Introduction

4 Introduction

The KIT33816AEEVM Evaluation Board (EVB) is an easy-to-use circuit board that allows the user to

exercise all the functions of the MC33816 Smart Pre-driver circuit. A PC communicates to the EVB

through a USB/SPI dongle (KITUSBSPIDGLEVME) connected to the PC’s USB port. The Freescale

SPIGen (version 7.0 and above) program provides the user interface to the MC33816 SPI port and allows

the user to program the Code RAM and Data Registers, send commands to the IC and receive status

from the IC.

5 KIT33816AEEVM Features

This EVB consists of the following:

• A MC33816 Smart Pre-driver Integrated Circuit

• A USB-to-SPI dongle interface

• Power-conditioning circuitry

• External MOSFETs

•A+3.3V regulator supplies all +3.3 Volt power required by the EVB

•A+5.0Volt regulator supplies all +5.0 Volt power required by the EVB

•A+12V VSUPP supply provides the power to the MC33816 and the loads.

6 MC33816 Device Features

• Battery voltage range, 5.5 V < VBATT < 32 V (1)

• Pre-drive operating voltage up to 72 V

• High-side/ low-side pre-drive PWM capability up to 100 kHz

• All pre-drivers with four selectable slew rates

• Eight selectable, pre-defined VDS monitoring thresholds

• Encryption for microcode protection

• Integrated 1.0 MHz back-up clock

Freescale analog ICs are manufactured using the SMARTMOS process, a combinational BiCMOS

manufacturing flow that integrates precision analog, power functions and dense CMOS logic together on

a single cost-effective die.

Notes

1. In case VSUPP > 16 V, it is highly recommended to disable the internal VCCP regulator and externally supply VCCP.

7 Equipment Required

Minimum equipment required:

• Power supply 12 V with current limit set initially to 4.0 A

• Oscilloscope (four-channel preferably) with current probe

• Multimeter

• PC with Windows XP or above

• SPIGen 7.0 or greater and USB/SPI dongle (KITUSBSPIDGLEVME)

9 Installing SPIGen Freeware on your Computer

The latest version of SPIGen is designed to run on any Windows 8, Windows 7, Vista or XP-based operating

system. To install the software, go to www.freescale.com/analogtools and select your kit. Click on that link

to open the corresponding Tool Summary Page. Look for “Jump Start Your Design”. Download to your

computer desktop the SPIGen software as well as the associated configuration file.

Run the install program from the desktop. The Installation Wizard will guide you through the rest of the

process.

To use SPIGen, go to the Windows Start menu, then Programs, then SPIGen, and click on the SPIGen icon.

The SPIGen Graphic User Interface (GUI) will appear. Go to the file menu in the upper left hand corner of

the GUI, and select “Open”. In the file selection window that appears, set the “Files of type: ” drop-down

menu to “SPIGen Files (*.spi)”. (As an exceptional case, the file name may have a .txt extension, in which

case you should set the menu to “All Files (*.*)”.) Next, browse for the configuration file you saved on your

desktop earlier and select it. Click “Open”, and SPIGen will create a specially configured SPI command

generator for your evaluation board.

The GUI is shown in Figure 3. The text at the top is the name of the configuration file loaded. The left side

panel displays folders that group user interfaces. The interfaces in the pre-installed MC33816 folder pertain

specifically to the board under discussion.The process of loading the configuration file has assigned a list

of “Extra Pins” as well as a list “Quick Commands”, all of which are board-specific.

Setup and Using the Hardware

10 Setup and Using the Hardware

To perform the examples included in the software bundle, the following connections and setup must be

performed:

1. Make sure the SPIGen 7.0 or higher program is installed on the PC and it can communicate with the USB/SPI

dongle, as described in that kit’s documentation.

2. Connect the USB/SPI dongle to the MC33816 EVB via a 16 conductor ribbon cable. Make sure to orient the

cable connectors so that pin1 on both the USB/SPI dongle and the MC33816 EVB are connected correctly, pin 1

to pin 1.

3. Connect the USB/SPI dongle to a PC. LED 2 on the USB/SPI dongle and the USB_PWR LED on the MC33816

EVB should both be illuminated. Reprogram the USB/SPI dongle with the MC33816 USB/SPI dongle image.

The image is version 2.3.1, and is available in the Downloads section of the KIT33816AEEVM web page. See

the SPIGen User's Guide for instructions on how to reprogram the USB/SPI dongle.

4. Attach the +12 VDC supply (do not turn on power yet) to the VSUPP input connector on the MC33816 EVB,

making sure to observe the GND and +12 V terminals. The current capability of the +12 V supply should exceed

the maximum total current that the number of simultaneously ON loads will require.

5. Attach loads (Injectors) to the INJ1, INJ2, INJ3, and INJ4 output terminals (and optionally FP1 and FP2), as

desired

6. Turn on the +12 volt supply. Verify that all is working correctly by observing the +3.3 V and +5.0 V LEDs, which

should be illuminated.

10.1 Running an example program

1. Launch the SPIGen program.

2. Load the config file, by clicking on “File” then “Open” and browsing to the KIT33816AESW.spi file located inside

the “Injector Demo Files” directory.

3. Go to the “Single Command” page in SPIGen and set the RESETB pin high.

4. Go to the “Micro code” page under “MC33816” and click on the folder icon on the right side of the “Code Ram

1” edit box. Browse to the location of the MC33816_ch1.cip.bin file, select it, and click on the “Open” button.

5. Click on the folder icon on the right side of the “Code Ram 2” edit box. Browse to the location of the

MC33816_ch2.cip.bin file, select it, and click on the “Open” button.

6. Continue by selecting the Data Ram and Register files located inside the same directory as the microcode files.

The file names should be self explanatory. After selecting all the files click “Download All” and wait for a

confirmation message. Click on the “Save Filenames” button to save the code and register file configuration.

7. Click the “Enable Flash on CH1 and Ch2” button to run the code. At this point both channels should be

operational.

8. Go to the “Single command” page and set the DRVEN pin high. This will enable all of the pre-drivers and the

DC-DC boost converter should also start regulating. Approximately 40 V should be measured on the VBOOST

output pin.

10.2 Running the example batch files

1. Go to the “Batch commands” page and select the batch file you want to run. There are 5 choices. “Start1”

through “Start4” pulse only one injector (1, 2, 3, or 4). The “Start1-4” batch command pulses all four injectors in

sequence.

2. Click on the “Send Continuously” button and observe that the four loads attached to the MC33816 EVB board

are turning on and then off in succession.

There are other demo batch examples that can be run and examined for learning how to use the EVB.
