NXP Semiconductors BRKFXPS7XXX-PCB

Overview

BRKFXPS7XXX-PCB from NXP Semiconductors is a blank, unpopulated printed-circuit board designed to host FXPS7250-series barometric absolute pressure (BAP) sensors-supporting analog, I²C, or SPI output variants-with user-selectable passive components and pressure range configurations. It enables rapid prototyping of automotive and industrial pressure sensing applications including manifold absolute pressure (MAP), barometric pressure (BAP), and gas tank monitoring for CNG/LPG systems.

For engineers reviewing the BRKFXPS7XXX-PCB datasheet, BRKFXPS7XXX-PCB pinout, BRKFXPS7XXX-PCB application, or BRKFXPS7XXX-PCB equivalent, this board serves as a flexible hardware foundation for evaluating FXPS7250 sensor variants across multiple interfaces and pressure ranges-requiring no pre-soldered ICs, full BOM customization, and compatibility with FRDM7X-INTERFACE and NXP Freedom MCU platforms.

Technical Context

The BRKFXPS7XXX-PCB is a purpose-built carrier PCB without active components, intended exclusively for populating with FXPS7250A4ST1 (analog), FXPS7250DI4ST1 (I²C), or FXPS7250DS4ST1 (SPI) pressure sensors and associated passives. It provides standardized Arduino-compatible headers and routing optimized for signal integrity, power delivery, and ESD protection per NXP's evaluation design guidelines.

It functions only in conjunction with the FRDM7X-INTERFACE board, which adapts pin mapping and logic levels for seamless interface with FRDM-KE15Z (analog/I²C) or FRDM-K64F (SPI) MCUs. No onboard firmware, voltage regulation, or communication protocol logic resides on BRKFXPS7XXX-PCB itself.

FAQ

What is the primary function of the BRKFXPS7XXX-PCB?

The BRKFXPS7XXX-PCB is an unpopulated evaluation PCB intended solely for user assembly with FXPS7250-series pressure sensors and supporting passives. It provides mechanical and electrical infrastructure-including Arduino-compatible headers and optimized routing-but contains no active components, firmware, or power regulation. Its role is to serve as a customizable hardware platform for sensor evaluation, not a standalone functional device.

Does the BRKFXPS7XXX-PCB include a pre-mounted pressure sensor?

No, the BRKFXPS7XXX-PCB ships completely blank-without any ICs, capacitors, resistors, or connectors populated. Users must manually solder the selected FXPS7250 variant (e.g., FXPS7250A4ST1, FXPS7250DI4ST1, or FXPS7250DS4ST1) and required passives per their target pressure range and interface. This enables full BOM control and variant flexibility not possible with pre-assembled boards.

Which NXP development boards does the BRKFXPS7XXX-PCB work with?

The BRKFXPS7XXX-PCB requires the FRDM7X-INTERFACE board to interface with NXP Freedom MCU platforms. It is validated for use with FRDM-KE15Z (for analog and I²C variants) and FRDM-K64F (for SPI variants). Direct connection to host MCUs is not supported-the FRDM7X-INTERFACE board handles level translation, pin mapping, and protocol adaptation.

Can the BRKFXPS7XXX-PCB be used without the FRDM7X-INTERFACE board?

No-per UM11863 Section 4.1 and Figure 5, the BRKFXPS7XXX-PCB lacks native Arduino header pinout alignment and logic-level compatibility. The FRDM7X-INTERFACE board is mandatory to provide correct signal routing, voltage translation (e.g., 3.3 V ↔ 5 V), and switch-selectable protocol configuration (analog/I²C/SPI). Using BRKFXPS7XXX-PCB alone yields no functional interface.

Is the BRKFXPS7XXX-PCB qualified for automotive production use?

No-the BRKFXPS7XXX-PCB is explicitly designated for engineering development or evaluation purposes only, as stated in UM11863 Section "IMPORTANT NOTICE". It is not a reference design, lacks production-grade layout controls (e.g., thermal management, EMI shielding, safety isolation), and requires full revalidation for any end-product implementation. NXP disclaims liability for use outside evaluation contexts.
