_32332628 Issue H_ ## MPR SERIES ## **MicroPressure Board Mount Pressure Sensors Compact, High Accuracy, Compensated/Amplified** ## DESCRIPTION The MPR Series is a very small piezoresistive silicon pressure sensor offering a digital output for reading pressure over the specified full scale pressure span and temperature range. It is calibrated and compensated over a specific temperature range for sensor offset, sensitivity, temperature effects, and non-linearity using an on-board Application Specific Integrated Circuit (ASIC). This product is designed to meet the requirements of higher volume medical (consumer and non-consumer) devices, commercial appliance, and industrial/HVAC applications. ## DIFFERENTIATION - Application-specific design addresses various application needs and challenges. - Digital output: Plug and play feature enables ease of implementation and system level connectivity. - Total Error Band: Provides a more comprehensive measurement of performance over the compensated temperature range, which minimizes testing and calibrating every sensor, thereby potentially reducing manufacturing cost; improves sensor accuracy and offers ease of sensor interchangeability due to minimal partto-part variation. (See Figure 1.) ## VALUE TO CUSTOMERS - Very small form factor: Enables - portability by addressing weight, size, and space restrictions; occupies less area on the PCB. - Wide pressure ranges simplify use. - Enhances performance: Output accelerates performance through reduced conversion requirements and direct interface to microprocessors. - Value solution: Cost-effective, higher volume solution with configurable options. - Meets IPC/JEDEC J-STD-020D.1 Moisture Sensitivity Level 1 requirements: Allows avoidance of thermal and mechanical damage during solder reflow attachment and/ or repair that lesser rated sensors may incur; allows long floor life when stored as specified (simplifying storage and reducing scrap); eliminates lengthy bakes prior to reflow, and allows for lean manufacturing due to stability and usability shortly after reflow. - Meets food safety certification for North America, Europe and Asia (see Table 2). ## POTENTIAL APPLICATIONS - Consumer medical: Non-invasive - blood pressure monitoring, negativepressure wound therapy, breast pumps, mobile oxygen concentrators, airflow monitors, CPAP water tanks, and medical wearables - Non-consumer medical: Invasive blood pressure monitors, ambulatory blood pressure measurement - Industrial: Air braking systems, gas and water meters - Consumer: Coffee machines, humidifiers, air beds, washing machines, dishwashers ## FEATURES - 5 mm x 5 mm [0.20 in x 0.20 in] package footprint - Calibrated and compensated - 60 mbar to 2.5 bar | 6 kPa to 250 kPa | - 1 psi to 30 psi - 24-bit digital I[2] C or SPI-compatible output - IoT (Internet of Things) ready interface - Stainless steel pressure port - Compatible with a variety of liquid media - Absolute and gage pressure types - Total Error Band after customer autozero: As low as ±1.25 %FSS - Compensated temperature range: 0ºC to 50ºC [32ºF to 122ºF] - REACH and RoHS compliant - Meets IPC/JEDEC J-STD-020D.1 Moisture Sensitivity Level 1 - Select sensors available on breakout board for easy evaluation and testing - Ultra-low power consumption (as low as 0.01 mW typ. average power, 1 Hz measurement frequency) - Sensor materials have been tested and certified for these food safety standards: - NSF-169 - BPA Free - LFGB **The MPR Series joins an extensive line of board mount pressure sensors for potential use in medical, industrial, and consumer applications.

TEB COMPONENTS FOR THE MPR SERIES Total Error Band (TEB) is a single specification that includes the major sources of sensor error. TEB should not be confused with accuracy, which is actually a component of TEB. TEB is the worst error that the sensor could experience. Honeywell uses the TEB specification in its datasheet because it is the most comprehensive measurement of a sensor’s true accuracy. Honeywell also provides the accuracy specification in order to provide a common comparison with competitors’ literature that does not use the TEB specification. Many competitors do not use TEB—they simply specify the accuracy of their device. Their accuracy specification, however, may exclude certain parameters. On their datasheet, the errors are listed individually. When combined, the total error (or what would be TEB) could be significant. ## **Sources of Error** |**Sources of Error**|| |---|---| |Offset|Total<br>Error<br>Band<br>**Accuracy**<br>**BFSL**| |Full Scale Span|| |Pressure Non-Linearity|| |Pressure Hysteresis|| |Pressure Non-Repeatability|| |Thermal Effect on Offset|| |Thermal Effect on Span|| |Thermal Hysteresis|| TABLE 1.

Upon receiving the user command, the sensor wakes up from Standby Mode, runs a measurement in Active State, and automatically returns to Standby Mode, awaiting the next command. The resulting sensor power consumption is a function of the sampling rate (samples per second) as shown in Tables 6 and 7 and Figures 2 and 3. TABLE 6.

The MPR Series sensor can begin the first measurement after 2.5 ms from when the VDD supply is operational. Alternatively, instead of a power-on reset, a reset and new power-up sequence can be triggered by an IC-reset signal (high low) at the RES pin. ## 4 .0 POWER SUPPLY REQUIREMENT Verify that system power to the sensor meets the VDD rising slope requirement (minimum VDD rising slope is at least 10 V/ms). If not, use the RES pin to bring the sensor out of reset once the system power has stabilized. 12 sensing.honeywell.com ## MICROPRESSURE BOARD MOUNT PRESSURE SENSORS, MPR SERIES ## 5 .0 REFERENCE CIRCUIT DESIGN ## 5 .1 I[2] C AND SPI CIRCUIT DIAGRAMS (SEE FIGURES 5 AND 6 .)

Sensing and Internet of Things 13 ## MICROPRESSURE BOARD MOUNT PRESSURE SENSORS, MPR SERIES ## 6 .0 I[2] C COMMUNICATIONS ## 6 .1 I[2] C BUS CONFIGURATION (SEE FIGURE 7 .) The I[2] C bus is a simple, serial 8-bit oriented computer bus for efficient I[2] C (Inter-IC) control. It provides good support for communication between different ICs across short circuit-board distances, such as interfacing microcontrollers with various low speed peripheral devices. For detailed specifications of the I[2] C protocol, see Rev. 6 (April 2014) of the I[2] C Bus Specification (source: NXP Semiconductor at https://www.nxp.com/docs/en/user-guide/UM10204.pdf). Each device connected to the bus is software addressable by a unique address and a simple Master/Sensor relationship that exists at all times. The output stages of devices connected to the bus are designed around an open collector architecture. Because of this, pull-up resistors to +VDD must be provided on the bus. Both SDA and SCL are bidirectional lines, and it is important to system performance to match the capacitive loads on both lines. In addition, in accordance with the I[2] C specification, the maximum allowable capacitance on either line is 400 pF to ensure reliable edge transitions at 400 kHz clock speeds. When the bus is free, both lines are pulled up to +VDD. Data on the I[2] C bus can be transferred at a rate up to 100 kbit/s in the standard-mode, or up to 400 kbit/s in the fast-mode. FIGURE 7 .

Following the address and read bit from the Master, the MPR Series Sensors are designed to output up to 4 bytes of data. The first data byte is the Status Byte (8-bit) and the second to fourth bytes are the compensated pressure output (24-bit). ## 6 .3 I[2] C SENSOR ADDRESS Each MPR Series I[2] C Sensor is referenced on the bus by a 7-bit sensor address. The default address for the MPR Series is 24 (0x18). Other available standard addresses are: 08 (0x08), 40 (0x28), 56 (0x38), 72 (0x48), 88 (0x58), 104 (0x68), 120 (0x78). (Other custom values are available. Please contact Honeywell Customer Service with questions regarding custom Sensor addresses.) ## 6 .4 I[2] C PRESSURE READING To read out a compensated pressure reading, the Master generates a START condition and sends the Sensor address followed by a read bit (1). After the Sensor generates an acknowledge, it will transmit up to 4 bytes of data. The first data byte is the Status Byte (8-bit) and the second to fourth bytes are the compensated pressure output (24-bit). The Master must acknowledge the receipt of each byte, and can terminate the communication by sending a Not Acknowledge (NACK) bit followed by a Stop bit after receiving the required bytes of data. 14 sensing.honeywell.com ## MICROPRESSURE BOARD MOUNT PRESSURE SENSORS, MPR SERIES ## 6 .5 I[2] C STATUS BYTE (SEE TABLE 15 .)

It operates either in full-duplex or half-duplex mode, allowing communication to occur in either both directions simultaneously, or in one direction only. The Master device initiates an information transfer on the bus and generates clock and control signals. Sensors are controlled by the Master through individual Sensor Select (SS) lines and are active only when selected. The MPR Series SPI sensors operate in full-duplex mode only, with data transfer from the Sensor to the Master. This data transmission uses four, unidirectional bus lines. The Master controls SCLK, MOSI and SS; the Sensor controls MISO. (See Figure 8.) FIGURE 8 .

At this point, the sensor is no longer idle, and will begin sending data once a clock is received. MPR Series SPI sensors are configured for SPI operation in mode 0 (clock polarity is 0 and clock phase is 0). (See Figure 9.) FIGURE 9 .

The first data byte is the Status Byte (8-bit) and the second to fourth bytes are the compensated pressure output (24-bit). ## 7 .3 SPI PRESSURE READING To read out a compensated pressure reading, the Master generates the necessary clock signal after activating the sensor with the Sensor Select (SS) line. The sensor will transmit up to 4 bytes of data. The first data byte is the Status Byte (8-bit) and the second to fourth bytes are the compensated pressure output (24-bit). The Master can terminate the communication by stopping the clock and deactivating the SS line.

Output = * (Pressure - Pmin.) + Outputmin. Pmax. - Pmin. Rearranging this equation to solve for Pressure, we get Equation 2: ## Equation 2: Pressure Output Function (Output - Outputmin.) * (Pmax.- Pmin.) Pressure = + Pmin. Outputmax. - Outputmin. Where: Outputmax. = output at maximum pressure [counts] Outputmin. = output at minimum pressure [counts] Pmax. = maximum value of pressure range [bar, psi, kPa, etc.] Pmin. = minimum value of pressure range [bar, psi, kPa, etc.] Pressure = pressure reading [bar, psi, kPa, etc.] Output = digital pressure reading [counts] Example: Calculate the pressure for a -1 psi to 1 psi gage sensor with a 10% to 90% calibration, and a pressure output of 14260634 (decimal) counts: Outputmax. = 15099494 counts (90% of 2[24] counts or 0xE66666) Outputmin. = 1677722 counts (10% of 2[24] counts or 0x19999A) Pmax. = 1 psi Pmin. = -1 psi Pressure = pressure in psi Output = 14260634 counts **==> picture [266 x 118] intentionally omitted <==** **----- Start of picture text -----**<br> (14260634-1677722) * (1 - ( - 1))<br>Pressure = + (-1)<br>15099494 - 1677722<br>25165824<br>Pressure = + (-1)<br>13421772<br>Pressure = 0.875 psi<br>**----- End of picture text -----**<br> Sensing and Internet of Things 19 ## MICROPRESSURE BOARD MOUNT PRESSURE SENSORS, MPR SERIES FIGURE 10 .

This cap can withstand lead-free, reflow temperatures and is intended to be removed after the end-user has completed assembly of the MPR sensor to the mating assembly. ## RECOMMENDED TUBING See Table 21 for recommended tubing information. ## RECOMMENDED O-RINGS See Figure 13 and Table 22 for O-Ring location, size and recommended part numbers. ## REFLOWABLE PROTECTIVE SILICONE CAP REMOVAL Removal of the cap may easily be done manually using ESD-safe tweezers; however, if possible, and to eliminate possible sensor protective gel damage, the cap removal process should be done in a semi-automated or automated manner. If the cap must be removed manually, follow this removal process: - Using ESD-safe tweezers, grasp the silicone cap midway up the straight port and lift the cap up vertically until it is no longer supported by the sensor housing. - At this point, stop the vertical movement and relieve the grasp of the tweezers. - Regrasp the cap in the unsupported area and continue the vertical movement until the cap is free and clear of the sensor’s protective gel. - Ensure that the sensor’s protective gel is not damaged during the cap removal process.
