XR19L220IL40-F

Overview

The XR19L220IL40-F is a dual-channel UART interface integrated circuit manufactured by MaxLinear. It features two independent UART channels, each equipped with a 64-byte transmit and receive FIFO buffer to enhance data throughput and reduce CPU overhead. The device supports data rates up to 8 Mb/s and operates within a supply voltage range of 2.97 V to 5.5 V, compatible with 3.3 V and 5 V systems. It is housed in a 40-lead QFN package and functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

Dual independent UART channels with dedicated 64-byte FIFO buffers for efficient data handling.

Applications

Industrial automation control systems requiring multiple serial connections.

Procurement Notes

Verify the specific suffix and manufacturer designation against current MaxLinear documentation, as component availability and lifecycle status may vary. Confirm RoHS compliance and moisture sensitivity levels prior to integration into production assemblies.

Selection Notes

Select this component when a design requires two isolated UART interfaces with substantial buffering capabilities in a compact footprint. Ensure the host system voltage aligns with the specified 2.97 V to 5.5 V operating range and that the thermal environment remains within the -40°C to +85°C specification.

Part Context

This part belongs to the XR19L series of combo UARTs from MaxLinear, designed for applications needing high-performance serial communication. It serves as a bridge between parallel processor buses and serial peripheral devices, offering a compact solution for multi-port serial connectivity in embedded systems.
