Volume 2—Gigabit Ethernet (GbE) Controller—C2000 Product Family
Architectural Overview
11.5.1
PCIe* Integrated Endpoint
From a systems view, the GbE controller is a PCIe integrated endpoint consisting of one 
device with four functions. The device number is 20 decimal and its four function 
numbers are 0, 1, 2, and 3.
The controller is highly configurable. The device ID for each of the four functions are 
assigned, and its capabilities are enabled/disabled by the data contained in the 
controller’s EEPROM device. The configurable PCI and PCIe capabilities, and their 
offsets from the start of each function location in PCI configuration space are in 
.
The PCI Device IDs that can be assigned to a function via the EEPROM data:
• 0x1F40 - 1000BASE-KX (1 GbE) interface to backplane.
• 0x1F41 - Serial Gigabit Media Independent Interface (SGMII). Requires SGMII-
compliant PHY component. For guidance see a list in the appendix of the Intel
®
 
Atom™ Processor C2000 Product Family Platform Design Guide (PDG).
• 0x1F45 - 2500BASE-X (2.5 GbE) interface to backplane.
Note:
The “Dummy Function” Device ID that is available on some Intel LAN components is not 
supported by the SoC.
For information of the LAN interface and supported standards, see
