Pressure sensors with analog and digital output 2/9E / 11718 / A www.sensortechnics.com PRESSURE RANGES SPECIFICATIONS (VS = 5.0 VDC , TA = 25°C, analog output signal is ratiometric to VS, digital output signal is not ratiometric to VS) 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. Delay time between sampling and signal change at the output. 5. The smallest change in the output voltage, given any change in pressure. rebmuntraPe gnarerusserPe russerptsruB 1 ).pyt(ytivitisneS BD500HIBR5 ±...0 H" 2O isp 004.0 H" 2O 823 /stnuoc H" 2OBD010HIBR0 1±...03 0 02.04 61 UD010HIBR0 1...030 04.08 23 UA510PIBR5 1...0 )a(isp )a(isp 762.0 isp/V 812 /stnuoc isp UA030PIBR0 3...00 63 31.09 01 UA001PIBR0 01...00 510 40.03 3 U)D,G(100PIBR1 ...0 )g(isp )g(isp 00.47 723 U)D,G(500PIBR5 ...00 20 8.05 56 U)D,G(510PIBR5 1...00 37 62.08 12 U)D,G(030PIBR0 3...00 63 31.09 01 U)D,G(001PIBR0 01...00 510 40.03 3 BD100PIBR1 ±...0 )d(isp )d(isp 00.28 361 BD500PIBR5 ±...00 20 4.08 23 BD510PIBR5 1±...00 33 31.09 01 BD030PIBR0 3±...00 67 60.05 5 BD001PIBR0 01±...00 510 20.06 1

Pressure sensors with analog and digital output 5/9E / 11718 / A www.sensortechnics.com INTRODUCTION The RBI is capable to generate a digital output signal. It runs a cyclic program, which will store a corrected 12-bit sensor value about every 10 ms within the output registers of the internal ASIC. In order to use the pressure transducer for digital signal readout, the device should be connected to a bidirectional I²C-bus. According to the I²C-bus communication specification, the bus is controlled by a master device, which generates the clock signal, controls the bus access and generates START and STOP conditions. The RBI is designed to work as a slave, hence it will only respond to requests from a master device. The I²C-bus master-slave concept requires a unique address for each device. The RBI has a hard coded slave address (1111000xb), therefore it is not possible to access more than one RBI on the same I²C-bus line. DIGITAL I2C INTERFACE The RBI complies with the following protocol (FIGURE I): Bus not busy: During idle periods both data line (SDA) and clock line (SCL) remain HIGH. START condition (S): HIGH to LOW transition of SDA line while clock (SCL) is HIGH is interpreted as START con- dition. START conditions are always generated by the master. Each request for the current pressure value must be initiated with a START. STOP condition (P): LOW to HIGH transition of SDA line while clock (SCL) is HIGH determines STOP condition. STOP conditions are always generated by the master. More than one request for the current pressure value can be trans- mitted without generation of intermediate STOP condition. DATA valid (D): State of data line represents valid data when, after START condition, data line is stable for duration of HIGH period of clock signal. Data on line must be changed during LOW period of clock signal. There is one clock pulse per bit of data. Acknowledge (A): Data is transferred in pieces of 8 bits (1 byte) on serial bus, MSB first. After each byte receiving device – whether master or slave – is obliged to pull data line LOW as acknowledge for reception of data. Master must generate an extra clock pulse for this pur- pose. When acknowledge is missed, slave transmitter becomes inactive. It is on master either to send last com- mand again or to generate STOP condition in that case. Slave address: Each device connected to the bus has a unique slave address. After generating a START con- dition, the master has to transmit the slave address for the RBI with a READ command: $F1. The RBI must not be accessed with a WRITE command ($F0) as the correct function of the device can not be guaranteed in this case (note: a power-down power-up change will force the sensor to use factory data again). DATA operation: The RBI starts to send 2 data bytes containing the current pressure value placed in the output registers.
