XR16V2550ILTR-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The XR16V2550ILTR-F is a dual UART interface integrated circuit manufactured by MaxLinear. It features two independent channels with 16-byte transmit and receive FIFOs, supporting data rates up to 4 Mbps. The device operates on a supply voltage range of 2.25 V to 5.5 V and is housed in a 32-lead QFN package (5 mm x 5 mm). It supports RS-232, RS-422, and IrDA protocols, includes an internal oscillator, and offers automatic flow control capabilities.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Dual UART architecture with dedicated 16-byte FIFOs for each channel to reduce CPU overhead.
• Supports multiple communication protocols including RS-232, RS-422, and IrDA encoder/decoder integration.
• Integrated internal oscillator eliminates the need for external clock components.
• Hardware automatic flow control functionality ensures reliable data transmission.

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial automation systems requiring serial communication interfaces.
• Embedded devices needing compact dual-port serial connectivity.
• Point-of-sale terminals and payment systems utilizing RS-232 or RS-422 standards.
• Medical equipment requiring reliable serial data transfer in space-constrained designs.

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix 'ILTR' confirms the tape-and-reel packaging format and industrial temperature grade during sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor certificates before procurement. Ensure the supplier provides traceability data consistent with MaxLinear quality standards.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a design requires two independent serial ports within a small footprint. Compare against single-channel alternatives if only one port is needed to optimize cost. Verify that the 32-QFN package dimensions fit the PCB layout constraints. Ensure the operating voltage range matches the system power rails.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the XR16L/V/C series of low-power UARTs from MaxLinear. It shares functional similarities with the XR16L2550 but differs in package type and specific electrical characteristics. The series is designed for applications demanding high integration and low power consumption in serial communication tasks.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The XR16L2550IM-F is a pin-compatible alternative in a TQFP package. The XR16V2551ILTR-F offers similar functionality with potential minor parameter variations. Verify pinout compatibility and electrical specifications before substitution.
