XR16M580IM48-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The XR16M580IM48-F is a single-channel Universal Asynchronous Receiver/Transmitter (UART) interface integrated circuit manufactured by MaxLinear. It features 16-byte transmit and receive FIFOs to enhance data throughput and reduce CPU overhead. The device supports multiple bus protocols, including Intel and Motorola interfaces, and operates within a supply voltage range of 2.25 V to 5.5 V. It is housed in a 48-pin TQFP package with a maximum data rate of 3.125 Mbps and functions across an industrial temperature range of -40°C to +85°C.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Supports Intel and Motorola bus protocol compatibility for flexible system integration.
• Includes integrated IrDA encoder and decoder capabilities for infrared communication applications.
• Features automatic hardware flow control to manage data transmission efficiency.

UARTs (Universal Asynchronous Receiver Transmitter) Applications

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

This component is designated as End-of-Life (EOL) by the manufacturer. Verification of current stock availability through authorized distributors is essential before design finalization. Engineers should review official Product Change Notifications (PCNs) and discontinuation notices to assess long-term supply risks and plan necessary lifecycle transitions.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this part when a single UART channel with moderate FIFO depth is required alongside specific bus protocol support. Verify that the 3.125 Mbps speed meets application timing constraints. Ensure the 48-TQFP footprint aligns with PCB layout capabilities. Consider power consumption specifications if battery-operated designs are involved.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

The XR16M580 belongs to the XR16L580 series of small UARTs. It shares architectural similarities with other devices in the family but is distinguished by its single-channel configuration and specific protocol support. This model serves as a specialized interface solution compared to dual-channel variants like the XR16M2650.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult MaxLinear technical support for validated pin-to-pin or functional replacements suitable for EOL transition strategies.
