HP03SA
Version: 1.0
. Integrated pressure sensor
. 300-1100hpa absolute Pressure Range
. 16 Bit Σ−Δ ADC
. 11 coefficients for software compensation
stored on chip
. I2C Serial Interface
. One system clock line (32768Hz)
. One hardware controlled reset line
. Low voltage, low power consumption
Description
The HP03 pressure module includes a piezo-resistive pressure sensor and an ADC
interface. It provides 16 bit word data for pressure and temperature related voltage. With
the help of a highly accurate calibration of the senor, 11 unique coefficients were stored
on the chip, thus accurate pressure and temperature reading can be realized. HM03 is a
low power, low voltage device with automatic power down switching. I2C Serial
Interface is used for communications with a microprocessor. Sensor packaging options
are DIP or SMD (with metal cap)
Features
. 15 Bit ADC resolution
. Supply voltage 2.2v-3.6v
. -20°C to + 60°C operating range
. No external components required
Applications
. Pressure measurement and control systems
. Mobile altimeter/barometer systems
. Weather forecast products
. Adventure or multi-mode watches
. GPS receivers

* XCLR is to reset the AD converter (active low). XCLR should be set to high only during AD
conversion phase(reading D1,D2), at all other states, such as reading calibration factors, this pin
should be kept low.
* The quality of the MCLK signal can significantly influence the current consumption of the
pressure module. To obtain minimum current, remember to supply good quality MCLK signal

Pressure and Temperature Measurement
The main function of HP03 system is to convert the uncompensated pressure and
temperature signal from a pressure sensor. After the conversion, the following two values
can be obtained:
. measured temperature
“D2”
. measured pressure
“D1”
As the sensor is strongly temperature dependent, it is necessary to compensate for these
effects. Therefore 10 sensor-specific coefficients are stored on the HP03 at our
manufacturing facility, and they allow an accurate software compensation in the
application.
The 7 coefficients are:
. Sensitivity coefficient
. Offset coefficient
. Temperature Coefficient of Sensitivity
. Temperature Coefficient of Offset
. Reference Temperature
. Temperature Coefficient of Temperature
. Offset Fine Tuning
