MS5540C
Miniature Barometer Module
SPECIFICATIONS
10 - 1100 mbar absolute pressure range
6 coefficients for software compensation stored on-chip
Piezoresistive silicon micromachined sensor
Integrated miniature pressure sensor 6.2 x 6.4 mm
16 Bit ADC
3-wire serial interface
1 system clock line (32.768 kHz)
Low voltage and low power consumption
The MS5540C is a SMD-hybrid device including a precision
piezoresistive pressure sensor and an ADC-Interface IC. It is a
miniature version of the MS5534C barometer/altimeter module
and provides a 16 Bit data word from a pressure and temperature
dependent voltage. MS5540C is a low power, low voltage device
with automatic power down (ON/OFF) switching. A 3-wire
interface is used for all communications with a micro-controller.
Compared to MS5534A the pressure range (measurement down
to 10 mbar) has been improved. The MS5540C is fully software
compatible to the MS5534C and previous versions of MS5540. In
addition, the MS5540C is from its outer dimensions compatible to
the MS54XX series of pressure sensors. Compared to the
previous version the ESD sensitivity level has been improved to
4kV on all pins. The gel protection of the sensor provides a water
protection sufficient for 100 m waterproof watches without any
additional protection.
