is 0xA0 for writing<br />
and 0xA1 for reading.<br />

• SD Card<br />
Many applications use a large external storage device, such as SD Card or CF card, for storing data.<br />
The <strong>DE2</strong>-<strong>115</strong> board provides the hardware needed for SD Card access. <strong>User</strong>s can implement<br />
custom controllers to access the SD Card in SPI mode and SD Card 4-bit or 1-bit mode. Figure<br />
4-37 shows the related signals.<br />
Finally, Table 4-27~Table 4-30 lists all the associated pins for interfacing FPGA respectively.<br />
