MS5541B (RoHS*) MINIATURE 14 bar MODULE
• Integrated pressure sensor 6.2x6.4 mm
• Pressure range 0 - 14 bar (200 PSI)
• 15 Bit ADC
• 6 coefficients for a software compensation stored
on-chip
• 3-wire serial interface
• 1 system clock line (32.768 kHz)
• Low voltage / low power
• RoHS-compatible & Pb-free*
DESCRIPTION
The MS5541B is the miniature version of the popular MS5535B pressure sensor module. It contains a precision
piezoresistive pressure sensor and an improved version of the 15 Bit Micropower Sensor interface IC known
from the MS5535B. Compared to the MS5535A the temperature range has been improved (-40 to +85°C).
Other improvements concern the ESD sensitivity, current consumption and converter accuracy. In addition to
this the MS5541B is from its outer dimensions compatible to the MS54xx series of pressure sensors. It uses an
antimagnetic polished stainless steel ring for sealing with O-ring. The sensor provides 15 Bit pressure and
temperature data via a 3 wire serial interface that can be easily interfaced with 4 Bit low power microcontrollers.
64 Bit of factory programmed PROM provides calibration data for a highly accurate pressure and temperature
calculation. The MS5541B is fully software compatible to the MS5535B and MS5535A.

• -40°C to +85°C
APPLICATIONS
• Small size 6.2x6.4 mm
• No external components required
• Diving computers and divers watches
• Mobile water depth measurement systems

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 MS5541B.
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 2ms.
3) This value can be reduced by switching off MCLK while MS5541B is in standby mode.
4) 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.
