ZSC31050 Mass calibration

Akoz

Hello,

We are considering using the ZSC31050 for temperature compensation of sensors.

Regarding a mass calibration setup, would the evaluation kit (ZSC31050KIT) be enough for simultaneous calibration of multiple sensors using an additional multiplexer ?

For example, we would connect multiple ZSC31050 using the SPI line and only switch the CS for adressing each of them individually.

Is the provided software capable of registering calibration data of multiple sensors at a given temperature or do we need to calibrate each ZSC31050 at a time ? 

Thank you for your time,

Best regards,

    Hello Akoz,

    Thanks for your request and for reaching out our Community.

    Please let me check this internally and get back to you as soon as possible.

    Hello Akoz,

    yes you can apply parallel calibration for multiple DUTs, the evaluation SW supports the mass calibration system, but only for the interfaces I2C and OWI. SPI is not supported and, also adding the CS signal and additional multiplexers won't be enough, since the MISO and MOSI are not routed on the MCB.

    Hello Kornelius,

    Thank you for your answer.

    You are mentionning the MCB and it is good to know that this is compatible with the evaluation software.

    However, the idea behind my question was to use the SSC board provided in the evaluation kit which has accessible pins and adding a multiplexer to calibrate multiple DUTs without the need of the MCB. If SPI is an issue, I guess the same principle could be applied with I2C or OWI.

    Thank you again for you time,

    Best regards,

    Hello Akoz,

    my first answer may have been misleading, so here again are the options you have with the communication board (CB) and evaluation SW:

    • The 31050 evaluation SW supports the mass calibration system for OWI and I2C. The mass calibration HW can be ordered via the homepage.
    • The evaluation SW supports SPI communication for the evaluation board. You can use it for single DUT calibration, one at a time.
    • You can also use our CB for your own HW/SW solution with SPI communication. To do this, you would need to create your own mass calibration board, where the SPI signals are multiplexed. Additionally, you would require your own software implementation for this multiplexed SPI communication and data management for the calibration. We provide a syntax document for using the CB, which outlines the basic string commands sent to the CB which converts them into complete SPI sequences.

    Examples:

    Sending the command to the CB "SW_002CAFE", is translated into an SPI write sequence from CB to DUT, writing two bytes: 0xCA and 0xFE

    Sending the command to the CB "SR_005", is translated into an SPI read sequence that reads 5 bytes from the DUT

    Hello Kornelius,

    Thank you for your detailled answer, everything looks clear to me now.
