XR16M554DIV64-F Equivalent & Substitute Parts

Part Overview

The XR16M554DIV64-F is a quad-channel UART interface IC with 16-byte FIFO, manufactured by MaxLinear, Inc. This component integrates four independent serial communication channels with RS232 protocol support, internal oscillator, and timer/counter functionality in a 64-LQFP surface mount package. The product is currently obsolete, necessitating identification of equivalent substitute components for ongoing system support and new designs requiring similar functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitute components for the XR16M554DIV64-F are selected based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Number of channels: 4 (QUART configuration)
• Package type: 64-LQFP (10x10) surface mount
• Mounting type: Surface Mount
• Core features: Auto flow control, false start bit detection, modem control

Secondary Compatibility Factors:

• FIFO depth (16 Byte minimum acceptable)
• Data rate capability (minimum 1 Mbps)
• Voltage supply compatibility
• Protocol support (RS232 or equivalent serial interface)

Two substitute parts meet these criteria with varying feature enhancements and compliance profiles.

Parameter Comparison

Engineering Selection Recommendations

SC16C654BIB64,151 (NXP USA Inc.): This substitute offers enhanced performance with 64-byte FIFO depth and 5 Mbps maximum data rate, exceeding the original specification. The component is ROHS3 compliant with superior moisture sensitivity rating (MSL 1). Voltage supply compatibility spans 2.5V, 3.3V, and 5V, providing broader system integration flexibility. The addition of IrDA encoder/decoder functionality extends application scope. Product status is Last Time Buy, indicating controlled availability for transition planning.

TL16CP554APM (Texas Instruments): This substitute maintains functional parity with the original XR16M554DIV64-F, featuring identical 16-byte FIFO and quad-channel configuration. Data rate is limited to 1 Mbps, which may constrain high-speed serial applications. Voltage supply range extends to 5.25V, supporting legacy 5V systems. ROHS3 compliance is confirmed. Product status is Obsolete, similar to the original component, requiring immediate procurement if selected for new designs.

Frequently Asked Questions (FAQ)

Q: Can SC16C654BIB64,151 directly replace XR16M554DIV64-F in existing designs?

A: Yes, from a functional and package perspective. The 64-LQFP (10x10) surface mount package is identical. All four channels, auto flow control, false start bit detection, and modem control features are preserved. The larger 64-byte FIFO and higher 5 Mbps data rate are backward compatible. Verify voltage supply requirements: SC16C654BIB64,151 operates at 2.5V, 3.3V, or 5V, while XR16M554DIV64-F operates at 1.62V ~ 3.63V. Confirm your system voltage falls within both ranges.

Q: What are the key differences between the two substitute options?

A: SC16C654BIB64,151 provides enhanced specifications (64-byte FIFO, 5 Mbps, IrDA support, MSL 1) and is in Last Time Buy status. TL16CP554APM matches the original specifications more closely (16-byte FIFO, 1 Mbps) but is Obsolete. Choose SC16C654BIB64,151 for new designs requiring higher performance and better compliance. Choose TL16CP554APM only if your application requires exact performance matching and legacy system compatibility.

Q: Are there package compatibility concerns?

A: No. Both substitutes use the same 64-LQFP (10x10) surface mount package as the original XR16M554DIV64-F. PCB footprints and reflow soldering profiles are identical.

Q: How do moisture sensitivity levels affect component handling?

A: XR16M554DIV64-F and TL16CP554APM both have MSL 3 (168-hour floor life after moisture exposure). SC16C654BIB64,151 has MSL 1 (unlimited floor life), requiring less stringent moisture control during storage and assembly. For high-volume production or extended storage, SC16C654BIB64,151 offers handling advantages.

Q: Which substitute is recommended for new product development?

A: SC16C654BIB64,151 is the preferred choice for new designs. It offers superior performance specifications, ROHS3 compliance, better moisture sensitivity rating, and Last Time Buy status providing a defined procurement window. TL16CP554APM should be reserved for legacy system maintenance where exact performance matching is required.
