XR16C854IVTR-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The XR16C854IVTR-F is a quad enhanced Universal Asynchronous Receiver/Transmitter (UART) interface integrated circuit manufactured by MaxLinear. It features four independent UART channels, each equipped with 128-byte transmit and receive FIFOs to support high-speed data throughput up to 2 Mb/s. The device operates within a supply voltage range of 2.97 V to 5.5 V and supports both 3.3 V and 5 V logic levels. It is housed in a 64-pin LQFP surface-mount package and is rated for an industrial operating temperature range from -40°C to +85°C.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Quad channel architecture with dedicated 128-byte TX and RX FIFOs per channel
• Support for Intel and Motorola bus compatibility modes
• Integrated internal oscillator and timer/counter functionality
• Automatic hardware flow control and modem control signal management

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial automation systems requiring multiple serial communication ports
• Telecommunications equipment utilizing RS-232 or RS-485 interfaces
• Embedded computing platforms needing high-throughput asynchronous data transfer
• Test and measurement instruments with multi-channel serial logging capabilities

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix IVTR against official MaxLinear documentation to confirm the tape-and-reel packaging and industrial temperature grade. Ensure the ordering part number matches the exact pinout and electrical specifications required for the target design, as suffix variations may indicate different packages or performance grades.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a design requires four independent UART interfaces with deep buffering to prevent data loss during high-baud-rate operations. The 128-byte FIFOs are critical for applications involving bursty data traffic or processor latency issues. Confirm that the system power supply remains stable within the 2.97 V to 5.5 V range to ensure reliable operation across the specified temperature extremes.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the XR16C854D series of quad enhanced UARTs from MaxLinear. It shares core functional characteristics with other variants in the family, such as the XR16C854DIV-F, differing primarily in packaging format and thermal rating. The series is designed to replace legacy UART controllers while offering improved FIFO depths and bus compatibility.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The XR16C854DIV-F is a publicly confirmed substitute offering identical quad-channel functionality and 128-byte FIFOs. Both parts share the same LQFP-64 package and electrical parameters, allowing for potential direct pin-compatible replacement if the packaging style aligns with the manufacturing process.
