XR21V1410IL16TR-F

Overview

The XR21V1410IL16TR-F is a single-channel Full-Speed USB to UART bridge integrated circuit manufactured by MaxLinear. It operates within a voltage range of 2.97 V to 3.63 V and supports data rates up to 12 Mb/s compliant with USB 2.0 standards. The device features a 256-byte transmit FIFO and a 384-byte receive buffer to manage data flow efficiently. Designed for surface-mount applications, it is housed in a compact QFN-16 package. The component functions reliably across an industrial temperature range from -40°C to +85°C, drawing approximately 16 mA during operation.

Feature Summary

• Integrates a single channel of USB connectivity with asynchronous UART interface capabilities
• Includes dedicated hardware flow control support for reliable data transmission management
• Utilizes small form-factor QFN packaging suitable for space-constrained board designs

Applications

• Industrial automation systems requiring serial communication over USB
• Embedded devices needing USB-to-UART bridging for configuration and debugging
• IoT gateways connecting legacy serial peripherals to host computers

Procurement Notes

Verify the specific suffix against official MaxLinear documentation to confirm pinout compatibility and electrical characteristics. Ensure the ordering code matches the required tape-and-reel quantity specifications. Cross-reference the manufacturer part number with authorized distributor listings to validate authenticity and current availability status before finalizing procurement orders.

Selection Notes

Select this component when a single-port USB-to-UART solution is required with moderate FIFO depths. Compare against the XR21B1411 if higher voltage tolerance or different FIFO sizes are needed. Consider the XR21V1414 for applications requiring additional I2C interfaces or multiple ports. Evaluate power consumption requirements against the specified 16 mA operating current.

Part Context

This part belongs to the XR21V141x family of Full-Speed USB UART controllers. It serves as a direct replacement for older Exar XR21V1410 variants. The series provides a drop-in compatible upgrade path for existing designs utilizing legacy USB serial bridges while offering improved integration and reduced footprint through modern packaging technologies.

Replacement Considerations

The XR21V1410IL16-F is the tray-packaged equivalent of this reel-delivered component. Verify that any substitute parts maintain identical pin assignments and electrical parameters to ensure mechanical and functional compatibility without requiring schematic modifications.
