XR16C854DCV-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The XR16C854DCV-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, supporting 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 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 Intel and Motorola bus compatibility modes
• Integrated dual footprints for flexible pinout configuration

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial automation systems requiring multiple serial communication ports
• Embedded control units utilizing Intel or Motorola bus interfaces
• Data acquisition modules needing high-capacity FIFO buffering

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix 'DCV' against the official MaxLinear datasheet to confirm the commercial temperature grade (0°C to +70°C) and LQFP-64 packaging. Ensure that the procurement source provides valid RoHS compliance documentation. Cross-reference the manufacturer part number directly with MaxLinear's current product status to avoid obsolete stock.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when four independent UART channels with large FIFO buffers are required in a compact surface-mount form factor. The DCV variant is suitable for commercial applications where the extended -40°C to +85°C range of the DIV variant is not necessary. Verify that the system power supply remains within the 2.97 V to 5.5 V operational limits.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the XR16C854D series of quad enhanced UARTs. It shares core functionality with the XR16C854DIV-F but differs in temperature rating and packaging. The series is designed for applications requiring robust serial communication with reduced CPU overhead due to deep FIFOs.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The XR16C854DIV-F serves as a direct functional substitute with identical electrical characteristics, differing only in the extended industrial temperature range (-40°C to +85°C). No other cross-model substitutes are confirmed in the provided documentation.
