NXP Semiconductors KITPRESSURE1EVB

Overview

KITPRESSURE1EVB from Freescale Semiconductor is an evaluation board designed to demonstrate and develop with the MPL115A1 precision I²C digital barometric pressure sensor. It provides USB plug-and-play connectivity, on-board voltage regulation, and direct sensor interface for gauge and absolute pressure measurement in altimetry, barometry, and medical monitoring applications.

For engineers reviewing the KITPRESSURE1EVB datasheet, KITPRESSURE1EVB pinout, KITPRESSURE1EVB application, or KITPRESSURE1EVB equivalent, this board supports rapid prototyping of pressure-sensing functions including PSI conversion, altitude calculation, and liquid-level monitoring using Freescale's Xtrinsic sensor ecosystem and Sensor Toolbox GUI software.

Technical Context

The KITPRESSURE1EVB implements a dedicated hardware interface between the MPL115A1 pressure transducer and the LFSTBUSB host interface board, enabling real-time I²C communication at standard (100 kHz) and fast (400 kHz) modes. It includes calibrated sensor output scaling, temperature compensation circuitry, and onboard 3.3 V LDO regulation optimized for low-noise analog front-end operation.

Designed as part of Freescale's unified Sensor Toolbox architecture, the KITPRESSURE1EVB relies on shared firmware infrastructure - including pressure-specific algorithms for PSI-to-kPa conversion and altimetry compensation - accessible via the freemaster-based GUI at freescale.com/sensortoolbox.

Manufacturer

Freescale Semiconductor (now part of NXP Semiconductors) is a pioneer in MEMS-based sensing solutions, delivering high-accuracy, low-power sensor ICs for automotive, industrial, and consumer applications since the 1980s.

The KITPRESSURE1EVB belongs to Freescale's Xtrinsic Sensor Toolbox family - engineered to accelerate time-to-market for pressure-aware systems by unifying hardware evaluation, algorithmic processing, and GUI-driven validation across MPL115A1, MPL3115A2, and MPXV5004DP platforms.

FAQ

What is the primary sensor used on the KITPRESSURE1EVB evaluation board?

The KITPRESSURE1EVB evaluation board is built around the MPL115A1 - a precision, I²C-compatible digital barometric pressure sensor with integrated temperature compensation and factory-trimmed calibration coefficients. This sensor delivers 1.5 kPa total error band over 0–85 °C and supports both gauge and absolute pressure measurement modes essential for the KITPRESSURE1EVB's intended use cases.

Does the KITPRESSURE1EVB require additional hardware to operate?

Yes - the KITPRESSURE1EVB requires the LFSTBUSB host interface board or a compatible Freescale Freedom platform (e.g., FRDM-FXS-MULTI-B) to establish USB communication and power delivery. It does not include an on-board microcontroller or USB transceiver; instead, it functions as a daughterboard that connects directly to these host platforms to enable sensor data acquisition and GUI interaction via the KITPRESSURE1EVB.

Which software tools are supported for configuring and reading data from the KITPRESSURE1EVB?

The KITPRESSURE1EVB is fully supported by Freescale's Sensor Toolbox GUI software, available at freescale.com/sensortoolbox. This application provides real-time pressure and temperature visualization, unit conversion (kPa, PSI, inHg, meters), data logging, and access to embedded pressure algorithms - all without requiring custom firmware development for the KITPRESSURE1EVB.

Can the KITPRESSURE1EVB be used for absolute pressure measurements such as altimetry?

Yes - the MPL115A1 sensor on the KITPRESSURE1EVB is an absolute pressure transducer, making it suitable for altimetry applications. Its 50–115 kPa range and built-in temperature compensation allow accurate elevation estimation when referenced to sea-level pressure, and the Sensor Toolbox GUI includes dedicated altimeter mode with configurable reference pressure for the KITPRESSURE1EVB.

Is the KITPRESSURE1EVB compatible with other Freescale sensor evaluation kits?

Yes - the KITPRESSURE1EVB uses the standardized Sensor Toolbox mechanical and electrical interface, allowing interoperability with KITMPL115A1EVB, KITMPXV5004DPEVB, and KITMMA9550LEVM boards when mounted on shared baseboards like LFSTBEB845X. All share identical I²C addressing conventions and GUI command structures within the KITPRESSURE1EVB ecosystem.
