XR16V2550IL-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The XR16V2550IL-F is a dual Universal Asynchronous Receiver/Transmitter (UART) interface integrated circuit manufactured by MaxLinear. It features two independent channels, each equipped with a 16-byte transmit and receive FIFO buffer 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 5.5 V, compatible with 2.5 V, 3.3 V, and 5 V logic levels. It is housed in a QFN-32 surface-mount package and functions reliably across an industrial temperature range from -40°C to +85°C.

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix and manufacturer designation during sourcing, as component lineage may involve transitions between Exar and MaxLinear. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the QFN-32 package footprint matches your PCB design constraints before finalizing procurement decisions.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a dual UART solution with moderate FIFO depth is required. Compare against the XR16L2550 series if Intel bus compatibility is critical, or consider the XR16V654 for higher channel counts and larger FIFO capacities. Verify that the 4 Mb/s maximum data rate meets your application's bandwidth requirements.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the XR16V2550 family of VLIO UARTs. It shares functional similarities with other dual UART devices like the XR16L2550 but differs in specific bus compatibility and packaging options. The device is designed for general-purpose serial I/O expansion in compact electronic designs.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Direct substitutes include the XR16L2550IL-F for similar dual UART functionality with potential bus compatibility differences. For quad-channel needs, the XR16V554IL-F offers four channels with identical 16-byte FIFO structures.
