XR16V554IL

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The XR16V554IL is a quad universal asynchronous receiver/transmitter (UART) interface integrated circuit manufactured by MaxLinear. It features four independent UART channels, each equipped with 16-byte transmit and receive FIFOs to enhance data throughput and reduce CPU overhead. The device supports data rates up to 4 Mb/s and operates within a supply voltage range of 2.25 V to 3.6 V. It is designed for industrial applications, functioning reliably at temperatures from -40°C to +85°C. The component utilizes an LQFP-64 surface-mount package and includes Intel bus compatibility.

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the manufacturer designation carefully, as the part number indicates MaxLinear production despite the historical Sipex branding. Confirm the specific suffix requirements for temperature grade and packaging format against current official datasheets before procurement to ensure compatibility with design specifications.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when multiple independent serial ports are required in a compact form factor. Ensure the host system voltage aligns with the 2.25 V to 3.6 V operating range. Consider the LQFP-64 package constraints for PCB layout and thermal management during the design phase.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This component belongs to the XR16V554D series of quad UARTs. It represents a continuation of technology originally developed by Sipex, now produced under MaxLinear. The series is characterized by its multi-channel capability and FIFO buffering, distinguishing it from single-channel UART solutions.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Cross-reference with other XR16V554 variants such as XR16V554CI or XR16V554DI to match specific temperature ranges and package types. Verify pinout compatibility and electrical characteristics before substituting.
