XR22802IL56TR-F

Overview

The XR22802IL56TR-F is a USB interface integrated circuit manufactured by MaxLinear, functioning as a bridge between USB and Ethernet protocols. It supports Hi-Speed USB 2.0 standards with data rates of 12 Mb/s and 480 Mb/s. The device operates within a voltage range of 4.4 V to 5.25 V, consuming up to 185 mA of current. Designed for industrial environments, it functions between -40°C and +85°C. It utilizes a QFN-56 package and includes interfaces for EDGE, Ethernet, I2C, UART, and USB.

Feature Summary

• Integrates USB 2.0 High Speed connectivity with 10/100 Ethernet bridging capabilities
• Supports dual-channel UART communication alongside I2C and EDGE interfaces
• Operates reliably across extended industrial temperature ranges

Applications

• Industrial automation systems requiring serial-to-Ethernet conversion
• Embedded devices needing USB host or device connectivity with network access
• IoT gateways utilizing multiple serial and network protocols

Procurement Notes

Verify component authenticity through authorized channels due to potential supply chain variations. Confirm specific ordering suffixes match design requirements, as packaging formats like tape-and-reel may differ from tray versions. Check for recent product change notices or end-of-life notifications prior to final procurement decisions.

Selection Notes

Select this model when both high-speed USB and Ethernet bridging are required in a single component. Ensure the QFN-56 footprint fits the PCB layout constraints. Verify that the 5V power supply domain aligns with system voltage levels, as the device requires a minimum of 4.4 V for stable operation.

Part Context

This component belongs to the XR22802 series of USB controllers designed for bridging applications. It shares functional similarities with other models in the family but offers specific pin counts and interface combinations tailored for complex embedded networking tasks.

Replacement Considerations

The XR22802IL56-F is a related variant in the same series. Verify if tray packaging meets assembly needs instead of the TR-F reel format. Cross-reference datasheets to ensure pin compatibility and electrical specifications remain identical before substitution.
