MS5541C (RoHS*) MINIATURE 14 bar MODULE
DESCRIPTION
• 0 - 14 bar absolute pressure range
• 6 coefficients for a software compensation stored
on-chip
• Piezoresistive silicon micromachined sensor
• Integrated pressure sensor 6.2x6.4 mm
• 16 Bit ADC
• 3-wire serial interface
• 1 system clock line (32.768 kHz)
• Low voltage and low power consumption
• RoHS-compatible & Pb-free*
The MS5541C is the miniature version of MS5535C pressure sensor module. It contains a precision
piezoresistive pressure sensor and an improved version of the 16 Bit Micropower Sensor interface IC known
from the MS5535C. Compared to the previous version the ESD sensitivity has been improved to 4kV on all pins.
In addition to this the MS5541C 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 16 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 MS5541C is fully software compatible to the MS5535C and previous versions
of MS5541.
