The MS5607-02BA is a new generation of high resolution
altimeter sensors from MEAS Switzerland with SPI and I
2
C bus
interface. This barometric pressure sensor is optimized for
altimeters and variometers with an altitude resolution of 20 cm.
The sensor module includes a high linearity pressure sensor and
an ultra low power 24 bit ΔΣ ADC with internal factory calibrated
coefficients. It provides a precise digital 24 bit pressure and
temperature value and different operation modes that allow the
user to optimize for conversion speed and current consumption. A
high resolution temperature output allows the implementation of
an altimeter/thermometer function without any additional sensor.
The MS5607-02BA can be interfaced to virtually any
microcontroller. The communication protocol is simple, without the
need of programming internal registers in the device. Small
dimensions of only 5.0 mm x 3.0 mm and a height of only 1.0 mm
allow for integration in mobile devices. This new sensor module
generation is based on leading MEMS technology and latest
benefits from MEAS Switzerland proven experience and know-
how in high volume manufacturing of altimeter modules, which
have been widely used for over a decade. The sensing principle
employed leads to very low hysteresis and high stability of both
pressure and temperature signal.

FUNCTIONAL DESCRIPTION
Figure 1: Block diagram of MS5607-02BA
GENERAL
The MS5607-02BA consists of a piezo-resistive sensor and a sensor interface IC. The main function of the MS5607-
02BA is to convert the uncompensated analogue output voltage from the piezo-resistive pressure sensor to a 24-
bit digital value, as well as providing a 24-bit digital value for the temperature of the sensor.
FACTORY CALIBRATION
Every module is individually factory calibrated at two temperatures and two pressures. As a result, 6 coefficients
necessary to compensate for process variations and temperature variations are calculated and stored in the 128-
bit PROM of each module. These bits (partitioned into 6 coefficients) must be read by the microcontroller software
and used in the program converting D1 and D2 into compensated pressure and temperature values.
SERIAL INTERFACE
The MS5607-02BA has built in two types of serial interfaces: SPI and I
2
C. Pulling the Protocol Select pin PS to low
selects the SPI protocol, pulling PS to high activates the I
2
C bus protocol.

SPI MODE
The external microcontroller clocks in the data through the input SCLK (Serial CLocK) and SDI (Serial Data In). In
the SPI mode module can accept both mode 0 and mode 3 for the clock polarity and phase. The sensor responds
on the output SDO (Serial Data Out). The pin CSB (Chip Select) is used to enable/disable the interface, so that
other devices can talk on the same SPI bus. The CSB pin can be pulled high after the command is sent or after the
end of the command execution (for example end of conversion). The best noise performance from the module is
obtained when the SPI bus is idle and without communication to other devices during the ADC conversion.

I
2
C MODE
The external microcontroller clocks in the data through the input SCLK (Serial CLocK) and SDA (Serial DAta). The
sensor responds on the same pin SDA which is bidirectional for the I
2
C bus interface. So this interface type uses
only 2 signal lines and does not require a chip select, which can be favourable to reduce board space. In I
2
C-Mode
the complement of the pin CSB (Chip Select) represents the LSB of the I
2
C address. It is possible to use two sensors
with two different addresses on the I
2
C bus. The pin CSB shall be connected to VDD or GND (do not leave
unconnected!).
COMMANDS
The MS5607-02BA has only five basic commands:
1. Reset
2. Read PROM (128 bit of calibration words)
3. D1 conversion
4. D2 conversion
5. Read ADC result (24 bit pressure / temperature)

SECOND ORDER TEMPERATURE COMPENSATION
In order to obtain best accuracy over temperature range, particularly in low temperature, it is recommended to
compensate the non-linearity over the temperature. This can be achieved by correcting the calculated temperature,
offset and sensitivity by a second order correction factor and will be recalculated with the standard calculation. The
second-order factors are calculated as follows:

CONVERSION SEQUENCE
The conversion command is used to initiate uncompensated pressure (D1) or uncompensated temperature (D2)
conversion. The chip select can be disabled during this time to communicate with other devices.
After the conversion, using ADC read command the result is clocked out with the MSB first. If the conversion is not
executed before the ADC read command, or the ADC read command is repeated, it will give 0 as the output result.
If the ADC read command is sent during conversion the result will be 0, the conversion will not stop and the final
result will be wrong. Conversion sequence sent during the already started conversion process will yield incorrect
result as well.

PROM READ SEQUENCE
The read command for PROM shall be executed once after reset by the user to read the content of the calibration
PROM and to calculate the calibration coefficients. There are in total 8 addresses resulting in a total memory of 128
bit. Address 0 contains factory data and the setup, addresses 1-6 calibration coefficients and address 7 contains
the serial code and CRC. The command sequence is 8 bits long with a 16 bit result which is clocked with the MSB
first.

COMMANDS
Each I
2
C communication message starts with the start condition and it is ended with the stop condition. The
MS5607-02BA address is 111011Cx, where C is the complementary value of the pin CSB. Since the IC does not
have a microcontroller inside, the commands for I
2
C and SPI are quite similar.
RESET SEQUENCE
The reset can be sent at any time. In the event that there is not a successful power on reset this may be caused by
the SDA being blocked by the module in the acknowledge state. The only way to get the MS5607-02BA to function
is to send several SCLKs followed by a reset sequence or to repeat power on reset.

CONVERSION SEQUENCE
A conversion can be started by sending the command to MS5607-02BA. When command is sent to the system it
stays busy until conversion is done. When conversion is finished the data can be accessed by sending a Read
command, when an acknowledge appears from the MS5607-02BA, 24 SCLK cycles may be sent to receive all
result bits. Every 8 bit the system waits for an acknowledge signal.

MOUNTING AND ASSEMBLY CONSIDERATIONS
SOLDERING
Please refer to the application note AN808 available on our website for all soldering issues.
MOUNTING
The MS5607-02BA can be placed with automatic Pick & Place equipment using vacuum nozzles. It will not be
damaged by the vacuum. Due to the low stress assembly the sensor does not show pressure hysteresis effects. It
is important to solder all contact pads.
CONNECTION TO PCB
The package outline of the module allows the use of a flexible PCB for interconnection. This can be important for
applications in watches and other special devices.
CLEANING
The MS5607-02BA has been manufactured under cleanroom conditions. It is therefore recommended to assemble
the sensor under class 10’000 or better conditions. Should this not be possible, it is recommended to protect the
sensor opening during assembly from entering particles and dust. To avoid cleaning of the PCB, solder paste of
type “no-clean” shall be used. Cleaning might damage the sensor!
ESD PRECAUTIONS
The electrical contact pads are protected against ESD up to 4 kV HBM (human body model). It is therefore essential
to ground machines and personnel properly during assembly and handling of the device. The MS5607-02BA is
shipped in antistatic transport boxes. Any test adapters or production transport boxes used during the assembly of
the sensor shall be of an equivalent antistatic material.
DECOUPLING CAPACITOR
Particular care must be taken when connecting the device to the power supply. A 100 nF ceramic capacitor must
be placed as close as possible to the MS5607-02BA VDD pin. This capacitor will stabilize the power supply during
data conversion and thus, provide the highest possible accuracy.
