XR20M1280IL32TR-F

Overview

The XR20M1280IL32TR-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 a 128-byte FIFO storage capacity. It is housed in a QFN-32 package suitable for surface mount technology. The component functions as an I2C/SPI to UART bridge, allowing serial communication conversion. It supports an operating temperature range from -40°C to +85°C and draws a typical operating current of 2.5 mA.

Feature Summary

• Integrates I2C or SPI master interfaces with UART functionality for protocol bridging
• Includes built-in level shifters to support multiple voltage domains
• Provides four general-purpose input/output pins for system control

Applications

• Embedded systems requiring I2C or SPI to UART translation
• Industrial automation controllers
• IoT gateway devices

Procurement Notes

Verify the specific suffix TR-F indicates tape and reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the supplier provides valid traceability records for this discontinued series component.

Selection Notes

Select this part when a single UART channel with high-speed 24 Mb/s performance is required alongside I2C or SPI connectivity. The 128-byte FIFO helps manage data throughput efficiently. Verify that the QFN-32 footprint matches the target PCB layout constraints.
