Product details
Overview
MPL015A2T1 from NXP Semiconductors (formerly Freescale) is a miniature I²C digital barometric pressure sensor in an LGA package, delivering absolute pressure measurement from 50 to 115 kPa with ±1 kPa accuracy at 25°C, 0.15 kPa resolution, and operation across –40°C to +105°C - ideal for portable altimeters and weather stations.
For engineers reviewing the MPL015A2T1 datasheet, MPL015A2T1 pinout, MPL015A2T1 application, or MPL015A2T1 equivalent, key selection criteria include its factory-calibrated I²C interface, ultra-low 5 μA active / 0.06 μA shutdown current, integrated ADC, and host-based temperature-compensated pressure calculation using stored coefficients.
Technical Context
The MPL015A2T1 integrates a MEMS pressure transducer with signal-conditioning IC and 10-bit ADC, outputting raw pressure and temperature codes via I²C (7-bit address 0x60). Compensation is executed externally by the host MCU using five factory-stored calibration coefficients (a₀, b₁, b₂, c₁₂).
It operates from 2.375 V to 5.5 V, supports standard-mode I²C up to 400 kHz, and features dedicated SHDN and RST pins for power management and communication control - enabling precise barometric sensing without on-device compensation logic.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar barometric pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BMP280 (Bosch) | Includes on-chip temperature compensation and SPI/I²C; higher accuracy (±0.12 hPa) but larger 2.0×2.0 mm package. | Reduces host MCU computation load; suited for space-constrained designs where self-compensation is preferred. | Select BMP280 if full compensated output is required without host algorithm implementation. |
| MS5637 (TE Connectivity) | Higher resolution (0.012 hPa), SPI-only interface, no SHDN pin; requires external voltage regulator. | Better for high-precision altimetry (e.g., drone stabilization); lacks integrated shutdown control for ultra-low-power duty cycles. | Choose MS5637 when sub-meter altitude resolution is critical and power management is handled externally. |
Compared with BMP280 and MS5637, the MPL015A2T1 offers the smallest footprint (5.0×3.0 mm), lowest shutdown current (0.06 μA), and explicit SHDN/RST pins - making it optimal for battery-powered, size-limited systems where host-based compensation is acceptable.

FAQ
What is the I²C address of the MPL015A2T1?
The MPL015A2T1 uses a fixed 7-bit I²C slave address of 0x60 (1100000b). It does not respond to the general call address (0x00). This address is hard-coded in silicon and cannot be modified, ensuring predictable firmware integration without address configuration overhead. The MPL015A2T1 supports standard-mode I²C up to 400 kHz with 4.7 kΩ pull-up resistors required on both SDA and SCL lines.
How is pressure compensation performed in the MPL015A2T1?
Compensation is executed externally by the host microcontroller using five factory-stored calibration coefficients (a₀, b₁, b₂, c₁₂) read from internal ROM addresses $04–$0B. The MPL015A2T1 outputs raw 10-bit pressure (Padc) and temperature (Tadc) ADC values; the host applies the formula Pcomp = a₀ + (b₁ + Padc + c₁₂×Tadc) × Padc + (b₂ + Tadc) × Tadc. The MPL015A2T1 itself performs no on-device compensation.
What is the purpose of the CAP pin on the MPL015A2T1?
The CAP pin on the MPL015A2T1 connects to an external 1 μF ceramic capacitor that stabilizes the internal voltage regulator and filters supply noise affecting ADC performance. This capacitor must be placed as close as possible to the CAP and VDD pins. Omitting or undersizing the capacitor degrades pressure measurement repeatability and increases noise in both pressure and temperature readings. The MPL015A2T1 will not meet its specified accuracy or resolution without proper CAP pin decoupling.
Does the MPL015A2T1 support continuous conversion mode?
No, the MPL015A2T1 does not support hardware-triggered continuous conversion. It operates in command-driven mode: the host issues a start convert command via I²C, then reads pressure and/or temperature data after the specified conversion time (≤1 ms for both). The MPL015A2T1 has no auto-repeat or streaming mode - each measurement requires explicit host initiation. This design minimizes power consumption and gives full timing control to the system MCU.
What is the maximum overpressure rating of the MPL015A2T1?
The MPL015A2T1 is rated for a maximum overpressure of 1000 kPa (≈10 atm), meaning it can withstand static pressure up to ten times its full-scale range without mechanical damage or permanent calibration shift. This rating ensures robustness during handling, reflow soldering, and transient pressure events in deployed systems. The MPL015A2T1 maintains its specified accuracy and reliability within its operational range of 50–115 kPa even after exposure to brief overpressure events within this limit.
