XR20V2172IL64-F

Overview

The XR20V2172IL64-F is a dual-channel Universal Asynchronous Receiver/Transmitter (UART) interface integrated circuit manufactured by MaxLinear. It operates within a voltage range of 1.62 V to 3.63 V and supports data rates up to 16 Mb/s. The device features 64-byte transmit and receive FIFOs for each channel, reducing host processor intervention. It interfaces with the host system via I2C or SPI protocols and functions within an operating temperature range of -40 °C to +85 °C. The component is housed in a TSSOP-28 package.

Feature Summary

• Dual independent UART channels with dedicated 64-byte FIFOs per channel
• Supports both I2C and SPI host interface protocols
• Operates on low supply voltages ranging from 1.62 V to 3.63 V
• Includes programmable baud rate generators and standard UART control signals

Applications

• Industrial automation systems requiring serial communication
• Embedded IoT devices with limited GPIO resources
• Medical equipment utilizing serial data transmission
• Automotive infotainment and control modules

Procurement Notes

Verify the specific suffix 'IL64' confirms the TSSOP-28 package and industrial temperature grade during procurement. Confirm that the manufacturer designation aligns with current MaxLinear product lines following corporate restructuring. Ensure compatibility with existing I2C or SPI bus configurations before ordering.

Selection Notes

Select this component when a design requires two isolated serial ports controlled by a single microcontroller via a serial bus. It serves as a suitable alternative to parallel UART controllers where pin count reduction is critical. Consider the 64-byte FIFO depth for buffering requirements against potential bus latency issues in the target application environment.

Part Context

This part belongs to the XR20V217x family of serial interface controllers designed to bridge high-speed system buses to legacy asynchronous serial standards. The series emphasizes low power consumption and small form factors for space-constrained embedded applications. It replaces older discrete UART solutions by integrating logic and memory into a single compact package.

Replacement Considerations

Direct replacements include the XR20M1172 for similar dual-channel I2C/SPI UART functionality. Verify pinout compatibility and FIFO depths when substituting with other MaxLinear serial bridge components.
