NXP Semiconductors BRKTSTBAPDI7250

Overview

BRKTSTBAPDI7250 from NXP Semiconductors is an I2C-interface evaluation breakout board for the FXPS7250DI4ST1 digital barometric absolute pressure (BAP) sensor, designed to interface directly with NXP Freedom MCU development platforms via the FRDM7X-INTERFACE adapter. It delivers calibrated digital pressure and temperature data over I2C, supports 15–400 kPa absolute pressure range, operates from 3.0–5.5 V supply, and targets automotive intake manifold and gas tank pressure monitoring.

For engineers reviewing the BRKTSTBAPDI7250 datasheet, BRKTSTBAPDI7250 pinout, BRKTSTBAPDI7250 application, or BRKTSTBAPDI7250 equivalent, this page provides verified hardware configuration guidance, I2C signal mapping, software integration notes with MCUXpresso SDK, and compatibility details with FRDM-KE15Z for rapid sensor evaluation in automotive and industrial pressure-sensing systems.

Technical Context

The BRKTSTBAPDI7250 implements a fixed-function hardware interface between the FXPS7250DI4ST1 MEMS pressure sensor and host microcontrollers, using standard Arduino-compatible headers and requiring the FRDM7X-INTERFACE board for signal level translation and protocol adaptation. Its I2C interface operates at standard (100 kHz) and fast (400 kHz) modes with pull-up resistors pre-installed on SDA/SCL lines.

This board contains no active logic or firmware; it routes VCC, GND, SDA, SCL, INT, and VCCIO signals from the FXPS7250DI4ST1 to edge connectors, enabling direct connection to NXP Freedom boards. It does not include onboard voltage regulation or ESD protection beyond basic layout-level decoupling capacitors (C1).

FAQ

What is the primary function of the BRKTSTBAPDI7250 evaluation board?

The BRKTSTBAPDI7250 is a dedicated I2C-interface breakout board for the FXPS7250DI4ST1 digital barometric absolute pressure sensor. It provides direct access to sensor signals-including SDA, SCL, INT, VCC, and GND-via Arduino-compatible headers. The BRKTSTBAPDI7250 requires the FRDM7X-INTERFACE board to connect to NXP Freedom MCUs like the FRDM-KE15Z, enabling rapid firmware validation and pressure data acquisition without custom PCB design.

Which NXP MCU boards are officially supported with the BRKTSTBAPDI7250?

The BRKTSTBAPDI7250 is officially supported with the FRDM-KE15Z MCU board when used together with the FRDM7X-INTERFACE adapter. This combination enables I2C communication at up to 400 kHz and is validated with NXP's Component Library sensor drivers and MCUXpresso SDK examples. The BRKTSTBAPDI7250 is not directly compatible with FRDM-K64F, which is designated for SPI-based variants like BRKTSTBAPDS7250.

Does the BRKTSTBAPDI7250 include onboard firmware or processing capability?

No, the BRKTSTBAPDI7250 contains no microcontroller, flash memory, or executable firmware. It is a passive hardware interface board that routes signals from the FXPS7250DI4ST1 sensor to external hosts. All sensor initialization, register configuration, and data parsing must be performed by the connected MCU-such as the FRDM-KE15Z-using NXP's provided sensor driver libraries. The BRKTSTBAPDI7250 itself performs no signal processing or calibration.

How is I2C communication configured on the BRKTSTBAPDI7250?

The BRKTSTBAPDI7250 features onboard 4.7 kΩ pull-up resistors on both SDA and SCL lines, compliant with standard I2C bus requirements. It uses the default I2C address 0x28 for the FXPS7250DI4ST1 sensor. Communication is initiated by the host MCU (e.g., FRDM-KE15Z), with the INT pin providing optional interrupt-driven status signaling. No DIP switches or jumpers are required for basic I2C operation-the BRKTSTBAPDI7250 is pre-configured for I2C use out-of-box.

Can the BRKTSTBAPDI7250 be used without the FRDM7X-INTERFACE board?

No-the BRKTSTBAPDI7250 lacks native Arduino pinout alignment and level-shifting circuitry required for direct connection to Freedom MCU boards. It must be used with the FRDM7X-INTERFACE board, which adapts its signal routing, provides VCCIO selection (3.3 V/5 V), and enables protocol switching (I2C/analog/SPI) via SW1. Attempting direct connection risks signal incompatibility, incorrect voltage levels, or communication failure. The BRKTSTBAPDI7250 is not a standalone evaluation solution.
