The FC601 USB OABR Stick represents a compact hardware interface connecting MS-Windows and Linux based PCs with automotive Ethernet network devices and switches. Automotive Ethernet network standards OABR (OPEN Alliance BroadR-Reach) and 100Base-T1 are supported.

The FC601 USB OABR Stick functions as seamless media converter between a standard USB 2.0 interface and an automotive Ethernet network. On Windows and Linux host PCs the FC601 USB OABR Stick is detected as standard Ethernet device.

Flexible software APIs feature full access to TJA1100 internal registers. This enables cable-testing and network diagnosis.

The design of the FC601 USB OABR Stick contains two main components. The NXP LPC4333 microcontroller features an USB 2.0 device interface for connectivity to a MS-Windows or Linux host platform. A NXP TJA1100 BroadR-Reach PHY is realizing the physical interface to an OABR network. The LPC4333 microcontroller and the TJA1100 PHY are connected via RMII, SMI and GPIO interface signals.

The firmware of the LPC4333 is implementing standard USB HID and CDC/ECM class profiles allowing access to the automotive Ethernet network data through USB HID and CDC class drivers on MS-Windows and Linux host platforms.
