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. 2. Full Scale Span (FSS) is the algebraic difference between the output signal for the highest and lowest specified pressure. 3. Proof pressure is the maximum pressure which may be applied without causing durable shifts of the electrical parameters of the sensing element. 4. Burst pressure is the maximum pressure which may be applied without causing damage to the sensing element or leaks to the housing. 5. The HCE common mode pressure is 2 bar for all devices up to 500 mbar and 7 bar for all other devices. Common mode pressure is the maximum pressure that can be applied to both ports of a differential pressure sensor simultaneously without damaging the sensor housing. 6. Extended temperature ranges on request. Please contact First Sensor. 7. Max. delay time between pressure change at the pressure die and signal change at the output. 8. The response time depends on the adjusted internal A/D resolution of the sensor. For 14 bit it is typ. 1 ms. Other A/D resolutions and reponse times are available on request. Please contact First Sensor for further information. 9. Sensors with lower current consumption are available on request. Please contact First Sensor for further information.

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). Introduction The HCE is capable to generate a digital output signal. The device runs a cyclic program, which will store a corrected sensor value with 14 bit resolution about every 500 µs within the output registers of the internal ASIC. This cyclic program runs independent from the bus communication. In order to use the pressure sensor for digital signal readout, it should be connected to a SPI Master device. 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. 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. Data operation The MOSI line should always be set 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). 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.
