Intel^® 82598EB 10 GbE Controller - EEUPDATE
Use a 128 Kb EEPROM for all applications until an appropriate size for each application is determined.
Recommended manufacturer and part numbers are Atmel’s AT25128N or Microchip’s 25LC128.
For more information on how to properly attach the EEPROM device to the 82598 controller please
follow the example provided in the Reference Schematic.
If no EEPROM device is used leave EE_CE_N, EE_SCK, EE_SI, EE_SO unconnected.
8.4.2 EEUPDATE
Intel has an MS-DOS* software utility called EEUPDATE, which can be used to program EEPROM images
in development or production environments. To obtain a copy of this program, contact your Intel
representative.
8.5
Connecting the Flash
The controller provides support for an SPI Flash device which will be made accessible to the system
through the following options:
• The Flash Base Address register (PCIe Control register at offset 0x14 or 0x18).
• An address range of the IOADDR register, defined by the IO Base Address register (PCIe) Control
register at offset 0x18 or 0x20).
• The Expansion ROM Base Address register (PCIe Control register at offset 0x30).
8.5.1 Supported EEPROM Devices
The controller supports SPI flash type. All supported Flashes have address size of 24 bits. TTable 8-3
lists the specific Flash types that are supported.
Table 8-3. Supported Flash Types
For more information on how to properly attach the Flash device to the controller, follow the example
provided in the Reference Schematic.
If no Flash device is used leave FLSH_CE_N, FLSH_SCK, FLSH_SI, FLSH_SO unconnected.
