MPL115A2 2 Miniature I C digital barometer, 50 to 115 kPa Rev. 10 — 10 October 2017 Data sheet: technical data 1 General description 2 The MPL115A2 is an absolute pressure sensor with a digital I C output targeting low cost applications. A miniature 5 x 3 x 1.2 mm LGA package is ideally suited for the space constrained requirements of portable electronic devices. Low current consumptions of 5 μA during Active mode and 1 μA during Shutdown (Sleep) mode are essential when focusing on low-power applications. The wide operating temperature range spans from – 40 °C to +105 °C to fit demanding environmental conditions. The MPL115A2 employs a MEMS pressure sensor with a conditioning IC to provide accurate pressure measurements from 50 to 115 kPa. An integrated ADC converts 2 pressure and temperature sensor readings to digitized outputs via a I C port. Factory calibration data is stored internally in an on-board ROM. Utilizing the raw sensor output and calibration data, the host microcontroller executes a compensation algorithm to render Compensated Absolute Pressure with ±1 kPa accuracy. The MPL115A2 pressure sensor’s small form factor, low power capability, precision, and digital output optimize it for barometric measurement applications. 2 Features • Digitized pressure and temperature information together with programmed calibration coefficients for host micro use. • Factory calibrated • 50 kPa to 115 kPa absolute pressure • ±1 kPa accuracy • 2.375 V to 5.5 V supply • Integrated ADC 2 • I C Interface (operates up to 400 kHz) 2 • 7-bit I C address = 60h • Monotonic pressure and temperature data outputs • Surface mount RoHS compliant package 3 Applications • Barometry (portable and desktop) • Altimeters • Weather stations • Hard-disk drives (HDD) • Industrial equipment • Health monitoring • Air control systems

[1] Use 4.7 kΩ pullup resistors for I2C communication. 7 Handling and Board Mount Recommendations The sensor die is sensitive to light exposure. Direct light exposure through the port hole can lead to varied accuracy of pressure measurement. Avoid such exposure to the port during normal operation. 7.1 Methods of Handling Components can be picked from the carrier tape using either the vacuum assist or the mechanical type pickup heads. A vacuum assist nozzle type is most common due to its lower cost of maintenance and ease of operation. The recommended vacuum nozzle configuration should be designed to make contact with the device directly on the metal cover and avoid vacuum port location directly over the vent hole in the metal cover of the MPL115A2 All information provided in this document is subject to legal disclaimers. © NXP B.V. 2017.

NXP Semiconductors MPL115A2 2 Miniature I C digital barometer, 50 to 115 kPa device. Multiple vacuum ports within the nozzle may be required to effectively handle the device and prevent shifting during movement to placement position. Vacuum pressure required to adequately support the component should be approximately 25 inches Hg (85 kPa). This level is typical of in-house vacuum supply. Pickup nozzles are available in various sizes and configurations to suit a variety of component geometries. To select the nozzle best suited for the specific application, it is recommended that the customer consult their pick and place equipment supplier to determine the correct nozzle. In some cases it may be necessary to fabricate a special nozzle depending on the equipment and speed of operation. Tweezers or other mechanical forms of handling that have a sharp point are not recommended since they can inadvertently be inserted into the vent hole of the device. This can lead to a puncture of the MEMS element that will render the device inoperable. 7.2 Board Mount Recommendations Components can be mounted using solder paste stencil, screen printed or dispensed onto the PCB pads prior to placement of the component. The volume of solder paste applied to the PCB is normally sufficient to secure the component during transport to the subsequent reflow soldering process. Use of adhesives to secure the component is not recommended, but where necessary can be applied to the underside of the device. Solder pastes are available in variety of metal compositions, particle size and flux types. The solder paste consists of metals and flux required for a reliable connection between the component lead and the PCB pad. Flux aids the removal of oxides that may be present on PCB pads and prevents further oxidation from occurring during the solder process. The use of a No-Clean (NC) flux is recommended for exposed cavity components. Using pressure spray, wire brush, or other methods of cleaning is not recommended since it can puncture the MEMS device and render it unusable. If cleaning of the pcb is performed, Water Soluble (WS) flux can be used. However, it is recommended the component cavity is protected by adhesive Kapton tape, vinyl cap or other means prior to the cleaning process. This covering will prevent damage to the MEMS device, contamination, and foreign materials from being introduced into device cavity as result of cleaning processes. Ultrasonic cleaning is not recommended as the frequencies can damage wire bond interconnections and the MEMS device.

A typical usage sequence is as follows: Initial power-up 2 All circuit elements are active. I C port pins are high impedance and associated registers are cleared. The device then enters standby mode. Reading coefficient data The user then typically accesses the part and reads the coefficient data. The main circuits within the slave device are disabled during read activity. The coefficients are usually stored in the host microcontoller local memory but can be re-read at any time. It is not necessary to read the values stored in the host microcontroller multiple times because the coefficients within a device are constant and do not change. However, note that the coefficients will be different from device to device, and cannot be used for another part. Data conversion This is the first step that is performed each time a new pressure reading is required which is initiated by the host sending the CONVERT command. The main system circuits are activated (wake) in response to the command and after the conversion completes, the result is placed into the Pressure and Temperature ADC output registers. The conversion completes within the maximum conversion time, tc (see row 7, in Table 10). The device then enters standby mode.

NXP Semiconductors MPL115A2 2 Miniature I C digital barometer, 50 to 115 kPa Compensated pressure reading After the conversion has been given sufficient time to complete, the host microcontroller reads the result from the ADC output registers and calculates the Compensated Pressure, a barometric/atmospheric pressure value which is compensated for changes in temperature and pressure sensor linearity. This is done using the coefficient data from the MPL115A and the raw sampled pressure and temperature ADC output values, in a compensation equation (detailed later). Note that this is an absolute pressure measurement with a vacuum as a reference. From this step the host controller may either wait and then return to the Data Conversion step to obtain the next pressure reading or it may go to the Shutdown step. Shutdown For longer periods of inactivity the user may assert the SHDN input by driving this pin low to reduce system power consumption. This removes power from all internal circuits, including any registers. In the shutdown state, the Pressure and Temperature registers will be reset, losing any previous ADC output values. This step is exited by taking the SHDN pin high. Wait for the maximum wakeup time, tw (see row 8, in Table 10), after which another pressure reading can be taken by transitioning to the data Conversion step.
