XR16L2450IM-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The XR16L2450IM-F is a dual Universal Asynchronous Receiver/Transmitter (UART) interface integrated circuit manufactured by MaxLinear. It operates within a supply voltage range of 2.5 V to 5.5 V and supports data rates up to 4 Mb/s. The device features 16-byte transmit and receive FIFOs for each channel, enhancing throughput efficiency. It is housed in a TQFP-48 surface-mount package and functions reliably across an industrial temperature range from -40°C to +85°C. The component integrates standard UART control signals and supports multiple bus protocols.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Dual-channel architecture providing independent serial communication paths
• Integrated 16-byte FIFO buffers to reduce CPU intervention
• Support for Intel and Motorola bus interfaces

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial automation systems requiring robust serial connectivity
• Embedded controllers needing multiple asynchronous communication ports
• Data acquisition equipment with moderate baud rate requirements

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix 'IM' against official MaxLinear documentation to confirm the exact package type and temperature grade. Confirm RoHS compliance status through the manufacturer's current product change notices or datasheet revision history before finalizing procurement plans.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when two independent UART channels are required within a single footprint. Ensure the application environment stays within the specified -40°C to +85°C operating range. Verify that the 16-byte FIFO depth meets the system's latency requirements compared to larger buffer alternatives.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the XR16L2xxx series of high-performance UARTs. It shares functional similarities with other members like the XR16L2550 but differs in pinout compatibility and specific electrical characteristics defined by the 'IM' suffix designation within the MaxLinear portfolio.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Check for direct pin-compatible substitutes such as the XR16L2550IM if higher performance is needed. Verify electrical parameter overlaps carefully before substituting with older Exar-branded equivalents.
