SSC Mass Calibration Board V2.1 Datasheet Description Features The SSC Mass Calibration System (MCS) enables simple and Multiple sensor module (DUT) access with support for the intuitive handling of calibration and evaluation of a larger number different digital interfaces of IDT SSC ICs of sensor systems based on IDTs Sensor Signal Conditioner ICs Interface to the users computer via a USB port via the SSC (SSCs). An evaluation of different mass calibration procedures for CB, which is also included in IDTs modular SSC Evaluation subsequent series production is possible earlier in the product Kits development phase. This allows an optimized product design that Each MCB interfaces up to 24 DUTs can meet the requirements of cost-effective mass manufacturing Up to 8 MCBs can be connected in series and are and mass calibration. addressable separately via one SSC CB, allowing The primary circuit board for the MCS is the Mass Calibration Board simultaneous calibration of up to 192 DUTs with one system (MCB), which communicates with the users computer via the SSC Separate power supplies for the MCB, the DUTs, and the I2C Communication Board (SSC CB). For each MCB, up to 24 devices bus is possible under test (DUTs) can be calibrated, and up to eight MCBs can be DUT analog output signal measurement connected in series to a single SSC CB, allowing mass calibration of up to 192 DUTs. PC-controlled plug & play mass calibration and configuration via USB interface simple, low cost Three digital interfaces are supported: I2C, one-wire interface (OWI), and Local Interconnect Network (LIN)*. The analog output Same ZSSCxxx Evaluation Software as for ZSSCxxxx voltage of each DUT can also be monitored and measured. The Evaluation Kits simple installation. user can adjust an individual board address manually, and each MCB can be controlled via the mass calibration software installed Contents on the users computer. Individual configuration and calibration of SSC Mass Calibration Board V2.1 DUTs is possible by multiplexing the power supply of the DUTs. The serial interface used by the DUTs is adjusted automatically via Software is available for download from the product page for software. If more than one MCB is used simultaneously, then these the Mass Calibration System (MCS) for the specific DUT adjustments must be identical for proper operation. product Jumper connectors on the MCBs provide access to all power lines. The DUTs are connected via standard connectors with The board can be supplied with 8 to 16 VDC via the on-board 5V mechanical locking linear regulator. To avoid overloading this single power supply line * The board uses LIN protocol at a voltage level of 5VDC. if heavy loads are driven, there are separate power supply interfaces for the MCB, the DUTs, and the I2C serial bus.

Restrictions in Use IDTs Mass Calibration System (MCS), consisting of the Communication Board (SSC CB), Mass Calibration Board (MCB), and the ZSSCxxxx Evaluation Software, is designed for sensor module evaluation, laboratory setup and the modules mass calibration development only. IDTs Mass Calibration System (MCS) must not be used for module production and production test setups. Firmware Compatibility The current version of the SSC CB is V4.1. For previous SSC CB versions, if the firmware version is earlier than V2.19a, the board will not be able to communicate with the SSC Mass Calibration Board V2.1. In this case, it is necessary update the firmware, which can be downloaded from www.IDT.com/SSC-MCB. For details about the update procedure, refer to the SSC Communication Board Application Note Firmware Updates available at www.idt.com/ssc-cb. Compatibility with Previous MCB Versions If the MCB V2.1 is to be used with a previous version MCB V2.0, refer to the ZSC31xxx/ZSSC3xxx MCS Application Note Mass Calibration Board Interaction (available upon request). Do not connect a previous version MCB V2.0 as the first MCB connected to the SSC CB. Contents 1.
