I²C BUS
Introduction
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.
The HMI is capable to generate a digital output signal. The
device runs a cyclic program, which will store a corrected
pressure value with 12 bit resolution about every 250 µs
within the output registers of the internal ASIC. In order to
use the sensor for digital signal readout, it should be
connected to a bidirectional I²C-bus.
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 purpose. When acknowledge is missed, slave transmitter
becomes inactive. It is on master either to send last command again or to generate STOP condition in that case.
According to the I²C-bus 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 HMI is designed to work as a slave, hence
it will only respond to requests from a master device.
Digital I²C interface
Slave address: The I²C-bus master-slave concept requires
a unique address for each device. The HMI has a
preconfigured slave address (1111000xb). By factory
programming it is possible to define a secondary slave
address additional to the general one. According to I²C
specification 127 different addresses are available. The
sensor will then listen to both slave addresses. After
generating a START condition the master sends the
address byte containing a 7 bit address followed by a
data direction bit (R/W). A "0" indicates a transmission
from master to slave (WRITE), a "1" indicates a data
request (READ).
The HMI complies with the following protocol (Fig. 1):
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 condition. START conditions are always generated by the
master. Each initial request for a pressure value has to
begin with a START condition.
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 transmitted without generation of intermediate STOP condition.
DATA operation: The sensor starts to send 2 data bytes
containing the current pressure value as a 15 bit
information placed in the output registers.

Specification notes:
1. All wetted materials are selected to give a high level of media compatibility. Media compatibility refers to media inside the
pressure port and lid. Improved media compatibility on high pressure port (backward side of sensor chip) since media has no
contact to electronic components. Nevertheless tests with the media used in the specific application are recommended.
2. Sensor is calibrated in air, changes in sensor behaviour based on physical effects caused by the specific media can occur.
Weight of the media and wetting forces can influence the sensor characteristics.
3. Storage temperature of the sensor without package.
4. Proof pressure is the maximum pressure which may be applied without causing durable shifts of the electrical parameters
of the sensing element.
5. Full Scale Span (FSS) is the algebraic difference between the output signal for the highest and lowest specified pressure.
6. Non-linearity is the measured deviation based on Best Fit Straight Line (BFSL).
7. Accuracy is the combined error from non-linearity and hysteresis. Hysteresis is the maximum output difference at any point
within the operating pressure range for increasing and decreasing pressure.
8. Total accuracy is the combined error from offset and span calibration, non-linearity, pressure hysteresis, and temperature
effects. Calibration errors include the deviation of offset and full scale from nominal values.
9. Max. delay time between pressure change at the pressure die and signal change at the output.
10. Tested 1h, up to 85 °C.
Sensors are electronic components and should be handled only in ESD save environments.
