XR21V1412IL32-F

Overview

The XR21V1412IL32-F is a single-port 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 draws a typical operating current of 15 mA. The device supports data rates up to 12 Mb/s in compliance with USB 2.0 standards. It features 512-byte transmit and receive FIFOs to enhance throughput efficiency. The component is housed in a QFN-32 surface-mount package and functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Integrates dual-channel UART functionality with independent programmable baud rates and control signals for each port.
• Includes built-in hardware flow control logic to manage data transmission without CPU intervention.
• Supports direct connection to RS-232 transceivers via internal voltage regulators, reducing external component count.

Applications

• Industrial automation systems requiring robust serial communication interfaces.
• Medical equipment utilizing USB connectivity for diagnostic data transfer.
• Point-of-sale terminals needing reliable serial peripheral integration.

Procurement Notes

Verify the specific suffix against official MaxLinear documentation to confirm pinout compatibility and electrical characteristics. Ensure that the QFN-32 package dimensions align with your PCB footprint requirements. Confirm RoHS compliance status through the manufacturer's latest certification records before finalizing procurement decisions.

Selection Notes

Select this component when dual UART ports are required within a compact form factor. Compare FIFO depths against application buffer needs to determine if higher-capacity variants are necessary. Evaluate power consumption constraints to ensure the 15 mA operating current fits within the system's thermal budget.

Part Context

This part belongs to the XR21V141x family of Full-Speed USB UART controllers. It shares architectural similarities with the XR21V1410 and XR21V1414 models but offers distinct pin configurations and channel counts. The series is designed for applications replacing legacy UART-to-USB adapters with integrated solutions.

Replacement Considerations

Check for XR21V1412IL32-F equivalents from authorized distributors. Verify pin-to-pin compatibility with existing designs before substitution. Consult MaxLinear for any updated revisions or recommended alternative parts within the same product line.
