XR16C854CV-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The XR16C854CV-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-lead LQFP surface-mount package and is rated for commercial operating temperatures from 0°C to +70°C. The component supports 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
• Supports dual bus compatibility including Intel and Motorola interface protocols
• Integrated internal oscillator and timer/counter functionality
• Includes automatic flow control and modem control signal management

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial automation systems requiring multi-port serial communication
• Telecommunications equipment utilizing RS-232 or RS-485 standards
• Embedded computing platforms needing high-throughput serial I/O expansion
• Point-of-sale terminals and payment processing hardware

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix 'CV' confirms the commercial temperature grade (0°C to +70°C) and LQFP-64 package variant. Ensure the ordering part number matches the exact pinout and electrical specifications required by the design. Confirm RoHS compliance status through the manufacturer's official documentation before finalizing procurement orders.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when four independent UART ports with deep buffering are required. Compare against the DIV variant if an extended industrial temperature range (-40°C to +85°C) is necessary. Verify that the 2 Mb/s maximum data rate meets system requirements. Ensure the PCB layout accommodates the 10x10 mm LQFP-64 footprint.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the XR16C854 series of VLIO UARTs from MaxLinear. It serves as a high-performance serial interface solution replacing legacy single-channel UARTs. The series is designed for applications demanding reliable asynchronous serial communication with reduced CPU overhead due to large FIFO buffers.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The XR16C854DIV-F offers identical functional specifications but provides an extended industrial temperature range (-40°C to +85°C). Designers requiring wider thermal operation should consider this alternative while maintaining the same pinout and software compatibility.
