DESCRIPTIONThe TruStability ® Standard Accuracy Silicon Ceramic (SSC) Series is a piezoresistive silicon pressure sensor offering a ratiometric analog output for reading pressure over the specified full scale pressure span and temperature range.The SSC Series is fully calibrated and temperaturecompensated for sensor offset, sensitivity, temperature effects, and non-linearity using an on-board Application SpecificIntegrated Circuit (ASIC). Calibrated output values for pressure are updated at approximately 1 kHz.The SSC Series is calibrated over the temperature range of -20 C to 85 C [-4 F to 185 F]. The sensor is characterized for operation from a single power supply of either 3.3 Vdc or 5.0 Vdc.These sensors measure absolute, differential, and gage pressures. The absolute versions have an internal vacuum reference and an output value proportional to absolutepressure. Differential versions allow application of pressure to either side of the sensing diaphragm. Gage versions are referenced to atmospheric pressure and provide an output proportional to pressure variations from atmosphere.The TruStability ®pressure sensors are intended for use with non-corrosive, non-ionic gases, such as air and other dry gases. An available option extends the performance of these sensors to non-corrosive, non-ionic liquids.All products are designed and manufactured according to ISO 9001 standards.FEATURESIndustry-leading long-term stabilityExtremely tight accuracy of 0.25% FSS BFSL (Full ScaleSpan Best Fit Straight Line)Total error band of2% full scale span maximumModular and flexible design offers customers a variety of package styles and options, all with the same industry-leading performance specificationsMiniature 10 mm x 10 mm [0.39 in x 0.39 in] packageLow operating voltageExtremely low power consumptionRatiometric analog outputHigh resolution (min. 0.03 %FSS) Precision ASIC conditioning and temperature compensated over -20 C to 85 C [-4 F to 185F] temperature rangeRoHS compliantVirtually insensitive to mounting orientationInternal diagnostic functions increase system reliabilityAlso available with I 2C or SPI digital outputAbsolute, differential and gage typesPressure ranges from 1 psi to 150 psi (60 mbar to 10 bar)Custom calibration availableVarious pressure port options Liquid media option2 /sensingPOTENTIAL APPLICATIONS Medical:- Airflow monitors- Anesthesia machines - Blood analysis machines - Gas chromatography - Gas flow instrumentation - Kidney dialysis machines - Oxygen concentrators - Pneumatic controls - Respiratory machines - Sleep apnea equipment - VentilatorsIndustrial:- Barometry- Flow calibrators- Gas chromatography - Gas flow instrumentation - HVAC- Life sciences- Pneumatic controls1Honeywell Sensing and Control 3101. Absolute maximum ratings are the extreme limits the device will withstand without damage.2. Ratiometricity of the sensor (the ability of the device to scale to the supply voltage) is achieved within the specified operating voltage for eachoption.3. The sensor is not reverse polarity protected. Incorrect application of supply voltage or ground to the wrong pin may cause electrical failure.4. The compensated temperature range is the temperature range over which the sensor will produce an output proportional to pressure withinthe specified performance limits.5. The operating temperature range is the temperature range over which the sensor will produce an output proportional to pressure but may notremain within the specified performance limits.6. Accuracy: The maximum deviation in output from a Best Fit Straight Line (BFSL) fitted to the output measured over the pressure range at25 °C [77 °F]. Includes all errors due to pressure non-linearity, pressure hysteresis, and non-repeatability.7. Total Error Band: The maximum deviation from the ideal transfer function over the entire compensated temperature and pressure range.Includes all errors due to offset, full scale span, pressure non-linearity, pressure hysteresis, repeatability, thermal effect on offset, thermal effect on span, and thermal hysteresis.8. Full Scale Span (FSS) is the algebraic difference between the output signal measured at the maximum (Pmax.) and minimum (Pmin.) limits ofthe pressure range. (See Figure 1 for ranges.)9. Life may vary depending on specific application in which sensor is utilized. 10. Contact Honeywell Customer Service for detailed material information.CAUTIONPRODUCT DAMAGEEnsure liquid media is applied to Port 1 only; Port 2 is not compatible with liquids.Ensure liquid media contains no particulates. All TruStability ®sensors are dead-ended devices. Particulates can accumulate inside the sensor, causing damage or affecting sensor output.Recommend that the sensor be positioned with Port 1 facing downwards; any particulates in the system are less likely to enter and settle within the pressure sensor if it is in this position.Ensure liquid media does not create a residue when dried; build-up inside the sensor may affect sensor output. Rinsing of a dead-ended sensor is difficult and has limited effectiveness for removing residue.Ensure liquid media are compatible with wetted materials. Non-compatible liquid media will degrade sensor performance and may lead to sensor failure.Failure to comply with these instructions may result in product damage.4 /sensing11. The transfer function limits define the output of the sensor at a given pressure input. By specifying Pmin. and Pmax., the output at Pmin. andPmax., the complete transfer function of the sensor is defined. See Figure 2 for a graphical representation of the transfer function. Other transfer functions are available. Contact Honeywell Customer Service for more information.12. Digital outputs (SPI or I 2C) are also available.

The main function of theMS5525DSO is to convert the uncompensated analog output voltage from the piezo-resistive pressure sensor to a 24-bit digital value, as well as providing a 24-bit digital value for the temperature of the sensor. FACTORY CALIBRATIONEvery module is individually factory calibrated at two temperatures and three pressures. As a result, six coefficients necessary to compensate for process variations and temperature variations are calculated and stored in the 128-bit PROM of each module. These bits, partitioned into six coefficients, C1 through C6, must be read by the microcontroller software and used in the program converting D1 and D2 into compensated pressure and temperature values.The coefficients C0 and C7 are for factory calibration and CRC.SERIAL INTERFACEThe MS5525DSO has built in two types of serial interfaces: SPI and I2C. Pulling the Protocol Select pin PS to2C bus protocol.SPI MODEThe external microcontroller clocks in the data through the input SCLK (Serial CLocK) and SDI (Serial Data In). In the SPI mode module can accept both mode 0 and mode 3 for the clock polarity and phase. The sensor responds on the output SDO (Serial Data Out). The pin CSB (Chip Select) is used toenable/disable the interface, so that other devices can talk on the same SPI bus. The CSB pin can be pulled high after the command is sent or after the end of the command execution (for example end of conversion). The best noise performance from the module is obtained when the SPI bus is idle and without communication to other devices during the ADC conversion.I2C MODE & ADDRESSINGThe external microcontroller clocks in the data through the input SCL (Serial CLock) and SDA (Serial DAta). The sensor responds on the same pin SDA which is bidirectional for the I2C bus interface. So this interface type uses only 2 signal lines and does not require a chip select, which can be favorable to reduce board space. In I2C -Mode the complement of the pin CSB (Chip Select) represents the LSB of the I2C address. It is possible to use two sensors with two different addresses on the I2C bus. The pin CSB must be connected to VDD or GND do not leave these pins unconnected.COMMANDSThe MS5525DSO has only five basic commands:1. Reset2. Read PROM (128 bit of calibration words)3. D1 conversion4. D2 conversion5. Read ADC result (24 bit pressure / temperature)Size of each command is 1 byte (8 bits) as described in the table below. After ADC read commands the device will return 24 bit result and after the PROM read 16bit result. The address of the PROM is embedded inside of the PROM read command using the Ad2, Ad1 and Ad0 bits.structureFigure 2: Flow chart for pressure and temperature reading and software compensation.MEMORY MAPPINGFigure 3: Memory PROM Mapping Notes[1] Maximal size of intermediate result during evaluation of variable.SPI INTERFACERESET SEQUENCEThe Reset sequence shall be sent once after power-on to make sure that the calibration PROM gets loaded into the internal register. It can be also used to reset the device ROM from an unknown conditionCONVERSION SEQUENCEThe conversion command is used to initiate uncompensated pressure (D1) or uncompensated temperature (D2) conversion. The chip select can be disabled during this time to communicate with other devices.After the conversion, using ADC read command the result is clocked out with the MSB first. If the conversion is not executed before the ADC read command, or the ADC read command is repeated, it will give 0 as the output result. If the ADC read command is sent during conversion the result will be 0, the conversion will not stop and the final result will be wrong. Conversion sequence sent during the already started conversion process will yield incorrect result as well.PROM READ SEQUENCEThe read command for PROM shall be executed once after reset by the user to read the content of the calibration PROM and to calculate the calibration coefficients. There are in total 8 addresses resulting in a total memory of 128 bit. Address 0 contains factory data and the setup, addresses 1-6 calibration coefficients and address 7 contains the serial code and CRC. The command sequence is 8 bits long with a 16 bit result which is clocked with the MSB first.I 2C INTERFACECOMMANDSEach I 2C communication message starts with the start condition and it is ended with the stop condition. The MS5525DSO address is 111011Cx, where C is the complementary value of the pin CSB. Since the IC does not have a microcontroller inside, the commands for I 2C and SPI are quite similar.RESET SEQUENCEThe reset can be sent at any time. In the event that there is not a successful power on reset this may be caused by the SDA being blocked by the module in the acknowledge state. The only way to get the MS5525DSO to function is to send several SCLKs followed by a reset sequence or to repeat power on reset.Figure 10: I2C Reset CommandPROM READ SEQUENCEThe PROM Read command consists of two parts. First command sets up the system into PROM read mode. The second part gets the data from the system.Figure 11: I2C Command to read memory address= 011 (Coefficient 3)Figure 12: I2C response from MS5525DSOS = Start Condition W = Write A = Acknowledge P = Stop ConditionR = ReadN = Not AcknowledgeS = Start Condition W = Write A = Acknowledge P = Stop ConditionR = ReadN = Not AcknowledgeS = Start Condition W = Write A = Acknowledge P = Stop ConditionR = ReadN = Not AcknowledgeCONVERSION SEQUENCEA conversion can be started by sending the command to MS5525DSO. When command is sent to the system it stays busy until conversion is done. When conversion is finished the data can be accessed by sending a Read command, when an acknowledge appears from the MS5525DSO, 24 SCLK cycles may be sent to receive all result bits. Every 8-bit the system waits for an acknowledge signal.Figure 13: I 2C Command to initiate a pressure conversion (OSR=4096, typ=D1)Figure 14: I 2C ADC read sequenceFigure 15: I 2C response from MS5525DSOCYCLIC REDUNDANCY CHECK (CRC)MS5525DSO contains a PROM memory with 128-Bit. A 4-bit CRC has been implemented to check the data validity in memory.
