UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

This component is officially classified as End-of-Life (EOL) by the manufacturer. Availability is restricted to remaining stock from authorized distributors or third-party suppliers. Buyers should verify lot dates and authenticity carefully due to the discontinued status. Long-term production plans should consider alternative components to ensure supply chain stability.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this part when dual high-performance UARTs with deep FIFOs are required in a compact TQFP package. Ensure the design supports 2.5V, 3.3V, or 5V logic levels. Verify that the 6.25 Mb/s maximum baud rate meets system requirements. Consider the EOL status and plan for potential obsolescence management strategies during the product lifecycle.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

The XR16L2751 series belongs to MaxLinear's VLIO UART family, designed for general-purpose serial communication. The IMTR-F suffix indicates a specific tape-and-reel packaging variant within the industrial temperature range. This model serves as a successor to earlier Exar UART designs, maintaining pin compatibility while offering enhanced performance features like larger FIFOs.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Direct pin-to-pin replacements may include other dual UART ICs with similar FIFO depths and voltage ranges. Verify electrical specifications such as max baud rate and operating voltage before substitution. Consult MaxLinear documentation for recommended cross-reference parts or newer generations within the VLIO portfolio.
