XR21V1410IL16MTR-F

Overview

The XR21V1410IL16MTR-F is a single-channel Full-Speed USB to UART bridge controller 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 compliant with USB 2.0 standards. The device integrates a 256-byte transmit FIFO and a 384-byte receive FIFO to manage data buffering efficiently. It is housed in a 16-pin VFQFN package with an exposed pad, measuring 3 mm by 3 mm with a 0.5 mm pitch. The component functions as a CMOS interface solution for converting USB signals to serial UART communications.

Feature Summary

• Integrates dedicated transmit and receive FIFO buffers for efficient data handling
• Provides direct conversion between USB 2.0 Full-Speed and UART protocols
• Utilizes a compact surface-mount QFN package design

Applications

• USB to Serial UART interface development
• Embedded system connectivity solutions
• Industrial communication bridge implementations

Procurement Notes

Verify the specific suffix 'MTR-F' against official MaxLinear documentation to confirm tape-and-reel packaging and exact electrical characteristics. Ensure compatibility with the required operating voltage range of 2.97 V to 3.63 V for your target application. Cross-reference the part number with current distributor listings to confirm availability and lead times, as supply chain conditions may vary. Confirm RoHS compliance status through the manufacturer's latest environmental declarations before finalizing procurement orders.

Selection Notes

Select this component when a single-port USB to UART bridge is required with integrated FIFO buffering. It is suitable for applications needing Full-Speed USB 2.0 connectivity at 12 Mb/s. Consider the 16-QFN package size for space-constrained designs. Verify that the 3.3 V nominal operating voltage aligns with your system power rails. This part serves as a direct replacement for legacy Exar-branded units within the same family.
