XR20V2170IL40-F

Overview

The XR20V2170IL40-F is a quad-channel Universal Asynchronous Receiver/Transmitter (UART) interface integrated circuit manufactured by MaxLinear. It provides four independent UART channels within a single package, designed for applications requiring multiple serial communication ports. The device operates with a supply voltage range of 3.0 V to 5.5 V and supports data rates up to 3 Mbps per channel. It features programmable baud rate generators, 16-byte transmit and receive FIFOs, and hardware flow control support. The component is housed in a 40-lead QFN package suitable for space-constrained designs.

Feature Summary

• Integrates four independent UART channels for multi-port serial connectivity
• Supports high-speed data transmission up to 3 Mbps per channel
• Includes 16-byte TX and RX FIFOs to enhance system throughput
• Provides hardware flow control capabilities for reliable data transfer

Applications

• Industrial automation systems requiring multiple sensor interfaces
• Telecommunications equipment with multi-port serial requirements
• Embedded computing platforms needing expanded serial connectivity
• Medical devices utilizing multiple diagnostic data streams

Procurement Notes

Verify the specific suffix and package variant when sourcing, as MaxLinear may offer different pin configurations or temperature grades within the XR20V2170 family. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure compatibility with existing PCB footprint designs, particularly regarding the 40-lead QFN thermal pad requirements for proper heat dissipation during operation.

Selection Notes

Select this component when a design requires four distinct UART interfaces without consuming multiple IC footprints. Consider the 3 Mbps maximum baud rate against application timing requirements. Evaluate the 16-byte FIFO depth relative to expected data burst sizes to prevent overflow. Verify that the operating voltage range aligns with the target system power rails, noting the 3.0 V to 5.5 V operational window.

Part Context

The XR20V2170 belongs to MaxLinear's Exar UART product line, which focuses on providing compact, high-performance serial interface solutions. This quad-channel variant addresses the need for dense serial connectivity in modern embedded systems. It complements other members of the XR20V217x family, which may offer different channel counts or package options, allowing designers to scale serial port availability based on specific project constraints.

Replacement Considerations

Direct replacements within the same family include other XR20V2170 variants with differing suffixes indicating package or temperature variations. Cross-family alternatives from other manufacturers require careful verification of pinout compatibility, electrical specifications, and register-level software compatibility before substitution.
