SSC-CB SSC Communication Board

2020-06-06
The SSC Communication Board (SSC-CB) is part of the modular SSC Evaluation Kits. These kits provide hardware and software for a very simple and intuitive method of evaluating IDT’s sensor signal conditioner (SSC) families of ICs, including ZSC31xxx,ZSSC30xx*, ZSSC31xx, ZSSC41xx, and ZSSC5101. For the evaluation of different SSC ICs, only the IC-specific SSC Evaluation Board and software are needed; other parts of the kit hardware (the SSC Communication Board and if applicable, the SSC Sensor Replacement Board) are typically the same and interchangeable between different kits.The SSC-CB can also be used for communi-cation with the user’s SSC application module.The SSC Communication Board V4.1†can provide the power supply for the evaluation hardware and handle the communication with the user’s computer via a USB interface. To prevent mal-functioning or damage, a galvanic isolation to the computer’s USB port is established on-board via digital isolators for the information lines and an isolated DC/DC converter for the power line. It is also possible to supply the SSC-C Band connected kit boards or user modules by an external power line (12V typical) via the KL1 screw terminal on the SSC-CB. It is also possible to supply low-voltage devices with a fixed 1.8 or 3.3 VDC internal voltage. Alternatively the connected application could be supplied via the KL2 screw terminal with a voltage of 1.0 to 3.6 VDC.A USB-UART deviceon the SSC-CB transfers all signals to the standardized USB port of the user’s computer. Its UART interface is connected via digital isolators with the UART of an on-board microcontroller that controls all functions of the Evaluation Kit and of the SSC IC to be evaluated. Its software allows direct communi-cation with the SSC IC via several interface options depending on the IC: I2C,SPI, ZACwire™(One-Wire Interface (OWI)), LIN via a discrete level shifter, or SENT. The microcontroller also controls the power lines (5VDC and two lines for 12VDC) by driving several electronic switches.The microcontroller displays the status of communication via LEDs. An on-board dual header strip enables access to all signal and power lines. This allows a simple signal check; e.g., by a digital oscilloscope, a multimeter, or a connection with user-specific hardware.Important:Always ensure that there is no power when connecting SSC Evaluation Kit boards.
