Specification notes:
1. Proof pressure is the maximum pressure which may be applied without causing durable shifts of the electrical parameters of the
sensing element.
2. Burst pressure is the maximum pressure which may be applied without causing damage to the sensing element or leaks to the
housing.
3. Full Scale Span (FSS) is the algebraic difference between the output signal for the highest and lowest specified pressure.
4. 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.
5. Extended temperature ranges on request. Please contact First Sensor.
6. Max. delay time between pressure change at the pressure die and signal change at the output.
7. The response time depends on the adjusted internal A/D resolution of the sensor. For 12 bit it is typ. 0.5 ms. Other A/D resolutions
and reponse time are available on request. Please contact First Sensor for further information.
8. Sensors with lower current consumption are available on request. Please contact First Sensor for further information.

Amplified pressure sensors
I²C BUS
Introduction
The HDI 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.
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 HDI is designed to work as a slave, hence
it will only respond to requests from a master device.
Digital I²C interface
The HDI 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 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 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.
Slave address: The I²C-bus master-slave concept
requires a unique address for each device. The HDI 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).
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.
