NXP Semiconductors BRKTSTBAPA7250S

Overview

BRKTSTBAPA7250S from NXP Semiconductors is an analog-output evaluation breakout board for the FXPS7250A4ST1 barometric absolute pressure (BAP) sensor, designed to interface directly with host MCU ADC inputs. It supports 15–400 kPa pressure range, delivers ratiometric analog voltage output (0.1–4.9 V), operates from 3.3 V supply, and targets automotive intake manifold and gas tank pressure monitoring.

For engineers reviewing the BRKTSTBAPA7250S datasheet, BRKTSTBAPA7250S pinout, BRKTSTBAPA7250S application, or BRKTSTBAPA7250S equivalent, this board enables rapid functional validation of analog BAP sensing in engine control units, CNG/LPG fuel systems, and environmental pressure logging-without custom PCB design or signal conditioning.

Technical Context

The BRKTSTBAPA7250S implements a pre-soldered FXPS7250A4ST1 MEMS capacitive pressure sensor with integrated signal conditioning, delivering factory-calibrated analog output referenced to VCC. It requires no external configuration registers or digital communication protocol handling.

It interfaces via standard Arduino-compatible headers and relies on the FRDM7X-INTERFACE board to route analog signals (VOUT, VREF+, VREF−, GND, VCC) to compatible NXP Freedom MCUs such as FRDM-KE15Z. No firmware modification is needed to acquire raw pressure data through the onboard ADC path.

FAQ

What is the BRKTSTBAPA7250S used for?

The BRKTSTBAPA7250S is an analog-output evaluation breakout board for the FXPS7250A4ST1 pressure sensor, enabling rapid functional testing of barometric and manifold absolute pressure measurement in automotive and industrial applications. It provides direct access to calibrated analog voltage output without requiring digital protocol implementation, making it ideal for validating sensor behavior in engine control units and gas-fueled vehicle systems.

Does the BRKTSTBAPA7250S require additional hardware to operate?

Yes - the BRKTSTBAPA7250S requires the FRDM7X-INTERFACE board to adapt its signals to Arduino headers and an NXP Freedom MCU board (e.g., FRDM-KE15Z) for power, ADC acquisition, and serial output. The BRKTSTBAPA7250S itself contains only the pre-soldered FXPS7250A4ST1 sensor and passive components; it does not include microcontroller or USB interface functionality.

What pressure range does the BRKTSTBAPA7250S support?

The BRKTSTBAPA7250S supports a 15–400 kPa absolute pressure range, matching the specifications of the onboard FXPS7250A4ST1 sensor. This range accommodates barometric pressure monitoring (≈80–110 kPa), intake manifold pressure in gasoline engines (≈20–100 kPa), and CNG/LPG tank pressure (up to 400 kPa), all within a single calibrated device.

Can the BRKTSTBAPA7250S be used standalone without the FRDM7X-INTERFACE board?

No - the BRKTSTBAPA7250S lacks Arduino-compatible pin spacing and signal routing logic. Its JP1 and JP2 6-pin headers are not aligned to standard Arduino pinouts; the FRDM7X-INTERFACE board is mandatory to translate and route analog signals (VOUT, VREF+, VREF−, VCC, GND) correctly to the MCU's ADC input channels and reference pins.

Is the BRKTSTBAPA7250S suitable for production use?

No - the BRKTSTBAPA7250S is explicitly designated for engineering development or evaluation purposes only, as stated in NXP's UM11863 user manual. It is not a reference design, lacks final EMC/thermal optimization, and omits safety-critical protections required for end-product deployment. Production designs must integrate the FXPS7250A4ST1 sensor directly onto a validated PCB.
