The default configuration of the USB switch enables the USB HUB interface.  
Each of the USB interfaces provides control signals (Power_EN, Over_Current) for controlling an external 
USB power distributer located on the carrier board.  

2.3.2

 

Ethernet port 

The SPARK-100 supports a single 10/100/1000 Ethernet interface from the HPS (RGMII 1).

 

The Ethernet 

Phy in connected via an RGMII interface to the HPS. The following figure describes the Giga Ethernet 
interface.  

 

Figure 8 - Giga Ethernet & Fast Ethernet Interfaces 

The Ethernet PHY is KSZ9031 by Micrel. It uses an RGMII interface running at 125MHz. The 125 MHz 
clock is generated by the Ethernet PHY. 

The Ethernet PHY analog signals (TX+/-, RX+/-) are connected the SMARC edge connector. Two LED 
signals from the GE PHY are also connected to the SMARC edge connector. MDC/MDIO - The Ethernet 
MDC/MDIO signals are connected to the internal phy and are not available on the SMARC connector.  

2.3.3

 

UART  

The SOM offer one or two UARTs. Each UART includes Rx, Tx , CTS and RTS.  The HPS supports up to two 
UART interfaces. UART 0 is usually used for Linux CLI interface. Some of the UART signals share the same 
pins as the SPI interfaces which available on the SMARC connector. 

 

Programmable character properties, such as number of data bits per character, optional parity 

bits, and number of stop bits. 

 

Programmable baud rate. 

 

Automatic flow control mode per 16750 standard. 

 

The maximum UART baud rate is 6.25 mega symbols per second. 

2.3.4

 

CAN 

The HPS offers up to two CAN controllers 

based

 on the Bosch® D_CAN controller and offer the following 

features:
