XR16L2750IMTR-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The XR16L2750IMTR-F is a dual universal asynchronous receiver-transmitter (UART) interface integrated circuit manufactured by MaxLinear. It features two independent DUART channels with 64-byte transmit and receive FIFOs, supporting data rates up to 6.25 Mbps. The device operates on a supply voltage range of 2.25V to 5.5V and is housed in a 48-TQFP package. Key functional attributes include an internal oscillator, hardware flow control, IrDA encoding/decoding, false start bit detection, and modem control capabilities.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Dual UART architecture with 64-byte FIFO buffers for each channel
• Integrated IrDA encoder and decoder functionality
• Hardware automatic flow control and modem control signals

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial communication systems requiring RS-232 or RS-485 interfaces
• Embedded devices utilizing IrDA wireless connectivity
• Data acquisition modules needing high-speed serial transmission

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

This component is listed as obsolete or end-of-life. Verification of current availability requires checking authorized distributors for remaining stock or last-time buy notifications. Confirm the specific suffix 'TR' indicates tape-and-reel packaging when sourcing replacements. Ensure compatibility with existing PCB footprints before procurement.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this part for applications requiring dual-channel serial communication with moderate FIFO depth. Verify that the 48-TQFP package fits the design constraints. Consider the 6.25 Mbps maximum speed against system requirements. Check if the integrated IrDA feature is necessary, as it may not be needed for standard wired connections.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

The XR16L2750 series belongs to MaxLinear's portfolio of UART interface controllers. This specific model provides dual channels, distinguishing it from single-channel variants like the XR16L580. It serves as a bridge between parallel microprocessor buses and serial asynchronous data streams, commonly used in legacy and industrial embedded systems.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Verify pin-to-pin compatibility with other dual UART ICs from the same manufacturer. Cross-reference datasheets for electrical characteristics such as operating voltage and data rate. Ensure the replacement supports the required protocol standards (RS-232/RS-485/IrDA).
