XR16V554DIV-F Equivalent & Substitute Parts

Part Overview

The XR16V554DIV-F is a quad-channel UART interface IC with 16-byte FIFO, manufactured by MaxLinear, Inc. This surface-mount component operates across a 2.25V to 3.6V supply range and supports RS232 protocol with a maximum data rate of 4Mbps. The device includes internal oscillator, timer/counter functionality, auto flow control, false start bit detection, and modem control capabilities.

The XR16V554DIV-F maintains Active product status with 3965 units currently in stock. Substitute parts are necessary when addressing supply constraints, end-of-life transitions, or specific application requirements that may benefit from alternative electrical or mechanical characteristics within the same functional category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the XR16V554DIV-F is determined by the following critical parameters:

• Package Compatibility: All substitutes must use 64-LQFP (10x10) surface-mount packaging to ensure PCB layout compatibility
• Channel Configuration: Quad-channel (4 QUART) architecture is mandatory for functional equivalence
• Core Protocol Support: RS232 protocol support or protocol-agnostic architecture
• Control Features: Auto flow control, false start bit detection, and modem control capabilities
• Electrical Compatibility: Supply voltage range and data rate specifications must support the application requirements
• Mechanical Compatibility: Surface-mount technology and identical package dimensions

The two identified substitute parts meet these criteria with variations in FIFO depth, maximum data rate, supply voltage range, and product lifecycle status.

Parameter Comparison

Engineering Selection Recommendations

SC16C654BIB64,151 (NXP USA Inc.)

This substitute offers enhanced FIFO capacity (64 Byte versus 16 Byte) and superior maximum data rate (5Mbps versus 4Mbps). The part supports multiple supply voltage options (2.5V, 3.3V, 5V) and carries ROHS3 compliance with MSL 1 rating, indicating superior moisture tolerance. However, the part carries Last Time Buy status, indicating limited future availability. Selection is appropriate for applications requiring higher throughput or extended moisture exposure tolerance, provided long-term supply is not critical.

TL16CP554APM (Texas Instruments)

This substitute maintains identical FIFO depth (16 Byte) to the primary part but operates at reduced maximum data rate (1Mbps versus 4Mbps) and requires higher supply voltage range (3V ~ 5.25V). The part carries Obsolete product status, indicating no further manufacturing or support. Selection is not recommended for new designs due to lifecycle status and reduced performance specifications.

Frequently Asked Questions (FAQ)

Q: Can SC16C654BIB64,151 be used as a direct replacement for XR16V554DIV-F?

A: SC16C654BIB64,151 is functionally compatible within the same 64-LQFP package and maintains quad-channel UART architecture with all required control features. However, the increased FIFO depth (64 Byte) and higher maximum data rate (5Mbps) represent functional enhancements rather than direct equivalence. Verify that your application can accommodate these parameter differences and that supply voltage compatibility exists in your system design.

Q: What is the significance of the FIFO size difference between these parts?

A: FIFO (First-In-First-Out) buffer depth affects data buffering capacity. The XR16V554DIV-F and TL16CP554APM both provide 16-byte FIFO, while SC16C654BIB64,151 provides 64-byte FIFO. Larger FIFO reduces the risk of data loss during high-speed serial communication or when processor interrupt latency is significant. Selection depends on your application's data throughput and interrupt handling characteristics.

Q: Are there supply voltage compatibility concerns?

A: The XR16V554DIV-F operates at 2.25V ~ 3.6V. SC16C654BIB64,151 supports 2.5V, 3.3V, and 5V discrete levels, while TL16CP554APM requires 3V ~ 5.25V. Verify that your system's power supply voltage matches the selected part's specifications. SC16C654BIB64,151 offers broader voltage flexibility for multi-voltage systems.

Q: What does product status mean for component selection?

A: Active status indicates ongoing manufacturing and support. Last Time Buy indicates the manufacturer will cease production after a specified date, with limited remaining inventory. Obsolete status indicates the manufacturer has discontinued production and support. For new designs, Active status parts are preferred. Last Time Buy parts require careful inventory planning. Obsolete parts should be avoided unless existing systems require maintenance.

Q: Is the 64-LQFP package identical across all three parts?

A: Yes. All three parts use 64-LQFP (10x10) surface-mount packaging with identical physical dimensions and pin configurations. PCB layout compatibility is maintained across all substitutes without requiring design modifications.
