Product details

Overview

MPL3150A2 from NXP Semiconductors is a compact, piezoresistive absolute pressure sensor with integrated I2C digital interface, 20-bit pressure resolution (0.25 Pa typical), −40 °C to +85 °C operating range, and on-chip temperature compensation - enabling high-accuracy barometric sensing in space-constrained portable electronics.

For engineers reviewing the MPL3150A2 datasheet, MPL3150A2 pinout, MPL3150A2 application, or MPL3150A2 equivalent, this device delivers fully compensated pressure (Pascals) and temperature (°C) outputs without MCU-side unit conversion or compensation math - reducing firmware overhead and simplifying system-level timing and power management in battery-powered navigation and environmental monitoring designs.

Technical Context

The MPL3150A2 integrates a MEMS pressure die with an on-chip temperature sensor, high-resolution ADC, digital signal processing ASIC, and 32-sample FIFO - all operating within a single 5 mm × 3 mm × 1.1 mm LGA package. Its architecture supports autonomous acquisition cycles from 1 second to 9 hours and programmable interrupt routing to INT1/INT2 pins.

Internal voltage regulation enables stable operation across 1.95 V–3.6 V VDD and 1.62 V–3.6 V VDDIO supplies. The device implements end-point linearity correction and factory-trimmed offset calibration stored in on-chip NVM, with user-accessible volatile registers for runtime offset adjustment to compensate for mounting stress.

Key Specifications

Parameter	Value and Actual Design Meaning
Pressure Range	50 kPa to 150 kPa absolute - covers sea-level barometric pressure (≈101.3 kPa) with 50 kPa margin for altitude extremes up to ≈5,500 m.
Pressure Accuracy	±0.4 kPa over 70–150 kPa at −10 °C to +70 °C - enables ±3.5 m altitude resolution in GPS dead reckoning applications.
Resolution	0.25 Pa RMS (128× oversample) - supports sub-centimeter altitude change detection in wearable step-counting or indoor navigation.
Output Format	20-bit pressure (Pascals), 12-bit temperature (°C) - direct-read values eliminate MCU floating-point conversion and reduce firmware latency.
I²C Address	0x62 (7-bit) - fixed address simplifies multi-sensor bus design without address conflict risk in compact PCB layouts.

Operating Temp	−40 °C to +85 °C - qualified for automotive cabin, industrial handheld, and outdoor consumer device environments.

Pinout & Package

Package: 8-pin LGA (5.0 mm × 3.0 mm × 1.1 mm), RoHS-compliant, with exposed cavity for pressure port access.

Pin/Terminal	Circuit Role	Design Meaning
VDD	Analog supply input	1.95–3.6 V main power; requires 10 µF + 100 nF decoupling near pin 1 to stabilize internal regulator.
CAP	External compensation capacitor	Connects to internal oscillator tuning node; value affects startup time and noise performance - typically 100 nF ceramic.
GND	Ground reference	Common return for analog/digital domains; must be low-impedance and isolated from noisy digital ground planes.
VDDIO	Digital I/O supply	1.62–3.6 V interface rail; independent of VDD - allows level-shifting with 1.8 V or 3.3 V host MCUs without external translators.
INT2	Programmable interrupt output	Open-drain/push-pull configurable; routes SRC_PTH, SRC_PW, SRC_TTH, FIFO events - offloads polling from host MCU.
INT1	Programmable interrupt output	Independent of INT2; supports simultaneous pressure delta (SRC_PCHG), temperature delta (SRC_TCHG), or data-ready triggers.
SDL	I²C serial data line	Bi-directional, open-drain; requires external pull-up; compatible with standard/fast-mode I²C (up to 400 kHz) and fast-mode plus (4 MHz).
SCL	I²C serial clock line	Input-only; clock synchronizes all register reads/writes and FIFO access - no clock stretching supported.

Key Features

Feature	Design Value
Fully compensated output	On-die temperature sensor + ADC + digital signal processing deliver ready-to-use Pascal and °C values - eliminates MCU-based compensation routines and floating-point libraries.
Autonomous FIFO logging	32-sample buffer stores timestamped pressure/temperature pairs; supports up to 12 days of 1-hour interval logging - enables offline environmental trend analysis without host intervention.
Programmable interrupt engine	Two independent INT pins route 9 distinct event sources (e.g., pressure threshold, delta, FIFO watermark) - reduces host wake-ups and extends sleep duration in ultra-low-power systems.
Multi-mode power optimization	STANDBY (2 µA), ACTIVE (40 µA @ 1 Hz), and OFF modes allow precise trade-off between response latency and energy use - critical for wearable motion-triggered altitude tracking.
User-adjustable offset calibration	Volatile offset registers override factory trims post-mounting - corrects mechanical stress-induced drift (±0.15 kPa board mount drift) without requiring re-calibration equipment.

Equivalent & Alternatives

The following parts are listed as comparable options for similar absolute pressure sensing applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BMP388 (Bosch)	Higher max pressure (1260 kPa), lower typical current (3.6 µA standby), but no FIFO and only 1 interrupt pin.	Lacks autonomous logging capability; requires continuous host polling or external memory for trend analysis.	Select BMP388 when extended pressure range or ultra-low standby current is prioritized over onboard data buffering.
MS5637-02BA03 (TE Connectivity)	Same 50–110 kPa range and I²C interface, but 18-bit pressure resolution (1.5 Pa) and no temperature compensation for pressure output.	Requires host-side temperature compensation math and delivers coarser altitude resolution (±10 m vs. ±3.5 m).	Choose MS5637-02BA03 where cost sensitivity outweighs resolution needs and firmware resources exist for compensation routines.

Compared with BMP388 and MS5637-02BA03, the MPL3150A2 uniquely combines 20-bit pressure resolution, 32-sample FIFO, dual programmable interrupts, and full on-die temperature-compensated output - making it optimal for applications demanding autonomous, high-fidelity barometric logging without host computational overhead.

FAQ

What is the absolute pressure range and accuracy specification of the MPL3150A2?

The MPL3150A2 has an operational pressure range of 50 kPa to 150 kPa and a calibrated range of 70 kPa to 150 kPa. Its absolute pressure accuracy is ±0.4 kPa over 70–150 kPa at −10 °C to +70 °C, verified per NXP's characterization data. This corresponds to ±3.5 m altitude resolution at sea level, making MPL3150A2 suitable for barometric altimetry in consumer and industrial navigation systems.

How does the MPL3150A2 reduce MCU processing load compared to raw sensor outputs?

The MPL3150A2 performs full temperature compensation, unit conversion, and digital signal processing internally - delivering ready-to-use 20-bit pressure values in Pascals and 12-bit temperature values in °C via I²C. Unlike uncompensated sensors, MPL3150A2 eliminates the need for host MCU floating-point math, lookup tables, or calibration coefficient management, directly simplifying firmware and reducing active CPU time.

Can the MPL3150A2 operate autonomously without continuous MCU supervision?

Yes. The MPL3150A2 supports autonomous data acquisition with a programmable interval from 1 second to 9 hours and stores up to 32 pressure/temperature samples in its embedded FIFO. Once configured, it can log data continuously while the host MCU remains in deep sleep - waking only upon INT1 or INT2 assertion for FIFO watermark, data-ready, or threshold events.

What are the power supply requirements for the MPL3150A2, and how do they impact system design?

The MPL3150A2 requires two independent supplies: VDD (1.95–3.6 V) for analog circuitry and VDDIO (1.62–3.6 V) for digital I²C interface. This separation allows interfacing with 1.8 V or 3.3 V MCUs without level shifters. Typical active current is 40 µA per measurement-second, and STANDBY current is just 2 µA - enabling efficient power budgeting in battery-powered designs using MPL3150A2.

Does the MPL3150A2 support user calibration to correct for mechanical stress after PCB mounting?

Yes. The MPL3150A2 includes volatile offset correction registers (Section 14.23 of the datasheet) that allow runtime adjustment of factory-programmed pressure and temperature offsets. This enables compensation for board-mount-induced drift (up to ±0.15 kPa), ensuring MPL3150A2 maintains its specified ±0.4 kPa accuracy without requiring external calibration equipment or rework.
