XR16V2750IMTR-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The XR16V2750IMTR-F is a dual Universal Asynchronous Receiver/Transmitter (UART) integrated circuit manufactured by MaxLinear. It features two independent UART channels, each equipped with a 64-byte transmit and receive FIFO buffer to enhance data throughput and reduce CPU overhead. The device supports standard asynchronous serial communication protocols and operates within a supply voltage range of 3.0 V to 3.6 V. It is housed in a 48-lead Thin Quad Flat Package (TQFP) with a 7 mm x 7 mm body size. The component is designed for industrial applications, supporting an operating temperature range from -40°C to +85°C.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Dual-channel architecture providing two independent UART interfaces with dedicated 64-byte FIFOs per channel.
• Supports standard asynchronous serial communication protocols including RS-232, RS-422, and RS-485 signaling options.
• Integrated hardware flow control management to ensure reliable data transmission without software intervention.

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial automation systems requiring multiple serial communication ports.
• Embedded controllers needing high-throughput serial data handling via FIFO buffers.
• Telecommunications equipment utilizing standard asynchronous interfaces.

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific ordering suffix and package variant against current MaxLinear documentation, as the IMTR-F designation indicates a tape-and-reel packaging format. Confirm RoHS compliance status and moisture sensitivity level prior to procurement. Check for any product discontinuation notices or end-of-life notifications issued by the manufacturer, as availability may be restricted. Ensure the selected variant matches the required thermal and electrical specifications for the target application environment.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a design requires two independent UART interfaces with substantial buffering capabilities. The 64-byte FIFO depth is suitable for applications with bursty data traffic or varying baud rates. Verify that the system power supply aligns with the 3.0 V to 3.6 V operating range. Consider the TQFP-48 package dimensions for PCB layout constraints. Compare against single-channel alternatives if only one interface is needed, or higher-density multi-port devices if more than two channels are required.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

The XR16V2750 series belongs to MaxLinear's portfolio of high-performance UART interface controllers. These devices are engineered to replace legacy UART components while offering improved performance through larger FIFO depths and lower power consumption. The IMTR-F suffix specifically denotes the commercial temperature grade and reel packaging, distinguishing it from tray-packaged or extended temperature variants within the same functional family.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Direct pin-to-pin replacements within the same family include the XR16V2750IM (tray package). For designs requiring different FIFO sizes, consider the XR16V2550 series (16-byte FIFO) or XR16V2751 series (single channel). Verify compatibility with existing firmware drivers, as register maps may vary between generations.
