XR20M1280IL32-F

Overview

The XR20M1280IL32-F is a single-channel UART interface integrated circuit manufactured by MaxLinear. It operates within a supply voltage range of 1.62 V to 3.63 V, with typical operation at 1.8 V, 2.5 V, or 3.3 V. The device supports data rates up to 24 Mb/s and includes a 128-byte FIFO storage capacity. It features an I2C/SPI interface for configuration and control. The component is housed in a QFN-32 package suitable for surface mount technology. It functions across a temperature range from -40°C to +85°C and draws a typical operating current of 2.5 mA.

Feature Summary

• Integrates level shifters for flexible voltage domain interfacing
• Supports configurable I2C and SPI control interfaces
• Includes four general-purpose input/output pins

Applications

• Industrial automation systems requiring serial communication
• Embedded IoT devices needing low-power serial connectivity
• Test and measurement equipment utilizing high-speed UART links

Procurement Notes

Verify the specific suffix and package variant against the original design specification before procurement. Confirm that the I2C/SPI address settings match the system controller requirements. Check for moisture sensitivity labeling on packaging to ensure proper handling during assembly. Validate that the lead-free status meets environmental compliance standards for the target region.

Selection Notes

Select this component when a single UART channel with integrated level shifting is required. Ensure the host system supports either I2C or SPI for register configuration. Verify that the QFN-32 footprint aligns with the PCB layout constraints. Consider the 128-byte FIFO depth for buffer management needs in high-throughput applications.

Part Context

This part belongs to the XR20M1280 series of UARTs with integrated level shifters. It is designed to replace legacy UART components in modern low-voltage designs. The series offers industry-leading speed and flexibility through software-configurable interfaces. It serves as a bridge between low-voltage logic and higher-voltage serial peripherals.

Replacement Considerations

Check for direct pin-compatible alternatives within the same MaxLinear family. Verify if the XR20M1280IG24TR-F or other package variants meet the mechanical constraints. Ensure any substitute maintains the same I2C/SPI interface compatibility and FIFO size.
