The System Interface Extension connector J23 (P2) provides interfacing for the following:
• CompactFlash (CF) interface
• GPIO interfacing (EB405 only)
• USB interfacing
The Communications Interface connector J24 (P3) provides interfacing for the following:
• High Speed Serial (HSS) interfacing (TTL level) (SER1, SER2, SER3, SER4)
• Fast Ethernet (MDI interface)
• CAN
The Communications Interface Extension connector J20 (P4) provides interfacing for the fol-
lowing:
• Giga Ethernet (GMII interface, Three Speed Ethernet)
• X-bus (EB425 only)
• GPIO (EB425 only)

Board System and Communications Interfaces
The EBC2 supports a very comprehensive sub-set of the E²Brain system and communications
interfaces. Refer to the individual connector pinout descriptions for details.

Board-Level Interfacing Diagrams
The following five figures demonstrate the interfacing structure between the internal processing
elements of the EBC2 and other major EBC2 components. The interfacing lines are shown in
white where they are on board and in black for board external interfacing.
