XR28V384IM48TR-F

Overview

The XR28V384IM48TR-F is a quad Low Pin Count (LPC) Universal Asynchronous Receiver/Transmitter manufactured by MaxLinear. It integrates four independent UART channels within a single TQFP-48 package, designed for serial communication applications requiring multiple asynchronous ports. The device operates on a 3.3 V power supply with a voltage range of 2.97 V to 3.63 V and supports data rates up to 3 Mb/s. Each channel includes a 128-byte FIFO buffer to enhance throughput and reduce CPU overhead. The component functions within an industrial temperature range of -40°C to +85°C and draws 17 mA during operation.

Feature Summary

• Integrates four independent LPC UART channels in a compact surface-mount package
• Includes 128-byte FIFO buffers per channel to manage data flow efficiently
• Supports high-speed asynchronous serial communication up to 3 Mb/s
• Operates reliably across extended industrial temperature ranges

Applications

• Industrial automation systems requiring multiple serial connections
• Embedded control units with limited pin count constraints
• Telecommunications equipment utilizing LPC interface standards
• Multi-port serial monitoring and data logging devices

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for moisture sensitivity labeling prior to soldering. Review the latest Product Discontinuation Notification as availability may be restricted. Ensure storage conditions meet specified humidity requirements to prevent damage before reflow processes.

Selection Notes

Select this component when a design requires four distinct UART interfaces without consuming excessive PCB area. Compare against dual-channel alternatives if fewer ports are sufficient to optimize cost. Verify that the TQFP-48 footprint aligns with existing board layouts. Ensure the host system can support the 3.3 V logic levels and current consumption specifications under all operating conditions.

Part Context

This part belongs to the XR28V384 series of LPC UARTs from MaxLinear. It shares functional similarities with other multi-channel UARTs but distinguishes itself through its specific quad-channel configuration and integrated FIFO architecture. The series targets applications needing robust serial connectivity in space-constrained environments.

Replacement Considerations

Check for direct substitutes within the XR28V38x family. Evaluate alternative quad UART ICs from other manufacturers if lead times are critical. Ensure pin compatibility and register mapping alignment to minimize redesign efforts during transition.
