Overview for XChip Direct
Affordable Serial to Ethernet Connectivity in a Deployment-Ready Chip
A member of the DeviceLinx XChip family of networking system-on-chip solutions, the XChip Direct SoC rapidly delivers highly-affordable and field-proven Ethernet (IP) connectivity to virtually any electronic product with a serial interface on its host microcontroller. In designs where embedded web server capability is not required, XChip Direct delivers the SoC bundled with application and networking firmware for the same level of Ethernet connectivity as the market-proven XPort Direct device networking module.
Highly-integrated Networking Processor SoC
Fabricated using an industry-standard CMOS process, XChip Direct is a highly-integrated x86 class processor that includes a built in Ethernet MAC and 10-100 PHY, 256 KB zero wait-state SRAM, up to 2 GPIOs and a high-performance serial UART in a compact 12mm x 12mm 184 BGA RoHS-compliant, industrial temperature package.
Simply connect the serial port to the XChip Direct and load the Lantronix supplied royalty free standard application and network protocol firmware in an external Flash chip. Finish by adding an RJ45 jack and magnetics to instantly connect virtually any product to an Ethernet network or the Internet!
A dedicated networking co-processor, it enables the host microcontroller to function at maximum capacity without the burden of network processing overhead. Serial data from the device microcontroller’s CMOS logic-level serial port is packetized and delivered over an Ethernet network via TCP or UDP data packets Similarly, incoming TCP or UDP packets are packaged and sent to the attached device over its microcontroller’s serial interface. This enables OEMs to use less expensive, less powerful host microcontrollers on their products without sacrificing performance.
Feature-rich, Royalty-free Application and Network Protocol Firmware
XChip Direct comes with robust, licensed networking firmware so virtually zero programming is required. Powered by the same firmware already deployed in millions of networked nodes, this processor makes it easy to design-in connectivity and significantly speed time-to-market. The application-ready networking firmware and a feature-rich network protocol stack includes TCP/IP, UDP, BootP, DHCP and AutoIP.
It also features a variety of configurable options for serial-to- Ethernet tunneling (baud rate, flow control, port number, data packing control intervals, inactivity timeout and MTU size).
Ideal for High-Volume Applications
With its low cost, small size and potent functionality, XChip Direct is an ideal solution for high-volume, cost sensitive products.

Additional Software Utilities for Easy Configuration & Network Deployment
Deploying products in volume on a network typically require additional Windows software to simplify implementation. Dynamic Host Protocol Support (DHCP) and additional IP configuration methods included with XChip Direct’s Windows® –based DeviceInstaller software streamline device deployment and network initiation.
Additionally, the included Com Port Redirector (CPR) software maps “virtual COM” ports on a PC platform and redirects application data destined for an attached device. Rather than going out the local COM port, the data is transmitted across the Ethernet network to and from the XChip Direct using TCP/IP.
