XR19L400IL40-F

Overview

The XR19L400IL40-F is a MaxLinear integrated UART and RS-485 transceiver featuring one transmit and one receive channel. It supports data rates up to 8 Mb/s with a 64-byte storage capacity. The device operates on supply voltages between 2.97 V and 5.5 V, drawing 20 mA or 40 mA depending on configuration. It functions within an industrial temperature range of -40°C to +85°C. Packaged in a QFN-40 format for surface mount installation, this component combines serial interface capabilities with robust transceiver performance.

Feature Summary

Integrates UART controller and RS-485 transceiver functionality into a single chip
Supports high-speed data transmission up to 8 Mb/s
Includes 64-byte buffer memory for efficient data handling
Operates reliably across extended industrial temperature ranges

Applications

Industrial automation control systems
Building management and security networks
Metering and utility infrastructure communication

Procurement Notes

Verify current availability status as the component may be discontinued. Confirm package integrity and moisture sensitivity level requirements before assembly. Ensure compatibility with existing design specifications regarding voltage levels and pin configurations. Consult official documentation for handling precautions.

Selection Notes

Select this component when a combined UART and RS-485 solution is required in a compact form factor. Consider the 64-byte FIFO depth for buffering needs. Verify that the operating voltage range matches the system power supply. Check if the QFN-40 package fits the board layout constraints.

Part Context

This part belongs to the XR19L400 series of combo UARTs manufactured by MaxLinear. It serves as a specialized interface solution bridging microprocessor UARTs with RS-485 physical layers. The series targets applications requiring reliable serial communication in noisy environments.

Replacement Considerations

Check for direct substitutes within the XR19L400 family. Evaluate other MaxLinear UART/RS-485 combinations based on pinout compatibility and electrical specifications.
