Freescale provides the enclosed product(s) under the following conditions:
This evaluation kit is intended for use of ENGINEERING DEVELOPMENT OR EVALUATION PURPOSES ONLY. It
is provided as a sample IC pre-soldered to a printed circuit board to make it easier to access inputs, outputs, and
supply terminals. This EVB may be used with any development system or other source of I/O signals by simply
connecting it to the host MCU or computer board via off-the-shelf cables. This EVB is not a Reference Design and is
not intended to represent a final design recommendation for any particular application. Final device in an application
will be heavily dependent on proper printed circuit board layout and heat sinking design as well as attention to supply
filtering, transient suppression, and I/O signal quality.
The goods provided may not be complete in terms of required design, marketing, and or manufacturing related
protective considerations, including product safety measures typically found in the end product incorporating the
goods. Due to the open construction of the product, it is the user's responsibility to take any and all appropriate
precautions with regard to electrostatic discharge. In order to minimize risks associated with the customers
applications, adequate design and operating safeguards must be provided by the customer to minimize inherent or
procedural hazards. For any safety concerns, contact Freescale sales and technical support services.
Should this evaluation kit not meet the specifications indicated in the kit, it may be returned within 30 days from the
date of delivery and will be replaced by a new kit.
Freescale reserves the right to make changes without further notice to any products herein. Freescale makes no
warranty, representation or guarantee regarding the suitability of its products for any particular purpose, nor does
Freescale assume any liability arising out of the application or use of any product or circuit, and specifically disclaims
any and all liability, including without limitation consequential or incidental damages. “Typical” parameters can and
do vary in different applications and actual performance may vary over time. All operating parameters, including
“Typical”, must be validated for each customer application by customer’s technical experts.
The KIT33810EKEVME Evaluation Board (EVB) is an easy-to-use circuit board that allows the user to exercise all
functions of the MC33810 circuit. The EVB communicates to a PC through a built in USB port. The Freescale SPIGen
program provides the User Interface to the MC33810’s SPI port and allows the user to send commands to and
receive error messages from the IC. The MC33810 contains four, low side, injector drivers and four custom ignition
IGBT drivers (which can also be configured as General Purpose MOSFET Gate drivers) . The IGBTs and the
associated current and voltage sensing circuits are included on the board to provide a complete working system,
capable of driving actual injectors and ignition coils directly.

Figure 1. EVB Block Diagram
The EVB consists of a 33810 Injector, Ignition Driver (IID) circuit, a USB to SPI interface, a voltage regulator and
power conditioning circuit, a set of 9 Input Jumpers, and 4 IGBTs with voltage and current sensing circuitry. All 5 volt
power required by the EVB is obtained from either the USB, MON08 connectors or the on-board 5 Volt regulator . A
5 position jumper selects which source provides the 5 volt power for VCC (and VDD).
LED DISPLAY
The LED’s are provided as a visual output device for the USB-SPI interface. As configured from the factory, LED 2
indicates when power is applied and a USB connection is established, and LED 1 and 3 are tied to the DATA0 and
CNTL0 lines, respectively, which can be toggled via the SPIGen program.
I/O JUMPER DEFINITIONS (J3)
The EVB contains nine jumpers that connect the parallel outputs of the USB SPI interface to the 33810 inputs as
follows:
If the user prefers to supply the DIN and GIN signals externally, other than from the USB-SPI Interface, the jumpers
can be removed and connections can be made to the open pins.
VCC SELECT JUMPER DEFINITIONS (JP2)
JP2 is a 5 pin, 4 position jumper that determines the source of the VCC voltage. The VCC voltage is a 5 volt supply
that is used by the USB to SPI MCU and the 33810 (VDD). The 5 volts can be supplied from three different sources:
1) An internal 5 Volt regulator connected to VBAT (12 Volts)
2) Directly from the USB Connector
3) Directly from the on board MON08 connector.

Introduction
Output Enable Signal
VDD SELECT JUMPER DEFINITIONS (JP4) -
The VDD jumper is a 3 pin, two position jumper that allows the 33810 to receive 5 volt VDD power from the EVB VCC
line or to connect the 33810 VDD line to Ground to demonstrate the “Sleep Mode”. The Normal Operating Setting
(factory default) is the VDD to VCC connection, pins 1-2 shorted, pin 3 open.
When JP4 is on pins 2-3, with pin 1 open, the 33810 will be forced into the Sleep Mode. (see data sheet for more
information)
VOLTAGE REGULATOR DISCONNECT JUMPER (JP1)
The internal voltage regulator can be disconnected from VPWR to allow the 33810 I
normally connects VPWR to the input of the 5 Volt regulator.
