6 Each MCB is capable of communicating with and calibrating up to 24 ZSC31014 RBic ilite modules using the I 2 C protocol bi-directionally. Each of the DUT connectors on each MCB has the pin assignment shown in Figure 2.2. Note the orientation of the key. HV_DUT and OWI_ZACwire are not used for the ZSC Figure 2.2 Pin Assignments for DUT Connectors on the MCB VDDA SCL SDA HV_DUT OWI/ZACwire GND GND GND GND GND Note The SPI output setting cannot be used with the MCB, although the output mode can be programmed to SPI after calibration validation using the I 2 C protocol. Up to 8 MCBs with identical settings (except the address settings) can be connected in series and controlled by one CB. The address for each board must be assigned manually via jumper K4 starting with address 000 and numbered in ascending order. Each board must be connected separately to an external main power supply in the range of 8V to 16V DC. By multiplexing the power supply of each DUT, an individual configuration and calibration is possible.

Assign remaining MCBs in ascending order. See labels on board for bit assignments for jumpers. To power the DUTs with the internal MCB 5V supply, put the K14 jumper on Int(5P) and apply the MCB board power (8V to 16V DC) to Board Supply (KL1). To use a separate (lower) supply voltage for the DUTs, put the K14 jumper on extern and connect the DUT supply to VDD_DUT (KL2). Apply MCB board power (8V to 16V DC) to Board Supply (KL1). Use this setting to power the bus with the internal MCB 5V supply. Use this setting to use a separate (lower) supply voltage for the bus. Connect the bus supply to I 2 C Power (KL3). 6 of 21

7 Jumper/ Connector C-IF_in (Connector K2) C-IF_out (Connector K3) Connectors DUT 01 Required Setting or Connections Connect to CB or previous MCB. Connect to next MCB. Connect to MCRs or user-provided modules. Comments For first MCB, connection to the Communication Board (CB). For remaining MCBs, connect to previous MCB. Connect to next MCB. For remaining MCBs, connect to next MCB. Insert MCRs or user-provided modules # 01 through # 24 in DUT connectors # 01 through # 24 (also called port # ) The MCBs are connected in series to the Communication Board (CB).The CB interfaces to the host PC through a USB connection for serial communications. The PC sends commands and data via the USB (virtual COM port). The Controller on the board interprets these commands and relays them in the I 2 C format to one selected unit of the up to 192 ZSC31014 RBic ilite modules. The Controller also forwards any data bytes from the selected RBic ilite module back to the PC via the USB connection. Reset Button Hit the RESET button on the CB to reset the µcontroller on the MCBs Preparing the MCBs Important: Do not connect the USB cable or turn on the MCB power supplies until directed in the steps below. Set up each MCB with the proper jumper settings given in Table 2.1 and connect all the MCBs together in series in ascending order. Remember that all MCBs must have identical setting except for the address setting. Connect the first MCB to the CB as shown Figure 1.1. Insert the MCRs (see section 2.4) or user-provided sensor modules (see section 2.3 regarding supplies) to be calibrated in the DUT connectors 01 to 24. Connect the power supplies to all MCBs, but do not turn them on yet. Connect the CB to the PC using a USB cable. Verify that the green PWR LED is lit on the CB. Turn on the power supplies for the MCBs and if applicable, the DUT s separate power supplies Connections to ZSC31014 RBic ilite Sensor Modules The MCB provides direct connections to the sensor modules containing the ZSC31014 RBic ilite ICs (DUTs) via flat cable connectors if the module supply voltage is 5.5V and less. For supply voltages less than 5V, a separate voltage supply is needed (screw terminal KL2 on MCB; see Table 2.1). The labels on the board near the DUT connectors indicate the DUT numbering. 7 of 21

8 2.4. ZSC31014 Mass Calibration Reference Board (MCR) The Mass Calibration Board comes with four ZSC31014 MCRs. The MCR simulates a typical application circuit, 2 which allows checking the I C communication and simulating a 2-point calibration with the K2 jumper on the MCR shorted for the first calibration point and then open for the second point. Refer to section 4.3 for procedures for a dry-run calibration using the MCRs after reviewing the calibration example given in section 4.1. Figure 2.3 ZSC31014 MCR ZSC of 21

9 3 Installing and Setting up the Software 3.1. Installing the ZSC31014 ilitetester Communications and Calibration Software ZMDI s RBic ilite SSC Evaluation Kit DVD contains a setup program (setup.exe), which will automatically install the software when clicked. Follow the dialog boxes to complete the installation, which automatically creates a program shortcut on the PC desktop. Clicking this icon opens the ZSC31014 ilitetester software for evaluating and calibrating RBic ilite modules. The SSC Mass Calibration Kit can use the same software as the single-unit ZSC31014 ilite SSC Evaluation Kit, which includes the additional support for the MCB Installing the USB Drivers Before using the ZSC31014 ilitetester software, install the two USB drivers available in the USB_Driver folder on the ZSC31014 ilitetester DVD. To install the drivers, the user s system must meet these requirements: x86-compatible PC 64 MB RAM Hard drive with 20MB free space USB port Windows 2000/XP/ Vista / Windows 7 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 MCB 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_x.pdf for instructions on installing these two drivers and for determining the virtual COM port for the MCS, which is needed for setting up the software in the next section Setting up the ilitetester Software After setting up the hardware as described in section 2, open the ZSC31014 ilitetester software. Complete these steps to set up the program: Select the ZSC31014 IC revision by clicking the Setup pull-down menu, then Change IC Rev. See Figure 3.1. In the Port field, enter the correct COM port to use for the PC SSC MCB communication via USB. If the correct setting is unknown, click the Setup pull-down menu, then Find COM, and respond to the resulting dialog box by accept/continue searching until communication is established as indicated in the Status window. If needed for the time constraints of the user s equipment, use the Power Down Time setting under Setup to select 20ms or 100ms as the power down time. 9 of 21

10 Figure 3.1 Main Dialog Window of the ZSC31014 ilitetester Software Click here to find the COM port using the resulting dialog box. Click here to select the ZSC31014 part revision (marked on the package) Special Option Power Up all DUTs The Power up all DUTs option under the Setup menu shown in Figure 3.1 is valid for the MCS only. When this option is selected, all devices will be powered up regardless of which module is currently being used. This can be beneficial if the connected sensor has a warm-up period. It is possible for this option to cause problems when entering Command Mode. If communication is erratic or failing outright, unselect this option. 10 of 21

11 4 Calibration via the SSC MSC & ZSC31014 ilitetester Software 4.1. Software Overview The ZMDI software provided with the SSC MCS is intended for demonstration purposes and calibration of multiple units. ZMDI can provide the user with algorithms and assistance in developing their full production calibration software. The installation folder is (C:\\Program Files\ZMDI\ZSC31014) 2. ZMDI can provide the user with algorithms and assistance in developing their full production calibration software. There are five types of text files that support the software user as described in sections 4.1.1and Log Files These files are saved in [My Documents]\ZMDI\ZSC 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 will be opened. In Command Mode (CM) the user can save/load the EEPROM contents from a SaveSettings.txt 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_DDMMYYYY.txt file, which is more convenient for users than the caldata.txt file Data File caldata.txt The caldata.txt file is used by the software for calibration. Its structure is explained in Appendix B of ZSC31014_iLite_SSC_Evaluation_Kit_revX.x.pdf. Where the caldata.txt file is saved depends on the Windows System: 2 For Windows 2000 and Windows XP in C:\Documents and Settings\All Users\Application Data\ZMDI\ZSC31014 For Windows Vista and Windows 7 C:\ProgramData\ZMDI\ZSC Calibration Sequence Although the ZSC31014 RBic ilite can function with many different types of resistive bridges, assume it is connected to a pressure bridge for the following calibration example. In this case, calibration essentially involves collecting raw bridge and temperature data from the ZSC31014 RBic ilite for different known pressures and temperatures. This raw data can then be processed by the calibration master (the PC), and the calculated coefficients can then be written to the EEPROM of the RBic ilite. The ZSC31014 ilitetester software ZMDI provides with this board is intended for demonstration purposes and calibration of single/multiple units. ZMDI can provide customers with algorithms and assistance in developing their full production calibration software. 2 For SW revisions < 1.94, this file was saved in C:\Program Files\ZMD America\RBic ilite Tester. 11 of 21

12 The ZSC31014 ilitetester software handles collecting data, storing it in a database on the calibration PC, and using it to calculate and write calibration coefficients to EEPROM. During this process, it generates a unique identification number for the ASIC, which is programmed in EEPROM and can be used as an index in the database. This database will contain all the raw values of bridge readings and temperature readings for that part, as well as the known pressure and temperature to which the bridge was exposed depending on the prior selected calibration method and/or individual selectable calibration coefficients. There are three main steps to calibration: 1. Assigning the unique identification to the RBic ilite and selecting the configuration settings. 2. Collecting data. Data collection involves getting raw data from the bridge at different known pressures and temperatures. This data is then stored on the calibration PC using the unique identification of the ZSC31014 RBic ilite DUT as the index into the database. 3. Calculating and writing coefficients to EEPROM. After enough data points have been collected to calculate all the desired coefficients, the coefficients can be calculated by the calibrating PC and written to the EEPROM of the ZSC31014 RBic ilite. Step 1 Assigning a Unique Identification (Initialization Section) Click the Calibration button on the main screen. On the resulting calibration screen (see Figure 4.1), enter the number of sensor modules (1-192) connected to the Mass Calibration Boards in the Start # and NUM ASICs fields in the upper left corner, which will be activated when the Mass Calibration Board is being used. 12 of 21

13 Figure 4.1 Initialization for 3 DUTs in the Calibration Window Enter first DUT number here (1-192). Then click here to initialize. Enter number of DUTs here (1-192). Status of initialization ID numbers used during calibration In the top middle of the calibration screen (see Figure 4.1), click on Initialize. In the resulting dialog box (see Figure 4.3), verify or correct the configuration for the ZSC31014 RBic ilite under test. Complete the Bridge fields in the Front End Configuration section. If a temperature calibration method is selected, also complete the Temp section. The default values shown in this dialog window are the previous settings and can differ from the actual EEPROM contents, which will be overwritten by clicking the OK button. The part is assigned a unique ID, which is used as an index in the database caldata.txt, which stores the chamber and raw readings for each part for each of the calibration points (see section 4.1.2). This unique ID is also programmed into the EEPROM Cust_ID0, Cust_ID1, and Cust_ID2 registers. If using Revision D silicon, the Wafer #, Lot #, and X Y Coordinates are used for the unique ID. The software automatically loads and writes unity values for Gain_B and Gain_T to the EEPROM and sets the Offset_B to an A2D_Offset related value. All other coefficients are set to zero. The raw data are collected with these settings in NOM. 13 of 21

14 When the MCB is being used, these initialization commands are applied to all sensor modules currently connected. Note: It is assumed that the sensors being calibrated are well understood and that the user has previously calibrated units using the ZSC31014 ilite SSC Evaluation Kit and has determined which A2D offset mode(s) are best suited for this sensor. Step 2 Data Collection Common Calibration Type Menu Next, select the type of calibration required from the Common Calibration Type pull-down menu in the top right of the calibration screen. The number of unique points (for this example, pressure and temperature points) at which calibration must be performed depends on the user s requirements. The minimum is a 2-point calibration, and the maximum is a 7-point calibration. Depending on the number of calibration temperature points, a linear or second order temperature correction is performed with 2 or 3 (respectively) temperature coefficients (Offset_T&Gain_T or Offset_T&Gain_T&SOT_T). In the left section of the calibration screen there is a graph (X-axis = Temperature, Y-axis = Bridge). This graph outlines the recommended spread of points (pressure for this example and temperature) to be used for calibration. Based on statistical sensor measurements, a customer can decide to reduce the calibration costs by setting userselected default values for various calibration coefficients instead of using the calibration measurements. In this case, enter the default values to be used for the selected calibration method in the coefficient entry fields at the right of the calibration screen. These fields will not be calculated by the chosen calibration method. The calculation is disabled if there are entries for all defaults. Reset Defaults Button If needed, clicking the Reset Defaults button sets the default coefficients to 00 HEX except Gain_B/Gain_T, which are set to unity (2000 HEX ), and Offset_B, which is set to a value related to the ADC offset (A2D_Offset setting). See Table 4.1. Table 4.1 Offset_B Default Values Determined by A2D_Offset Settings A2D Input Range [VREF] A2D_Offset Offset_B -15/16 to 1/16 15/16 1C00 HEX -7/8 to 1/8 7/ HEX -13/16 to 3/16 13/ HEX -3/4 to 1/4 3/ HEX -11/16 to 5/16 11/16 0C00 HEX -5/8 to 3/8 5/ HEX -9/16 to 7/16 9/ HEX 14 of 21

Enter the target bridge readout in % (in this case, pressure) in the Bridge (%) field under Actual. Enter the target temperature in C in the Temperature ( C) field under Actual. Click on Add New Point. The raw data (pressure and temperature) are obtained from the part, and the point is displayed on the large graph. The point is graphed as the values entered in the previous two steps: the X-axis is the target temperature reading and the Y-axis is the target % value. Change the pressure/temperature of the bridge/ ZSC31014 RBic ilite pair being calibrated and repeat. Take as many more points as needed. The program automatically repeats this process for the number of DUT modules entered in the #ASICs field and displays a status window to indicate the progress of the mass calibration. For further details on raw data collection and processing, refer to the ZMDI document ZSC31014 ilite_tech_ Notes_Calibration_DLL.pdf. Hints: For good calibration results, choose the temperature and read-out (%) values as close as possible to the desired working range. If power to the sensor modules is interrupted between taking measurements for different temperature calibration points, click the Get ID button, which causes the software to read the IDs (identifier stored in {Cust_ID0, Cust_ID1,Cust_ID2}) for all the modules so that when it is time to add new calibration points to the database, the software knows the DUT modules indexes in the database. Step 3 Calculate & Write Coefficients After enough data points have been collected to calculate the calibration coefficients, click the Calculate & Write Coefficients button. The software calculates all the coefficients, writes them to EEPROM, and frees up that index for future use. The bridge/ic pair is now calibrated. Before the software starts to calculate and write the coefficients, all raw readings are stored in the caldata.txt file (See section 4.1.2) After calibration is complete, close the calibration window to return to the main display. 15 of 21

16 4.3. Dry Run Calibration: 2-Point Calibration with the MCRs The following directions perform an example of a simple 2-point linear calibration using the ZSC31014 Mass Calibration Reference Boards (MCRs): Steps to the Dry Run Calibration 1. Prepare the MCS by connecting the CB, MCB, MCR, and USB cable as described in section 2.2. Short the K2 jumper on the MCRs (see details in section 2.2). 2. Start the ZSC31014 ilitetester software. 3. Click Find Port to find the proper COM port. 4. Click on START CM. If the setup is correct, the buttons in the lower part of the main window will be activated. 5. Click on Calibration. The calibration window appears. 6. In the upper right section of the calibration window, under Calibration Type, choose 2-Pt Gain_B & Offset_B calibration from the drop-down list box. The smaller graph above the list box indicates the recommended pattern of two bridge readings at the same temperature. 7. Enter the number of sensor modules connected to the Mass Calibration System in the Num Asics field. Figure 4.2 Num Asics Field Enter number of sensor modules. 8. Click on the Initialize button, and click OK to keep the default settings for the dialog box (Figure 4.3). A unique identifier is assigned to this ZSC31014 RBic ilite and is written to its EEPROM. 9. The next step is to start data collection. Normally this would be done with a real bridge attached to the ZSC31014 RBic ilite on a remote board in a controlled chamber. Instead, this dry-run calibration uses the MCR as bridge inputs. a. Enter 10% in the Bridge (%) field under Actual. For this lower value, the shorted K2 jumper provides a 0mV input to the IC. b. Click on Add New Point. The software obtains a raw reading from the each of the parts and graphs the new data point. c. Open the K2 jumper; this corresponds to the input voltage of about 50mV. d. Enter 90 in the Bridge (%) field under Actual. e. Click on Add New Point again. The software obtains a new raw reading from each of the parts and graphs the new data point. 16 of 21

17 Figure 4.3 Intialization for the ZSC31014 MCR 10. Because this is a 2-point calibration, the software has all the necessary data for calculating and writing the coefficients. Click on Calculate and Write Coefficients, which should now be active. 11. Close the calibration window and check for the correct values in the main menu display for each MCR. Enter the number of the ASIC to be tested and click the Select ASIC button (see Figure 4.4). Open and close the K2 jumper, and verify that the displayed measurements indicate a successful calibration. Figure 4.4 ASIC Selection 17 of 21
