XR22801IL32TR-F

Overview

The XR22801IL32TR-F is a USB interface integrated circuit manufactured by MaxLinear, Inc. It functions as a bridge converting High-Speed USB signals to Ethernet and includes one channel of UART interface. The device supports USB 2.0 standards with data rates of 12 Mb/s and 480 Mb/s. It operates within a supply voltage range of 4.4 V to 5.25 V and draws a typical operating current of 185 mA. The component is housed in a QFN-EP-32 package suitable for surface mount technology. It features an operating temperature range from -40°C to +85°C and includes humidity sensitivity protection.

Feature Summary

• Integrates Hi-Speed USB to 10/100 Ethernet bridging capabilities
• Includes a single channel UART interface for serial communication
• Supports USB 2.0 High Speed (480 Mb/s) and Full Speed (12 Mb/s) modes

Applications

• USB to Ethernet gateway devices
• Industrial control systems requiring serial-to-network conversion
• Embedded network interface modules

Procurement Notes

Verify the specific ordering suffix against official MaxLinear documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status through the manufacturer's latest product change notices or datasheet revision history. Ensure compatibility with system power requirements given the 185 mA operating current draw. Check for any active product discontinuation notifications or end-of-life declarations prior to finalizing procurement plans.

Selection Notes

Select this component when a combined USB host/device and Ethernet bridge function is required alongside a dedicated UART port. Compare pinout and electrical characteristics against similar models like the XR22802 if multiple UART channels are needed. Verify that the QFN-EP-32 footprint matches the PCB layout constraints. Ensure the design accommodates the specified 4.4 V to 5.25 V supply voltage range and thermal dissipation requirements for the target operating environment.

Part Context

This part belongs to the XR22801 series of USB interface controllers designed for networking applications. It is distinct from the XR22802, which offers two UART channels instead of one. The TR-F suffix typically indicates a tape-and-reel packaging format with specific environmental compliance attributes defined by the manufacturer. It serves as a specialized solution for integrating USB connectivity with Ethernet and serial interfaces in compact form factors.

Replacement Considerations

The XR22802IL56-F is a related model offering dual UART channels but utilizes a QFN-56 package, requiring significant PCB redesign. No direct pin-compatible replacements are identified in the provided data. Evaluate functional equivalence carefully as package dimensions and pin counts differ across the series.
