XR16C854CQTR-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The XR16C854CQTR-F is a quad universal asynchronous receiver and transmitter (UART) interface integrated circuit manufactured by MaxLinear. It features four independent channels, each equipped with 128-byte transmit and receive FIFOs to enhance 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 QFP-100 surface-mount package and is designed for industrial applications with an operating temperature range of 0°C to +70°C.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Quad channel architecture with dedicated 128-byte TX and RX FIFOs per channel
• Supports both Intel and Motorola bus interfaces for flexible system integration
• Integrated modem control signals and automatic flow control capabilities

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial communication systems requiring multiple serial ports
• Embedded controllers needing high-throughput UART connectivity
• Data acquisition systems utilizing buffered serial transmission

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix 'CQTR' against official MaxLinear documentation to confirm the QFP-100 package and tape-and-reel shipping format. Ensure the commercial temperature grade (0°C to +70°C) aligns with your design requirements. Cross-reference the part number with current lifecycle status, as availability may vary due to manufacturing updates or end-of-life notices.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when multiple UART interfaces are required in a compact form factor. The 128-byte FIFOs are suitable for applications with bursty data traffic. Compare against the XR16C854DIV-F if a lower pin count LQFP-64 package is preferred, noting that pin compatibility may differ. Verify power consumption specifications against system thermal constraints.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the XR16C854 series of enhanced UARTs from MaxLinear. The series is characterized by its dual-bus support and large FIFO buffers. The 'CQ' designation typically indicates the QFP-100 package variant, while 'TR' denotes reel packaging. This family serves as a drop-in replacement for legacy UARTs in multi-port designs.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Check for direct substitutes such as the XR16C854CQ-F (tube packaging) if reel format is not critical. Evaluate the XR16C854DIV-F for potential space savings if the application allows for a different pinout configuration.
