www.sensortechnics.com PRESSURE RANGES SPECIFICATIONS Specification notes: 1. If maximum burst pressure is exceeded, even momentarily, the package may leak or burst, or the pressure sensing die may fracture. 2. Full Scale Span (FSS) is the algebraic difference between the output signal for the highest and lowest specified pressure. 3. Total accuracy is the combined error from offset and span calibration, linearity, pressure hysteresis, and temperature effects. Linearity is the measured deviation based on a straight line. Hysteresis is the maximum output difference at any point within the operating pressure range for increasing and decreasing pressure. Calibration errors include the deviation of offset and full scale from nominal values. 4. Max. delay time between pressure change at the pressure die and signal change at the output. and reponse times are available on request. Please contact Sensortechnics for further information. 6. Maximum pressure on any port is the maximum operating plus common-mode pressure for differential pressure devices which can be applied without damaging the sensor. Common Mode Pressure is the pressure applied to both sides of the diaphragm simultaneously. traPr ebmune gnarerusserPt sruBe russerp 1 RA1160ECRr abm0011...006r ab2 UD520MECRr abm52...0r ab2.0 UD050MECRr abm05...0r ab53.0 UD001MECRr abm001...0r ab53.0 UD052MECRr abm052...0r ab1 UD005MECRr abm005...0r ab1 U)D,A(100BECRr ab1...0r ab2 U)D,A(200BECRr ab2...0r ab5 U)D,A(500BECRr ab5...0r ab01 BD010MECRr abm01±...0r ab2.0 BD520MECRr abm52±...0r ab2.0 BD050MECRr abm05±...0r ab53.0 BD001MECRr abm001±...0r ab53.0 BD052MECRr abm052±...0r ab1 BD005MECRr abm005±...0r ab1 BD100BECRr ab1±...0r ab2 RA6121ECRi sp61...21i sp03 UD010HECRH hcni01...0 2Oi sp3 UD100PECRi sp1...0i sp5 UD500PECRi sp5...0i sp51 U)D,A(510PECRi sp51...0i sp03 U)D,A(030PECRi sp03...0i sp07 U)D,A(001PECRi sp001...0i sp051 BD400HECRH hcni4±...0 2Oi sp3 BD010HECRH hcni01±...0 2Oi sp3 BD100PECRi sp1±...0i sp5 BD500PECRi sp5±...0i sp51 BD510PECRi sp51±...0i sp03

www.sensortechnics.com Introduction The RCE is capable to generate a digital output signal. The device runs a cyclic program, which will store a corrected sensor value with 12-bit resolution about every 250 µs within the output registers of the internal ASIC. This cyclic program runs independent from the bus communication. In order to use the RCE pressure sensor for digital signal readout, it should be connected to a SPI Master device. SPI specifies four signals: The clock (CLK) is generated by the master and input to all slaves. MOSI carries data from master to slave. MISO carries data from slave back to master. A slave select line (SS) allows individual selection of a slave device. SPI Modes A pair of parameters called clock polarity (CPOL) and clock phase (CPHA) determine the edges of the clock signal on which the data are driven and sampled. Each of the two parameters has two possible states, which allows for four possible combinations, all of which are incompatible with one another. In general the RCE series supports all combinations of clock phase (CPHA) and polarity (CPOL). By default it is programmed to CPHA = 0 and CPOL = 0, which means that data transmission starts with the rising first clock edge (see Fig 1). Slave select The falling edge of the SS line indicates the beginning of the transfer. Additionally the SS line must not be negated and reasserted between the three bytes to be transmitted. Data operation The MOSI is internally connected to high level. So there is no data transmission from master to slave. Because of internal configuration the slave will answer the first byte with an FFxh. The second and third byte contain the 15 bit pressure information (see Fig. 2).
