XR17D154IVTR-F

Overview

The XR17D154IVTR-F is a four-channel Universal PCI Bus UART interface integrated circuit manufactured by MaxLinear. It operates within a supply voltage range of 3 V to 5.5 V, supporting both 3.3 V and 5 V logic levels. The device features a data rate capability of 6.25 Mb/s and includes a 64-byte storage capacity per channel. Designed for surface-mount installation in an LQFP-144 package, it supports industrial temperature ranges from -40°C to +85°C. The typical operating power supply current is 4 mA, making it suitable for applications requiring multiple serial ports with PCI bus signaling compatibility.

Feature Summary

• Supports universal PCI bus signaling designs for legacy system integration
• Provides four independent UART channels with dedicated FIFO buffers
• Compatible with standard 3.3 V and 5 V power supply voltages

Applications

• Industrial control systems requiring multiple serial communication ports
• Legacy PCI-based computer expansion cards
• Embedded systems needing high-speed UART connectivity

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to end-of-life status. Check for RoHS compliance documentation and moisture sensitivity level handling requirements during storage and assembly. Confirm package integrity upon receipt to ensure pin alignment matches the LQFP-144 specification before PCB mounting.

Selection Notes

Select this component when designing systems that require four UART interfaces with PCI bus compatibility. Ensure the design accommodates the LQFP-144 footprint and thermal dissipation needs for the specified operating temperature range. Consider the 64-byte FIFO depth for buffer management strategies in high-throughput serial applications.

Part Context

This part belongs to the XR17D154 series of PCI UARTs from MaxLinear. It is distinct from other variants like the XR17D154CV which may have different temperature ratings or packaging options. The IV suffix typically indicates the extended industrial temperature range and tape-and-reel packaging format compared to tray-packed versions.

Replacement Considerations

Public confirmed substitute: XR17V354IB176-F. This alternative offers PCIe interface support with 256-byte FIFOs instead of PCI bus signaling.
