1 Introduction

This document guides first-time us ers through the init ial hardware s etup, software installation, and basic steps for using the ZSSC4151 IC with the ZSSC4151 SSC Evaluation Kit available from IDT. By following this doc ument, users should gain a quick understanding of the basic operations and options available in the hardware and software and be able to perform a simple calibration and store the results in non-volatile memory (NVM).

Refer to the ZSSC4151 Evaluation Kit Hardwar e Manual for an overvie w of th e hardware, schematic s, and d et ails related to the connectors.

The ZSSC4151 Evaluation Kit consists of the following parts:

• SSC Communication Board (SSC CB) V4.1

• ZSSC415x/6x/7x SSC Eval uati on Boar d (SSC EB) V1. 1

• SSC Sensor Replacement Board (SRB) V2.0

• 6 ZSSC4151 samples (QFN24 4x4mm)

• USB cable

• Vacuum suction pen (provided for safe handling of IC samples)

2 Setting up Hardware and Softwar e

2.1. Hardware Setup

The Evaluation Kit hardware cons ists of th e follo wing three boar ds as sho wn in Figure 2.1 and includes samples of the ZSSC4151 (QFN24):

1. SSC Communication Board – Connects to com puter through a USB 2.0 cable and handles the I (trademark of NXP) and OWI interfaces between the PC-based software and the ZSSC4151.

2. ZSSC415x/6x/7x Evaluation Board. This board contains a socket for the ZSSC4151 and convenient access points for connec tion to instrumentation and e xternal sensor circuitr y. Note the location of pin 1 for the QFN24 socket. Jumpers should be installed initially as shown in Figure 2.1.

3. Sensor Replacement Board – See equivalent circuit in Figure 2.1. This bo ard pr ovides a s im ulated input signal for easy evaluation of functionality without an actual bridge or stimulus. It should be removed when connecting an external sensor bridge (through screw terminals on Evaluation Board).

ZSSC4151Evaluation Kit Start-

With the three boards assem bled as shown in Figure 2.1, attac h the USB cable included in the kit betwe en the SSC Comm unication Board and a USB port on a PC. In some cases, t he user’s operating system detects the board type and autom atically ins talls a driver the first time that the SSC Comm unication Boar d is connect ed. For this reason, the PC should be connected to the Internet during the first USB connection so that the operating system can download a driver. If a driver fails to install, contact IDT for assistance.

2.2. Software Setup

The ZSSC4151 Application Software provides a user-friendly graphical user interface (GUI). It is available for download at www.IDT.com/ZSSC415xKIT

Run the ZSSC415xSetup.exe file from the unzipped location to install the GUI. Launch the ZSSC415x program from the Start Menu in Windows or by clicking the desktop icon created by the installation program.

To enable resizing the window, go to “SETTINGS” on the top menu and check the “No limits on resizing” as shown in Figure 2.2.

. After downloading the software, extract the zip file contents.

2.3. Activating the Hardware Connection

ZSSC4151Evaluation Kit Start-

1. Select I2C™ or OWI (One Wire Interface) from the drop-down menu below “Protocol” (see Figure 2.3).

2. Click the “Connect” button. On the Evaluation Board, verify that the green LED power indicator turns on. The “ACTIVE DEVICES” list on the right side of the “Main” tab menu shows information about the board and device that are connected.

2.4. Creating and Loading the Default Configuration File

1. On the top menu, select FILE > Load GUI Configuration to load a configuration file (Figure 2.4).

2. A default configuration file, ZSSC4151.cfgx, is provided with the software as shown in the “File name” field in Figure 2.4. If necessary, browse to the file location and click the “Open” button.

3. In the resulting “Load GUI Configuration” window, click the “Yes” button to accept overwriting the current configuration settings.

2.5. Loading the NVM Dump File

1. On the top menu, select FILE > Load NVM Dump to load a file containing the NVM data (see Figure 2.5).

2. A default NVM file, zssc4151_nvm.dmpx, is provided with the software as shown in the “File name” field in Figure 2.5. Browse to the file location, and click the “Open” button.

3. In the resulting “Load RAM Dump” window, click the “Yes” button to accept overwriting current data.

2.6. Writ ing the Memory Contents to NVM

1. Click the “Write All To NVM” button to download the NVM data into the ZSSC4151 (see Figure 2.6).

2.7. Taking Measurements

Note: The GUI ref ers to the bridg e sensor m easurand as “ Pressure,” b ut this ca n be any t ype of resist ive sensor signal. The ZSSC4151 is designed for almost all types of resistive full and half bridge sensors.

1. Click the “Start” button to begin acquiring and recording measurements (see Figure 2.7).

2. With the “Pressure” selected in the “Measurements” pulldown, turn the red knob on the Sensor Replacement Board (Figure 2.1). The “Pressure” (Green) waveform plot should move up and down with the knob rotation. The “Temperature” and “Pres sur e Ra w” waveforms can also be displayed using the “Measurements” pulldown selector, but only one waveform at a time will be displayed.

3. Click the “Stop” button to discontinue measurements.

3 Performing a Sample Calibration

This section descr ibes the basic operat ions to perform a sim ple, two-point linea r calibration at a sing le temperature. Higher order calibrations are perf ormed s im ilarly, but with a dditio nal po ints ta ken over the bridg e m easurand and temperature.

3.1. Setting up the Calibration and Acquiring Data

1. Select the “Calibration” tab to display the “Calibration” window (see Figure 3.1).

2. Ensure that the “Calibration Type Settings” and “Acquisition Settings” are set as shown in Figure 3.1. The “Calibration Table” shows that there are only two points required to complete the calibration in this case.

3. Set the upper and lower “Target” limits to 90% and 10%. DO NOT change the “Tgt.Min” and “Tgt.Max” fields.

4. Turn the red knob on the Sensor Replacement Board fully counterclockwise. Select the “P1” field and click the “Acquire Data” button (see Figure 3.2).

5. Turn the red knob on the Sensor Replacement Board fully clockwise. Select the “P2” field and click the “Acquire Data” button.

6. Click the Calculate button. The coefficients for the calibration will be calibrated and updated in the calibration formula textbox at the bottom of the window. HINT: Scroll to the bottom of the textbox so that the “Output” button appears. Move the cursor over the “Output” button. A popup window will appear showing the complete set of calibration coefficients.

7. Click the “Write Coefficients To NVM” button. This will download the updated coefficients to the NVM of the ZSSC4151.

3.2. Checking the Calibration

The calibration can be checked in the “Main” tab.

1. Click the “Start” button in this window and observe the reading to verify readings. If the red knob of the Sensor Replacement Board has been left in the fully clockwise posit ion as in step 5 in section 3.1, the calibration at the “P2” calibration point can be verified by checking that the output for “Pressure” is 90%.

2. Similarly, if the red knob is turned fully counterclockwise, the reading should be 10%.

3.3. Saving the NVM Data and GUI Configuration Settings

The GUI settings and NVM contents for this example can be saved to new configuration and NVM dump files. Select FILE > Save GUI Configuration from the top menu, and save the configuration under a new name. In a similar way, the NVM dump file can be saved using FILE > Save NVM Dump and creating a new name.
