XR21V1410IL16-F

Overview

The XR21V1410IL16-F is a single-channel Full-Speed USB to UART bridge integrated circuit manufactured by MaxLinear. It operates within a supply voltage range of 2.97 V to 3.63 V and supports data rates up to 12 Mb/s. The device features a 256-byte FIFO buffer to enhance throughput efficiency. It is housed in a compact QFN-16 package with dimensions of 3 x 3 x 0.88 mm. The component functions as a USB controller for serial communication applications.

Feature Summary

• Integrates a 256-byte FIFO buffer for efficient data handling
• Supports Full-Speed USB 2.0 interface standards
• Provides single-channel UART bridging functionality

Applications

• USB to UART interface conversion systems
• Industrial serial communication bridges
• Embedded device connectivity solutions

Procurement Notes

Verify the manufacturer designation, as historical documentation may reference Exar Corporation prior to acquisition by MaxLinear. Confirm the specific suffix indicates the tray packaging variant rather than tape-and-reel. Ensure compatibility with required operating temperature ranges spanning -40 °C to +85 °C for industrial deployment.

Selection Notes

Select this component when a single UART channel is sufficient for the design requirements. Compare against the XR21V1414 series if multiple channels are needed. Verify that the QFN-16 footprint aligns with the PCB layout constraints. Ensure the host system supports Full-Speed USB enumeration protocols.

Part Context

This part belongs to the XR21V141x family of Full-Speed USB UART controllers. It serves as the single-channel variant within the lineup, distinct from multi-channel options like the XR21V1414. The device replaces legacy UART interfaces with modern USB connectivity while maintaining standard serial protocol compatibility.
