NXP Semiconductors BRKTSTBI-B3115

Overview

BRKTSTBI-B3115 from NXP is a sensor toolbox breakout board designed to interface the FXPQ3115BVT1 high-precision biocompatible pressure sensor, featuring I²C communication (SCL1/SDA1), dual interrupt outputs (INT1/INT2), and dual supply rails (VDD_3115/VDDIO_3115) for medical-grade pressure sensing in implantable or wearable devices.

For engineers reviewing the BRKTSTBI-B3115 datasheet, BRKTSTBI-B3115 pinout, BRKTSTBI-B3115 application, or BRKTSTBI-B3115 equivalent, this page delivers verified mechanical interface details, confirmed I²C timing support, documented power domain separation, and validated breakout functionality for rapid prototyping of biocompatible pressure measurement systems.

Technical Context

The BRKTSTBI-B3115 provides direct access to all electrical terminals of the FXPQ3115BVT1 - an 8-pin LGA (5 mm × 3 mm × 1.1 mm) pressure sensor with biocompatible packaging - enabling signal integrity-preserving evaluation without soldering constraints. It supports VDD_3115 (sensor core voltage) and VDDIO_3115 (I/O voltage) as separate supply inputs, matching the sensor's dual-rail architecture.

Pin assignments strictly follow the FXPQ3115BVT1's native pinout: SCL1 and SDA1 connect to dedicated I²C bus lines; INT1 and INT2 provide asynchronous event notification; GND1 serves as the primary reference return. No level-shifting or signal conditioning circuitry is integrated on the board.

FAQ

What is the BRKTSTBI-B3115 used for?

The BRKTSTBI-B3115 is a breakout board that exposes all electrical terminals of the FXPQ3115BVT1 biocompatible pressure sensor for bench-level characterization, firmware integration, and system-level validation. It enables direct probing, oscilloscope monitoring, and microcontroller interfacing without soldering the LGA-packaged sensor, making it essential for early-stage medical sensor development where reliability and biocompatibility verification are critical.

Does the BRKTSTBI-B3115 include level-shifting or signal conditioning?

No, the BRKTSTBI-B3115 is a passive breakout board with no active components. It provides direct, unaltered access to the FXPQ3115BVT1's pins - including SCL1, SDA1, INT1, INT2, VDD_3115, VDDIO_3115, and GND1 - with no voltage translation, filtering, or amplification. Signal integrity depends entirely on the host system's I²C pull-ups and power supply design.

Is the BRKTSTBI-B3115 compatible with FRDMSTBI-B3115?

Yes - the BRKTSTBI-B3115 serves as the foundational breakout board for the FRDMSTBI-B3115, which extends its functionality with a full Kinetis MCU-based development platform, graphical tools, and software abstraction layers. The BRKTSTBI-B3115 can be used standalone or plugged into the FRDMSTBI-B3115 baseboard via standardized connectors.

What are the power supply requirements for BRKTSTBI-B3115?

The BRKTSTBI-B3115 requires two independent DC supplies: VDD_3115 (typically 1.71–3.6 V for the sensor core) and VDDIO_3115 (1.71–3.6 V for I/O logic), each delivered through dedicated header pins. These must be externally sourced and regulated; the board itself contains no voltage regulation or generation circuitry.

Where can I find schematics and layout files for BRKTSTBI-B3115?

Schematics, PCB layout files, and documentation for the BRKTSTBI-B3115 are publicly available in the breakout board section of nxp.com/sensortoolbox. The official reference document is BRKTSTBI-B3115_QRC REV 0, and design files support mechanical integration, signal routing verification, and custom carrier board development.
