Eurotech has pretested and approved various peripherals for use with the Vector. For the latest list,
check the Eurotech support site technical support.
Ethernet
For direct network connectivity, the Vector includes a Gigabit Ethernet Controller and the RJ-45 socket
J12 , page 31 . This RJ-45 socket includes two Ethernet LEDs , page 28 and built-in magnetics. The
processor enables the Ethernet Controller using the SMBus GPIO02. For details about this control
signal, see System Management I/O , page 21 .
CAN 2.0B
The Vector supports two CAN (Controller Area Network) buses on header J24 , page 34 and header
J25 , page 34 that are compliant with the CAN 2.0B specification. Each CAN 2.0B bus includes a CAN
controller, transceiver, common mode filter, and ESD protection. The CAN bus circuitry connects to
the LPC bus through a CPLD. This CPLD acts as an encoder/decoder translating data between the
LPC bus and the CAN controller and includes interrupt capability using the serial interrupt on the LPC
bus.

C (Inter-IC) bus is a multi-master, "two-wire" synchronous serial bus for communications between
integrated circuits (ICs) and for addressing peripherals in a system. The Vector embedded controller
acts as bus master and uses this bus to communicate with external devices on header J9 , page 30 .
The following diagram illustrates the I

C bus architecture on the Vector. Notice that the Vector does
not include termination on the I

C bus. Include external 10k Ω pull-up resistors to V3.3A.

C Bus Architecture
System Management Bus
System Management Bus (SMBus) is a serial interface allowing multiple devices to communicate with
each other. The Intel SCH US15W acts as bus master and uses this bus to communicate with an on-
board clock generator, the SODIMM SPD EEPROM, SMBus GPIO, and Keypad/GPIO. The bus is
also available externally on the Mini PCIe expansion slot J33 , page 36 .
The following diagram illustrates the SMBus architecture on the Vector.
