Introduction
4 Introduction
The KIT33814AEEVBE Evaluation Board is an easy-to-use circuit board that allows the user to exercise
all the functions of the MC33814 two cylinder small engine control IC. 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) program provides the user interface to the MC33814 SPI port and allows the user
to send commands to the IC and receive status from the IC.
5 Evaluation Board Features
This evaluation board consists of a MC33814 two cylinder small engine control IC, a USB to SPI Dongle
interface, and power conditioning circuitry. All +5.0 V V

• Logic stability guaranteed down to 2.5 V
• Two fuel injector drivers - typical of 1.3 A each
• Two Ignition IGBT or general purpose gate pre-drivers
• One O2 sensor (HEGO) heater general purpose gate pre-driver
• Relay 1 driver, typically 2.0 A, can be used for fuel pump control
• Relay 2 driver, typically 1.0 A, can be used as power relay control
• Lamp driver, typically 1.0 A can also be used to drive an LED
•V
• MCU reset generator - system integrity monitor (watchdog)
• VPP pre-regulator provides power for VCC and V
• Independent fault protection with all faults reported via the SPI
• ISO 9141 K-line interface for communicating diagnostic messages
• Start-up/shut-down control and power sequence logic
• Interfaces directly to MCU using a 5.0 V SPI and logic I/O
• Differential/single-ended VRS conditioning circuit
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.

Installing SPIGen Freeware on your Computer
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
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 MC33814 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 program is installed on the PC and can communicate with the USB/SPI dongle as
described in that kit’s documentation.
2. Connect the USB/SPI dongle to the MC33814 EVB via a 16 pin ribbon cable. Make sure to orient the cable so
that pin1 on both the USB/SPI dongle and the MC33814 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 ON LED on the MC33814
board should both be illuminated.
4. Attach a +12 VDC supply (do not turn on power yet) to the VBAT input connector on the MC33814 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 to the COIL1, COIL2, O2HFB, INJOUT1, INJOUT2, ROUT1, ROUT2, LAMPOUT, TACHOUT, and
ISO9141 output terminals as desired.
6. Launch SPIGen and from the “File” menu, select “Open”, and browse to the location of the “KIT33814SW.spi”
file.
7. Turn on the +12 volt supply and set the KEYSW slide switch to the DOWN position. Verify that all is working
correctly, by observing the VPWR, VPP, VCC, and VPROT LEDs, which should all be illuminated. Click on the
“Extra Pins” button in the SPIGen main screen, then click on the following buttons:
8. Click on the INJIN1 “High” button. The INJECTOR 1 load, INJOUT1, and LED should turn on. Clicking on the
INJIN1 “Low” button should turn off the load and LED.
9. Click on the INJIN2 “High” button. The INJECTOR 2 load, INJOUT2 and LED should turn on. Clicking on the
INJIN2 “Low” button should turn off the load and LED.
10. Click on the RIN1 “High” button. The RELAY 1 load, ROUT1 and LED should turn on. Clicking on the RIN1
“Low” button should turn off the RELAY 1 load, ROUT1 and LED.
11. Click on the RIN2 “High” button. The RELAY 2 load, ROUT2, and LED should turn on. Clicking on the RIN2
“Low” button should turn off the RELAY 2 load, ROUT2 and LED.
12. Click on the IGNIN1 “High” button. The COIL1 load and LED should turn on. Clicking on the IGNIN1 “Low”
button should turn off the COIL1 load and LED.
13. Click on the IGNIN2 “High” button. The COIL2 load and LED should turn on. Clicking on the IGNIN1 “Low”
button should turn off the COIL2 load and LED.
14. Click on the O2HIN “High” button. The O2 Heater, O2HFB load and LED should turn on. Clicking on the O2HIN
“Low” button should turn off the O2HFB load and LED.
15. Click on the Data 3 “High” button. The LAMP load and LED should turn on. Clicking on the DATA 3 “Low” button
should turn off the LAMP load and LED.
16. Click on the Data 4 “High” button. The ISO9141 load should turn on. Clicking on the DATA 3 “Low” button
should turn off the ISO9141 load.
If everything described so far occurs then you are ready to proceed with the remaining examples.

10.1 Example 1: Running the example batch files
1. Click on the “Batch Commands” Tab in the SPIGen main screen.
2. In the box below the “Commands to Send:” column is a pull-down menu box containing several batch file names.
One of these example batch files is labeled “TOGGLE ALL OUTPUTS”.
3. Click on this label to load it. You should see a list of commands in the “Command to Send” box.
4. Click on the “Continuous” button and observe that the loads and LEDs attached to the MC33814 EVB board
are blinking on and then going out in succession.
There are other demo batch examples that can be run and examined for learning how to use the EVB.
