XR19L400IL40TR-F

Overview

The XR19L400IL40TR-F is a MaxLinear integrated UART and RS-485 transceiver featuring one channel with one transmitter and one receiver. It supports data rates up to 8 Mb/s and includes a 64-byte storage capacity. The device operates within a supply voltage range of 2.97 V to 5.5 V, with typical operating voltages at 3.3 V and 5 V. Power consumption varies between 20 mA and 40 mA depending on the configuration. It functions reliably in temperatures from -40°C to +85°C and is housed in a QFN-40 package for surface mount installation.

Feature Summary

Combines UART controller logic with an RS-485 transceiver in a single integrated circuit
Provides high-speed serial communication capabilities up to 8 Mb/s
Includes substantial internal buffering to manage data flow efficiently

Applications

Industrial automation systems requiring robust serial communication
Building automation and control networks
Embedded devices needing compact UART-to-RS-485 conversion

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance details via official documentation before integration. Check for moisture sensitivity handling requirements during storage and assembly processes to ensure long-term reliability.

Selection Notes

Select this component when a combined UART and RS-485 solution is required in a small form factor. Ensure the system voltage aligns with the 2.97 V to 5.5 V operating range. Consider the QFN-40 package constraints for PCB layout and thermal management during design.

Part Context

This part belongs to the XR19L400 series of combo UARTs manufactured by MaxLinear. It is designed for applications requiring space-saving solutions that integrate both protocol handling and physical layer transmission. The series targets industrial and commercial markets demanding reliable serial connectivity.

Replacement Considerations

The product lifecycle status is listed as End of Life. Engineers should evaluate alternative interface ICs from current MaxLinear portfolios or other manufacturers offering similar UART and RS-485 integration in compatible packages.
