XR20M1280IL24-F

Controllers Overview

The XR20M1280IL24-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, supporting standard logic levels of 1.8 V, 2.5 V, and 3.3 V. The device features a data rate capability of 24 Mb/s and includes 128 bytes of storage capacity. It draws a typical operating power current of 2.5 mA. Designed for surface-mount applications, it is housed in a QFN-24 package. The component functions reliably across an industrial temperature range from -40°C to +85°C.

Controllers Feature Summary

• Integrates I2C and SPI interfaces for digital control of the UART peripheral
• Includes built-in level shifters to accommodate varying voltage domains
• Provides four general-purpose input/output (GPIO) pins for system flexibility

Controllers Applications

• Embedded systems requiring serial communication via I2C or SPI masters
• Industrial automation controllers needing robust UART connectivity
• IoT devices with limited pin counts requiring protocol translation

Controllers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for End-of-Life notices or Production Change Notices. Ensure the specific suffix matches design requirements before procurement.

Controllers Selection Notes

Select this model when a single UART channel is sufficient alongside I2C/SPI control. The QFN-24 package suits space-constrained designs. Verify that the 24 Mb/s speed and 128-byte buffer meet application throughput needs. Consider thermal dissipation limits within the specified operating temperature range.

Controllers Part Context

This part belongs to the XR20M1280 series of I2C/SPI to UART converters. It shares functional similarities with other MaxLinear interface ICs but is distinct in its single-channel configuration and specific GPIO count. It serves as a bridge between digital controllers and legacy serial peripherals.

Controllers Replacement Considerations

Check for direct substitutes within the XR20M1280 family with different packages. Evaluate cross-references from other manufacturers offering similar I2C/SPI UART bridges with comparable voltage ranges and pinouts.
