The article deals with a custom based integrated measurement unit
(IMU), which serves as processing device for MEMS based pressure
measurement.
The IMU consists of the three elementar stages, measurement
stage, processing stage and communication stage. They are
implemented on the one single board.
The measurement block has 16-bit resolution with 64 provided
measurement ranges to satisfy appropriate accuracy. The power
supply is 5 V, which allows to measure current with 238 nA step
within 1 mA measurement range.
The communication stage is based upon 12C standard.
