XR16V2750IM-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The XR16V2750IM-F is a dual-channel UART interface controller manufactured by MaxLinear, Inc. It integrates two independent asynchronous serial communication channels within a single integrated circuit. The device features 64-byte FIFOs for each channel to enhance data throughput and reduce CPU overhead. It supports data rates up to 1 MBps and operates with a maximum clock frequency of 64 MHz. The component is housed in a 48-pin Thin Quad Flat Package (TQFP) with dimensions of 7 mm x 7 mm and a height of 1 mm. It functions as a Serial I/O Controller compatible with CMOS logic levels.

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the manufacturer designation carefully, as listings may attribute this part to Exar Corporation or MaxLinear due to corporate history. Confirm the package type is TQFP-48 and check RoHS compliance status. Ensure the specific suffix matches the required operational voltage range, noting that some variants support 2.5V supply at 50MHz. Cross-reference the datasheet version to confirm pinout compatibility before procurement.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when dual UART functionality with substantial buffering is required in a compact footprint. Compare against the XR16V2751 series if higher data rates or different packaging are needed. Verify that the 64-byte FIFO depth meets system latency requirements. Ensure the operating temperature range aligns with the application environment, typically -40°C to +85°C for industrial grades.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This component belongs to the XR16V275x family of dual UART controllers. It shares architectural similarities with other members like the XR16V2751 but differs in specific electrical characteristics and packaging options. The part is often associated with legacy Exar product lines now managed under MaxLinear. It serves as a bridge between parallel bus systems and serial communication peripherals.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Consider checking for direct pin-compatible alternatives within the same XR16V27xx family, such as the XR16V2751, after verifying electrical parameter compatibility.
