XR16C2850IJTR-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The XR16C2850IJTR-F is a dual universal asynchronous receiver and transmitter (DUART) manufactured by MaxLinear, Inc. It integrates two independent UART channels within a single integrated circuit. Each channel features a 128-byte transmit and receive FIFO buffer to enhance data throughput and reduce CPU intervention. The device supports serial communication protocols including RS-232 and RS-485 with a maximum data rate of 6.25 Mbps. It operates on a supply voltage range of 2.97 V to 5.5 V and utilizes an internal oscillator. The component is housed in a 44-pin Plastic Quad Flat Package (PQCC) or PLCC variant, designed for surface-mount assembly.

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific package suffix against the manufacturer's current datasheet, as 'TR' typically indicates tape-and-reel packaging while 'IJ' denotes the plastic quad flat package. Confirm RoHS compliance status and lead-free characteristics directly from the official documentation. Ensure the ordering part number matches the required pin configuration and thermal specifications for the target application environment.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a design requires two independent serial ports with high-capacity buffering to minimize processor overhead. The internal oscillator simplifies board layout by removing external crystal requirements. Verify that the operating voltage range aligns with the system power rails. Consider the physical dimensions of the 44-pin PQCC package during PCB footprint design to ensure adequate clearance and solderability.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This component belongs to the XR16C2850 family of dual UART controllers. It shares functional similarities with other members like the XR16C2850CM-F but differs in package type and reel configuration.
