XR22804IL56-F

Overview

The XR22804IL56-F is a Hi-Speed USB to 10/100 Ethernet bridge controller manufactured by MaxLinear. It integrates four UART channels and supports USB 2.0 High Speed (480 Mb/s) and Full Speed (12 Mb/s) data rates. The device operates within a voltage range of 4.4 V to 5.25 V, with a typical operating current of 185 mA. Designed for industrial environments, it functions between -40°C and +85°C. The component is housed in a QFN-56 package suitable for surface mount technology.

Feature Summary

• Integrates four independent UART channels for serial communication expansion
• Provides high-speed connectivity via USB 2.0 interface bridging to Ethernet
• Supports standard 10/100 Mbps Ethernet transmission protocols

Applications

• Industrial automation systems requiring serial-to-Ethernet conversion
• Remote monitoring devices utilizing USB host connections
• Embedded network gateways for IoT sensor integration

Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm pinout compatibility and electrical specifications. Confirm availability status as distribution channels may list discontinued or limited stock items. Ensure the source document matches the exact part number to avoid functional mismatches in final assembly.

Selection Notes

Select this component when four UART interfaces are required alongside Ethernet bridging capabilities. Compare against the XR22802 model if fewer serial ports are sufficient for the design. Verify that the QFN-56 footprint aligns with the PCB layout constraints and thermal management requirements of the target application environment.

Part Context

This component belongs to the XR2280x series of USB-to-Ethernet bridges. It shares architectural similarities with the XR22800, XR22801, and XR22802 models, differing primarily in the number of integrated UART channels. The series provides a standardized solution for converting USB signals to Ethernet traffic in embedded applications.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate the XR22802IL56-F for designs requiring fewer UART channels. Cross-reference with other USB-to-Ethernet controllers from different manufacturers only after verifying electrical and mechanical compatibility.
