4. Operation

4.1 General description

The SPL06-003 is designed to be connected directly to a microcontroller of a mobile

device via the I2C. Digital compensation of signal offset, sensitivity, temperature, and

non-linearity is accomplished via an 26-bit internal digital signal processor (DSP)

running a correction algorithm. Calibration coefficients are stored on-chip in a highly

reliable, nonvolatile, multiple-time programmable (MTP) memory.

4.2 General function and application schematics

The SPL06-003 consists of a MEMS pressure sensor with a conditioning IC to provide

accurate pressure measurement from 300 to 1100hPa.

Developed for correction of resistive bridge sensors, it can also provide a corrected

temperature output measured with an internal sensor. The measured and corrected

bridge values are provided at the digital output pins, which can be configured as I2C.

UP = pressure data (24 bit)

UT = temperature data (24 bit)

Figure 1: Typical application circuit

4.3 Measurement of pressure and temperature

The microcontroller sends a start sequence to start a pressure and temperature

measurement. After converting time, the result value (UP and UT) can be read via the

I2C interface. The compensation of sensor offset, sensitivity, temperature drift, and non-

linearity is accomplished via a Digital Signal Processing (DSP) unit running a correction

algorithm with calibration coefficients stored in an MTP memory. The SPL06-003’s

operational mode is being used typically in which the IC wakes up from a Sleep (low

power) State, runs a measurement in Active State and turns back automatically to the

Sleep State.

4.4 Calculating absolute altitude and calculating pressure at sea

level

With the measured pressure P and the pressure at sea level P0=1013.25hPa, the altitude

in meters can be calculated with the international barometric formula:

Altitude = 44330 × [𝟏 − (𝐏

P0)

𝟏𝟓.𝟐𝟓𝟓

.

]

Thus, a pressure change of Δp = 1hPa corresponds to 8.43m at sea level.

Figure 2: Transfer function: Altitude over sea level – Barometric pressure

With the measured pressure p and the absolute altitude the pressure at sea level can be

calculated:

P0 =𝑝

(1 −altitude44330 )

5.255

Thus, a difference in altitude of Δaltitude = 10m corresponds to 1.2hPa pressure change

at sea level.

4.5 Device and register address

The SPL06-003 module address is shown below. The LSB of the device address

distinguishes between read (1) and write (0) operation, corresponding to address 0xED

(read) and 0xEC (write).

4.6 I2C Interface

In I2C Mode, each command is started as shown in figure 4. Only the number of bytes

that is needed for the command has to be sent. After the execution of a command (busy

= 0) the expected data can be read as illustrated in figure 5. or if no data are returned by

the command the next command can be sent. The status can be read at any time as

described in figure 6.

All mandatory I²C-bus protocol features are implemented. Optional features like clock

stretching, 10-bit slave address, etc., are not supported by the SPL06-003’s interface.
