XR28V384IM48-F

Overview

The XR28V384IM48-F is a quad Low Pin Count (LPC) Universal Asynchronous Receiver/Transmitter manufactured by MaxLinear. It integrates four independent UART channels, each equipped with a 128-byte transmit and receive FIFO buffer to enhance data throughput and reduce CPU overhead. The device operates on a single 3.3 V power supply within a voltage range of 2.97 V to 3.63 V. It supports asynchronous serial communication at data rates up to 3 Mb/s. The component functions reliably across an industrial temperature range from -40°C to +85°C and is housed in a 48-lead TQFP surface-mount package.

Feature Summary

• Integrates four independent LPC UART channels with dedicated 128-byte FIFO buffers for efficient data handling.

Applications

• Industrial automation systems requiring multiple serial connections
• Embedded control units with limited CPU resources
• Communication gateways utilizing LPC bus interfaces

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix matches the required package and temperature grade. Check for End-of-Life status or discontinuation notices prior to finalizing procurement plans to ensure long-term supply stability.

Selection Notes

Select this component when a design requires four distinct serial ports with substantial buffering capabilities. Ensure the system architecture supports the LPC UART protocol rather than standard RS-232 or RS-485 signaling without additional transceivers. Validate that the 48-pin TQFP footprint aligns with the PCB layout constraints.

Part Context

This part belongs to the XR28V384 series of quad LPC UARTs. It serves as a high-density serial interface solution for applications needing multiple asynchronous communication lines. The device simplifies board design by consolidating four UARTs into a single integrated circuit with built-in FIFO management.

Replacement Considerations

The XR28V384IM48-0A is listed as a similar part number in public documentation. Verify pin compatibility and electrical specifications before substitution. No other direct cross-references are confirmed in available sources.
