XR17D154CV Equivalent & Substitute Parts

Part Overview

The XR17D154CV is a quad-channel UART interface IC designed for PCI bus applications with RS485 protocol support. This component integrates four independent UART channels with 64-byte FIFOs, IrDA encoder/decoder functionality, and false start bit detection capabilities. The device operates at supply voltages of 3.3V and 5V, supporting data rates up to 6.25 Mbps.

The XR17D154CV is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain system compatibility, ensure continued availability for legacy system support, and facilitate design updates when original inventory becomes depleted.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the XR17D154CV is determined by strict equivalence across the following critical parameters:

• Channel Configuration: 4 independent UART channels (QUART architecture)
• FIFO Capacity: 64-byte buffer per channel
• Communication Protocol: RS485 serial interface
• Maximum Data Rate: 6.25 Mbps operation
• Supply Voltage Compatibility: Dual-voltage operation (3.3V and 5V)
• Functional Features: IrDA encoder/decoder and false start bit detection
• Package Specification: 144-LQFP (20x20) surface mount form factor
• Thermal and Environmental Rating: MSL 3 (168 Hours)

The XR17D154IV-F qualifies as a parametric equivalent substitute, maintaining identical electrical specifications and functional capabilities while differing only in packaging format (Tray versus standard packaging) and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the XR17D154CV and XR17D154IV-F are classified as obsolete products from MaxLinear, Inc. The XR17D154IV-F offers the advantage of RoHS compliance certification, making it suitable for applications subject to environmental and regulatory restrictions. The packaging difference (Tray format for the IV-F variant) may influence procurement logistics and handling procedures but does not affect electrical or functional performance.

Selection between these parts should be based on regulatory requirements, inventory availability, and packaging compatibility with existing assembly processes. Both parts maintain identical electrical specifications and functional capabilities for RS485 UART interface applications.

Frequently Asked Questions (FAQ)

Q: Can the XR17D154IV-F directly replace the XR17D154CV in existing designs?

A: Yes. The XR17D154IV-F is a parametric equivalent with identical electrical specifications, channel configuration, FIFO depth, data rate capability, supply voltage range, and functional features. Both parts use the same 144-LQFP (20x20) package and mounting type. The primary differences are packaging format and RoHS compliance status, which do not affect electrical compatibility.

Q: What is the significance of the packaging format difference between these parts?

A: The XR17D154CV uses standard packaging, while the XR17D154IV-F is supplied in Tray format. This difference affects handling, storage, and assembly line integration but does not impact electrical performance or pin configuration. Verify compatibility with your procurement and assembly processes.

Q: Why is RoHS compliance status different between these parts?

A: The XR17D154IV-F carries RoHS Compliant certification, while the XR17D154CV does not specify this status. RoHS compliance is required for applications subject to environmental regulations in specific markets and industries. Select the RoHS-compliant variant if your application or market requires this certification.

Q: Are there any differences in thermal or environmental ratings?

A: No. Both parts share identical Moisture Sensitivity Level (MSL) ratings of 3 (168 Hours), ensuring equivalent handling and storage requirements.

Q: What should be considered when sourcing these obsolete parts?

A: Both parts are classified as obsolete. Verify current inventory availability with authorized distributors. Consider long-term supply chain implications and evaluate whether design migration to current-generation interface ICs is feasible for future production runs.
