XR16C854DIVTR-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The XR16C854DIVTR-F is a quad enhanced Universal Asynchronous Receiver/Transmitter (UART) interface integrated circuit manufactured by MaxLinear. It features four independent channels, each equipped with 128-byte transmit and receive FIFOs to improve data throughput and reduce CPU overhead. The device supports data rates up to 2 Mb/s and operates within a supply voltage range of 2.97 V to 5.5 V. It is housed in a 64-pin LQFP surface-mount package and is designed for industrial temperature ranges from -40°C to +85°C. The component supports both Intel and Motorola bus interfaces.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Quad channel architecture with dedicated 128-byte TX and RX FIFOs per channel
• Support for high-speed asynchronous serial communication up to 2 Mb/s
• Dual bus compatibility supporting both Intel and Motorola interface protocols
• Integrated modem control signals and automatic flow control capabilities

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial automation systems requiring multiple serial connections
• Telecommunications equipment utilizing RS-232 or RS-485 interfaces
• Embedded computing platforms needing high-throughput UART expansion
• Test and measurement instruments with multi-channel serial monitoring

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when sourcing this component. Confirm that the operating temperature grade matches the required environmental conditions for your application. Ensure compatibility with the target system's voltage levels and bus protocol requirements before integration.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this model when multiple independent UART channels are required on a single PCB. The 128-byte FIFO depth makes it suitable for applications with bursty data traffic or varying processor speeds. Compare against the XR16C854DIV variant if tray packaging is preferred over reel packaging for assembly processes.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This component belongs to the XR16C854D series of enhanced UARTs from MaxLinear. It shares functional similarities with other members like the XR16C854DIV but differs in packaging format. The series is designed to replace legacy UART controllers in modern embedded designs requiring higher performance and flexibility.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The XR16C854DIV serves as a direct pin-compatible alternative with identical electrical characteristics, differing only in shipping packaging. Verify that any substitute maintains the same 64-LQFP footprint and 128-byte FIFO configuration.
