XR16C854IV-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The XR16C854IV-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 with dimensions of 10x10 mm. The component supports Intel and Motorola bus interfaces and includes an internal oscillator, timer/counters, automatic flow control, modem control, IrDA encoding/decoding, and false start bit detection capabilities.

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific ordering suffix and package variant against the latest manufacturer datasheet before procurement. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Check current lifecycle status as components may be subject to discontinuation notices. Ensure that the selected quantity matches the minimum order packaging specifications provided by authorized distributors.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when designing systems requiring four independent UART channels with substantial FIFO depth to prevent data loss during burst transmissions. Consider the 64-LQFP package constraints for PCB layout and thermal management. Verify that the operating temperature range meets environmental conditions. Compare power consumption figures against alternative low-power UART solutions if energy efficiency is a primary design constraint.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the XR16C854D series of VLIO UARTs from MaxLinear. It is functionally similar to other variants in the family but distinguished by its specific package type and commercial temperature rating. The series is designed to replace legacy UART controllers while offering enhanced performance through larger FIFOs and higher baud rate capabilities.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Check for direct pin-to-pin replacements within the XR16C854 series such as the XR16C854DIV-F for different package options. Evaluate newer generation UART ICs from MaxLinear or competitors if the XR16C854IV-F is marked as Not Recommended for New Designs (NRND). Ensure functional equivalence regarding FIFO size and supported bus protocols when substituting.
