SSC-CB SSC Communication Board Datasheet Description Features The SSC Communication Board (SSC-CB) is part of the modular Interface fully compatible with USB 2.0 SSC Evaluation Kits. These kits provide hardware and software for Plug & play capability a very simple and intuitive method of evaluating IDTs sensor signal Power for the SSC Evaluation Kit provided by the USB port or * conditioner (SSC) families of ICs, including ZSC31xxx, ZSSC30xx , an external power supply as selected with a jumper setting ZSSC31xx, ZSSC41xx, and ZSSC5101. For the evaluation of Internal generation of all required voltage levels: 5VDC and different SSC ICs, only the IC-specific SSC Evaluation Board and 12VDC software are needed other parts of the kit hardware (the SSC Communication Board and if applicable, the SSC Sensor On-board galvanic isolation between the users computer and Replacement Board) are typically the same and interchangeable the Evaluation Kit hardware between different kits. The SSC-CB can also be used for communi- Access to all digital communication lines of the IDT SSC IC cation with the users SSC application module. being evaluated The SSC Communication Board V4.1 can provide the power Support for the ZSC31xxx, ZSSC30xx, ZSSC31xx, supply for the evaluation hardware and handle the communication ZSSC41xx, and ZSSC5101 SSC Evaluation Kits and the SSC with the users computer via a USB interface. To prevent mal- Mass Calibration System functioning or damage, a galvanic isolation to the computers USB Computer-controlled configuration and calibration via USB port is established on-board via digital isolators for the information interface simple, low cost lines and an isolated DC/DC converter for the power line. It is also USB port driver included in the Evaluation Kit setup software possible to supply the SSC-CB and connected kit boards or user simple installation 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 SSC Communication Board V4.1 terminal with a voltage of 1.0 to 3.6 VDC. A USB-UART device on the SSC-CB transfers all signals to the standardized USB port of the users 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. This document applies only to V4.1 of the SSC-CB. * The SSC-CB does not support the ZSSC30x6, ZSSC3218, or ZSSC3224 kits, which use different communications boards. 2019 Integrated Device Technology, Inc. 1 April 21, 2019 SSC-CB Datasheet Important Notes Disclaimer Integrated Device Technology, Inc. and its affiliated companies (herein referred to as IDT) shall not be liable for any damages arising out of defects resulting from (i) delivered hardware or software (ii) non-observance of instructions contained in this manual and in any other documentation provided to user, or (iii) misuse, abuse, use under abnormal conditions, or alteration by anyone other than IDT.
