XR16V554IJTR-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The XR16V554IJTR-F is a quad universal asynchronous receiver/transmitter (UART) interface integrated circuit manufactured by MaxLinear. It operates within a supply voltage range of 2.25 V to 3.6 V and supports data rates up to 4 Mb/s. The device features 16-byte transmit and receive FIFOs for each channel. It is housed in a 68-pin PLCC package and is designed for surface-mount installation. The component functions as a serial I/O controller compatible with RS-232 standards.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Integrates four independent UART channels with dedicated 16-byte FIFO buffers for both transmission and reception to manage data flow efficiently.
• Supports high-speed serial communication with maximum data rates reaching 4 Mb/s across all channels.
• Operates on a single low-voltage power supply ranging from 2.25 V to 3.6 V, suitable for various digital logic families.

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial control systems requiring multiple serial communication ports
• Embedded devices needing RS-232 interface expansion
• Data acquisition systems utilizing serial I/O controllers

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific ordering suffix and package type against the manufacturer's current datasheet before procurement. Confirm that the 68-pin PLCC form factor matches the target PCB footprint. Check for any recent product change notices or discontinuation notifications from MaxLinear to ensure long-term availability and compliance with project lifecycle requirements.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a design requires four distinct UART interfaces within a single IC. Ensure the system power supply remains stable between 2.25 V and 3.6 V. Verify that the 68-pin PLCC package is compatible with the assembly process and that the 4 Mb/s data rate meets the application's throughput needs compared to lower-speed alternatives.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the XR16V554 series of quad UARTs from MaxLinear. It shares functional similarities with other members like the XR16V554IL-F but differs in package configuration. The series is characterized by low-voltage operation and integrated FIFOs, distinguishing it from older standard UARTs without buffering capabilities.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Potential substitutes include the XR16V554IL-F, which offers identical electrical specifications but utilizes a 48-QFN package instead of PLCC. Cross-reference pinouts carefully to ensure compatibility with existing board layouts if substituting packages.
