XR17D158CVTR-F

Overview

The XR17D158CVTR-F is an octal Universal PCI Bus UART integrated circuit manufactured by MaxLinear. It provides eight independent asynchronous serial communication channels within a single package, designed for high-density interface applications. The device supports data rates up to 6.25 Mbps and includes a 64-byte FIFO buffer per channel to manage data throughput efficiently. It operates on a single 5V power supply with a specified range of 4.5V to 5.5V. The component is housed in a 144-lead Thin Quad Flat Package (TQFP) with a 20x20 mm footprint, suitable for surface-mount assembly. This part number specifically denotes the tape-and-reel packaging variant intended for automated manufacturing processes.

Feature Summary

• Integrates eight fully independent UART channels to maximize board space efficiency
• Supports RS485 signaling protocols for robust industrial communication
• Includes built-in IrDA encoder and decoder functionality for infrared connectivity
• Features automatic hardware flow control to prevent data loss during transmission

Applications

• Industrial automation systems requiring multiple serial connections
• Telecommunications infrastructure equipment
• Point-of-sale (POS) terminals and payment systems
• Medical instrumentation devices

Procurement Notes

Verify the specific suffix 'TR' confirms the tape-and-reel packaging format required for your assembly line. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the 144-LQFP/TQFP pinout matches your PCB layout design exactly. Check for any recent product change notices regarding material composition or assembly site changes.

Selection Notes

Select this component when designing systems that require eight distinct serial ports without expanding the bill of materials with multiple discrete controllers. Consider the 64-byte FIFO depth relative to your processor's interrupt handling capabilities. Evaluate the 144-pin package density against your available board real estate and thermal dissipation requirements compared to lower-channel alternatives.

Part Context

This component belongs to the XR17C158/XR17D158 family of universal PCI bus UARTs from MaxLinear. These devices are engineered to replace legacy multi-port UART solutions in modern embedded designs. The XR17D158 series offers enhanced performance over previous generations while maintaining compatibility with standard PCI bus signaling designs used in various industrial and commercial applications.

Replacement Considerations

The XR17V358IB176-F is listed as a manufacturer-recommended alternative. Verify functional equivalence and pin compatibility before substitution. Note that newer revisions may offer updated features or packaging options.
