XR16M654IL48TR-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The XR16M654IL48TR-F is a quad universal asynchronous receiver/transmitter (UART) interface integrated circuit manufactured by MaxLinear. It features four independent UART channels, each equipped with 64-byte transmit and receive FIFOs that support programmable trigger levels. The device supports data rates up to 16 Mb/s and operates within a supply voltage range of 1.62 V to 3.63 V, compatible with 1.8 V, 2.5 V, and 3.3 V systems. It includes automatic hardware and software flow control and supports both Intel and Motorola bus protocols. The component is housed in a QFN-48 package for surface-mount installation.

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix TR-F indicates tape-and-reel packaging when sourcing this component. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Check for end-of-life notifications as availability may be restricted. Ensure the QFN-48 footprint matches the design layout requirements.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this model when four independent UART channels are required in a compact form factor. The 64-byte FIFO depth helps manage data throughput efficiently at speeds up to 16 Mb/s. Verify that the operating voltage range of 1.62 V to 3.63 V aligns with the system power rails. Consider the QFN-48 package constraints for thermal management and PCB space.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the XR16M654 series of VLIO UARTs from MaxLinear. It shares functional similarities with other quad UART models like the XR16V654 but differs in supply voltage specifications and feature sets. The IL48 designation refers to the industrial temperature range and QFN-48 package type.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The XR16V654IL-F is a related quad UART model but operates on a different voltage range (2.25 V to 3.6 V). Verify compatibility if substituting, as the XR16M654 supports lower voltages down to 1.62 V. No direct pin-for-pin replacements are confirmed in public sources.
