A user’s PC can communicate with a ZSC31014 socketed on the SSC Evaluation Board via an SSC Communication Board through a USB connection. The software should function on any Windows® 2000/XP/ Vista / Windows® 7 system after installation of a USB driver. Both the SSC Evaluation Board and the Sensor Replacement Board (SRB) can provide a replacement for a sensor. Only one of these can be used at a time for calibration as determined by the settings of jumpers K6 and K7 (see Figure 2.1). On the SRB, the sensor replacement is controlled by a potentiometer (see Figure 1.1). The SRB can be disconnected if the SSC Evaluation Board’s sensor replacement (artificial bridge stimulus) will be used. © 2016 Integrated Device Technology, Inc. 5 April 20, 2016 ZSC31014 Evaluation Kit Description 2 ZSC31014 SSC Evaluation Board 2.1. Overview The main purpose of the SSC Evaluation System is communication between the PC and the ZSC31014 (referred to as the DUT). The PC sends commands and data via the USB port on the CB (virtual com port). The 2 microcontroller on the SSC CB interprets these commands and relays them to the ZSC31014 in the I C bus standard format (K1 Pin 9/SCL Pin 11/SCK). The microcontroller will also forward any data bytes from the ZSC31014 back to the PC via the USB connection. These bytes can be bridge and temperature readings to be displayed by the PC software, raw ADC readings used during calibration, or EEPROM content bytes.

Connections to the ZSC31014 The SSC Evaluation Board has an SOP-8 socket for inserting the ZSC31014. Using the VDD, GND, SDA/MISO, SCL/SCLK and INT/SS/ connections on connector K5 on the SSC Evaluation Board, the board can be used for in-circuit programming of the ZSC31014 in the user’s calibration fixture. NOTE: Only one ASIC connection option can be used at a time. 2.3. Power Supply to the Board The K1 connector to the SSC CB provides the power supply from the SSC CB’s USB port to the SSC Evaluation Board. Using the power via the USB port, the maximum current that can be provided is 40mA. All functions of the board are operative down to 2.7V. The board has a red LED labeled D1, which lights if the board has power. The current consumption of the ZSC31014 can be measured by removing the jumper on 2-pin connector K9 and reading across the pins with an ammeter. 2.4. Reset Switch During operation, use the push button on the Communication Board to reset communications if needed. 2.5. Connecting a Customer Module to the SCC Evaluation Board A customer-specific sensor module usually includes a bridge sensor and a ZSC31014 contained in a protective casing. These modules provide access to Vdd, GND, SCL, and SDA pins via extended wires. These wires should be connected to the corresponding pins of K5 (refer to Figure 2.1; pins are indicated with green shading) on the ZSC31014 SSC Evaluation Board for evaluation and programming of the module. The packaged ZSC31014 chip must be removed from the IC socket when an external module is connected to the SSC Evaluation Board. A universal test board (refer to Figure 2.2) is also available for users who would like to use ZSC31014 in an SOP8 package and make connections to the ZSC31014 SSC Evaluation Board via pins on K5. The universal test board supports first test applications for IDT’s different SSOP/SOP packaging.

Connecting an External Bridge and External Temperature Sensor to the SSC Evaluation Board Use the Excel™ file ZSC31014_iLite_Ext_Temperature_Meas_RevX.x.xls to determine the value of the PTC. Follow these steps for connecting an external bridge and external temperature sensor to the SSC Evaluation Board: • • • • • • 3 Remove the SRB and open the jumpers on K5 and K6 (refer to Figure 2.1). Connect the external bridge to KL1: VBR, VINP and VINN. Important: Leave VSSB open. Connect the bridge bottom to the Bsink pin on K3. Short K3 VSSB to GND. Solder the top of the PTC resistor to pin 10 on terminal block K4 (BSINK). Solder the bottom of PTC resistor to pin 9 on terminal block K4 (VSS) Installing and Setting up the Software and USB Drivers 3.1. Installing the ZSC31014 iLiteTester™ Software The ZSC31014 SSC Evaluation Kit DVD contains a setup program (setup.exe), which automatically installs the iLiteTester™ software when clicked. Follow the dialog boxes to complete the installation, which automatically creates a shortcut on the PC desktop. Clicking this icon opens the ZSC31014 iLiteTester™ software for evaluating and calibrating ZSC31014 modules, which can also be used for the ZSC31014 SSC Mass Calibration Kit. Important: Before using the ZSC31014 iLiteTester™ software, install the USB drivers as described below. When the software is activated for the first time, the COM port must be selected and the ZSC31014 silicon revision must be entered as described in section 3.3 and 3.4. 3.2. Installing the USB Drivers The ZSC31014 SSC Evaluation Kit requires installation of two USB drivers. To install the drivers, the user’s system must meet these requirements: • • • • • 5x86-compatible PC 32 MB RAM Hard drive with 20MB free space USB port Windows® 2000/XP/ Vista / Windows® 7 The two required driver files are in the USB_Driver folder on the DVD. These drivers will make the PC’s USB port appear as a virtual COM port (typically COM3 or COM4 on most computers). The ZSC31014 iLiteTester™ software accesses the SSC Evaluation Board through the CB as if it were a COM (RS232) port. These drivers will not affect the operation of any other USB peripherals. Refer to SSC_AN_CommunicationBoard_Driver_Installation_Rev_X.xx.pdf for instructions on installing these two drivers and for determining the virtual COM port for the ZSC31014 SSC Evaluation Kit, which is needed for setting up the kit. © 2016 Integrated Device Technology, Inc. 8 April 20, 2016 ZSC31014 Evaluation Kit Description 3.3. “Find Com” on the Setup Menu After installing the software and the USB drivers, activate the software.

Overview The IDT software provided with the ZSC31014 SSC Evaluation Kit is intended for demonstration purposes and 2 calibration of single units. The installation folder is (C:\\program files\ZMDI\ZSC31014) . IDT can provide the user with algorithms and assistance in developing their full production calibration software. Five types of text files support the software user: 4.1.1. Log Files These files are saved in C:\\My Documents\ZMDI\ZSC31014 1 • When the software is activated and the communication port is opened, a CommLog.txt file is saved. This file is a log of the communication to the IC during the software session and can be saved after closing the software by renaming the file. Otherwise, it would be overwritten the next time the software is opened. • In Command Mode (CM) the user can save/load the EEPROM contents from a *.eep file to the EEPROM and vise versa. • In Normal Operation Mode (NOM) the user can log bridge and temperature readings to the DataLog.txt file. • The calibration is documented in the CalibrationLog.txt file, which is more convenient for users than the caldata.txt file. 4.1.2. Data File caldata.txt 2 The caldata.txt file is used by the software for calibration. Its structure is explained in Appendix B. Depending on the Windows system, the file is saved in one of the following locations: • for Windows 2000 and Windows XP in C:\\Documents and Settings\All Users\Application Data\ZMDI\ZSC31014 • for Windows Vista C:\\ProgramData\ZMDI\ZSC31014 4.2. Bridge and Temperature Display The software displays two large readout windows for temperature and bridge values (see Figure 4.1). The o temperature reading is the ZSC31014 temperature in C. The bridge reading is in %. Calibration determines the relationship of the % reading to the value the bridge is measuring. If the ZSC31014 has not been temperature calibrated, the displayed temperature is invalid. There is a continuous transmission of bridge readings and temperature readings. 2 For SW revisions
