XR16L2550ILTR-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The XR16L2550ILTR-F is a dual UART interface integrated circuit manufactured by MaxLinear. It features two independent channels, each equipped with a 16-byte transmit and receive FIFO buffer to enhance data throughput and reduce CPU overhead. The device supports data rates up to 4 Mb/s and operates within a supply voltage range of 2.25 V to 5.5 V, compatible with 2.5 V, 3.3 V, and 5 V systems. It is housed in a 32-pin QFN package (5x5 mm) designed for surface-mount technology. The component includes an internal oscillator, IrDA encoder/decoder, and automatic flow control capabilities.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Dual UART architecture with independent 16-byte Tx/Rx FIFOs per channel
• Integrated IrDA encoder and decoder for infrared communication support
• Automatic hardware flow control and modem signal management
• Internal clock oscillator eliminating the need for external crystals

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial automation systems requiring reliable serial communication
• Embedded devices needing multiple asynchronous serial ports
• Infrared data transmission modules utilizing IrDA protocols
• Telecommunications equipment interfaces

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and moisture sensitivity level handling requirements prior to assembly. Check for product discontinuation notices or lifecycle changes as availability may be restricted. Ensure packaging specifications match design requirements for surface-mount placement processes.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when dual-channel serial connectivity with moderate data rates is required. The 16-byte FIFO depth balances performance and memory usage for standard embedded applications. Verify that the 32-QFN package dimensions fit the PCB layout constraints. Consider power consumption profiles across different operating voltages if battery life is a critical design factor.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the XR16L2550 series of VLIO UARTs from MaxLinear. It is functionally similar to the XR16L2550IL but differs in packaging format, being supplied in tape-and-reel configuration rather than trays. It shares core specifications with other variants like the XR16L2550IM-F, differing primarily in package type and pinout compatibility.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Direct substitutes include the XR16L2550IL for tray-packaged equivalents. For single-channel needs, consider the XR16L580 series. Cross-reference pinouts carefully when replacing with older Exar-branded versions to ensure compatibility.
