MS5536C
SMD Gage Pressure Module
SPECIFICATIONS
Pressure range -400 to 1000 mbar
(Optional -1000 to 400 mbar)
0.1 mbar Resolution
Factory Calibrated (coefficients for software
compensation store on-chip)
3-wire serial interface
Low voltage / low power
MS5536C is a family of high-resolution factory calibrated
pressure sensors. The devices include a piezoresistive pressure
sensor and an ADC-Interface IC. The 3-wire serial interface
ensures simple communication with any microcontroller. The
devices provide digital pressure and temperature information as
16-Bit data word each. In addition 64-Bit of individually calibrated
compensation coefficients are stored allowing for a highly
accurate software compensation of process spread and
temperature effects.
The devices have a very low standby current and automatically
enter power down mode after each conversion. The optimum
compromise of refresh rate and average current consumption can
be defined by the application software.

NOTES
1) Storage and operation in an environment of dry and non-corrosive gases.
2) For a differential sensor, Differential Pressure is the difference of pressure at port 1 minus pressure at port 2.
For a gage sensor Differential Pressure is the difference of pressure at the port minus pressure of the ambient
air.
3) For a differential sensor Common Mode Pressure is the average of the pressure at port 1 and port 2. For a
gage sensor Common Mode Pressure is the average of the pressure at the port and the pressure of the
ambient air.

NOTES
1) Under the assumption of one conversion every second. Conversion means either a pressure or a temperature
measurement started by a command to the serial interface of MS5536C.
2) During conversion the sensor will be switched on and off in order to reduce power consumption; the total on
time within a conversion is about 2 ms. The current specified is active only during this time.
3) This value can be reduced by switching off MCLK while MS5536C is in standby mode.
4) Positive pressure corresponds to higher pressure at port 1 (nozzle port on plastic cap).
5) It is strongly recommended that a crystal oscillator be used because the device is sensitive to clock jitter. A
square-wave form of the clock signal is a must.
