Specification notes:
1. 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.
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.

HCE Series
Miniature amplified pressure sensors
SPI - SERIAL PERIPHERAL INTERFACE
In general the HCE 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).
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.
