ZSC31150 Functional Description MANUAL

2022-04-21

● The control logic of the ZSC31150 consists of the calibration microcontroller (CMC) and the control logic modules of the analog-to-digital (A/D) converter and serial digital interface. The configuration of the various modes of the device is done by programming an EEPROM.
● The CMC controls the measurement cycle and performs the calculations for sensor signal conditioning. This eliminates the gain deviation, the offset, the temperature deviation, and the non-linearity of the pre-amplified and A/D-converted sensor signal.
● Communication between the ZSC31150 and an external microcontroller, especially for calibration purposes, is done via a serial digital interface. Communication protocols according to the I2Cstandard are supported. A one-wire interface called OWI with the brand name ZACwire™ is also implemented. These serial interfaces are used for calibration of the sensor system consisting of a sensor transducer and the ZSC31150. The serial interface provides the read-out of the results of sensor signal conditioning as digital values during the calibration. The internal processing of received interface commands is done by the CMC. Therefore, the measurement cycle is interrupted if a command is received. Only the read-out of data is controlled by the serial interfaceitself and does not interrupt the CMC.
