XR16C850IMTR-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The XR16C850IMTR-F is a single-channel Universal Asynchronous Receiver/Transmitter (UART) interface integrated circuit manufactured by MaxLinear. It features 128-byte transmit and receive FIFOs with counters to enhance data loading and unloading from the controlling CPU. The device supports data rates up to 2.25 Mb/s and operates on supply voltages of 3.3 V or 5 V, with a maximum rating of 5.5 V and minimum of 2.97 V. It is housed in an LQFP-48 surface-mount package and functions within an industrial temperature range of -40°C to +85°C.

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for End-of-Life notifications prior to procurement. Ensure storage conditions account for moisture sensitivity levels specified in the datasheet to prevent damage during assembly.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a single UART channel with large FIFO buffers is required for high-throughput applications. Compare against the XR16C854 series if multiple channels are needed. Verify that the LQFP-48 package footprint matches the PCB design constraints and that the operating voltage aligns with the target system power rails.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the XR16C850 series of enhanced UARTs designed for robust serial communication. It serves as a bridge between parallel processor buses and serial data streams, offering improved performance over legacy 16550-compatible devices through its deep buffering capabilities and higher speed support.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Check for pin-compatible alternatives such as the XR16C850CM-F or other MaxLinear VLIO UART variants. Ensure substitute parts maintain identical FIFO depths and voltage specifications to guarantee functional equivalence without redesigning the host interface.
